■ The motors do not spin freely after a crash.
Press the shaft down from the top of the propeller and motor to remove any objects, or
replace the motor.
■ One or more motors stop working.
1. Spin the propellers to see if it jammed the motors, make sure the propellers can spin
normally.
2. Resolder any broken motor connections.
3. Replace the motor.
■ The X4 always drifts to one direction.
Calibrate the accelerometer as follows:
1. Before calibrating the accelerometer, make sure that the propellers, motors and body
are in good condition with the battery fully charged. Ensure that the battery inserted into
the battery compartment correctly. Pair the X4 and transmitter, then put the X4 in Expert
Mode.
2. Put the X4 on a level surface.
3. Pull the Throttle stick fully down and move the Rudder stick to the lower right position.
Quickly move the Aileron stick to the left and right repeatedly until the LED lights blink,
indicating successful calibration. This calibration will reduce excessive drifting when doing
level yaw turns.
