Just posting this to maybe help others. My mavics been flying fine today out side in the colder weather. But in the house I had it running doing some thing with the props off. Gimbal calibration and such. It keep shutting off. Well I picked it up and it seem hot. Then I realized I didn't hear the fan running. Well I did crash it last week end twice into 2 trees. (bad day, lol) Turned out that a stick or something poked through the grate and into the screen mesh in front of the fan and bent it enough to jam the fan. I took the top off and was able to push the screen mesh back away with a toothpick. Its working fine now. But I wonder what would of happen if it was hot and 90 degrees f? Would what ever it was shutting it down do it in mid air? I'm guessing a sensor was doing it but I wasn't getting any error on the controller saying it was hot. I'm not sure what it would do. So I would suggest to listen for your fan often especially after a crash.
