    Prior to updating my firmware on 10/25/2017, by horizon was always perfectly level. After updating to 2.0.12 on Wednesday, I've had an issue in which the horizon tilts to varying degrees with yaw as captured in this video:



    As the video begins, I'm part way through the flight, and in the process of panning vertically to 19º to align the horizon with one of the segment lines. The horizon is already tilted noticeably, which is carried over from a previous yaw. Notice as I rotate the aircraft in yaw, the horizon tilts to an unacceptable degree. At various points in the video, the horizon does return briefly to level, but the degree and direction of the horizon tilt varies depending on the speed and direction of yaw. It is also evident on the video that some "dip" is occurring as well - the horizon is rising as the aircraft is yawed, despite the vertical pan remaining consistent at 19º. Also note that the various other parameters are being kept consistent as well - altitude, hover position, camera vertical tilt, etc.
    Although I don’t show it in the video, the aircraft is always set on “Stability mode” as opposed to “FPV”. I’m using Starlink version 2.0.3.20, which I believe is the most current version for my Android device (Samsung Tab A).

    I've contacted Autel customer support today with the details and video. I'll update the thread as I work with Autel toward a resolution. They were very responsive as always - I called at exactly 3pm eastern, needed to leave a message, but had a call back by 4:10pm eastern. Can't beat that with a stick!

    By way of comparison, here is a brief yaw shot from my XSP prior to the firmware update:

    Bummer..... That's clearly not right. Please post the results of your contact with Autel. The adjustment in the system will NOT fix that problem. :(

    I too had this same exact problem. Richard is spot on, contact Autel. The only thing that fixed it was when Autel exchanged my camera/gimbal unit.

    As an update, I've been in contact with Autel Support over the last week in an attempt to address the horizon tilt issue. Unfortunately the end result is that this issue is, indeed, a known issue with the new firmware official release, and Autel is working on a solution for a future release. I guess it's good news from the standpoint that I won't need to shell out a few hundred dollars for a new camera/gimbal since I'm out of warranty, but very bad news from a useage standpoint. Professional use for video is no longer an option with the varying degree of tilt present - it's actually a worse problem to have than the poor yaw control. I could work around the yaw control on the old firmware by planning simpler shot progressions for videos, and still images weren't really affected. Now video is out of the question - with the changing tilt angle, it'll be almost impossible and too time consuming to edit out. And still images require a higher workload to fix the varying horizon tilt for each image, not to mention the image loss generated by the need to crop the image.

    Anyway, here is a run down of my email exchange with Autel support (I had a battery issue as well) for those who are interested (all email addresses have been altered from original and all names redacted to protect privacy). One of my emails contains a link to another YouTube video that shows the suggested fix giving very limited, if any, improvement. The final email in the list is the one that confirms the issue is firmware related:

    Ugh...that's terrible. :-( They should be rushing you a refurb unit so you can get back to work.

    On the plus side, nice logo...we must have the same designer. :)

    Thanks for sharing your experience, that really sucks...

    Temporary solution: Buy one of those refurb units and sell when they fix the firmware? Could be a long time your $$ is tied up but might be worth saving hours of editing time and frustration on paid work.

    That is horrible customer service. No excuse. Upsets me just to read it.

    Autel better turn this around in the very near future. Eventually every one of us will be contacting them with some variation of this issue. If their current business model is displayed in this instance they have serious problems. Total bummer.......

    Great minds think alike, eh? ;) I actually used a "crowd source" type of design service last year to create the logo, after having pitiful luck putting one together myself. I take good pictures, but ask me create anything from scratch and results can be...underwhelming! Anyways, I ended up with about 60 designs - many of them weren't any better than my own results, but about half a dozen I really liked. My favorite was actually a different design, but when I asked the opinions of friends, family, and even several clients, this one was the almost unanimous choice - so what do I know!

    No problem brian bwin. I figured it was important to share the experience and the fact that it is firmware related - though it appears it's only impacting a percentage of users since Autel said "the occurrence is somewhat common with the new firmware". Not sure if that means most or a few or what. Either way, I don't think I want to play roulette with buying a refurb on the hope that it'll be a machine that isn't affected. I could end up with a lot of machines to sell very fast if I wasn't lucky (and I'm often not! ;)). If they'd send me one to use in the meantime that was confirmed not to be affected as WildDoktor suggested, that'd be a different animal.

    If I could somehow confirm that only older units are affected, I suppose I could play a game where I keep buying new units and returning them before the 30-day mark until a fix is released, but I'm not keen on playing the system that way - just not right in my opinion.

    I'll be asking more questions to see if I can figure out why it's only affecting some and not others. Guesses would be: older units only, units that upgraded directly from firmware 1.2.8 or earlier to 2.0.12 without doing one of the others in between, Android users, Samsung Tab A users, just dumb luck....the list is potentially endless.

    Yeah, I'm not exactly pleased - but I'm going to remain optimistic for now that they'll at least have a beta out in reasonable time that addresses the problem. I suspect the speed of it's release may depend on how many users are experiencing the problem - although the yaw issue affected everybody, and that took a year. We'll see.

    I have the same horizon tile, on both and the old unit and the refurbished. In reviewing my early shots there was always a slight tilt, but not that noticeable. With 2.0.12 it seams that I can wind it up and down depending on the yaw I use. I’m going to be doing a lot of flying this next week, I’ll see if I can describ in mode defined terms. I haven’t seen if adjusting EXP will affect the tilt.

    Thank you for posting this - and also making me not look crazy! (Had a few on Facebook...which is not a big help, simply reply "No problem on my end" [Gee, thanks for that reply] Few tips were given but nothing seems to work ) My own advice, Im staying away from FB!!

    Anyway, YES I'm still having the same issue with mine after this "Final (Beta) Firmware" Now I had to manually adjust my gimbal roll to -0.6 before every flight since I bought this few firmware, after the new firmware install last Wed. night it's been simply frustrating.
    I take it off from level ground, let it sit there for 30-40 seconds for the gimbal to adjust itself. Even a few Compass calibrations to see if this may fix it. I have to set the gimbal roll now to -1.4, -1.6 and it's maybe a TAD better. When I Yaw that tile kicks in and it seems it wasnt to slooooowly correct itself. So it looks like I'm flying a plane making slight turns.


    I am VERY glad Autel realizes this is an issue, so now just hope a quick update, maybe a 2.0.13 patch comes out SOON rather than later to fix this and we won't have to wait until 1st Qtr 2018! The last thing I want to do it send this in to Autel again, especially now with the Holidays coming up..By the time I send this in, by the time they finish looking at it, it's Thanksgiving week and I'm looking at another 5-7 days of getting it back. My warranty ends March 4..so I have time.
    ______

    First Test flight - also ** BATTERY Drop at the very end. I haven't had a problem with the battery since this flight.


    Last Friday 10-27 - Brief flight.


    Yesterday - 11-4. Take off and now trying to figure out correct gimbal roll again


    Yesterday 11-4


    Again 11-4 Tilt again at 1:48

    This may be kind of a "duh" noob post, idea. I saw this on Facebook a few minutes ago, then checked my rubber balls on the gimbal (I admit I really need to do this more often!). I do have a SLIGHT tear on one. A reply also stated how this corrected his tilt problem.
    Maybe....just maybe by replacing that torn rubber could fix...or at the very least improve the gimbal / horizon tilt. Odd though. I had a great flight on Tuesday with very little tilt, but then took it up last night and again it was really bad (adjusting the roll from -1.4 to -2.8 as I turned my XSP from a hovering position) . Very random. But I'll replace the rubber connections later...heck it can't hurt!

    Since it has been a brutal winter - either tool cold, and/or way too windy, I've been rarely taking the XSP up and it's been packed away. I finally did this morning and yeah...I actually forgot about this horizon tilt problem until I took it up.
    Obviously since that update in October we haven't has a solution, update to fix this. Not even sure if we'll even get one at this point since all focus seems to be on this EVO.

    Anyone get a decent updated answer about this? I replaced the rubber connectors, pins like it my previous post. No fix.
    I did contact them in Dec about crazy battery drops in % in my batteries AND mentioned the gimbal. They did replace my batteries, as for the gimbal, they just told me to calibrate the compass - which doesn't solve the tilt.

    It has been a very frustrating issue!

    Mine is getting worse
    Last two times mine is very noticable.
    Todays is just terrible after I turned left. Thought it straightened out for a few seconds and then back to the tilted horizon :(

    I'll contact them maybe later tonight sometime tomorrow - get a ticket issued and sent it to WA, been meaning to do this but simply forgot during the hectic winter.
    Hopefully they can manually adjust it - or whatever. I can get it back when before the weather gets warmer.

    Is this a problem caused by the new firmware, or is it something mechanical?

    Extreme cases are probably mechanical but there have been a lot more reports of the tilt after the last firmware update. One of the beta testers posted this just today about it.

    " During the closed beta testing the drone they sent me had horrible horizon issues, but the other 4 testers didn't see it as bad so we figured it was just my gimbal. A few closed beta versions later and the others started to see horizon problems. It all started when they adjusted how the drone flew in forward yaw turns. They never addressed it. Beta went public, people started seeing horizon issues more than normal, never addressed it. Firmware finalized with the same issue. Once the firmware was final I put it on my xstar and ended up with more horizon issues than it had before the update.

    Mind you, all drones have a horizon issue to a certain degree. My Yuneec Q5004K had issues, that wasn't fixable because it has no gimbal tilt adjustment. My xstar had horizon issues from time to time before the update, not as severe though. My Phantom 4 Advanced also has horizon issues from time to time. With that drone you can calibrate the gimbal, so usually when the issues show up you can just land, calibrate, and it will be good for a while.

    In all honesty I don't think Autel will fix it, or even release any more firmware updates. The firmware work on the xstar was mostly so they could get practice for future drone firmware. It doesn't really bother me though, it's an EOL drone. Even my Q5004K, which is still produced by Yuneec and has parts made readily available by Yuneec hasn't had a firmware update since around beginning of 2016 even though it desperately needed some tweaking. It's just what companies do when they come out with a new line."
