UBSAN Q4 Instruction Manual page 15

(1) Before calibration the accelerometer, make sure that the propellers, motors and body are
in good condition with the battery fully charged.
(2) Pair the Q4 and transmitter, then hold the Throttle stick to the left and right repeatedly
until the two headlights blink, indicating successful calibration. This calibration will reduce
excessive drifting when doing level yaw turns.
(3) If the Q4 still drift to one side, set it on a level surface then add a few sheets of paper (the
number of sheets will vary depending on the amount of drift) to the side of the Q4 that
drifts. The paper will help counterbalance and create a level o set angle.
