Hello dear forum users!
I have a Mavic Pro Platinum and it has crashed three times already with roughly the same situation.I start the motors, the drone rises 4-5 meters, motors turn off by themselves, and the drone falls flat.
Please help me figure out the reason for the crash.

Here is a link to the log file of last crash (remove spaces)
app. airdata. com/share/RlSNYV

Before that there were two more falls:
6.05.22 (second)
app. airdata. com/share/KxAaZt
After this crash, the drone showed an error - "Downward vision calibration error. Precision Hovering and Landing Protection may fall"
I did the calibration on the front and bottom optical sensors and the error is gone.
No more damage


22.08.21 (first time)
app. airdata. com/share/BQWmPt


And just in case, I send a link to a normal flight, which was without errors
app. airdata. com/share/PCLPHb

Thanks in advance for any help)

HI,

Had a look at your last crash flight ; your barometric height at start is zero (normal) but after takeoff remains zero, wich is not normal!
Same for the vertical speed, zero all the time.

Calibrate your IMU for this issue. (nothing more you can do actually), check fly again.
cheers

Thanks a lot!
After the second fall, I did an IMU diagnostic. But despite this, there was a third fall a week later, probably the problem cannot be solved by diagnostics.
Today I handed over the drone for repair to the official service, they will change the barometer, which is located on the GPS board.

Hello everyone!
Drone returned from repair today. No defects were found. They said it was a coincidence. I hope this doesn't happen again
Perhaps the reason was in the firmware, because I used the SuperPatcher to remove the height limit.
Now I have updated official firmware

Hello everyone!
Has someone faced such errors when using a SuperPatcher?
