Denis, Daven says it all in the above
But now your stuck with a Gap and the best way to cover that is with some Glider Hinge Gap Tape. Its about 3/4" wide,,, half of which has that stick'em stuff on it and the other half is without. Just cut to size, peel the backing off and apply it to the wing,,, the clear half covers the gap and rides the FWD LE of the aileron.
There's also another way to do Skin Hinges, as per Dave Norman's instructions,,, there're posted over there at the
www.NMPRA.org site,,, check that out also
