Would be good if you could upload log files, there are members here who can tell you how strong the wind really was, or if it was something completely different...
Mavic Flight Log Retrieval and Analysis Guide
With the introduction of the Mavic Mini there has been a noticeable uptick in the number of posts requesting help with lost or crashed aircraft. While there is plenty of help and advice available on this forum, and detailed guidance and options on several other websites, I thought that perhaps a...mavicpilots.com
2 of them broke so I threw them away.I'd really like to see a side profile pictures of the propellers of this Mini. Were you using the prop. guard cage ?
I think you're in for a prop. change.

You can't avoid this phenomenon ... it's a design flaw which isn't fully understood nor is the reason proven yet. Your event is only one of many were the Mini can't sustain or reach pitch angles according to spec. due to that the rear motors are at max rpm's. I urge you to open a case with DJI to again make them aware of this ...2 of them broke so I threw them away.
No I was not using any extra payload.
What does cause prob damages? So I can avoid and be more careful from now on
I will upload pictures of my props shortly

Many experienced flyers are appalled to see reports like this coming in every day because DJI released a drone with two fatal design flaws.WOW.... I am appalled by what I am seeing
You should definitely stop sentencing DESIGN FLAW automatically every time. This is a case of propeller WARP problem...
... Your Mini isn't affected by a design flaw but by flattened propellers. I reckon it's almost a miracle it managed to fly normally before dropping.

I've never seen a single blade as warped as the one in picture 1 photo_2020-03-29_21-54-48 (2).jpg corresponding to the aft starboard side motor (RR). One of the aft port side photo_2020-03-29_21-54-45.jpg is showing a similar warpage, while the other matched blades of the (un)matched pair seem to be better.
The front shown in the 2nd picture photo_2020-03-29_21-54-49 (2).jpg it seems to me not as "fat" as it should be and not twisted upward enough. Small wonder this poor Mini plummeted to ground.
You MUST replace all your propellers before any additional flight. Your Mini isn't affected by a design flaw but by flattened propellers. I reckon it's almost a miracle it managed to fly normally before dropping.
Be careful here ... I think you may be letting an optical illusion push your opinion. The 'shape' of the prop blades shown in the four photos in post # 11 are correct and not warped at all. It is a strange angle to look at them in comparison to the usual top-down view that you see in advertising photo's - But - the blade is 'classic' in that it's showing a course pitch-angle at the hub end, and that reduces out to the tip. Also, take into consideration the angle of the fuselage of the MM as it is held for the photo. That shows the direction that we are looking across the blades. The way the blade changes its 'width' from hub to tip is also classic. Take a prop off your own Mavic and look at it from the same angles, I'm sure you'll see similar shapes ...WOW....

My thoughts too ... There have been so many 'new' drone users been caught out by them not realising that the wind-speed at ground level, is nothing like the wind-speed a few hundred feet up!I think the main problem was wind speed, from the log there seem to be a lot of high wind warnings. I have had a mavic 2 pro drone get carried away , when the wind at ground level was less 5 mph, when it got higher the gusts must have been 40mph at 100ft
Don't think all the wind warnings in the log event stream mean high winds in this case ... the AC haven't a anemometer installed, it out from other data make the assumption that wind is affecting it ... if that data is wrong or confusing like going max RPM's on rear but not reaching anything near the specified pitch that could be interpreted as strong winds. Note that the first wind warning already is triggered at 44sec with an height of 25 feet.I think the main problem was wind speed, from the log there seem to be a lot of high wind warnings.
