I have a Senior Kadet ARF with ailerons. Love it. It came with reduced dihedral...which you have done. We were surprised how little adverse yaw the Kadet ARF has in the ailerons. It turns quit nicely with just a little rudder. I have mixed some into the radio now, but initially had not. Mine has a Saito 72 4 stroke. It lumbers alont at 1/4 to 1/3 throttle. Hardly ever use full throttle except for show-off climbs. Landings are so slooooo wwwwww and soft!
