Drone Power Shut Off While On The Air

We would need to see the .bin log file - that will help a lot.

i had a switch from the batteries to the power distribution board which was “cheap” and couldnt take the load. from what it seems i was mostly flying with out heavy wind but when drone needed the extra power is were that power switch failed me.

Thank you for the response.
Please find it in the link below.

The log ended abruptly with the craft at ~140m so I suppose the Flight Controller lost power. I don’t see anything in the log to explain why. The Pitch,Roll and Yaw before the end looks just like other Waypoint transition events so nothing out of the ordinary.
You should have updated the firmware as there are some fixes for Cube Orange in later releases. I’m not suggesting that’s a cause of the crash just sound advice.
