I have flown 20.9 h , distance 30.4KM , 213 flights, the drone was bought on December 13th
The main problem I see is that flying at night is horrible by default, you only see the blinking led and the problem is that if there is some wind, after 2 seconds the led changes radically the drone, in that aspect I think DJI would have given priority to the guide lights, maybe they sell them to put them to the MM but personally I prefer not to modify the drone.
Another aspect that I highlight is that the app DJI Fly needs a lot of improvement, currently the interface is very limited and it confuses the satellite numbers with what it shows in the image screen, there is important information that does not show, as the level of interference of the compass or adjust your way the % of the battery, if someone knows where I can make suggestions say it because I really want to suggest that to DJI.
Problems I've had:
1) I crashed it once for trying to do a quickshot and I thought touching the RTH button would cancel it but it didn't and I crashed it but I didn't damage anything.
2) The drone can't take almost anything in gusts of wind over 15 km/h, the most it can take is 20 km/h but apart from that, every time the "strong winds" warning is coming out and I feel that it's going to hit something.
3) Sometimes the drone descends a little bit without touching the control (someone said it here in these comments) and it's something that scares me sometimes if I'm flying in trees or poles.
4) There was a time when I was flying and out of nowhere the drone started to go out of nowhere (everything was well calibrated) and I quickly managed to return it but from there I am a little suspicious of this drone.
It has been a good drone for me, although I hope that they put a firmware where I record at 4K and manual mode in video, have new quickshots. Since the Fimi X8SE 2020 is the same price as the MM and it is a pity that the MM is very limited.
