Compass Calibration - Hubsan H501S X4 AIR User Manual

Compass Calibration

After the aircraft is powered on (and after a successful rebinding), the remote control /
transmitter will ask you to calibrate the aircraft compass. The remote-control screen will
first read "Calib compass 1", slowly rotate the aircraft on the horizontal plane. The LEDs
should be red, flashing clockwise. The remote-control screen will then transition to
"Calib compass 2", point the head of the aircraft downwards and rotate the aircraft in
place (it should be vertical, pointing perpendicular to the ground). The LEDs should be
flashing in vertical pairs, alternately. When the "Calib compass 2" disappears from the
screen and the LEDs begin to flash simultaneously, calibration is complete.
Rotate the X4 clockwise on
the horizontal plane until
"Calib compass 1"
disappears.
If GPS Hold or any of the GPS functions (ie Return to Home, Headless mode, Follow Me
mode, etc) are unstable, manually calibrate the compass by following the below
procedure.

left side of its socket.
