Flight Mode changing during flight...led to crash

[spanick]

Hi all,

I was flying the other day and everything was fine until about 10m into the flight when the P3A jsut started tumbling like crazy and I got the warning "Compass Error. Exit P-GPD Mode". I managed to (somehow) regain control of the drone and fly it back towards me when it happened again. This time, I could not regain control and because of obstacles between the drone and me, I chose to crash it in a field.

Looking at flight records on healthydrone I noticed that the flight mode was recorded as changed to Atti many times during the flight, but I never flipped the switch on my remote. Any ideas on what is going on here? I'm a new pilot and can't seem to diagnose the issue. Not sure if I somehow caused it or if my remote was/is glitchy or perhaps this is a normal part of some flights?

The drone changing to Atti mode means it is losing connection with GPS satellites.

Thanks.

After some more digging, I think I had an issue with the ESC or a motor or both. I'll be replacing them.
