After painting my wings, my mechanic, (some years ago), installed the hinges on top of the wing. I immediately noticed a reduction in speed, but the real kicker was that the airplane would not climb above 6,000 feet, even with just me on board. I did some checking against other 'Coupes and corrected the position to under the T.E. and returned the plane to its previous performance. Since then I have noticed many 'Coupes with the hinges installed incorrectly and have tried to inform the owners, when I could locate them. It makes a BIG difference! Don, in Woodland, California
