Yep ... this was another of the dreaded "Uncommanded descent" cases that the
Mini 1 is so famous for ... this originate from deformed props (usually the rear ones) not able to create enough thrust. This makes the motors spin faster to make up for the lost thrust ... that in turn generates all those hundreds of errors as per below you got already from 33sec into the flight, one of the messages clearly says what's going on ...
(Click on pictures & charts to make them larger)
This also generates a very bad AC pitch ... leading to heading speeds below what's specified, this is also seen during this flight.
When the thrust becomes even lower the motors eventually reach their max rpm's ... from there it's game over. The AC don't react to forward flight commands any longer, as seen here in the last seconds of flight when the AC goes backwards even though you command full right stick forward. At this point the AC is also losing height fast ...
Here a chart that shows the uncommanded descent ...
The blue is height from HP
The orange is vertical speed (positive values is descent)
The grey is you throttle stick (left stick forward/backwards) value 1024 is neutral
As seen in the last half of the chart... you applied several full ascend commands but the vertical speed stays positive for descending & the AC lose height with 4-5mph.
It's really surprising that you didn't react to all error messages at all ... they started to pour in already from 33sec into the flight ... but you kept on flying?
In the past when the
Mini 1 was newly released this was very common & DJI took responsibility for them back then ... don't have a clue how they will act in your case. With all these error messages this is border lining to a pilot error.
