Hello!
Having flown a few times with FW 3.1.5 and it went well. Then suddenly it’s something that bothers.
Flying fine some minutes flawlessly, then something happens. Has happened 2 times with crach as a result.
Not the same place geographically.
Flying in Stabilize mode at the time.
Something happens to the compass?
Grateful for ideas.
Your graph shows a pretty normal level of compass noise. If you were to do compassmot, you might be able to get it a bit better.
Crashes in stabilize are generally issues with the props, prop adapters, motors, motor wires, ESCs, power or signal wires. I’ll take a look at your log if you post it.
