Hey guys, The PT-60 is a large, very stable trainer. Even with the lesser dihedral sport wing, it is not a great acro plane. It just isn't made for it. I had the exact same surprising no-aileron control on it's first flight. Just goes to prove you still need the rudder to fly. All I did is increase the control throws, by moving the linkage out on the servo wheel. Remember to keep the aileron differential in there to keep the amount of rudder needed to fly coordinated down. (Adverse Yaw) You still need it! This thing is still my most used airplane. So versitile. Skiis, floats, and sometimes wheels. I wouldn't mind putting in dual aileron servos, but I would also do flaps so it would be much more involved. Too bad Great Planes doesn't make a wing kit for it anymore. Since you already have the wing built, I would just fly it as is. Keep it in mind for your next project though. Keep flying.
