Just had the weirdest thing. Took our plane (Nimbus 1800 VTOL) for a flight after a few weeks of no flying. Plane had flown fine the last time and hadn’t even been booted up since then.
Armed the plane to do a quick test hover, which was fine, then tried to disarm - and it would not!
Eventually was able to disarm with Mission Planner, tried to arm again and got an error that the trim values were lower than the minimum values.
So I checked, and all 16 channels trim values were set to a value of 874! The original values for all 16 channels was 1500.
How on earth does that happen? First time it’s booted in weeks and somehow all the trim values change?
Or is this just another idiosyncrasy of Ardupilot that we must accept?
