Disclaimer: my Air Camper is wood frame with fabric covering and cruise speed is 70MPH. That said, I can second what Mark L. wrote about rigging the ailerons with the trailing edge just a smidge low on both sides. My control cables aren't twangy tight but even if they were, the rigging trick would be worthwhile. The trailing edges of my ailerons ride about 3/16" low on the ground but quickly come up flush with the TE of the wing in cruise flight. Looks funny on the ground and your DAR or Tech Counselor will probably question it upon inspection, but once you get in the air and in level cruise, look out both sides and the TE of the ailerons will be nice and tight with the TE of the wings.
