Been doing the plug for the fuel tanks ill make it from fibre glass, the intention is to make one big tank then carefully cut it ni half length ways, make a flat FG plate and lay each half on it and Hysol the tank to the plate then seal with FG
The tank as it stands is 300mm long 200mm wide and 130 high, hoping that will give me enough fuel for a reasonable flight time, as I think the two turbines at 44lbs thrust will be working hard to power this bird








The centre of the tank will be on the C/G

When I sheeted the wings I cut and pinned all the sheets in position then taped the joint took it off the wing laid it on the bench and ran diluted white glue in the joints, when dry I the gave the sheets a coat of resin on the inside and immediately glued it in place on the wing,

Laid mags on it to hold it down in place, im hoping the resin on the inside and glass cloth and resin on the outside will give it a stronger skin, I was originally going to skin it with pro skin the same as the Hunter but I think I like the wood better
This is about the only picture I took while away :)

I do like the idea of weighing down the sheeting with magazines - thanks for that, I'll store it away for future use! ;)

Yes it put pressure over the whole area, as little or as much as you want, just add mags, might be a bit heavy for you dinky ones :)
I recon the fuel tanks will hold around 7 lts of fuel so the should be enough for a few minutes,
Started glassing the wings at 2 this morning :( :S
Thanks: boz

I like the idea of pinning to the framework, then gluing the joints. You could in theory damp the wood so it forms to the foil shape at the same time. You end up with a pre-formed wing skin that won't put stresses on the rib structure.

Do it now, you may never get another chance

Hi Klipy I only pinned the sheets in place until I taped the joints then lifted it off and glued the joints
This I think has been the most difficult build I have done, so the next one I have decide will be a twin engine F104 in peanut scale,

If BB puts it down, he'll lose it! :P

if you are calm and collected when all about you are going berserk - you've missed something important!

IF I PUT IT DOWN I WILL LOSE IT :ohmy: :( :ohmy: Slander !!!!! my shed is a spotlessly clean dust free area where I know where every thing is :whistle: :whistle: :whistle:
Made a new canopy plug for it as the other one was not up to standard



And did the area at the wing roots, the first one I got the shape wrong

Got there in the end





Got the wings and part of the fuselage glass last night

Hi Tony
i think my p160 jetcat consumes 1 liter/min
i think it was over estimated, even so, it will mean that you have 2.30-3.00 mins flight time, that`s not a lot, unless that`s how long you guesstimated yourself

I think it will be ok, the SU27 I made an extra tank from F/G that held 1.7 lt the tanks that came with it held 3.6lt so that's 5,3lt
and I got a comfortable flight time of 7 minute with plenty to spare for go rounds, so if my calculations are correct, maybe not the tank will hold 7+lt, I think I read once that it uses about 420cc a minute, however much that is :S
