Hello

I've found a problem on my gimbal, when I "slide" on the right or the left, the gimbal is not capable to stay straight. So idk how to fix it now. Because the gimbal is calibrated and calibrated well.
So the picture 1 : when I slide on the right
Picture 2 : when I slide on the left
Picture 3 : when I stay in position, the gimbal is straight but it need +/- 10 secs to be fully straight
My drone has never crashed and is less than 2 months old.
The weather conditions: there was a moderate wind.
Do you think this is of software origin? Or hardware?
We can see that in both directions of the slide that the gimbal tends to be always lower on the right and therefore higher on the left which is a little strange...

Hi there, could you please move the stick gently while flying left and right to see if the issue still persists? And please also test it again in as windless an environment as possible. If the problem still exists, you can contact our support team via http://www.dji.com/support for further help.

You said you were flying in "moderate wind" condition, so I think you have your answer solve right there. As DJI Mindy point out, please try fly the aircraft again on windless day and I think you should see nice level horizon again and no further problem. With this little guy being so small and light, wind is always gonna create things such as crooked horizon. Happy flying and safe flight!

Okay ! I'll try without wind but in my country it's very to hard to have a wind arround 15 km/h (when I did my flight the wind was arround 25 km/h or 30 km/h I think ?)

At these wind speed it's hard to drone and gimbal to compensate wind gusts.

At those wind speeds you could lose your drone as it is not that powerful.

So I did another flight without wind this time and I can see that the gimbal is straight when I have a speed of less than 2 m/s. The horizon starts to be less straight from 3 or 4 m/s and there again it remains straighter than in strong wind conditions.
And there is also a phenomenon of inversion... That is to say that the highest side which is for example on the right, well if I increase the speed like 7 m/s or more, the highest side moves to the left. And again the horizon remains more or less straight.
So the wind affected the gimbal but it stay a little bit tilted.
Well, I still don't know what the problem is but I really hope it's not a problem of my drone... I was very careful the drone shows me no error
I already sent back a mini 1 because it had an imu problem :/ it would be very sad if I had to send back my mini 2 too...

Sounds like you are trying to push the mini too hard,   for better wind resistance and speed of gimbal you need a better drone with better wind resistance.

First, always check your Attitude Indicator.   People have made tons of videos on this topic so here's one of them:

To see if your drone is fighting against wind, hover your drone and don't move the sticks, check your Attitude Indicator while it's hovering steady.

If your drone (grey lines) on the AI is tilting heavily, that means it's fighting against wind very hard:



If your AI looks like any of these images, that it's either tilting heavily or rising/diving heavily, then you're in a very windy situation. Most gimbals on DJI consumer drones can only handle the wind speed of 8m/s before it shows tilts in images. So, if the wind speed exceeds 8m/s, even though you can still fly your drone and the video looks smooth, you might see this kind of tilting in your final image.

If your drone's indicator is perfectly in center and not tilted, then it means there's no wind affecting your drone right now. If your gimbal still tilts in this situation, you need to recalibrate your gimbal on the ground and contact DJI support if recalibrating cannot solve your problem.

The general rule is that where that grey bar is leaning towards, where the wind is coming from. The more it's off-center, the stronger the wind is.

Yes, but my last flight was without wind.
And the horizon is tilted when I slide right or left at a speed of 3 m/s and more...
I did a calibration surface at level. So I think it's good.
But I think it's not my mini 2 the problem because I see the same issue on YouTube videos like this one :
https://youtu.be/5KrDsgpim_M
At  1'45''.
His drone have exactly the same behavior that me.
(Hover position horizon is good)
Slide to the right (in the video) horizon is tilted.
I can verify on other videos but I already know two YouTubers who have this problem maybe more... So I think I'll keep it and avoid wind days x)
Pic : From the video on this pic, the drone do a slide to the right and like me, horizon is tilted.

I think you should check the attitude indicator at the real time to see if this happens. And make sure that you're not in Sport or FPV mode too.

You can upload your flight log to some place like drop box or google drive and share it with us.  That would help us find out the problem.

Okay. So basically, what you've seen on the forecast app was NOT ACCURATE.

The ground weather report provided by DarkSky and UAVForecast said that the windspeed is just 2.5m/s.

While the actual wind speed up above the sky once you've launched your drone, is generally 6-8m/s



So you're basically tricked by the forecasts and ground wind speeds to be thinking that there's no wind, while the actual wind speed is very close to the maximum wind resistance rating of your drone.

Actual wind data shows that your drone is flying in the avg wind speed of 6m/s with gusts of 7.7m/s. Mavic Mini 2 was rated to be able to resist the wind under 8.5-10.5m/s, which means the closer you come to this limit, the higher the risk that your gimbal might be restricted because of drone tilting to resist the wind.

This level of wind usually wouldn't affect your flying much but can affect your video and gimbal performance because when you're turning or moving your drone, it must tilt more than what was needed to just resist the wind. With that extra angle needed, the gimbal eventually would need to tilt a bit due to angle restrictions.

You can use cine mode to limit the tilt angle of your drone. Anything that limits the tilt angle shall help. And a little bit of tilting can be easily corrected with some post works.

Some tricks that you might need:
1. Switch to CINE mode, it limits the angular velocity of your drone, making it turning slower, causing much less tilting than normal mode.

2. Slow down your turning speed for CINE mode and Normal mode using DJI Fly app. There're settings available for that.

3. Extra slow down methods can be found here: . Helps to stabilize your drone too.

BTW your case is also the reason that I would like DJI to add estimated wind speed in their app's UI. Many times that people are fooled by weather forecasts or ground wind speeds and might blame things on the drone while the drone was actually doing fine. With a wind indicator we could have made much better decisions during flying!

As initial poster Arkglad has advised, almost certainly you are experiencing flying your little guy in too windy conditions which is causing the tilted horizon. Better to wait to fly when wind is around 2.5 m/s and these are the best conditions and then you will not have crooked horizon. Enjoy your flights and safe flying! Hope to hear all your problem solved when there is no wind.

try test flight your drone indoors / in a windless condition and simply hover it, then observe how the gimbal tilts when you turn your drone or turn the gimbal only (by touch and holding the screen for a few seconds until a virtual stick appears to let you turn the gimbal)

Weather, not just the forecast can fool you every easily. It can be calm or a light breeze at ground level but at 100m AGL it can be gusting to 40km/h.

Have experienced a incorrect weather forecast which predicted 20km/h wind speed with gusts at 35km/h at AGL but on the day the wind was just a light breeze at 5km/h with the odd gust at 10km/h but at 115m AGL the wind was strong enough for the wind warning to register on the drone. Sports mode will restrict the gimbal as well. Use Cine for video or photography and use sports mode if you have to fly into the wind (by remember sports mode and flying into the wind will drain the battery quicker).

I dare not indoors, wont it enter atti mode? but I will try it in calm conditions and see what happens, but we bought ours at the same time or there about, a few days in it and both from amazon, just weird how hi didn't do the tilt, we were about 6 ft from each other at the same height of which was about 10ft max, I will let ya know soon

Hardly any wind as seen by the indicator on the bottom left, you can see the tilt, I calibrated the camera and the imu prior to this flight. I would have thought that the gimbal could easily handle such a low wind speed, yet it still has a bit of lean.

My Davis anemometer is at 10m and showing 2 to 6mph wind speed, and dropped to zero when I posted this

I confirm. that sometimes my horizon is bent, but only from the wind. This is my fourth drone. The previous three curved even without wind. My advice: replace under warranty until you get a perfectly tuned one. The reason is the high tolerance of the components. I think so.

Less the wind is, less my horizon is tilted so I think it's the wind too...
And a YouTuber (french one) said that he have the problem like me (drone expert so I think like me he is really carefully about his mini 2). I think I'll wait for a new firmware because I don't want to send again and again my drone to dji (I try to limit my carbon footprint as much as possible about the the returns)
I know it may be silly considering the simple fact that I am a drone pilot ahah

When I look closer I can see that all your wires are connected
It's not our fault and yes, I have already seen a comment that said that rotating (yawing) right or left also corrects this not straight horizon and indeed it does. So I'm sure it has something to do with the wind because by yawing you change the orientation of the drone in relation to the wind and therefore the tilt of the drone! And in any case a lot of evidences go in the direction of the wind problem not taken into account...
As many people (who seem to know a lot) can say on this forum. Maybe your friend had been in a slightly different situation (the climate is complex anyway) I saw many videos on YouTube where the problem was noticeable but not commented by the youtubers surprisingly.

I am in the UK and it has to go to an authorised repair place, an Oympus shaver centre, what the hell is that all about lol
