Am I the only one having a problem with this quadcopter? It's pretty easy (and fun!) to fly but after the first five flights, the on-board controller failed and as soon as you throttled up, it would flip to the left. They sent me a new controller board after two weeks. It worked great for another 20 flights (no crashes) and now the throttle works but it ignores the joy sticks! Yes, I redid the binding but it made no difference. Called Hobbico again but the heli guy is never there and so far has not replied to any of the 6 or 7 messages I've left. Very frustrating! [:@]
