My mavic flew away on me yesterday I had 21 satellites then it switched to Atti mode and took off on its own I've copied the link for healthy drones

A recording of the playback of your flight would also be helpful, so we can see warnings and stick inputs throughout the flight. See: http://forum.dji.com/thread-82897-1-3.html (

Oddly the healthy drones link shows that GPS signal was good for the whole flight.

Were you able to recover the Mavic? It looks like it landed in someone's front yard.

It does appear to have landed/crashed in someones front yard... Now i'm not saying the two are related, but you may want to go talk to the person living there.

First of all you should be able to get it, it's under that tree, it looks like you lost gps at 2.03 and had also got IMU heading warning, but these logs from HD tell you very little you would learn a lot more if you upload your logs to http://www.phantomhelp.com/Phantom-4/#DataLog.

Did it respond when it went Atti mode
