Some customers find that this helicopter always spin to one side no matter how to adjust it, this can be resolved by following the instructions below:
1. Switch on the transmitter, and put the throttle stick to the middle above or full open position.
(*This is the key point, DO NOT put the throttle to full close position like most of other helicopters, put to middle or higher position when switch on, so as the gyro can calibrate the center point easily.)
2. Lay the helicopter on a level ground, switch on the helicopter.
3. Keep it steady for 3-5 seconds for the helicopter to calibrate, when hear the light prompt sound from the helicopter, move the throttle down to full close position, now the helicopter is ready for fly, it will speed up when you pull up the throttle stick now.
In short, just make sure the radio throttle is on high position, and switch on transmitter first, then the helicopter, and wait several seconds for helicopter to calibrate before move down the throttle stick.
