Seagull Boomerang or Arising Star - any difference at all?
Concorde Speedbird replied to Jonathan M's topic in Trainer kits
I believe the wing section is a Clark Y on the Arising star, whereas like you have mentioned it is semi symmetrical on the Boomerang -
No issue, mine did this when running in. It will stop doing it after more running.

Sorry Mark, I have been tied up with work recently. Hoping to get back on this soon, I've done some more but not posted yet. I asked century jet to do the retracts like that to match the plan, and I believe they offer the electric conversion. They're pretty heavy, I might try to get lighter oleos at some point.

My granddad built one which I currently have, very nice aeroplane with a Saito 56. -

Wahey Initially when I placed it on the board I thought it was horribly twisted. Then I realised I had not factored in the fact that the wing was partially sheeted. Once I had, then I checked and it's probably the straightest wing I've built. Pleasing! Stiff now too. Next is to build the other half of the wing onto this half.

Making jigs to turn the wing over. And then turned over... And now glued. The mug row is on a bit of wood on the jig tabs to maintain straightness. I'm confident it will be straight when revealed. Next is either to do the other side of the wing or make the flap and aileron for this side, not decided yet.

Still lifting a bit at the front but more than good enough. Glued it now.

Bit more Front centre section done with the famous Mustang leading edge starting to exist As the designer specifies on the plan, the d-box is skinned from the outer retract rib to the tip, and then the wing is flipped over and the same done there. This stiffens the wing but leaves access to the aileron and flap areas. There's a great build on RCSB ('Mustang second time around' ) which I'm copying extensively, and he found this method worked as long as the wing is jigged when flipped to skin the other side. So I'm going to copy! I made up the skin... ...then wetted it and put it in position (no glue). I will leave it overnight, take the magazines off before work to let the wood dry fully and glue tomorrow night. Never bothered doing this before, but making an extra effort to improve quality with this (even rejected the first wing skin I made due to an unsmooth finish!)

Thanks all, and thanks for the advice Rodney. Cuban I agree, in many ways I find it a more elegant design than the Spitfire. Bellcrank for flap, I guess most would just use 2 servos nowadays. Working around the wing... Waiting for some centre section parts to dry, might get more done this evening.
