My spirit 2 is giving me following message in log after powering up:
Calibration Finished
Sensor Calibration is wrong
After that it's giving me good health message.
This error message pops up even after cycling power off / on and opening log again. Could this be related to crash, long time ago, where my Protos 380 fell about 20 m nose first to ground after main rotor got jammed by motor belt?

In a flight heli seems to be occasionally slightly jumping up and down or making other rapid blade sounds. Recently there has been few times where model almost tipped over on spool up, but after cycling power, it worked fine.
Full piro tictocs confuse rescue (this happened on my xl 550 with spirit pro as well). First rescue begins to tilt heli to left / nose first, then full left and eventually straight to ground. That's the point where I stopped training on those maneuvers.

Should I be concerned about the "sensor calibration is wrong" message and is there something I could do to fix it, as it's appearing on every boot up even without spooling up?
