| Back to the Project X.....
I met a couple of good friends at our first indoor session of the winter season. Well, it's not quite winter yet but it is getting dark in the evenings
and the weather is bound to take a turn for the worst very soon.........
doesn't stop me getting out on the slopes at the weekends though. Although our indoor sessions
do give us a good excuse to get some mid week evening stick time.
Anyway, these guys had previously taken
a set of the Project X wing panels and assembled them, and have flown
them so much that they had worn them out. I might add that the closed
cell foam cores had only been covered in film on one model, the other
used to learn the skills of applying glass cloth and resin.. So I had cut
them another couple of sets of wing panels for the Project X and a
lump of foam to form the fuselage pod to replace their well used and now
ageing models. The end result speaks for itself
in the attached photo. Great looking model! I await the photo of the second model,
but this one looks good.
Given that I have also passed on a few
of my previous prototype models, this has led me to think of a few
options. I am considering taking the fuselage from the
X2 model design
and mating it with the Project X wing.
Mmm, watch this space ---. I'll make
one, once the X2 fuselage mould has been completed and I will report
I would share my vision for the Project X. Whilst I haven't finished
making the mould for the X2 fuselage yet, I wanted to see what it would
look like with this married up to a set of Project X wings. Given
a few minutes to cut a set of white foam cores and then offer up the
Fuselage plug, I think you'll get the idea of what I have in mind; and,
for what its worth, I now quite like the shape. Totally different to the
X2 and now quite pleasing to the eye.
So much to do..... this is yet another
model to progress, although I think I will keep this to foam veneered
wings rather than making it a fully moulded model. No time to waste, now
back to the workshop - I've got the X2 to progress and a set of foam
cores to veneer....... C U soon.
wings are now coming along nicely for the new model. I
have veneered the white foam cores
with obechi veneer and 1 layer of 25g glass cloth and epoxy resin and
Vac bagged overnight, and have glued a balsa leading edge and wing tip
which have been planed and sanded to shape.
It's amazing just how therapeutic a little balsa bashing can
be.......... and look at all the shavings......
The wing panels are very rigid and I am
quite please with the outcome, weighing in at 80g each. Once I have put
in the wire conduit for the wing servos, then these can be joined and
finished with another layer of 25g cloth. Then the Elevons can be cut
out and finished.
fuselage plug has now been mounted in readiness to start making the
mould, but we are a little way off from producing a fuselage, but I will
report back with the progress of this.
The fuselage mould is now nearing
competition. The two halves of the
mould have now been split open and the plug removed. I'm very please
with the outcome. The mould just needs trimming and polishing and it
will be ready to lay up the first fuselage.

I have also been progressing the wing for
the first to pair up with the new fuselage.
wing panels were joined having inlaid a plywood block to allow a decent
seat for the wing bolt which will pass through the wing into the
The whole wing has now been covered in a
layer of 25g cloth overlapped
around the panel join and epoxy resin. This is currently curing before
the Elevons and recess for the servos are cut out, hopefully in
the coming week.
I hope to lay up the first fuselage in a
week or so. so you never know, I may have a new model to test fly before
I'm making good headway on the new model.
The wing is nearing completion and almost ready for painting and servo
installation, I have just inserted the vac formed servo liners. The
first fuselage has also been moulded. It was a little fiddly to lay up
being so small, but the outcome is good. Over night in the airing
cupboard and the next day all was revealed. It looks a little untidy
when you first open the mould. the mess is essentiallya mix of excess
resin (swarf) and PVA release agent that will wash off in warm soapy
water. Once the fus is extracted and the swarf removed, the results are
good. This fuselage was done in clear resin so I could identify any
areas of the lay up that may give cause for concern but I am encouraged
that I got it right, making sure that I spent a little time laying up
glass tows into the sharp features - wing seat fin leading edge which
would normal cause problems before laying up the glass cloth.
The fuselage is strong especially given
that I have inlaid some foam in the fin to reduce flexibility. I will be
looking to paint the next one in the mould to see if I can get the
quality for an already painted fuselage, I have already prepped the
mould for the next one applying release agent in readiness.
Predominantly becalmed conditions has
meant I have not been flying much, although flying the X-1 on gummers
How in the Lakes on Christmas day was a blast. 40+ mph winds, the
conditions a little too wild for my Weasel model but the X-1 just needed
a couple of clicks of down elevator and the model just came alive, great
fun!.... the Festive picnic that followed with a view of Lake Windermere
was a great finale to a fantastic day out.. but I digress......
Progress of my current building projects
has been good. The Evolan fuselage plug has been mounted on to the
parting board and the first half of the mould has been completed. More
polishing now before progressing the second half of the mould. The X2
Wing plug parting board has been made and now mated to the wing Plug.
More polishing here too before starting the wing mould.
I have taken quite a considerable time
working out a number of colour schemes for the Project X and have been
quite uncertain which I
should chose as I like most of what I've come up
with. Decision made, and given I do not have a dedicated spray room I
have found the recent temperatures not conducive to painting, but I have
managed, albeit slowly, to progress the Project X.
I have completed the job now and the wing
servo mounts are already installed, so kitting the model out with radio
gear should not take more than a couple of hours and we'll be ready for
a maiden flight.
Hope you like the chosen colour scheme, I
think it suits the model and should stand out quite well. I will be back
with news of the test flight in due course.
It's the first weekend in Jan 17, and the
Project X along with my new Midge is now ready for its maiden flight.
The Radio installation is easy on this model, the wing servos are the
trickiest part due to the fact I have kept as much of the elevon pushrod
within the wing, but once these are in and the covers installed, then all
that is left is to put the battery, receiver and switch in the fuselage.
I initially installed an 800mAh batter but
this required nose weight to balance correctly. So, out with the small
battery and installed one of my many 2/3 AF 1600mAh batteries and a
standard receiver and the model balances perfectly without any
additional lead. The model weighs in at just a tad over 1lb (0.5
oz) (475g) giving a wing loading of 13oz/ ft Sq, which I'm really please
with. In fact this is less than the new Midge, but not a lightly loaded
as my prototype X-1 but this is a different model and I didn't build it
for light conditions.
This weekend had been wet with low cloud
and drizzly rain and very light winds. The forecast is better for mid
week with higher wind speeds predicted but as usual work gets in the
When It's had its first flights I will
certainly be coming back to let you know how it went.
Here we are and its mid April, and the
weather gods have finally seen fit to change the bias of good weather
from midweek to the weekends - Hurrah!!! and about time too!
Sorry, enough of the grouching, I have
now had the Project X out on the slopes and after a few sessions of
trimming I am now getting close to getting this model sorted. The model
penetrates well and is quite stable in pitch, roll rate is good but I
still need a to tweak the differential a bit more to get the rolls
Having flown the X from a number of
different slopes now the model does come alive in the presence of
increased compression on the front of the slope and on my local slope in
good winds its performance is pleasing. Today on quite a windy day up
on the Leek and Moorland site (LMMGA) the model felt clumsy. It
penetrated well, but with the wind speed gusting in excess of 25mph and
varying slightly in direction, did not present the model at its best,
and the wonky rolls certainly needs some attention or maybe I should
stop pulling in elevator when wanting to roll quickly, some more
exponential may also help here I think. This is still work in progress but I feel
that I am being a little over critical, as I want it to be just right
and it will be in time with a little more fettling.
I have also finished the X-1 model which, given only two outings this
week, is in danger of significantly overshadowing the project X, not
just in the way it looks but also in its amazing performance, the wind
on the Leek and Moorland site today presenting no problems for the
X-1 and I predict that this model that will be taking up a lot of my time over the
next few weeks. To find out more go to the
