Villa's right that originally, it was recommended that you score the wing at the spars to help with the bend, but that technique has been abandoned to keep the airfoil smooth and not put that flat spot at the top. The flutes do not run spanwise on the Debonair, they run chordwise. The flutes on the *ailerons* run spanwise.
Skerts, you can use any pieces of any plane anywhere, pretty much as long as you keep a certain ratio of wing to fuse to tailfeathers. You can read up on these ratios here: http://www.chrisspad.com/planes/main...paddesign.html
or you can just let it rock and roll and stick what you want where and try it out.
If it looks about right, do it. That's why I started using the Mr. Potato Head avatar on Spadworld because my flying buddies always took great amusement at me crashing a plane, and then the pieces showing up on another completely different plane. LOL Kinda the Mr. Potato Head of the R/C flying world. Let us know how your build goes and pics and videos are appreciated!
