hi，My drone has not been flying for a while. Recently, the test flight found that the drone kept nodding. By comparing the log, it was found that the despitch was lower than 0 as a whole.
Hello @moluav
you are posting in the trad heli forum. Maybe it would be better to post in the Copter forum, to get better and more answers?
