Topic: "Too Much Angle Emergency" on startup
My drone worked great for 2 days. But today after I connect the battery, it started up then went immediately to emergency mode saying "Too Much Angle Emergency". I tried the flat trim button, restart, and reset but they didn't work.
It was on firmware 2.1.20. Tried upgrading to 2.2.3, the same problem.
I ended up with downgrading it to 2.1.16 and the drone worked fine.
Upgrading again to 2.1.20 and 2.2.3 gives the same result.
It doesn't to seem the gyroscope or compass issue as I could use it with 2.1.16, but more like a calibration problem.
Any idea to reset/fix?
