Hello,
I am another new owner of a Mavic Mini who has had the unfortunate misfortune of a flyaway. I have uploaded the flight logs to phantomhelp for viewing. |
The long straight line track of the drone is usually a clue that we're looking at a blow-away situation.
Your Mini was showing altitude instability and gaining and losing altitude without any joystick input.
For example at 3:59 you tried to descend, giving it full negative throttle, but the drone climbed about 40 feet.
From 5:05.6 to 5:13.8, it descended 70 feet without any joystick input.
Yours became worse during the flight and started and climbing/descending a lot.
From 6:00 to 6:32 it climbed from 208 ft to 468 ft without any joystick input.
Later things have gone out of control and the drone has climbed and climbed going to crazy heights, ignoring autodescent and climbing higher where the wind is much stronger than down at ground level and the drone has blown away.
At the end of the first part of the flight log the drone is >5000 ft up, >4000 ft away and being blown further at 20 mph.
It continued climbing, ending up at >8000 ft and being blown further at >25 mph when the data ends with the battery down to 4%.
Not long after, the battery will have failed and the drone fallen to earth further to the southeast.
I'll look a little deeper to see if I can find a reason for the uncontrolled climbing.
