Hello. This is my first attempt at manual PID tuning. My step response showed one overshoot and one undershoot before the line steadied out. I decreased P several times to at least remove the undershoot. It didnt want to go until eventually I got the result shown here - no oscillation at all but now the plot is drifting away from 1.
It's a Flywoo LR4 that I converted to Ardupilot.
