Trimming the accelerometer
Even after calibration of the Accelerometer, the QQ190™ might still not y perfectly
level in angle mode. If this is the case, you might have to trim the accelerometer.
Make sure that the radio trims are perfectly center- The trims on your radio should
not be used to trim the angle of the QQ190™. Instead, observe the direction of drift,
land, then use a stick input command to trim the accelerometer in the opposite
direction.
This means, if your QQ190™ is drifting left the
procedure is to; land, disarm and input the
accelerometer trim to the right using the
Trim ACC Right stick command.
You will see a red light blink on the Colibri, indicating that the trim is being registered.
One blink equates to about 5 units and these units are represented in Betaight on the
Accelerometer trim menu. You can adjust the Accelerometer trim values manually in
Betaight for further renement after ying. (gure 18)
