Since you're calling it circular, be sure it's not a small amount of TBE.
Sometimes the last, residual TBE has to be resolved with gain adjustments...
Man, I feel like a doofus. I didn't even think about calibration when I installed the compass. Duh. I hooked up the Naza and did the "IMU calibration" from the tools menu. The tool said it needed to be done so I did it. Is the IMU calibration the same thing as the compass calibration detailed on page 31-32 in the manual? Or do I need to do both?

And no, it doesn't hold well in a hover. And the circle that it performed during RTH was a pretty wide circle; maybe 10-15 feet diameter? I figured that's too wide to be TBE...

Thanks again guys.
