roll axis autotuned. pitch and yaw not tuned yet.
as master leonard hall suggest
AUTOTUNE_MIN_D,0.0005 : selected
as advanced tuning wiki says lowerd
Your Z-axis vibe could be better as there is clipping shown on 2 axis. How have you mounted the PixRacer?
The pitch and roll tuning is not good. I suspect you will have to resort to manual tuning as I did on a mini-quad with a PixRacer. Also which compass are you using? The offsets are very high as they tend to be with one of the internal compass’s on the PixRacer.
Do you have foam over the Barn?
It’s input is quite noisy.
You have quite a bit of ringing on your Desired to actual roll and pitch
Maybe bring the _FLT values down a bit and reduce aggressiveness of tune and retune.
