F450 Issue, flew away, Genuine Pixhawk and 3DR GPS

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.
