Preparing for a maiden tomorrow, I experienced a terrain clamping 26 to 15 upon arm each time until I disabled the internal mag. Which I was going to do anyway but had forgotten. Subsequent arming after disabling the internal mag resulted in no more messages to that effect. I’m not sure if this is of use to anyone but thought I’d note it here anyway.
It is not recommended to use the internal compass as it can suffer lots of interference from the motors, it is always preferred to use an external compass above your motors plane.
Yeah I had just not turned it off yet and thought I’d post an experience if it helps anyone or the devs with any such issues.
