I had a horizon tilt issue with my previous version of the P3 Pro firmware (1.3.20) and DJI Go App (iOS).   But after I upgraded to the new 1.4.10 version and calibrated the gimbal i have not been able to shake the horizon into a tilt.  Mine measured on a 27" monitor is 1/10th of an inch wider on left side of screen than on the right side of screen.  Before, I have had major tilt problems where I would have to take it up 200' site the horizon yaw and roll each way and then tilt the camera until the top edge would meat the horizon and it would have been off by a lot.  I would then have to pull up the gimble adjustment screen and adjust to the minus side (cannot remember now how much) but I think it was 6 clicks.
   If you upgraded to 1.4.10 and you still have the horizon problem but you have not re-calibrated, try this.  I have been monitoring mine and I cannot shake it enought to cause the problem now.

What is meant by shake? Fast, forceful, movements, or just yawing the aircraft? Just trying to understand. Are you saying 1.4.0010 corrected the problem in your case? I had the tilt using an earlier firmware version, but corrected it using a technique not related to firmware at all - it was a mechanical misalignment, not one of the voting buttons here..."Other" maybe?

Fast Roll and fast Yaw would always make my horizon tilt worse. On my previous version, I could not fix it with gimble calibration.  If I took it up high sighted the horizon and yawed or rolled at all I would get the drastic 6/10 of an inch tilt.  Now most of the time it is nearly 0 but every once in a while at the worst it is about 1/10  (measure on my 27" screen during playback) measure from one side to the other.  Darn, Yes I should have put other as a choice (too late now).
Thanks

Well, the good part is that yours is corrected now. That's great.

That's good news - not tested mine - been too busy - thanks for sharing.

Well from looking at the poll numbers it is only about 50% of us with new firmware that report better Horizon.  Hopefully yours will be better as well.

also, which type of horizon tilt are we talking about. the permanent tilt, or the one that comes and goes?

I guess  50% of us are talking about any kind of  horizon tilt issues as i don't care what kind they are as long as I don't have them anymore.  And I had it every time I flew before.  I was just hoping it was more than 50%.  So it was probably just the luck of the draw.

It still happens to me.

You can see it here, first scene:


I noticed that when I have the camera in an angle and I turn + tilt, when I let it go, the camera will still carry some of the tilt.

If the same happens in a windy day, there will be more tilt.

Yes, that is pretty much how mine would act.  But I have not seen it lately since this upgrade.  I was hoping it was gone for good.

Same issue with horizon after 1.4 update.

Same issue with horizon after 1.4 update.

Same here, even with offeset, seems better for a while then seems that the offset that before was necessary, need to be reverted to zero because is tilted on the other side.

when did 1.4.10 come out?  I dont see it on the download section...

I think they mean 1.4.0010 it has been out for about a month now.  some guys just call it 1.4.10 omitting the extra 00

here is a link for you

Also could you please change you user name for me. You are not allowed to have DJI in your user name unless you work for DJI.

Thanks

Yes, sorry it is 1.4.0010  (I must have multiplied by 100 lol).

I never had it until I upgraded.

I think from this experiment that the problem is like rolling dice.  Just because you don't have it does not mean that you won't the next time you fly or the next time you upgrade.  And from the responses it seems that more than half of us have the problem.

I just wanted to make sure we were all on the same page... hah

I recalibrated the gimbal from a flat/level surface and have never had a problem.  Check your anti vibration shocks to ensure the four are seated correctly and not damaged.

I have the very first DJI GO release.., and know exactly what Sir OP is mentioning. It's very annoying.Everything can be perfectly level.., but sometimes a fast movement left or right.., then stop still..., I will notice the horizon is not level.
Sometimes I can do a full 360 turn.., and come back to see the horizon is now level without adjusting the gimbal.

I have that problem after a few Cocktails

That's the way I should fly. Maybe it'll CORRECT my issue!

Corrects a lot of issues

The issue is still there along with the can't fly straight one.

It happens when you get strong winds side ways. It seems that the Phantom has a limitation side ways or double compensate.

The can't fly straight is really driving me crazy lately.   I take it up and forward and it goes up and forward / left and I stop and bring it back and do it again until if flies straight.  Why does it stop flying crooked after a bit?  Mine does anyway if I stop it when it happens and try again.  It is always when I take off and leave.

It actually doesn't stop.

It is just that you didn't trigger the issue again.
