Keep us posted. Never flip the transmitter off with the battery connected to the heli. That GUARANTEES the heli will go nuts. Always turn the transmitter on first, then attach the battery to the heli. Then, reverse the procedure after the flight. Disconnect the heli battery, then turn the transmitter off. My heli behaves perfectly... but if I turn the transmitter off first, it goes nuts. That part is normal. If the heli goes nuts after having turned on the transmitter first, then the heli, for sure check your batteries inyour transmitter. It seems as if your heli doesn't know the transmitter is on. That's either a problem with the transmitter, or the heli receiver. Neall
