Bad compass health + error compass variance

Good time of the day.

I have a problem with compass, namely:

  • Bad compass health
  • Error compass variance

The error message pops up only after I arm and take off.
If my plane is on ground, there are no error messages.
What could be the problem ?
Plane 4.0.6

I will be grateful for your help. Best regards, Stas

What about sending in a binary log, to allow helpful people to see what is going on with your vehicle ?

I have no logs. I am using an external compass. but if I turn off the external compass I initially get a bad compass health error

LOG_DISARMED = 1 , and you get logs
