Solo PH 2.1 Green Cube AC 3.5 rc5

Working with the solo and moving it to master on the new hardware
had a hard time getting the compass to calibrate, so I changed the default to relaxed on onboard calibration
that fixed it so I could at least calibrate the compass
Did a short flight to check out vibes and got this issue on the quick review

Test: Compass = WARN - WARN: Large compass offset params (X:-309.31, Y:-177.16, Z:-91.35)

I know the orientation of the solo compass in leg is odd
and on the logs no bad health errors, everything looked good.

Is this just a solo oddity or should I ground this thing until I get it sorted
