I often put the ailerons into "flaperon" programming, assigned to a dial, with flap function at 10% or less so I can trim in the ailerons in flight.
Yeah I've tried those flapperons in several of my models. Could just be me but never much cared for them. Imho, true flaps work better than flapperons.
