what size prop/engine were you useing? if you were useing a 60 i would recommend a 13x4, if a .75 a 14x4 and a .90 a 15x4. the key for trainers is slow flight, gives you plenty of time to react. i am guessing you had aa 12x6 or something similar which causes the plane to haul....not good when starting out. drop your prop size and keep the throttle low....should be much closer to realflight
