its funny you say that, because back in the early 70's when my dad flew, he used .10 sized planes with NO ailerons, he says all you need is rudder/elevator/throttle.

I usually can land with no problem, but just not on the runway, usually very close to it though.... Still practicing. I have also taken Madd_Maxx's advice and started flying a tail dragger instead of the pt40. The plane actually is an underwing, and I can control it easier... due to no uplift from the trainers wings.
