The thought of wood screws holding your ailerons on in 1/4" wood, or even thicker for that matter, would scare me. When I had my first KR I had to replace my aileron hinges for some reason I no longer remember and I did all new screw holes and nut plates. It was fairly easy to add them to an already built wing. I just cut holes in the glass on the tops of the wings about an inch and a half by an inch to epoxy the nut plates to the aft of the spar. When I was done and made sure my threads were all good I stuffed little blocks of foam in the access holes I cut, sanded, and glassed on some small patches with two layers of glass to cover the holes. With a minimum amount of filler and sanding you could not tell that I cut the holes.

What's wrong with using wood screws on the aileron hinges? Just curious. I think it has been proven that they work on belly boards going 130 mph and they don't fall off. One think I can think of. The plans call for Nut plates and getting it past the DAR might be an issue. Being the ailerons are a primary flight control and the speed brake is not. Just a thought.

That is what I was thinking when I initially posted. I know that's a lot of force that bored going that fast.

Paul ViskBelleville ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I would not use screws for attachment. I used a piece of 1/4" foam to construct my belly board with glass wrap. I drilled multiple 1/8" holes in the hinge on the board side and used epoxy/flox and one overlay of glass to secure. I used a piece of 1/4" X 1 1/2" piece of pine from the lumber yard on the floor behind the rear spar and used five 3/16" bolts with "wood washers" to attach to the floor of the fuselage. 500 hours and 110+mph _______________________________________________ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.
