I am building by first big plane. The plane has a trainer flat bottom wing with strip ailerons. I can’t decide which would be better, to round or angle the leading edge on the ailerons. Concerned about gap for flutter in the ailerons. They will be controlled by a servo in each wing half. The plane will be a slow lazy flier doing the standard stunts, loops, wing overs, nothing fancy. The plane should weigh in at 12-14 lbs. 85" wing. I plan on a 26cc gas engine.
