Hi

 I would be grateful for some advice on the cause of a crash with what was previously a reliable home built quadcopter based around an apm 2.6 board as a flight controller.

The logs show that the fail safe was activated following a low RC signal which should have meant that it landed under control, however prior to this the logs show it veering away from the loaded waypoints so obviously something was wrong before that happened. It gained height rapidly and then dropped out of control without power from over 200 feet, in short i needed a carrier bag.

The battery indicator shows low on mission planner but a separate volt meter via frsky to Teranis radio showed normal voltage. I have never had unexplained incidents with this set up. If any one has a moment to look at the attached log and share any thoughts it would be much appreciated. 

Thanks Chris
