The best answer is probably that the aileron is small enough in profile that you could draw it on paper, draw a second aileron overlapping the first with the correct downward travel and then measure the required gap. Don't forget that you will be wrapping the edges with glass to secure the aileron spar so account for the thickness of the glass also. I built my aileron 10 years ago so it would take some research to find just what gap I cut. I will mention again the one mistake I made on my ailerons. I installed the aileron spar with the aileron on a flat surface and forgot about the wing washout (twist). When I later installed the ailerons with the wing on the KR, the inboard and outboard edges did not line up with the wing trail edge. I had to cut the glass about 3/4 of the way on one surface of the aileron with the aileron in place, line up the trail edges and flox the spar again. When set, I removed the aileron and re-glassed the spar. If I were to do it again, I'd probably install the spar in the trail edge of the wing complete with blind nuts and glassed in place. I would then install the blind nuts on the aileron spar and just epoxy the skin to the spar on either the top or bottom surface, probably the top. I would mount the aileron to the wing with the wing on the aircraft, clamp the trail edge on the inboard and outboard end, then epoxy the other surface to the spar. When the epoxy set up, I'd remove the aileron and hinge and do the wrap with glass. Others may have a better method. Larry Flesner
