I have a Great Planes Pitts 1/3 scale ARF with an O.S. 160 FX engine that have been flying for three times now, however it's very hard or almost impossible to make it turn right with aileron input only, i have to use rudder to make the turn. I suppose this is caused by engine torque, however I don't know if mixing some right rudder would be the best thing to do, Thanks!
