I don't see any body indicating how to deal with the hinge gap. IE when I cut it out, then add the leading edge, trailing edge, if I use 1/4 balsa, then my aileron is now 1/2 inch longer than the trailing edge of the wing? What gets shortened to compensate for this, the wing? And how much, if I do it 1/2" then I stick my hinges in, and my aileron is still further from the wing trailing edge right? What am I missing?
