Hello Barry
I analyzed logs and I did not find any errors. However, both logs suddenly interrupt. It is possible the drone has a problem with the power supply or there was a log writing error. As you understand, log writing error can’t lead to a crash. Actually, if there was a log writing error, you would see the error in the Ground Station.
I’ve also noticed that in the logs end the drone committed abrupt short-term incline. This maneuver could provoke a power failure if some wires were damaged, poorly fixed or connectors were worn out.
Have you been using Mission Planner while the drone crashed?
I think you might be on to something with the power. I am completely rebuilding the drone in an effort to sort that out.
What I did notice that in the Raspberyr pi POST there were a couple of “Low voltage” warnings when using the NAVIO2 power module. I will use a ubec on the servo rails as well to see if this goes away.
I use Qground control for my ground station. The only warning i got was NO IO heartbeat or something like that. I did not get any LOG errors.
I am perplexed by the sharp incline as the drone was hovering level. Might it not be that the sharp incline that you see is the beginning of the drone going out of control?
I was wondering if it is possible that the usb dongle I am using for wifi can draw to much power and cause and under voltage situation that can cause the unit to crash?
