I have a 50cc sized Extra 260 that has required quite a lot of up trim to fly straight and level. Balance is right on the suggested CG. Incidence on the wings and elevators is 0 degrees. When the engine is slowed to idle the plane tends to flare upwards.
I read on another site, that wing incidence should be +1 degree for an aerobatic plane to prevent too much up trim. My question is, since trying to adjust wing incidence on my plane would be difficult, could the ailerons be set slightly up or down to create the same effect? Not sure which way they would have to go.
