Beneath Her Wings (24 Jun 13)
During the run up to Christmas, a very good friend
and flying buddy, Neil Tricker joined me up here in the NW for a
spot of pre Christmas modelling indulgence. The weather was not particularly
kind to us, but we did manage a couple of hours flying at Beacon Fell in the low
cloud / and mist. This was the first time I had flown from Beacon Fell and did
not know, until the day, that a blow of over 15 mph, (it was gusting 25mph) that
conditions get quite turbulent. But this actually increased the level of
enjoyment with the Dreamflight Weasel’s we had prepared. Never laughed so
much….. and no broken models either.
The following day saw us up on Parlick enjoying big sky antics with various
models including a small scale high aspect scale (ish) glider – Speed Astir.
Epoxy glass fuselage for which I produced the plug for the mould, and solid Balsa wings. The model has no moving
tail controls or Ailerons, Instead, it utilised Pitcherons. That’s wing twist
to you and I, which when moved in opposite directions provide roll control and
moving them in the same direction provide Pitch control….. I now have fuselage
to make one of these myself, what a nice model, A full report of the flying
activity can be found on the
www.RAFMAA.co.uk website under “news”. “In the bleak mid-winter”
However, it was during the Wednesday evening (Winter Solstice) that this blog
begins as we discussed the events that we attended during 2011 and what we may
attend throughout the New Year. One
such event which we attend last year was the Leek and Moorland scale fly-in.
Last year I built a 1/5th Scale Pilatus B4, a lovely 3 metre model that really
didn’t take that long to build from the Simprop kit; an excellent first scale
model. Neil has a number of different scale models, new and old. However, for
the next scale event we decided that we needed something different to fly, a
challenge! Something that was unusual.
Having perused the
www.sailplanedirectory.com web site, we came across the SB13 flying wing….
Definitely a shape to drool over. However, as more of the festive liquid was
consumed and realisation that the SB13 may be a little more complex than ideal
for our 1st joint scale venture, we looked for other possible candidates and
eventually stumbled across the Genesis Glider. Still a flying wing but with a
small stabiliser on top of the fin. A little more conventional, but still not
the run of the mill glass ship.
After some significant research over the Christmas
break and a few emails, I received a few photos and a cad drawing of Genesis 2
sailplane from Jim Marske, the designer.
A little tweaking of the CAD drawings with the help from Andy Holden, got me
visualising a ¼ scale project beating up the slopes like in the scene from the
Thomas Crown affair……. At a full size span of 15 metres, ¼ scale makes for a large
(3.75m) but manageable size for a model sailplane. I won’t need to squeeze the
radio in to this one! Yes, one could consider its too big, indeed my partner
took a sharp intake of breath when I demonstrated the size of the model compared
to the Pilatus, even that’s big. But hey, it could be worse; I could have gone
1/3rd scale (5m). ;-) Having discussed such thing as Construction methods, wing
sections etc at length with Neil we are both committed to producing two of these
models. I am to produce the Fibre Glass Fuselage and Neil will produce the wing
cores (Foam) and canopy. Then we will both finish off the wing construction and
assembly on our own, all before the event in August.
This blog will be a periodic progress report on the development and construction
with photos; a disciplined approach to taking photos and notes throughout the
process of building new model from scratch.
A few ideas have come to mind how I can make a plug (Plug - a 3 dimensional
shape from which to make a fibreglass mould).
One such method would definitely be high tech; 3D printing, creating a shape
from polymers using heat or light, or even putting a block of foam on a CNC
machining and rout it to shape. But I do not have the facilities. I have
previously made smaller plugs from solid MDF (Jart / Speed Astir / Dude), but not
wanting to give myself a hernia lifting this one up, as the fuselage will be a
little over a metre long and half metre High, I have chosen to put some sheet MDF around a centre core of foam and carve this to shape....... or that is the
current thought. I need to clear the workshop, so I can give this a little more
thought before I make a start.
watch this space for the Progress on the Genesis
(10 Jan 12) Clearing the workshop.
I have just got a few small projects to finish;
1. Re assembly of the Weasel – I decided to re cover the model as I had used the
wrong acrylic resin on the tissue. Yes tissue, the resultant finish was good,
but not impervious to cold damp conditions, and a coat of exterior varnish did
not meet with my expectations. All done now, just need to pour the radio back in
it. Give me a couple of hours and it’ll be done.
2. Repair of the Speedo Thermo glider that unfortunately met with a mid air with
a “Thing” flying wing during our Winter Solstice outing on Parlick. Just to fix
the tailplane back on now. Another couple of hours.
3. Lastly, finish off a new model called the “Solange” – low wing aerobatic
model. Built up fuselage, foam wings, It is now covered in epoxy glass. I just
need to paint and put some gear in to it. Then its clean down the worktops and I
will be ready to start the new project. A week or so for this one! In the mean
time, My mind is working out how I can progress the Genesis fuselage.
Weasel now finished. Gear Installed, it has come
out a little heavier that the original, but that was to be expected, given that
I had to strip off the old tissue and reapply new covering - just need to
fly it again..
Speedo Thermo tailplane now painted - just need to
glue back on to the fuselage.
Solange coming along, first coat of paint applied
and about to rub down - not sure of the colour scheme though.
Decision made on the
Solange colour scheme, and most of painting now done, just a final rub down
and lacquer required. A few evenings this week should have that sorted and then
the weekend for the Radio installation.
Had a mishap with one of
my shockie models at yesterdays Warton indoor evening. I could repair it, but
it will take less time to make a new one. I hope to take some photos of the
assembly this time so I can pull together an article on how to make the indoor
models with the help of Andy Holden. I can do this at the same time as the
Solange so, it should also be done by the end of the weekend.
Hopefully, I can get the
planning for the Genesis Fuselage sorted and make a start on the Plug next week.
Lots to think about, current thoughts are on how to operate the tail stabiliser
and yet keep it slop free. - now back to the workshop......
now finished Gear installed (but not yet flown) and workshop tidied.
The replacement indoor
Shockie model not complete yet but it wont take long.
I have been tweaking a
few of the fuselage former drawing on the CAD programme in readiness for making
the Genesis fuselage plug.
shockie now finished and lots of photos to support an article on how to build a
shockie - article to come soon.
And So it Begins.....
In the Beginning.........
I've Started by making a tracing of the fuselage profile from the original
drawing, and produce some fuselage former templates and stuck these on to old
cornflake boxes. These will allow me to accurately fabricate the fuselage plug.
Preparation is the key. then I can start to cut wood in earnest. I will keep you
up to date and the project progresses.
click on picture to enlarge
the current bad weather, sleet, snow and fog, it just isn't the weather to go
flying, which has allowed my to concentrate on progressing the Genesis. The
assembly of the fuselage Plug is now well under way. A new bandsaw blade made
easy work of the MDF cutting a total of 10 profiles, now laminated together with
resin. The boring bit is I've now got to wait until this is set before I can
start to carve and sand my creation. Currently the MDF fuselage structure is
under an electric Blanket keeping warm to help the epoxy resin set. However,
Indoor flying tomorrow, so I will not be tempted to take the clamps off early
and make a mess of it all.
I was talking to my old friend Neil - partner in
crime for this project, and he is currently drawing up the wing plan in
readiness for cutting the foam cores next week...... No pressure then! I have
included as promised, a photos of the progress.
pictures to enlarge
I forgot just how much mess you can make with MDF. A builders tub full of
shavings and dust and still more to do –
what great fun. Don’t like having to clean up every half hour or so though.
The Fuselage is finally taking on the sleek streamlined form, however, I was
caught in the act…… Oh, pleased to see you dear………. I was actually sat on the fuselage plug which was the only way I
could hold the fuselage whilst cutting, shaving and sanding it to remove the unwanted
material to finally achieve those curves, honest! I got a cup of tea though.
:-) and a promise to knock next time.
The fuselage is almost there. Some final
sanding and a little filler required.
Next I need to manufacture the fin and fit the wing seats and blend these into
I’ve already made a start on the fin. One side almost done – planed and sanded
to the formers fastened to each end, the fin so far has only taken me about 1.5
hours, got the other side to do tomorrow.
Also need to remove the canopy part of the plug and prepare this to go to Neil
so he can form the acetate canopy. To do this I need to extend the surface area
of the canopy plug about 20mm all way round the canopy seat, then prepare the
surface finish as fine a finish as possible but with no resin, paint or sealer
so he can then work his magic.
I used sanding sealer on a previous project and got into trouble as the vac
forming machine melted the sealer – a bit of a mess by all accounts – kept
sticking to the ABS plastic fuselage he was moulding for me at the time – lesson
News from Neil is that he was unable to get the wing cores cut last week – I
think work got in the way, but is planning to get them sorted by the end of this
week. I will hopefully get some photo of the wing cores when they are done.
Time to clean up the mess once more.
15/Feb/12 Update on the Wings: Neil has cut 1 full set and some of
the panels for the second set before he ran out of foam. Photos to follow soon.
The plug is definitely taking shape; the fin is
now roughly to shape and has been attached to the fuselage. a little more fine
sanding required to get this sorted properly. The wing seat has also been cut and
offered up to the fuselage. its not fixed on permanently yet, as this needs more
work before gluing, then fairing into the fuselage with epoxy filler.
I've had the day off from creating dust today,
however, on a day out with my good lady, we found ourselves walking
past yet another charity shop where I'm always on the lookout for a good pilot.
Julie looked up and saw the next member of the club with a big grin on his face looking down from the
upstairs window of the Help the Aged Charity shop in Buxton, Derbyshire
, was a smiling Postman Pat. A little humour and
tradition of the ninety nine acre wood gliding club (NNAWGC)...(I know Pooh's
gang is from the hundred acre wood, but we must be a wood short of a full
one)......First it was Eeyore now a fully fledged pilot in the Pilatus B4,
Goofy for the paraglider, now its the turn of Postman Pat- just the right size
for the Genesis, maybe?
I've another indoor session coming up tomorrow
evening so another evening off from cutting fixing
However, some work to do in the evenings during this week to
hopefully get the wing seats sorted as the weekend is to get the new wings
assembled and skinned.

Genesis gets wings....
Work has continued on the fuselage plug, now glued the wing seats in place and
done a little more sanding, but not as much
progress as I would have liked - had a few days off to catch up with other
things. However, on Friday I packed the car with vac bagging equipment, a few
blocks of foam, and of course, a few models both slope and indoor, just in case..........
and set of on the 3 hour journey with my very understanding partner to the slope soaring
Mecca of England.........
Lincolnshire. No not really the slope soaring Mecca, there is only one hill and
that's got a Cathedral on top; Lincolnshire is particularly flat. The main
purpose of our weekend away was to get the Genesis wing panels assembled and
veneered. Neil and Sue's hospitality is second to non, and on arrival a good
glass of beer and a lengthy catch-up chat, I think you can guess the subject,
at least between Neil and I. Our two partners, had other things to chat about,
being interested in mostly the same type of things as each other.
Saturday morning and the two girlies were up and
out for some retail therapy leaving Neil and I to attack the foam in the
workshop. The wing panels had already been cut and to my surprise, Neil had
already put in the shear web part of the main spar and also installed the tubes for
the wing joiners - Excellent job. So all that was left was to lay out the glass
cloth and wet out the carbon.
The covering for the wing comprise of Obechi
veneer a layer of glass cloth cut on the bias at 45 degrees between the foam and
veneer and carbon tows wet
with epoxy and laid into the rebate on the wings above and below the vertical shear web spar. Carbon reinforcement over the wing tubes,
together and vac bagged.
Having got one wing sorted in a couple of
hours, what was left for the day was to get some fresh air. A well earned brew
and a quick bite of lunch and we packed the car to venture across the border
into Leicestershire - just an hours drive away to check out Burrough hill, about 5 mile
south of Melton Mowbray. The wind was a Westerly, with an element of north from
time to time. Needless to say, we had a good few hours of Weasel and Wannabee
fun - two brilliant foam models. just right for the chosen slope. Coffee and Crimbles'
and then home for an evening out.
Sunday morning saw us rushing to check out our handy work from the day before;
a freshly bagged Wing. Back inside for Cereals, Croissants and Coffee, then on with the gloves to
sort the other wing.
The second wing was efficiently dealt with,
having had a good run through the process the previous day. Neil prepared the
Carbon tows for the leading edge whilst I arrange the veneer. We then worked
together to apply the carbon leading edge to the foam core. I then prepared the carbon
spar tows, while the glass cloth was laid out and rolled
with epoxy. The spars rebates were filled with carbon and rolled out in next to
no time and everything sandwiched up again for the vac bag, again, all before
lunch. The girlies had gone off to some craft fair, so what else could we do but
have a spot of lunch, and go to RAF Digby to make use of their fantastic
gymnasium that is situated inside a huge hangar. No one else around so out with
the shock fliers and a little indoor flying.
The day activities precluded with dinner - as I said Neil
and Sue are such good hosts, followed by coffee and pudding. Then we packed the car for the
journey home to Lancashire. Having had a really good weekend in more ways than
one, we arrived back to the Preston area to be met with rain; Oh, what a
The wings are still with Neil, as he has
offered to prep the wings further and cut all the necessary holes for the
servos, airbrakes etc. Another trip will ensue soon to get the 2nd set of
wings sorted. Hopefully the pictures
will give you the story so

News from the workshop.......Neil has been busy.
The build of the first set of wing is done. They now need covering in glass
cloth and resin, the ailerons have to be cut out and the gear installed. The
second set of wing cores are now done, the shear web and joiner tube are being
this week, so I will have to arrange a trip to get the second set of wings in the
vac bag and
bring my wings back here for completion.
canopy plug was taken to a secret workshop somewhere in Norfolk............ and
as expected, the first acetate formed from it produced a few flaws in the
However, the plan was always to produce a really clear canopy so aluminium powder
and resin has now been poured into the first moulding. When fully set this will be
smoothed and polished. This will form the new plug from which some serious vac
forming should take place. fingers crossed!
The fuselage plug is getting lots of TLC. it
has been coated in numerous layers of sanding sealer and sanded back to quite a
nice finish. this is undergoing further work. It needs to be painted and worked to get that shiny silky
smooth finish required for the mould. This will take a little time to get it to
the finish I require.
Whilst all this has been going on, Neil and I
have been getting out in the fresh air up in the Lancashire hills. Yes, he
popped in, as he was just passing..... on the way back from a weeks holiday in
the Lakes. The weekend was blessed with fairly good weather, a few showers on
the Saturday, a little snow on Sunday, but you have to make the most of the
weather and good company. I test flew my new Solange glider (see 24/1/12 on my
blog)- what a lovely
smooth aerobat; It took me back to my powered aeros days, flying a Ken Binks
Adagio. The Solange is a nice relaxing but very capable aerobatic machine. it
wont be hurried, it does everything at a constant speed, but does it all with
such Grace. If you fancy actually building something and have a really nice
machine to fly around and at just £68 including Posting, its a bargain. see more on the
I'll Report on further progress of Genesis soon.......
There's been lots of fettling of the fuselage plug
since I last updated you on my progress. I coated the plug in a number of coats
of Filler Primer, cutting
back each time. Once I was happy with that, I then gave the whole plug a couple
of coats of white primer. This then, as expected showed up some imperfections in
the finish. further cutting back with 1000 grade wet and dry, followed by 2000
grade wet and dry. More paint, then cut back again. Finally, using rubbing
compound (T Cut) to get it to shine. Again this revealed some slight pin holes.
More paint, more cutting back..............you get the idea!
I have now got to the polishing stage. Many
coats of polishing wax to apply, buff up and reapply. each time getting more and
more high gloss finish.
Whilst the photos show a nice white colour, the
actual model has a few patches of the yellow showing through, this is where I've
had to rub back to remove other imperfections. But this has now resulted
in a very smooth finish. I don't think I will be applying any more paint. Hope
not anyway, As I am adding a few coats of wax each night now.
I have also cut out the frame in which to mount
the plug ready for the next stage of making the mould. I reckon the moulding
stage is only couple of weeks away, so watch this space.
Update on the Wings........
I have been summoned to Lincolnshire to help
with the second set of Genesis Wings, much like before. But I will be bringing
my own wings back with me this time. This will be the first time the plug and
wings have been together. So I hope to take a few photos to whet the appetite so
to speak, before I make the mould. In the mean time I'll keep polishing.
However, in between coats of paint / rubbing
compound/ polish I have moulded up another Dude fuselage for a friend. (see My
article on the dude ds from the club news menu). Its had time to cure and has
now been popped out of the mould. got to remove the swarf from the seams then I
can deliver it. The reason for showing the dude mould photos is to give you some
idea of what I need to make next. The two clamshell - like items in the photos
below are the moulds. the Genesis Plug will allow me to make these, but I will
probably be making the genesis mould a 4 piece mould. All will be revealed why,
See you soon.
A recent holiday up to Scotland has
meant that work on the Genesis stopped for a week or so. Although I took
a couple of models on holiday, always keen to get some stick time, I
didn't get to flying them as the weather got the better of us; Edinburgh
castle was in cloud for most of the week, rain, snow, then a lack of
wind making sure that the models stayed in the car.
On our return home, a quick stop over, and then off to Lincolnshire to
help Neil with the other set of Genesis Wings. These were laid up with
the required carbon and cloth and vac bagged last weekend. We also took
the time to prepare and vac bag the new glider tug wings, this will be a
bit of a beast powered by a 45cc petrol engine. The wing cores are 3”
thick and 1.6Kg each…Its Big! Possibly more on this project later.
The Genesis Fuselage plug has had a few more touch-up coats of filler
primer to the fin, but it has now been polished and has been laid in the
mount in preparation for making the mould. I am in the process of filling
the gaps around the plug with plasticine to complete the process.
I have decided to make the mould in 4 pieces because of the fine
trailing edge to the wing seat. If I made the mould in two halves, I
think I may have problems extracting the model out of the mould.
Therefore, for the purpose of removing the fuselage, and plug for that
matter, I will be making each side of the mould also split along the
wing chord line. More work, but it should ensure that the model can be
extracted from the mould intact
Last night I finished the plasticine work and installed the flange that
will help form the join of the mould along the chord line (photo 2). A little more
therapeutic polishing is required and a coat of PVA release agent and I
will be ready to start the moulding process.
I took delivery of some new Gel coat (decorative surface finish)
yesterday as I wasn’t sure if my old stock was still any good. I hope to
apply the Gel coat, followed by numerous layers of chopped strand
fibreglass matting of various grades this coming weekend.
It gonna get messy!!!
Finally finished polishing, at least
for now anyway. A coat of PVA release agent was applied
last night. This evening has been fun...... getting a little messy with
the gel-coat which is now curing. (that's the grey paint like effect in
the photo 3). The Gel-coat provides a really nice base and decorative
finish that can be polished. This will be the surface you will see on
the inside of the mould.
1st thing tomorrow, its back to the
workshop and make a
start of applying the layers of glass matting and resin to build up the
mould. The glass matting of various grades has been cut to size for
each quadrant of the mould and is stacked neatly to one side in
on the first part of the mould is
now complete. Multiple layers of various grades of fibreglass tissue and
chopped strand mat which were built
up over the last two days, a couple of layers at a time, a couple of
hours between each few layers to ensure the resin didn't go Exothermic.
Wouldn't want everything getting too hot! The last of the layers went on
last night, and then tidied up and cleaned everything. Resin and glass
fibre gets everywhere!
touching mould this morning, instead the weather was good, and the wind
was on Jeffery Hill, the sun was even shining so I went to get some
stick time. Took the Smart, Solange and even the scale Pilatus B4. I
flew everything, so definitely a good day!
On my return and after the weekend
chores, cut the grass, clean the cars...... you know how it is, I was
back in the workshop to check on my handy work and to prep for the next
stage. This involved trimming the lose glass around the edged and
removed the plastic flange along the wing chord - I was surprised how
easy this actually came off - obviously the right amount of polish and
release agent. I have now made some indents in the flange as a key for
part 2 of the mould and cleaned everything up. Its now had a couple of
coats of wax polish and I have just sprayed it with PVA release agent in
readiness for laying up the next bit.
A day off tomorrow, as I'm going indoor
flying. See you soon.
|Not quite a day off from the workshop
on Monday evening. Yes I went to the indoor session as usual and had a
good time, although I did feel that I was being singled out for target
practise, me physically……… I just seemed to be always in the way!
Anyway, on my return home, I quickly put everything away and made my
excuses to venture into the workshop to apply the gel-coat to the plug
in readiness for laying up on Tuesday evening. Early away from work
Tuesday and applied few layers of glass tissue before dinner.
Thereafter, I applied three more layers of 100g chopped strand mat,
which went on really well. Again, it took a while to clean up to make
sure my tools would not seize up with resin and also to get rid of any
waste. I do like to jump straight in to the next phase each day rather
than having to clean up from the day before of have to undertake work in
a messy workshop.
Tonight its back in the workshop to finish off the 2nd part of the mould
with additional layers of glass up to the required thickness. Then I can
take a breather until the resin has properly cured. By the weekend I
will be able to release the plug and moulding from the mount turn upside
down to expose the right hand side and repeat the process for Parts 3
and 4 using the new moulded flange as the mating surface.
|I can finally stop holding my breath,
as all is well!
Today I finished
off the supports to the outside of the mould so it will stand up on its
own on the bench, and once cured, I removed the mounting board support
that the whole assembly had been resting on for the last week or so and
some of the plasticine from the underside. Turned the whole thing over
and with the minimum of pressure, the mould came away from the mounting
board clean. (start breathing again........)
A little trimming required and a good
polish and I can start to prep the 3rd part of the mould. Basically, a
repeat of what I have just done, but using the flange on the LH mould to
form against. Again, Its going to be a busy
and messy weekend ahead.
|Having completed the LH side of the
mould I realised that I was running low on resin, I certainly didn't
have enough to complete the RH side and therefore Thursday saw me
putting an order in over the internet for some more. This gave me an
excuse to take Friday off work
to await its delivery. This also gave me plenty of time to
progress with the 3rd part of the mould. Thursday evening saw a me spray
a coat of PVA release agent on to the lower RH part of the Plug, and
before retiring for the evening I applied a coat of Gel-coat.
Friday morning was a leisurely affair,
I had a few task to do with the website, but by around 8:30 these had
been done, including uploading a number of articles for the club news.
By 09:00 my new order of resin had arrived, what great service! I laid
up a few layers of tissue and let it cure onto the gel coat. After lunch and in to late
afternoon more layers of fine chopped strand mat, were applied.
The next day, Saturday, I awoke early and couldn't get back to sleep,
the morning chorus of bird songs were just too much! So an early
Breakfast and into the workshop with my mug of Tea to apply a few more
layers to the mould.
My good lady also awoke earlier than normal
due to the smell of resin permeating into the house....Oops......
Anyway, doors shut and window open sorted that out. By this time, I had finished the
first few layers and so after coffee and toast we ventured into town earlier
than planned. After a leisurely trip around the shops which was not
complete until I had visited the model shop, we stopped in at the local
garden nursery for a quick look around and a spot of lunch, after which,
it was back home and changed for the final session on part 3 and applied
the last of the layers of course chopped strand mat.
Its now Tuesday evening and the plug
and mould is ready for part 4 to be fabricated. It has been polished,
had the pva release agent applied and a coat of gel coat. This will cure
overnight allowing me to start laying up the final part of the mould
The word from Neil down in
Lincolnshire, is that both sets of Genesis wings are sorted. This means
that they have been trimmed, sanded and the recess for Servos and
Airbrakes have bee routed out. I just need to finish the fuselage mould,
create a fuselage and then we can meet up to do a swap, a fuselage for a
set of wings - I reckon that's a good swap. He has also finished polishing
the new plug for the canopy and he informs me that he hopes to vac form
the canopies tomorrow.
That's it for now. I will be busy again
tomorrow and I will report back when the mould is complete. Hopefully by
the weekend, I will be ably to split the mould and extract the plug. A
time of excitement and apprehension. watch this space!
|Friday evening and the job is
Final two layers of
course glass fibre has been applied to the mould. It has been trimmed to
shape and the wooden ribs have been cut and glassed in place so that
each half of the mould will stand steady on the bench. These have been
weighted down and are now curing.
More trimming to do tomorrow and then
probably tomorrow evening or Sunday, I will be able to split the mould
into its component parts and extract the fuselage plug. We will see just
how much work is left once this has been done. I will of course, let you
A Fuselage Mould is Created !!!!!
|Saturday morning 28/Apr/12 ,and everything
was nicely cured, but so I didn't attack the mould too early, I ventured
out into town with my good lady to get supplies. However, on our return
and after a spot of lunch, I was just itching (from all the GRP glass
dust), well that as well, itching to see if the mould and fuselage plug
were able to part company. Having trimmed off the excess glass from
around the joins I set to carefully inserting wedges of wood into the
join to separate the four individual moulds from the plug. The
first part let go very easily. and so did the second part. That was one
full side away from the plug, nice and clean too. The second half was a
little more troublesome. The top rear part of the mould of came off
clean with a little warm soapy water and little
teasing, but the lower part was having non of it. More water , a little
trimming around the canopy line but still not really giving. A few more
wedges, and soapy water applied to the gaps, and with my patience
waning, a little more force........... and the plug was free.
A little damage to the plug's surface
finish, but sometimes this is expected. The plug is good around the
belly, so another new mould to fabricate the undercarriage doors is on
the cards, and with a little tidying up, I may also be able to fabricate
a mould for the canopy frame...... but they will be for another day.
I feel like all the effort has been
well worth it. The mould need some trimming and cleaning up, and the
inevitable polishing, but I am really looking forward to this. For now I
feel like a proud dad. That's it for today though, I'm out tonight to
07/May/12 - The Layup
|Unfortunately the BAESMAC website has
been off line due to a server problem for a week, so I have not been
able to keep you abreast of my progress. However, I write in retrospect,
starting with last weekend 10 May, to present day......
Last weekend, over the bank holiday, saw
me cleaning up the mould and doing a lot of polishing. A coating of PVA
release agent to the four parts of the mould on early Saturday morning.
After lunch I applied the Gel coat and then had to wait for this to go
"green", before I could start laying up the glass cloth into the mould.
I first started laying up the area of the trailing edge fairings
requiring to put in a layer of cloth, then micro fibres before
assembling the two quadrants of the mould to make up each half.
Then starting off with the fine grade
glass cloth I methodically progress wetting out the cloth easing it into
all the wing seat areas, again using micro fibres and resin to fill in
the small gap at the trailing edge fillet. two layers of 160g cloth
followed by a 300g layer to the main body and of course the Carbon cloth
in the fin - that's the black area you can see in the photo.
Having laid up both sides of the
fuselage I then had to wait for these to go "green" so I could trim the
excess cloth and resin to allow me to join the two sides. The clock was
ticking, it was already 8pm and I had not trimmed or joined the fuselage
halves. However, by around 10:30pm, maybe more like 11pm, the resin had
gone off enough to allow a sharp knife to cut through the cloth and
resin cleanly, just life a knife cutting through firm butter. This is
what I mean by going "green"....
A strip of wetted out glass cloth was
then laid inside the fuselage on the join and the whole thing bolted
least this size of fuselage allowed bigger tools to be used to fully wet
out the joining cloth and make sure everything was ok.
11:45pm and it was time to clean up. I was very glad that the Job was
finished, I was tired, it had been a very long day, somewhat frustrated
and how long it took to lay up the cloth, but pleased with the overall
I only ventured back in the workshop
the following morning to make sure that the resin was curing properly
and everything was ok. Then off for the day up to the lakes with the
missus and a well earned rest.
10 May 2012 - Genesis is Born
|Moving on to today, Thursday 10 May 12
and over the week, I have been busying myself with working out how I
might construct the canopy frame, a few experiments later and I think I
have worked out the method. This is something to accomplish over the
coming weekend, and I will report on this in good time. However having
been eying up the fuselage still in the mould..... I felt it was
all the bolts holding the mould pieces together, I started to
methodically insert wooden wedges into the joins to separate them. This
is a time of anxiety! It needs quite some force to be applied and
teasing to get the mould to give up its hold on the content and the odd
cracking sound makes you hold your breath. Finally mould released bit by
bit to reveal it contents. The final part of the assembly is always the
most resistant to release. I reassembled everything around the fuselage
again, bolting it all together to get some leverage on the final
quadrant of the mould. It worked. A final loud crack and the mould gave
in to the tweaking. Everything quickly unbolted and the component parts
pealed away for reveal a perfectly formed Genesis. Relief all round!!!!
Genesis is Born!!! Sweet!!. and a
healthy 900grams. I can finally breath again. here's some photos of the
See you soon :-)
the last 10 days I have been experimenting with canopy frames for the
Genesis fuselage, also experimenting with a cockpit moulding and of
course, preparing the mould in readiness for fuselage No 2.
I met up with Neil at a Control Line event this weekend at Barton
Aerodrome near the Trafford Centre, Manchester. I found my way to the
modelling site which, without the help of a modeller that I spotted with
a hatchback full of Control Line models I would never have found. Once
at the site I met up with Neil and another really good friend, Paul
Blakeborough who was the other part of the Control Line double act. It
was almost like a scene from the 'minder' series, exchanging goods in
the middle of nowhere, where no one can see.....ere, what you got there
No dodgy dealings here
though, and there were witnesses.
While I was extracting the
Genesis fuselage from the back of my car, another aeromodeller, and who
happened to be, a full size glider pilot stopped and said...." oh,
it's a Genesis". Well, I was impressed, and I must have done something
right if someone can recognise the aircraft without its wings. Anyway, I duly handed over the fus, canopy frame and cockpit to Neil,
and in return he handed me a set of wings, a joiner and a couple of
canopies. A good swap I reckon.
Back in the workshop I had already treated the fuselage mould to a
coating of release agent the day before, and late Saturday evening I
applied the gel coat. It was difficult to get to sleep that evening,
Have I mixed the gel coat correctly, have I got all the glass cloth
ready, Hope its not another 14 hour marathon......... you get the idea.
The birds woke me early, we have a few friendly chaffinches that like
collecting bugs and other small insects that gather around the
window and door frames. and they continually flap around and peck the
windows.... Needless to say, I was up at 6 am Sunday morning, quick
breakfast and took a cup of tea into the workshop. By 9am I had laid up
the Genesis fuselage and also a Dude flying wing fuselage. Excellent
work! By 9.30 am I had cleaned up and was enjoying coffee and toast.
in the afternoon, My daughter came around for a chat and a favour, but I
made the request first, she made me a nice cup of tea as I had trimmed
the glass cloth and was already mixing resin to join the fuselage sides.
A good chat a spare pair of hands and good brew allowed the
fuselage to be assembled in good time. I left the Dude mould until
later, as this is more like micro surgery and it needs to be put into a
jig to align the carbon tail boom, all was completed before dinner and a
Both fuselages are now curing and although its now been over 24 hours
and all seems dry, I always like to leave them for a good few days
before I split the mould. Thursday is the day! so watch this space. I
hope that if the weather is good, I can offer up the wings to the
fuselage and take a photo as a treat.. and to whet the appetite for the
remainder of the journey.
See you then.
Genesis 2 is
It's been an anxious week waiting to
see if the second Genesis fuselage would turn out ok, having laid up and
joined the fus at the weekend.
Well, I shouldn't have worried as Genesis 2 fuselage came out of the
mould fit and well at a healthy 850g. The mould released its prize easily, the last part always
being the most difficult to release, but a little brute force did the trick, and all
this was before
As I suggested the last time I gave you
an update, I decided to get the wings and put them at the side of the
fuselage to get a feel of the actual size of this 1/4 scale project. As
you can see from the photos, its looking good, all 3.75m of it. Even the
NNAWGC (Ninety Nine Acre Wood Gliding Club) team are drooling over it. See for yourself.
I now have a canopy frame to make and the cockpit
interior. then finish the wings and fuselage and of course the Elevator
which will sit at the top of the fin.
Further updates to come as it
Genesis - the other one...... 19 Jun 12
Apologies folks, but it has been a while
since I updated you on the progress of Genesis.
Things have progressed slowly over the
past week or so. I have been experimenting with different canopy frames
(moulded), which I have not been totally happy with. However, canopy
frames aside, I have now married up the wings to the fuselage and this
week, I need to concentrate my efforts on finishing this off. I also
need to get the airbrakes installed in the wing and make the wing tips.
If all is well and I achieve what I have planned, I hope to make the
tailplane at the weekend, although I do have plans to attend a flying
event on Sunday, so this will probably be a job for early next week.
my partner and I spent last weekend down in Lincolnshire with Neil and
his good lady. The main reason for the visit was to attend a Royal
Philharmonic Orchestra concert in the grounds of a Stately Home on
Saturday evening, there was also to be a Spitfire flying aeros to the
music – hence the name of the event “Spitfire Proms”. The bad weather
(Low cloud, high winds and rain) grounded the BBMF spitfire, but half
way through the concert, despite the weather, we had an aeros display
from the "Blade" team in their Extra 330’s, with just enough height
below cloud base to perform their normal routine. Lots of drift due to
the gusting 30kts cross wind, but a really excellent display!
The sea of umbrellas between us and the stage was also a sight to
behold. But the mix of good food (Picnic) good wine and excellent music
and a fishing shelter to hide in, made for a memorable evenings
saw us in Neil’s workshop inspecting his handy work on his Genesis
model, which has been progressing well. The wings are on, canopy frame
made….. (I think I will be copying this design), rudder post installed
and glassed in with integral servo mount and the tailplane has been made
and has now been mounted on the fin. All the things I need to do this
week….. I need
to catch up!
It is hoped that we can get both our models test flown at the end of
July, which has always been the plan, and I think that we are still on
track to achieve this.
Photos of Neil’s Model
28 Jun 12
met up with Neil on Sunday at Leek and Moorland slope site in
Staffordshire, for an organised fun fly event, some 2 hours drive away.
The weather was a little wet to start with but got better albeit a
little blustery as the day progressed. We took part in the fun
competition, loops, rolls bunts, pylon race and whilst most used foamy
flying wings, Neil and I flew the "Dudes". No we didn't win but we
certainly created some interest in flying something a little different.
Once the competition was out of the way, off the peg flying took part
with lots of mouldies taking to the air and again Neil and I both flew
the Dudes, better than in the comp and also aired our "Jart" models such
were the conditions.
News from the Lincolnshire is that Neil's model is progressing well. All
flying surfaces have now been glassed in 49g cloth and epoxy resin. This
leaves me well behind, although I have made some progress.
The airbrake boxes have now been installed, wingtips formed and stuck in
place and the whole wings sanded and some filler applied to get a better
surface finish. I note from the many photos out there of Genesis II,
that the aircraft has part of the wingtips angled upwards, so I need to
estimate how much and embody this detail. My tail stabiliser has been
made from balsa and I have been working out the method of fixing this in
place on the fin and ensuring a suitable linkage - not quite finished
Other jobs to do is make the rudder , of course Neil has this already
done and glassed..... I need to install the tail servo mount and rudder
post, then create a suitable canopy frame. Doesn't sound much but it all
takes time to get right, not always first time.
More updates to come
11 Jul 12 -
The small things seem to take the longest time to get sorted.
My Genesis has been progressing, albeit slower than I expected. The
fitting of the tail plane is now complete and I am happy with the
control linkage that I have fabricated. This is made from laminated
fibre glass board. Cut to shape and profiled to the tail. Unlike the
full size aircraft whose tail plane fits on from the rear, I was having
problems coming up with a suitable design that would allow retention of
the flying surface and to provide the control movement required whilst
having enough strength to withstand the flying loads. Instead, I have
opted for a tail plane that plugs on from the side and the control
profile being sandwiched between the two halves, the join being hidden
by tape. The actuator mechanism will be retained within the fin on
removal of the tail plane.
The tail will be controlled by a servo mounted in the base of the fin,
and the mount for this has been installed. The Rudder post was next to
be made, this is in the form of 1/16" ply backed by 3/32" x grain balsa.
The whole thing was cut and sanded to shape and epoxy glassed in place
with a suitable gap for access to the elevator servo mount. Now this is
full cured, the whole fin is very strong with no signs of any twist .
number of areas required a little filler and sanding and this is also
complete. Tonight it is assemble the model, make sure everything is ok
and the wings mate well on to the fuselage and then I can start to Apply
the glass cloth tomorrow.
An update from Lincolnshire,
Neil’s model is now fully covered in 49g glass cloth and epoxy resin,
due to some slight imperfections in the fuselage moulding in the form of
air bubbles in the Gel coat (how embarrassing), this has had to be cut
back with wet and dry and the air bubbles filled - a little P45 car body
filler has done the trick. The problem was only over an area of about 4
square inches, so not disastrous. He has also been cutting out the
ailerons and dressing the wing and ailerons with epoxy and micro
balloons. A text message last Friday stated that the canopy and frame
have now been fitted to the fuselage. Another text message on Monday
stated that Neil has now started to paint his model.
The clock is ticking, but there is no point in rushing. It will be ready
when it is ready! More updates to follow.
couple of days ago, I received an email from a fellow modeller in Spain,
Rafael Sanz who found our website and my Genesis blog purely by chance.
However, the best thing here is that there is a whole community out
there, Rafael being one of them, that is in the throws of building their
own Genesis 2 models. Rafael's website is quite informative and
also provides some links to other Genesis web pages. The website is in
Spanish though. However, If you put the following web address into
google, you can have the page translated for you.
http://tallerdedalo.es/web/Genesis-2D Technology, isn't it
Rafael's model is almost complete which he started around the same time
as me back in January 2012. The model is a little smaller at 1.6m. Visit
the website via the google translate if you want the detail, otherwise
the photos will give you a flavour. Hopefully I will get an update of
how it flies is good time. Good luck Rafael.
Well, It time to venture back in the workshop for an hour. see you soon
12 Jul 12
Here it is, Genesis in the flesh so to speak..
have now cut all the glass cloth ready to finish the wings and tail
plane and rudder this weekend.
16 Aug 12
Apologies for not updating my Genesis blog for
To be honest, I think that the amount of
work that has been done to get the Genesis to this point, burning the
candle at both ends so to speak, I
reckon I must have over done it a little, and given the fact that some
of the more intricate jobs were not going so smoothly at the time, I
found myself getting distracted.
As I a keen cyclist, I found
myself distracted by the Tour de France, and the Olympics. I have also
produced a "Mistrale" kit (a swept back version of the Dude flying wing)
for Ron Ovenden. I have put a few finishing touches to a new and much
sexier looking glass fuselage to an old design of mine - Wotsit flying
wing. (Named as such because everyone kept asking me - what is it?
- wot is it - wotsit)
All that and a few extra hours at work
prior to going on a flying Holiday last week in South Wales (Awesome
lift on Rhossili Down), I have done very little to the Genesis since my
last update. Phew, not enough hours in the day - I can't sit and watch tv
for too long, especially when the day job requires me to sit at a
computer most of the time as well!!!!!! So here I am batteries recharged
and motivation on the up.
The Genesis wings and flying surfaces
are now covered in glass cloth and
epoxy, although there is a little extra work to do to the finish of the
wings as a few bubbles appeared under the glass cloth on the top surface
during the curing process. I have subsequently rubbed the wings
down and filled the holes. But I now plan to put an extra thin layer
(25g) cloth and epoxy over this. I don't think the extra weight will be
last night I was fettling a new cockpit interior for the Genesis in foam
ready for a layer of glass cloth and by doing so, renewed my
enthusiasm to complete the Genesis project.
This weekend should get me even more
fired up as Neil has finished his Genesis and I plan to join him at the
Leek and Moorland scale competition this coming weekend to test fly, as
well as enter our other scale models.
As I mentioned earlier, I went to
Rhossili, near Swansea on the Gower peninsula in South Wales last week
and had a really good time. We rented a cottage for a week just 2 miles
from Rhossili. Both Neil and I went flying whilst the girls went off and
did girly things........
If you can imagine a 400-500 ft 45
degree slope westerly facing range of hills and a 15 mph wind, with
nothing but sea and sand in front of it - it just produced some of most
smoothest lift I have ever flown in. The lift stretched out so far even
the Quarter scale models were getting a little too far away for comfort,
but the lift was still good. I was flying the Pilatus B4 around with
such grace. Big sweeping turns, loops, roll (well it is a scale model of
an aerobatic glider). Pretty impressive! On our first full
day we flew from around 10am until we watched the sun going down around
7:30pm. A wonderful day resulting in Flat batteries. as a sun downer, it
was back to the cottage for Tea and medals, well, a nice cold beer
Yes, I will be going back!
We had a few days where the wind
direction was not blowing on to Rhossili Down, with
much lower wind speeds, but cliff top soaring in marginal lift conditions
is challenging but extremely
rewarding. The last day and on the way home, we stopped off at another
fantastic slope site used frequently by the slope
racing competition fraternity, but one where we had flown may time before. This time an
Easterly facing site on the "Bwlch" overlooking Treorchy down in the valley.
This time the wind was was gusting around 25mph onto a shear cliff face
of around 300 ft with a rounding slope leading from the valley floor up
to the base of the cliff. As common with very steep hills, there is a
rotor (turbulence) on the top of the hill, making ladings tricky, but
the landing area was pretty big so we could move away from the major
However, having put the Dudes and Jarts together, we enjoyed a couple of
hours of BIG AIR. 60 inch models
undertaking inside and outside and knife edge manoeuvres that were so big, that any
powered flyer having a stir of the stick would have been converted to
slope soaring instantly. Any powere flyers reading this should really
have a go. When the wind is a little too strong on the powered field,
get up the hills, its Great Fun!
Anyway, I will update you after the
weekend adventure at Leek and Moorland with hopefully some photos and a
video of the first flights of Neil's Genesis.
Till then, Happy landings
18/Aug/12 - First Flight Genesis 2#2
Smiles all round.....
Yesterday I joined Neil at the Leek and
Moorland Scale Competition. We took a number of models, the Libelle, ASK
and the Pilatus, but the real show stopper was Neil's Genesis 2
Once the rain had passed, much later
than forecast, we decided to commit a few models to the air. The wind
was slightly off the slope but the lift was ok, but not in abundance. As
the afternoon progressed, the wind came round to be on the slope, but it
still didn't give the amount of lift we expected. (reckon we had been
spoilt by or holiday in Wales)
The Genesis was assemble, and soon
became the the topic of conversation. Controls were checked, programming
tweaked, then checked again and it was time to make the decision. Fly or
not to Fly? Neil made a quick decision and armed with a Camera/video,
which I gave to someone else to film the launch, all was set.
The fuselage is pretty wide, so I went
armed with a surgical glove. Not for anything sinister, although I
thought I might have to help Neil with his bicycle clips...........
Seriously, I was not taking any chances with the launch. The glove was so
that I could get a good purchase on the fuselage and so it did not slip
out of my hand when I launched it.
Controls checked, clear above and
behind...........A quick run up and good positive push forward and the
Genesis was away.......... Wow! A few clicks of down trim was all it
needed to fly straight and level. During the flight the stall was
checked and did not provide any surprises. Stall was straight with no
wing drop. The Centre of Gravity seemed a little far forward as the dive
test proved, but we were airing on the side of safety for the first
flight. The model looks good in the air. See for yourself.
Neil had two flight with Genesis during
the day, and has now gone home with a few idea and things he want to
tweak before we take it along to the Long Mynd scale Fly-in in
September. I don't know if my Genesis will be ready by then. I have to
do some repairs to the Pilatus, having had a mid air with another Pilatus at
the Leek and moorland event.
We need a better day to take more
photos and show the Genesis off to its best potential. It was certainly
a talking point though.
And on a humorous note, Tigger (the rooky pilot)
and new member of the Ninety Nine Acre Wood Gliding Club had a good
I'll be back again soon
11/Sep/12 - Genesis
Since the first flight of Neil's Genesis,
I have been trying to edit the video footage of its maiden flight.
However, a number of computer hardware problems has resulted in delays to updating
this website, and getting to grips with video editing. It's all
sorted now and I have uploaded the first video onto Youtube. Click on
the link below:
My initial upload was not particularly
good as youtube edited the film to stop the shakiness of the video such
is the nature of hand held videos trying to follow a quick model being
put through it's paces. The video had a weird effect, so I have now
removed it and added a few better videos.
A second video, slightly better footage
of the test flight and includes a number of still photos capturing the
story so far. Take a look for yourself
Last week, Neil and I attended the RAF
Model Aircraft Championships at RAF Honington in Suffolk. On the
Saturday Afternoon, we returned to Neil's place in Lincolnshire,
prepared our scale models and was up exceptionally early the next
Morning (5:00am), to drive the 3 1/2 hours to The Long Mynd in
Shropshire, to attend a Scale Competition.
We flew the ASH, Libelle and the Pilatus
B4, Yes I had managed to repair the Pilatus after the mid air at Leek
and Moorland a few weeks earlier. Aesthetically, you can't see that the
model has been repaired and it flies just as it always has, Great!
The Genesis model, turned a few heads
and was the subject of much debate, but sadly it did not fly as the
Aileron servo gears suffered some damage during a launch. This has now
been repaired and we await good conditions for our next outing.
I have been back in the
weasel workshop, between editing video, updating the website. I have
been sanding the Genesis
wings in readiness for the ailerons to be cut out and Spoilers to be
fitted. Now I have finished uploading videos, work on Genesis should now
pick up pace, and I hope that I will have it sorted in a few more weeks, I
Some more photos to come of the finished
model, when I get there and I hope more video of the maiden flight.
See you soon
23/Sep/12 - Genesis
Yesterday's weather was an exception,
cloudless sky, great visibility, but alas, no wind! pity, as it would
have been fantastic up on the hill. At least it gave me the opportunity
to get back in the workshop.
Work has recommenced on my Genesis. I have
now re-glassed the wings having sorted a few problems with my previous

covering and I await for this to cure properly so it can be rubbed down,

Genesis 2 test flight, which I hope to undertake before the weather
turns for the worst. Still much to do.
See you soon CW
I have not been getting out and doing much flying due to all this rainy
weather, it has allowed me to get back in the workshop
to progress my Genesis.
The wings have now been trimmed, and treat
to a couple of coats of sanding sealer and rubbed down. Also the
Ailerons have been cut out and the mating surfaces filled with epoxy and
micro balloons. Next is to install the Spoilers, the wing surfaces can

I must thank Curt Lewis in the States',
who has been really helpful. Curt
owns a full size Genesis and has provided me with some really good
information some excellent photos. In fact, he has many youtube videos
of his aircraft in action. The link below is of Curt in his Genesis
dumping water ballast on a fast flypast. Pretty cool!
Now that's food for thought..... How cool
would it be to fly across the slope and vent water ballast just like the
There's still a way to go on my project,
but once the canopy is fixed onto the frame and everything is checked
for alignment it'll be time to don the mask and start painting.
Back soon. CW
Pilot ready and waiting
for my lack of updates but progress has been slow.
Since my last update, I have been quite
busy at work trying to get ahead of the game so I could go away on
holiday. a couple of weeks ago I spent a really good week in Shropshire
with my partner at a really nice B&B in Church Stretton, one that we
visit quite often, being at the foot of a favourite range of hills
called The Long Mynd - Well worth a visit both from a flying point of
view and the fact that there are some fantastic walks and country side.
I just had to take a model, the walks we quite good too, we even spent
an afternoon exploring the Castle at Ludlow. We had a really good time
and the weather wasn't too bad either, allowing for a few hours flying
either early in the morning or when we got back from our outings, prior
to nightfall. One evening there was a really good sunset which coincided
with a westerly wind and a visit to "pole Cottage" the "Long Mynd's
Westerly slope - a really nice sun down flying session.
The following weekend, Neil and and Sue
came up to Lancashire -the girlies going out to find craft shops, such
are their interests, whilst Neil and
I spent two full days up in the
hills getting cold but having a really good time - plenty of lift. Glad
I took my sports shelter to hide from the icy
Eastlery wind though.
Genesis has been progressing, albeit at a slow pace. I haven't been able
to get much done during the evenings due to work commitments and the
weekends being taken up with other things, as well as making the most of
the conditions to go flying. However, there has been progression
none the less.
The cockpit (Seat, Instrument
panel) has now been finished including the joystick which is mounted on
a ball link allowing it to move. The Canopy took a good deal of time to
get right. Damaging the original transparency while I was trimming it,
so I had to cut and trim the spare.
Designing and getting the front canopy
hinge to work also took some time to get right. Many attempts has now
resulted in a plywood offset hinge and I/m glad to say works really well
so the canopy now hinges / tilts from the front, which sits nicely in
place with the Cockpit installed. The Spoilers have now been installed
and the stabiliser/tailplane assembly and linkage has been completed and
the incidence set with respect to the mainplane incidence.
that is left to do is cut the holes in the wing root of the fuselage to
accept the additional front locating pins and wing retention mechanism
and the holes for the wing control plugs. A final sand and tidy up of
the fuselage, hopefully this week and then it'll be ready for the paint
finish next weekend.
Whether I get to test fly the Genesis
before the turn of the year remains to be seen,
but if the weather Gods are on our side,
it may just happen. Lets keep our fingers crossed.
Hope to bring you an update next week.
25/Nov/12 - Genesis
starts to get its plumage
the additional construction work was finished during the evenings last
week. I wanted to start the painting on Saturday, but unfortunately I
had to work. So on Friday evening, I
ventured into the workshop to give the whole airframe a light dusting of
primer. This was done primarily to highlight any other blemished on the
airframe that I had missed and that would need filling.
On inspecting my handy work on
Saturday evening, it was evident that a few areas of the fuselage needed
a little filler mainly on the mould seam line due to a few air bubbles
in the Gel coat. On Sunday Morning, no, not an early start, but having
rubbed down the filler from the night before, I was soon in a position
to start applying Genesis's plumage. The fuselage was hung up and given a
number of coats of primer, checking after each coat, and the flying
surfaces also receiving a coat or two of primer.
on this evening, I managed to give the Fuselage a coat of Gloss paint.
she is starting to look really nice. The tail and rudder has also had a
coat of gloss. I don't normally use gloss, instead I opt for clear
lacquer on top of the primer, but Neil's model looked good having
received both primer and gloss, so I though I would give this a try
myself. It has come out really well, although when fully hardened I will
this gloss finish with 2000 grade wet and dry and give it a good polish to get a nice even high gloss finish.
The canopy frame has also had its paint;
so, short of a polish of the transparency, the canopy is all but done.
Tomorrow evening, I will be attending
the regular winter evening indoor flying session, so this will keep me
out of the workshop until Tuesday, when I should be able to progress the
paint job further.
Until the next update.....
the weather has been clear and sunny this weekend, there's been very
little wind, and it's been pretty cold. Indeed, the frost has not melted all
today, and there's snow on them there hills, and more is forecast.
However, that has allowed me get back in the workshop.
the evenings last week, I was busy painting the wings. The top coat
being applied yesterday, Saturday. After a leisurely breakfast this
morning, I turned up the heater in the workshop, but did not stay in the
workshop, far too cold initially. Instead, I put the computer to work,
to size, print and cut out the aircraft registration numbers and
ventured into the workshop at around 11am, the room had warmed up a
little by then. I started the job of flattening the paint on the
fuselage with rubbing
compound and polishing to a good gloss finish. Once this was
done I applied the lettering. I also installed the rudder and stabiliser
servos. The photos do not do it justice, but I am pretty please with the
outcome. The wings are still awaiting some attention and this will
be the activity for the coming evenings; the paint needs flattening and
polishing, Spoilers need to be painted inside, and the radio gear needs
the final components installing. I removed the Spoiler servos so the
wings could be painted, so these need to be reinstalled and the aileron
servos need to be installed completely. Ailerons will need to be
attached and then connected.
are looking good Neil and I have arranged a flying session on the 15th
December and hopefully, weather permitting of course, Genesis will take
to the air. That's the plan anyway.
So here's to a productive week of
evenings and hopefully all that will be left for next weekend will be to
programme the radio, and take a few photos.
See you soon
Work is progressing well. The wings have
been rubbed down and polished and the subject aircraft competition ID
markings applied. The spoilers have been painted, reinstalled
along with the associated servos, and checked for operation, although I
still need to sort out the servo covers for these.
I am now installing the aileron servos.
but this is taking a little time to get the servo mount right to
maintain the clearance for the servo arm and ensure that the servo
covers seat properly. Hopefully, these should be done by Friday evening.
Then I can make up the wing wire harness and get it installed.
I reckon by the end of the
weekend It will be finished. So lets hope this dreadful cold weather
clears ready for the test flight on the 15th, don't know the venue yet,
it all depends on the weather and wind direction. hopefully I will be
able to bring an update on the build in the next day or so, and then
hopefully get a few photos of the fully assembled model. Watch this
Friday 21/Dec/12 - All done
Almost to the day, during a post winter
solstice flying session with Neil last year, from when the idea of a ¼
scale Genesis 2 was conceived, I can now report that my Genesis 2
creation is ready for its test flight. I was hoping to get the model to
a flying condition last
where it could have been test
and although Neil came up to
Lancashire for a spot of flying, the wind direct and conditions were not
suitable. Saturday saw low cloud and rain showers throughout the day,
although we did go flying!..... Sunday whilst cold and bright, the winds
were very light an variable, Both days were west to South West which
would have made landing on the face of the hill somewhat tricky with a
New Scale Glider. Notwithstanding this, the model was not quite ready
The servos and wing wiring harness have now been installed and servos
covers fettled, painted and fitted. Last night I assembled the whole
airframe ensuring that the wing joiners, locating pins and plugs lined
up correctly. That done, I tweaked the Elevator and Rudder servo
installation prior to applying lead weight to the nose to balance the
aircraft and get the centre of gravity in the correct position. I still
have to fix the lead in place so it does not move during flight, and at
some time. I also need to fit the Aerotow release servo, but this
additional control can wait until after its first flight.
I weighed the whole model last night, my kitchen scales deciding not to
play as the model exceed its 5kg limit. So, armed with the bathroom
scales, I weighed the model which came out at a respectable 5.3kg
(11.5lb). I have not quite worked out the wing loading yet, but given
its generous proportions, I have no doubt that this will be well within
a respectable tolerance.
the weather forecast is not good for this coming weekend, more rain and
high winds I’m afraid. But hey, the model will get to fly as and when
the conditions are right, hopefully sometime over the next few weeks. I
have now finished work for the Christmas break and I hope that the
weather will at least allow me to take some photos of the complete
airframe. Watch this space for the photos.
This project has definitely been an adventure, a labour of love at times
but, I am more than happy with the outcome. Definitely well worth the
effort on looks alone. To say I’m really chuffed with the model would be
an understatement, especially that it is actually only the second large
scale glider I have built, the Pilatus B4 being the first from a kit,
but the Genesis 2 project was a whole new giant leap, to build from the
CAD drawings, make the Mould and experiment with different techniques to
acquire the desired outcome. Definitely a great experience, I just
I am really looking forward to getting
some air beneath its wings and putting it through its paces and to
report on the outcome with some more photos and video and it would be
really speciall if I could get video of both G2’s flying together,
however, this may be something for a later outing. For now, its one step
at a time. If it happens, I’ll bring you an update.
I would really like to thank Jim Marske (Designer) and Curt Lewis (Owner
, 95) for all their help along this journey, without which, Genesis 2
may not have been built. Thank you.
Here’s wishing you all a very Merry Christmas, and hope you have great
New Year with clear horizons and fantastic weather.
Ready to go
The weather cleared for a while today
although the wind was gusting 30mph, but I wanted to get the Genesis out
of the workshop and venture up to Jeffrey Hill for a photo shoot. The
wind direction was not suitable for this drive-to-the-top hill, and
given that it was about 15:30hrs with fading light, a maiden flight was
not expected, I just wanted to capture the complete model outdoors.
So as promised. Feast our eyes on
Even though I do say so myself, the
model looks great and it just looks and feels like it just wants to
fly......... I can't wait until the weather is suitable for its test
flight - Lets hope we get some good weather soon.
I'll bring you updates as soon as I
can. Hope you all have a really great Christmas.
- Forecast is Good
Happy New Year to you all.
Christmas for me was quiet, I even managed to stay out of
the workshop for Christmas Day, my partner and I went
out for the day and had a Christmas lunch / picnic - turkey sandwiches,
mince pies on top of "Gummers How" overlooking lake Windemere in the
Lake district. (wish I'd taken a model.)
We have been planning a Christmas
picnic for many years, but the
weather always got the better of us, but this year we were determined
regardless of the weather. As you can see, the cloud cleared for us
providing us with quite a dramatic view.
The Christmas weather has
not been conducive to flying, mostly low cloud and rain. However, the
forecast is good for the next few days, Neil is available, so we're off
to the Leek and Moorland SW flying site, this is just to the east of
the town of Leek in Staffordshire. The venue just happens to be equal distance for both of
us. Indeed, its where Neil's Genesis was test flown. So, Given the fact
that My genesis 2 is ready for its maiden flight, the weather is
forecast to be W / SW 9 mph possible gusts to 15 mph I think its time to
get some air beneath its wings; a promise of a pub lunch is also
appealing. I hope to bring you the photos and video, so stay tuned as
However, I've not been idly watching tv and getting bored, as you may have guessed, I have been in the
workshop. A new canopy and frame for the Pilatus B4, which was damage
earlier in the year, a new vac bagged wing for a new sporty flying wing
design under development (see Blog - 16 Aug for
photo and original plan form). The new wing is a tapered wing rather than
the original swept back design which I have made to compare the flying qualities.
And, I've got a present for Neil,
who on his last visit to Lancashire for a for pre-Christmas flying
session did show some interest in my Genesis 2 cockpit. So over the last few
days, I been creating a cockpit for him. And of course, Goofy just had to
test it out.........
The seat is primarily fabricated from
foam, glued to an 1/8" ply base. The foam is shaped on the band saw and
a 1/4" sliver removed for the seat cushion, which is subsequently
reduced in width by about 1/2" and stuck back on to the base and then
the whole assembly covered in two layers of 160g Twill weave glass cloth
and epoxy. I use Twill weave cloth as it moulds very well to intricate
shapes. The instrument pedestal is also made from 3 pieces of foam and
assembled before covering with obechi wood veneer then a layer of 49g
glass cloth. The instrument panel is a good quality photo behind a layer
of plastic (Margarine tub - well, one has to recycle!) with the
instrument holes cut out. the control column is made from a
plastic tube and carved car body filler for the hand grip, which is
mounted on a 2mm steel rod and is pivoted on a ball link allowing the
stick to move. It wouldn't take too much to get this to move with the
radio control, but not this time. Every time I make things like this, I
am on a learning curve, Neil's cockpit being in my opinion, better than
my own and uses slightly different techniques honed from the first
attempt. Indeed, this cockpit went together in just a couple of days -
most time was waiting for the epoxy to cure. Pretty convincing I think -
Hope Neil is pleased with his new cockpit, although I think Goofy will
have to wait.
Anyway, I'm off to get ready for
tomorrow, an early start to meet up at Leek for coffee and croissants at
9am, (well, one has to live well!) prior to some flying. Hopefully back
tomorrow with some photos.
Having got up really early, breakfast and
on the road for 7am, still dark, for the 2 hour drive to Leek and
Moorland, the weather gods were not looking kindly on myself and Neil.
When almost at the flying site, it was obvious that the hill was
shrouded in cloud. In fact, all the surrounding hills were in cloud, but
not to be put off, on arrival, I duly parked up at the chosen site and
awaited Neil's arrival. Indeed I was looking forward to the croissant
and coffee I had taken.
New year pleasantries out of the way,
we both settled down for our second breakfast of Croissants and fresh
coffee in my car out of the cold breeze and drizzly rain. We exchanged
Xmas stories and discussed what shiny things Santa had brought. Neil was
made up with his new cockpit and it almost fit his Genesis straight off.
It just needs an 1/8" of the base trimming and it'll be a perfect fit.
The weather was still not showing any
signs of easing and conversations led to what models we had brought
along for the days flying. For once, I had taken along more models than
he, 7:5.!!!! This is a major event as we always take a
number of models to cover differing weather conditions, but more often
than not, he seems to always pack in more than me. To give you an idea,
when we both went on holiday together down to Rhossili in Wales, on one
day whilst the girls were off sight seeing, were managed to pack 24
models into Neil's car and there was still room for the others that we
left in the cottage. Well, we have to be prepared for all eventualities.
(full Rhossili story link )
Anyway, I digress.
The weather did clear at about 11.30
and having donned our wet weather gear and boots, we ventured out on to
the moor top and launched our small flying wings (Wotsit and Weasel) to
check out the air. Not so much lift and no sooner had we launched we saw
a few other models also flying in the distance to our left. A quick
landing and back to the car to check out the other modellers and more
importantly, see what frequencies they were using. Good job as most were
on 35MHz which Neil was flying on although non of the frequencies
clashed. Not so much of a problem for me on this occasion as I was using
2.4GHz, which, due to the frequency hopping characteristics of the
radio, does not suffer from cross channel interference.
A group of locals had congregated
on an alternative flying site just a mile 1/2 mile down the ridge
catering for a more Westerly wind compared to the S Westerly direction
of our original slope. However, this slope was not really working too
well either, with the lift being very light, but all modellers together!
After an hours flying, we decided to have lunch - no not the pub lunch
that was discussed, as both our partners had packed up a suitable
selection of sandwiches and cakes. Oh the spoils of Christmas fayre....
after which, further flying ensued. The wind was now strengthening and
moving round to the S West. was it time to get the Genesis out?
After a while the locals started to
pack up and we decided to move back to the original slope with a view of
getting the Genesis ready for its first flight. This was not to be, as I
had noted on our walk back to the cars, that the neighbouring hill tops
were now shrouded in cloud. By the time we had transited the 1/2 mile to
the new site, we were also in cloud. A good strong wind, probably too
strong, but we could not see the track to the slope face, let alone the
horizon. More coffee and a thought that we could sit it out until the
cloud clearred, but to no avail, patience would not bring good weather
as the light was beginning to fade and no sign of the cloud lifting, so
the decision to go home was made.
Funny thing though, just 5 miles away
from the moor land there was light blue sky and light cloud, but this
only lasted until I reached the motorway and over the 90 mile journey
home the cloud base got lower and lower until there was no horizon and
So here we are, now awaiting a new day
for Genesis to make it's maiden flight, but patience is a virtue.
I'll let you know when it happens.
- Still Waiting
It's with frustration that I have to
report that the weather has not been good since the turn of the year.
Mostly Rain, but more recently snow, not that we couldn't get around but
the roads up to the local hills have been too hazardous to venture to
the flying site, therefore, Genesis has been kept in the workshop
awaiting flight trials.
Although the forecast has not been too
favourable, I found myself waking last Saturday morning to a totally
unexpected beautiful day, albeit very cold, it was a cloudless blue sky
and a Northerly 9mph wind, just right for Jeffery hill. But........ I
had planned other things so by the time I was ready to fly, the clouds
had rolled in and the wind dropped to but a slight breeze. Looking
at the forecast for Sunday, Low cloud, rain....... and yes, I'd missed
my opportunity. Indeed, low visibility (I couldn't see the hills) and
rain for most of the day.
Here we are, still awaiting a nice day
for Genesis maiden flight.
Life in the Workshop has not been void
of activity though. My new O/D flying wing sports model is almost finished.
The new trial 'lost foam' epoxy/glass
fuselage on the original "Wotsit"
highly swept back wing has now been mated to a new wing. The new design
is a more tapered wing planform and a new aerofoil section. This should
be ready this weekend for a test flight. If all is well with the new
wing, I will be cutting a new swept back wing with the new aerofoil
section and also a larger 60" tapered wing, all to mate to the new
fuselage. If this works out well, then I will be moulding the new fus
with hope that I may be able to sell a few.
Also on the building board is an
all new "Jart" aeros model
designed for high wind speeds. It
has a different wing section to the original to try and help improve the
slow speed manoeuvrability. this is well underway; the wings have been vac
bagged and I'm currently sorting out the tailplane. I hope to bring you
a few photos of this soon.........
I have planned to venture down to a
favourite range of hills in Shropshire (The Long Mynd) in a couple
of weeks, where I hope to meet up with Neil. So fingers crossed for good
weather. By then I hope to have quite a few models to test fly - Genesis
being one of them, in
readiness for the coming flying season.
I'll report again with more news soon.
- and still we wait
It may be Spring time, but it doesn't feel
like it. The recent clear weather has been cold, and now there is a
threat of more snow.....
A couple of weekends ago, my partner and I
met up with Neil and Sue at our favourite B&B in Church Stretton, at the
foot of The Long Mynd, having planned a couple of days flying while our
good ladies had planned to flex the credit cards and do some retail
therapy in nearby Shrewsbury.
The forecast had been ok
until the week prior to our visit, during which, the weather seemed to
be turning cold again; but you know what the weather forecasts are
like, sometimes they are correct, other times , not so.
Not wanting to be put
off by a little cold weather, we continued with our mission. We went
armed with various models for all conditions, but what was to greet us
on the Saturday morning was not quite what we had expected. With light and
variable N, NE winds; we tried the "Darnford" slope on
the North end of The Long Mynd, but the wind was not quite on to the
slope. So back in the cars and we ventured around to the NE - E slope
overlooking the reservoir. This slope was working better, but the lift
would come and go, sometimes the lift would be quite thermic, allowing
reasonable height gain, but it was very light and sporadic.
the weather was not right for flying the
Genesis, so it stayed in the car. However, whilst we predominantly flew
our foamy models, namely a brace of Weasels, which are great fun, I did get my new flying
wing out and gave it some air time.
Named Sharky due to the shape of the
fin - my new flying wing sport model initially presented me with pitch
instability with some pitch oscillations in level flight, but it was not
overly sensitive to pitch input.
The lack of lift made it impossible to
gain enough height to check out the centre of Gravity aerodynamically,
by abruptly diving the model and watching what happens to its flight
path without any pitch input, and I wasn't prepared to push the model
out too far over the valley - I didn't want to land out and go for a
walk, so I made a landing and added a little
more nose weight to see what difference it made.
The next flight was promising; the
pitch oscillations had stopped and the model maintained more speed, but I
was still unable to gain much height due to the conditions. Needless to
say, the new wing needs to be flown in better conditions to evaluate it
properly, but the early signs were good. It certainly looked good in the
By 1600 hrs we we both shivering,
indeed, the car temperature gauge said that the ambient temperature was -2 Degree C, with
the wind chill, I reckon it was actually about -5 Deg C, having drunk
all the coffee in our flasks, we headed
back for tea and medals and the warmth of the B&B.
Saturday evening, saw snow start to
fall (not forecast) and having enjoyed a good meal and a glass of wine
and telling ourselves that there is no such thing as bad weather just
the wrong clothing.....(we were prepared), we planned our
attack for Sunday.
Well, The snow continued to fall, and
by morning everything was covered in a light dusting of the white stuff.
Nothing too significant, but it had been freezing and with the forecast
a NE wind, it was back to the reservoir slope, but that plan was
dashed after we found the "Burway", the main route to the top of The Long Mynd closed due to snow and ice.
Not being put off, we ventured round to
the Northerly slope at Darnford, but whilst the red kites and other
birds were making the most of the light lift, it did not produce the
necessary lift to fly more than the small foamies, and of course, give my
new model another flight.
a Snow flurry passed through and
although we tried to keep flying we
couldn't see the horizon so we retired for coffee and the warmth of the
car. after the brief snow flurry the wind eased and shifted
round more to the East. So, forever the lift chasers, we ventured round
the back of the Mynd' to see if we could get to the reservoir slope.
road was open and we were soon donning our hats, ski goggles and gloves to try
again. The slope was not working, Neil launched and had a bit of a walk
to retrieve his model. I launched the Weasel and flew the opposite way
to Neil, but there was no lift there either. We kept trying for a while
but by 13.00hrs it was obvious that the day was not going to get any
better. Cold, with a temperature of -4
degrees C, the threat of more snow and no lift, we retreated to the warmth of the accommodation; after
warming cup of tea, we packed the cars and headed for our respective homes.
Funny enough , by the time we had
driven back the 110 miles to Lancashire, it was sunny, there had been no snow.
consoled myself with the fact that the wind direction had also been wrong for any
We'd had a good time though, and I have just received a
text from Neil saying that he is free for flying for the next 3 weeks,
so I'm keeping a close eye on the weather, although the coming weekend
is forecast to have more snow.
I hope to bring more news soon.
24 Apr 13
The Weather seems to be improving now,
and I'm plotting my strategy to get Genesis into the air.
Unfortunately, up till now, the only decent days with the wind in the
right direction on to the right slope has been midweek, so I'm to say
I'm a little frustrated is an under statement.
I have a couple of modelling away days
planned in May and June which are not too far away. I promise, as soon
as I have some news you will definitely hear about it.
11 Jun 13
I know, I know,.... I've not kept you
totally up to date, sorry for the lack of information.
I have been trying to get the lift
beneath Genesis wings but its either been too wet, wind not in the right
direction, or no wind at all. That said, I have not been sat idle
either. I ventured down to the RAFMAA 3 day Slope meeting back in early
May, again the weather was not quite suitable, but I did get some good
flying in; it was either very light and thermic or a howling gale. On
the day it was blowing somewhat, I aired my Jart and Dude Models,
perfect for the condition, I only had a few takers to have a go with the
Jart, but those that did, said it really grooved and gave the tranny
back reluctantly. I'm actually building another one of these, and its
now at the painting stage.
Having demonstrated the 60" Dude flying
wing, I have have secured orders for three fuselages which are now
complete and should be delivering these when I go away on a modelling
holiday...... Oops I let that one slip :-). Also, I've made 2 new plugs
ready for making the moulds, one for a new Dude Fuselage (with canopy
hatch), and another secret weapon..... small aerobatic model which is
the next model on from the "SmArt" model featured on one of my other web
pages... more news on this as it progresses.
Well, what of the Genesis?
No its not flown, but I plan to take it
on holiday where we'll be meeting up with Neil and his good lady for
another Model Flying expedition... I will come back to you with the news
very soon. I'm also getting married while away, so may well be a double
In the mean time, I suggest you look at
the new article - "Aerotow"
which shows that I have been out and about and have taken my first steps
into the realms of aero towing. What a fantastic weekend. Good weather
(no rain) and a very successful outcome to what seemed like a immense

Wind Beneath Her Wings
Its been a long time coming but Genesis
has finally flown…..
Last week my good lady and I had arranged
to meet up with our good friends, Neil and Sue at our favourite B&B in Church Stretton for a flying holiday.
The girls going off to visit craft fairs etc whilst the boys go flying.
In fact this holiday, was slightly different to our normal outings to
the Long Mynd. Indeed, although were at our normal B&B, we were
effectively house sitting whilst the owners had gone away on their own
holiday, leaving us with an extra bedroom to invite other like minded
friends, so three couple together.
The weather during the week turned out to
be quite light and variable. Saturday was good with a nice steady wind from the West
but not quite suitable for the Genesis test flight. Unfortunately the wind and conditions got lighter
and predominantly from the North East as the week progressed leaving us
chucking discuss launch gliders most of the time.
Wednesday was by far the brightest day with plenty of sunshine, but
still light winds from the
North East. However, there
was a little digression for Wednesday's activity as I had instructed my
flying buddies to
bring a suit and a shiny pair of shoes. Whilst we flew the light winds
in the morning, after a light lunch we all donned our best bib and
tucker and ventured to Ludlow so that my partner and I could get
married followed by a photo session around
Ludlow Castle, and then more photos
in the garden of our B&B accommodation. After a well earned
break...... a good cup of tea..... we were off to the hills again,
this time with the girls in tow for more photos
with Julie lining up the Pilatus for a wedding day launch....Yes
flying on my wedding day, Love is!
We got some funny looks from the many
walkers out and about that afternoon, and rightly so. Its not everyday
that you see a group of nutters dress up like they're going to a wedding
(we'd already been) running around the hills playing with toys.
At around 6pm, we packed up and went back to the
accommodation and made ready for the evening meal at a fantastic Tapas
bar called Housmanns. Well worth a visit if you go to Church Stretton!
Thursday was a bit of a wash out with low
cloud and rain, but we did manage a walk into the hills in the afternoon,
but no flying, although I did carry a model just in case.
Friday, however, was a completely different day. The wind
was back from the West, on the best slope, Pole cottage, Ideally suited
for for scale
gliders. The conditions started quite light, but by midday, the wind
had picked up with some nice sunny intervals creating good thermal
Having checked out the conditions with
various type of models we made the decision to get the pair of Genesis
2’s from the car and make ready for a test fly and fly them together.
After photos of the models together, Neil was first to take to the air
checking out the conditions with his Genesis, this time having
familiarised himself again with the flying characteristics he flew a
loop which was very impressive and nearly came unstuck when he executed
a stall turn close in to find that it tucked under in the vertical dive,
an indication that it is tail heavy. He did however, have plenty of
height to recover from the dive and flew around a little while longer
before making an excellent landing.
Having checked my centre of gravity which
was a little way in front of Neil's CoG position we lined up for the
launch. It took a couple of launch attempts; as with any flying wing,
the attitude at the point of launch is critical. However, on the third
attempt the model cruised away straight and level with no trim change..
With knees shaking I familiarised my self with the controls, and whilst
it didn’t create a major problem I noticed that the Spoilers were being
sucked out into the airflow by about 5mm. Obviously, the spoiler locking
mechanism needed slight adjustment. but the model was behaving very
well. Stalls we executed which were somewhat
benign in nature and the model just ate up the sky when put through its
paces. The CoG was checked out aerodynamically, and seemed to be spot on
with the model just slightly pulling out on its own from a fast dive. My
confidence was short lived though and what followed surely tested my
flying abilities to the full….
After about what seemed like about 10
minutes flying around, I noticed that the left hand spoiler had driven
fully out and could not be retracted. The model was slowing down and
sinking. Already low and ensuring that I always turned away from the stuck-out spoiler,
to avoid what could be a nasty tip stall and inability to recover, it
was hard to get to a landing position. I finally manage to line the
model up on the face of the slope and made an abrupt but safe landing…… On retrieving the model I noticed a strong smell of burnt
electrics coming from the open airbrake.
With shaking hands I poured a cup of
coffee and tried to analyse what had gone wrong by viewing the video and
photos that had been taken. I was please with the flight but really
concerned about the failure. With all the electrics disconnected, I
settle down to enjoy the remainder of Friday afternoon flying my other
models, there would beplenty of time to fault find when I got back into
the workshop. Following an excellent flying session at around 6pm, we headed back to our accommodation for
our last night of the holiday and to celebrate what I think was
generally a successful Genesis Test flight… the model flies well, but I
need to understand what caused the failure….… Party on!
Saturday Morning and after a thorough clean
up of the holiday accommodation, we left for our respective homes as our
modelling expedition and memorable events had come to an end.
Back in the workshop, I removed the cover
from the airbrake servo to find a molten mess that was once a servo…….
you can even see the heat damage to the servo bay.
I have analysed the problem that
caused the total failure of the left hand spoiler servo. In fact, whilst
the servos on the spoilers could have been of better quality and will be
replaced, to be fair, the problem was my own doing.
Having tried a few different receivers and
other servos it has become apparent that the 2.4GHz receiver was
programmed for High Speed operation. According to the instructions, this
mode of operation is not suitable for analogue servos. Guess what, the
spoiler servos and tow release servo are Analogue! All the primary
controls were driven by digital servos, so they were ok. The clue to
this was the constant buzzing from the analogue servos, not the one
fitted, these did not buzz at all. The alternative servos I used during
the fault analysis, something that
was not apparent when the model was initially set up. There is a
flashing LED on the receiver that indicates the mode, but unless you are
aware that the LED flashes at different rates and different receivers
give different indications then this is not readily apparent. The
problem was also apparent on one of my other receivers when switched to HS mode.
With the receiver suitable re-programmed
to normal mode, suitable for both digital and analogue servos, the
problem has been corrected.. No servo buzz and all the right indications
from the receiver LED. All my receivers have now bee
re-programmed, Lesson learned!
Please check that your receivers are set
for correct speed especially if you are using analogue servos, my
experience could have resulted in more than a melted servo; I was lucky.
Anyway, Replacement servos have been
ordered, and I'm in the process of replacing the wiring loom.
Additionally, I am looking at different methods of launching Genesis from
a hill, possibly by using a bungee, and of course there is also the
option of an aerotow at some time in the future.
Enjoy the photos. I hope to bring you the
