I use mpro pixhawk with ardupilot firmware and Spektrum DX6 transmitter.
I have two issue with take-off at stabilized mode.
First, when it takes-off, it moves right slightly.
Trim of the roll is zero but it keep moving.
Second, it can’t control the throttle precisely.
It starts taking off when throttle signal is 16-18, and it’s speed it to fast.
I saw the doc that stabilized mode is set when throttle signal is 50, drone hover. And it takes its altitude and position autonomously.
But there are nothing correct with my drone.
