Short flight ended in violent crash.  Log analysis limited by short flight on Healthy Drones, but compass turn rates seem crazy.

Here is the link

Appreciate any input.  I don't *THINK* it was pilot error, because I really wasn't doing much.

Very little on those logs, except obvious compass problems, did you calibrate compass.

I assume you deliberately switched to Sport Mode?

Sorry to hear about your crash. I'd suggest you to send it in for further diagnosis and repair.
You could fill in an online repair request form and apply for pickup here.
You’ll get a case number automatically.

Already sent back to DJI - great customer service.  Analyzing the DAT file shows crazy YAW with no corresponding rudder input.  Zombie drone for sure.

It was actually my son's drone - I took the opportunity to buy my own.  Now we have 2 Mavics!
