Doc, nice birdie..how did you attach the wings? You used the same method from spadtothebone? or you used your own method?

I devised my own spar for this build.
I had 2 pieces of aluminium "U" channel 20 inches each. Instead of using the wooden pieces in the middle I used aluminium channel. The main spar was 2 pieces of coro (I use Polycarbonate sheets) perpendicular to each other and stuck with 30 min epoxy. I first hen pecked the 2 sides that were to be stuck together. before I stuck then, I slit the piece with the flutes lengthwise, so that I could put the aluminium channel in between the 2 pieces of coro. I guess it is too confusing. I'll try and take a few pics and then maybe I'll be able to explain better. Just wait a couple of days and I'll tear open one wing that I had made earlier and then I'll take photos and post them.
