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 horizontal 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.
