I have a Pixhawked S1000 that I am tuning up. I did the autotune on the roll axis and copied these values to pitch. This helped quite a bit and it flies pretty well, not as nicely as with the DJI A2 controller, but well enough.
Then I autotuned yaw and the resulting values were startlingly high compared the to the defaults. The yaw is more responsive now but it has a tendency to keep yawing after I release the stick. Oftentimes it will continue to yaw another 90 degrees or so before stopping.
PID values after autotuning:
