With gimbal calibrated and perfectly flat while hovering, it will tilt slightly when flying sideways, in the direction you fly. Then when fly back the other direction, it tilits slightly toward that direction, then when stop and hover agin, it back to flat.

Maybe you have it set in FPV mode?

i KNEW someone was going to say that lmao!!

No it wasn't, never was! I tried that feature once on Phantom 4 first day just to see how it looked, but not again since on the Phantom 4 or Mavic have I used this setting.

And that was full throttle, if the FPV mode was wrong, the tilt would have been MUCH more DRASTIC!

Maybe I should upload more of that video and might be more clear that was not FPV as that is a very distinct effect!


I do appreciate the input thought!!

That's why I started my sentence with "Maybe"

Yeah get that too. Full recal does help a bit, make sure your level at the start.

Actually have so much footage of the problem here. I'll slap together and upload a clip right now. I just accept it cause seen no other mavic video that's any better. Guys who claim to have a perfect gimbal through a whole run, let's see the video! I don't know if it tilts as badly as yours though, encoding a vid. Try full recal with a bubble level. IMU needs to be done before the internal fan on the ac kicks on. Other than that, it's just the way it is.

I've recalibrate everything a million times!! IMU, Compass, Gimbal!

Also, I always make sure is straight once in the air before I go.

Phantom 4 at times have started straight and ended a bit tilted, so you are right, none are perfect. Phantom 4 doesn't have this exact effect that i've noticed though.

I am also willing to accept coldness as a possible factor, although that clip was from the warmest day we've had here in weeks, and was above 0 degrees!

Also willing to accept is part of other more serious gimbal issues. (other post, working on video for those issues now)

Would like to see your examples as well

You can see, it starts off fine. But by the end of the same flight it loses it's way for some reason. You can correct it by holding c2+exposure dial up and down but it messes with the ev. It's almost like the mavic does a gyro level match on startup then doesn't bother to check it again. Wind comes along and the math now doesn't work. Like it's not a real time measurement of the gyro?

It looks the same on my P4. It's "normal" for P4 and Mavic unfortunately.

Nice video!

I see what you're saying!

I will recheck effect on my Phantom, maybe is normal.

Seems strange that would be the normal effect, gimbal is so effective otherwise, that a slight tilt going sideways would not happen.

The best look I've gotten at a DJI gimbal in action is the OSMO Mobile, and this doesn't seem to have that kind of issue..

Either way not the end of the world!!

That video was on .400 firmware.

And gimbal is fine when flying (except of course for random "flipping out" lol)

Please test more, and if the horizon tilts issue persists, I'd suggest you to send it in for further evaluation.

That seems a little overkill for that kind of thing doesn't it lol?

The gimbal moves fine all around, focus fine, it seems like maybe something in the gimbal algorithm, or maybe is just the way they work.

Went back through some other Phantom 4 footage and there are examples there where it tilted sometimes as well..

Mine has been doing the same thing.  Contacted DJI support and got the usual, "reset IMU, compass, gimbal, etc."  I actually thought I was finally going to have success this last reset, but after around 5 minutes of flying, the gimbal was tilted again to a slight angle.  Even doing the "adjust gimbal roll," it works for maybe 30 seconds to a minute before needing to be adjusted again.  

With all that, I've also noticed recently that my exposure needs to constantly be adjusted.  Thinking it's time to send it in and cross my fingers I get it back in time for my next trip!

That was their answer for me for any issue lol (of course those things are still good to try lol)


I am curious, what is the temperature where you fly on average?

Gimbal issues seem to be related to cold mostly, at least thats ONLY time for me, and i've seen other reports where it was cold when happened to them.

Plus some others who have NEVER had a problem have reported NOT being in really cold area.

And also in 1.03.0200, half that update was to address gimbal performance in cold lol (which funny for me it was the first flight after that update my gimbal when crazy and couldn't even shoot a video lol)

Anyway, with the now 3 distinct gimbal issues, I've personally only seen them happen when out in the cold!

Interesting note on the cold... I'm in Northern California and the average temperature I've been flying in has been between 40°-50°, with one of my flights being down around 25° (which actually had the least gimbal issues - go figure!).  

Maybe I'll hold on and try it out this week with the temperatures getting up past the 60° mark.

Try turning off the "Enable Synchronized Gimbal Pan Follow" under the 'Advanced Settings" in the "Gimbal Settings". I think that will solve most of your issues.

Very interesting!!

I thought (guessed) that was the part that helped making left to right pan more consistent, even if Mavic itself was fluctuating in the wind.. (regardless that is one of my favorite difference in Mavic over Phantom).

I will try it and see..

I did do one other test like that and effect didn't seem as drastic as first time. It was warmer but also background wasn't as distinct so probably harder to notice.

It's not the end of the world anyway, unless the back and forth motion is in a continuous clip it doesn't stand out too much, plus easy to rotate clip in post (but obviously less processing is always better),

Thanks for the suggestion!

i have the same issues .  i tried everything and ended up sending it back in. i made a few  videos showing my issues. i will link to them for you.

i turned off everything i could and reset everything for close to a month as i was out of town while i waited for my return label . i hoped it would fix before i got home and i would not have to send it it.

i sent it in yesterday though.

I have the same issue sometines when flying sideways .. latest Firmware by today and gimbal calibrated with the mavic Standing on a leveled Surface ..

No fpv Mode.. no issues when flying Forward or just rotating mavic when hovering.

Horizon tilt issue is still present on the new firmware .500. Also I dont see anybody on this forum mentioning anything about the Gimbal Pan Synchronous Follow. IT DOESN'T MAKE ANY DIFFERENCE WHILE THE MAVIC IS FLYING! The only difference is when the Mavic is turned on sitting on the ground and you yaw then you can see the camera moving, but this doesn't have any effect while in flight! Im a bit upset about not having any info on this.

Mavic Gimbal Issue

The imu was done right but the compass, want to point it strait down on the second part and get it away from the deck or anything metal. You didn't do a gimbal calibration either. Look at your yaw setting for the other issue

I have done the compass calibration with the quad pointing down as well. This didnt make a difference either. What do you mean the yaw settings? What should I take a look at.

If anyone has an unedited video of their Mavic flying sideways and not tilting the horizon, please post it. I would like to see it.

Do the gimbal auto calibration? Yaw settings are in there. I don't have the updated app so I couldn't tell you where in 4, but it's in there.

I have done the gimbal auto calibration as well. Away from metals or magnets and in a level surface which was checked with a bubble level. The horizon is very straight when the craft is hovering, flying forward or backwards. The tilt comes when is flown sideways.

Yaw settings I have playing with a lot as well. I just thought you had another suggestion

That's about it then. The readings on your imu should be very low when warmed up. If that's the case, maybe it's hardware. I know like gyro2 on mine is always a bit high (hangs around .005). The best seen it is .002 but it soon went back after flights. The rest both accel, gyro1 stays 0 to .001

So you have no issues with tilting horizon when flying sideways? Do you mind posting a quick video?
