Hi All,

Need your help to understand what happened.

Here is the LOG file.

Briefly, it flew away with almost max power.

Is it compas related?
I don’t like the accelerometer data just before it flew away… Looks like high vibration.

Using a Genuine Pixhawk and a genuine 3DR GPS.
V1.5.5 Stable

Did you by chance recently change any of the gain parameters?
I did that once and it seemed fine, then some condition came up and the parameters “blew up”.
At least that’s my theory.
