Horizontal Calibration; Taking Off And Landing - Hubsan H122D X4 STORM User Manual

3.3.2 Horizontal calibration

Horizontal calibration is required when the aircraft drifts on the horizontal plane during flight.
When this happens, land the aircraft and disarm its motors. Follow the below steps to do a
horizontal/gyro calibration.
1. Place the aircraft on a completely flat surface and then follow the below calibration procedure.
Hold the left stick to the right side of its socket. Rapidly and continuously wiggle the right stick left
and right until the rear red LEDS flash alternately.
2. Calibration is complete when the LED indicators stop flashing. It is recommended that users
wait for 15-20 seconds after the calibration is completed before flying again.
Hold the left stick to the right
side of its socket.
Before performing a Horizontal calibration, please make sure that all motors are
completely disarmed and that the aircraft is on a completely flat surface.
