the ar500 has a second ailon input /aux channel and all mixing you can need
The TX determines the mixing. I don't understand what you mean by that. I have some planes that use the AR500 for dual ailerons (independently as spoilerons), but I needed to assign the "gear" channel for ailerons. (easy for the JR 9303, but not all TX's allow assignable mating channels)
