RE: biplane aileron servo question
flaperons is the best way i think...allows better adjust if one of your control rods is too long or too shot without having to screw the bit about. with flaperons you can just trim it with the radio. i had a y harness and about 2 flights in i got rid of them and used flaperons - plus i get the benefit of flaps from the ailerons to slow the plane down quicker
