Horizontal calibration is required when the quadcopter drifts on the horizontal plane during flight. When this
happens, land the aircraft and disarm its motors.
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 wiggle the right stick left and right continuously until all
4 LEDs slowly flash yellow. Calibration is complete when all 4 LED indicators stop flashing. It is recommended
that users wait for 15-20 seconds after the calibration is completed before flying again. When using the horizon-
tal calibration, please ensure that the aircraft is on a completely flat surface. Do not move the aircraft or
calibrate on an uneven/tilted surface, or there will be errors.
If the aircraft drifts while rotating in flight, perform a rotation calibration. Hold the left stick up to the top of its
socket. Rapidly and continuously wiggle the right stick up and down until all 4 LEDs flash slowly. Make sure that
the quad is on a completely flat and smooth surface; place a small piece of paper under each foot. When all the
4 LED indicators flash in a clockwise pattern, slowly and smoothly rotate the X4 clockwise until all the LEDs turn
green. Keep the copter's feet on the surface and on the pieces of paper. The 4 LED indictors will again flash
clockwise; repeat step 2. If the quad requests a third rotation, restart the quad and start from step 1. Take care
not to lift or jolt the quad while calibrating it. Calibration is complete when the 4 LED indicators stop flashing.
Rapidly and continuously wiggle the
right stick left and right until all 4
LEDs flash yellow at the same time.
