• Attention:
• Compass Calibration
IMPORTANT: Make sure the motors are locked before calibration (left indicator is NOT flashing). Factory default setting, is for the motors to be locked after the completed ID binding process. (For details on motor lock and unlock process see point 7 and 8)
After calibration, first time taking off, the aircraft may drift in the sky, please just ignore that, and meantime the system will do compass calibration automatically. After 3-5 minutes flight, please land the quadcopter on the ground and hold the motor in order to save calibration parameter.
