I have recently moved to Ardupilot from Betaflight/ INav. I recently tried to test an X Frame F450 Quadcopter with Ardupilot. The Quadcopter was continuously spinning in the Yaw Axis, in other axes, it was very stable.

I have also uploaded the Flight Logs here- https://drive.google.com/file/d/1KPFudQ7eQdzuMOlSdfwVVneQxyKIj4ss/view?usp=sharing
I have a few Question related to the same-
-
Does it seem like a Calibration Error? I have tried to recalibrate the compass a few times and have also tried to change locations.
-
Is there some sensor gone wrong in the Flight Controller or GPS?
Thank You
