I just picked up an RS2, and I'm experiencing the violent flipping also. Seems to be when activetrack subject gets out of frame? Not awesome to see this thread is a year old with no resolution

Concerning eh? I noticed DJI asked questions in here and as soon as I answered they disappeared.

Brand new RS2 in 2022 and same exact issue.

Perfectly balanced and calibrated. Then suddenly turns violent and flips about with no way to fix it. Seems more prone to occur when going into briefcase mode or tilting the gimbal.

DJI fix this! Come on!

Have you had any resolution or update on yours?

I've been asked to ensure balance is perfect and auto tune. If it still doesn't work, then reset everything and repeat. And if it still does it to send it in for repairs....

From what I've read repair/replacement takes a long time and supposedly still hasn't fixed anything.

Today I decided to check if my RS2 makes such a sudden flip when switching to briefcase mode. And you know what? Yes, it started to act crazy - it turned his head, ran into the limiters a couple of times with a terrible sound and froze with the camera upside down. I had to put it to sleep and manually align the camera position.
This whole story happened with quite active panning in briefcase mode.
DJI, what's the problem? Why does a 1200 bucks device behave like this? Why should I be afraid for my equipment, which can be damaged by such tricks?

Hi guys,
I had the same problem with the violent flipping during active tracking. I tried the following, it seems that the problem is gone ever since:
1. Reduce the tracking speed - I set the speed to 22 when using Sony GM 14mm/F1.8
2. Set the end point of pan axis in M1 mode to 175 - 175, the default setting was 180-180
Hope this would work on you DJI RS2 too.

No, no responses from them. They've essentially ghosted me.

They ghosted you on the ticket?

In mine they keep insisting I return it for repair/replacement. But seeing this thread and others I doubt it's a problem they can fix by 'repairing/replacing'.

Is yours one side heavier than the other?

Do the issues exist without active tracking raven eye and phone plugged in?

1. Reduce the tracking speed - I set the speed to 22 when using Sony GM 14mm/F1.8

Did you try either one alone or was the combination necessary?

So active tracking with raven eye on your phone works with those setting changes?

I just got mine, sane thing is happening to me! Maybe the latest firmware update might help?

Just got mine and it does the same, when i move too fast in normal mode with no active tracking engaged. Not the greatest look when filming public events.....
I am using an FX6 on it so not a supported camera.... anyway still learning how to use this thing, loving the shots I'm getting though!!

Hello everyone!
I just created this account to share my solution.

First off, I'm very unhappy how DJI handles this situation, very bad customer support.
I like their products but this behaviour is absolutely dissapointing and yall should be ashamed of yourselfs!
Customer Support is the one and only thing that will let you keep customers, otherwise there will be a brand that sees this gap, invests in it and all of us will probably follow them since they care about our issues with your product.

djiuser_9bLSTSC8DmQF was on the right path, I think this issue could be easily prevented with a software fix.
I noticed this behaviour as well when I was using Active Track in Briefcase mode and on a couple other occasions.
I  was able to reproduce the issue, even being affraid of damaging my gear, but I wanted to fix it before I go out to shoot a clients video.

So enough said, here is my solution:
The issue typically arises when the Roll axis is maxed out and the camera has no room to move anymore.
I was able to reprodue this a couple of times.
Everytime the roll axis was touching the pan axis and it kept pushing it, resulteing in a total violent spin trying to fix the "inbalance".

I could fix this behviour by going inside the ronin app and doing following things:
1. Go inside the app and open "User Profile" in the botom left.
2. Click on "Control" in the very bottom. (I'm german so not sure if it is written exactly like that)
3. You see the "Channel" and "Movement" tabs in the top. Open the "Movement" tab.
4. Reduce Pan Axis Endpoint to 175 on both sides.
5. Reduce Roll Axis Endpoint to 10

After I've set this up I tested in briefcase mode as well as normal rotating, making the roll axis touch the pan axis.
Now it just stays at that point and will eventually trigger an alarm due to overpowering the motors or due to inbalance.
The balance icon on the gimbal touchscreen then appears red.
It will stay in that position until you back up and get the axis away from each other.
This is not a perfect result but by far better than having fear to damage my new gear.

Plese let me know if it helped anyone!

Hello everyone!
I just created this account to share my solution.

Did you try your possible workaround with/through raven eye system connected too?

djiuser_slVkdfWpXirA Posted at 3-24 14:27
Did you try your possible workaround with/through raven eye system connected too?

Hey, yes I tried it while using Raveneye.

I found this workaround only fixed one of the possible ways the gimbal flips the camera.
The issue when the two axes touch is resolved with my workaround, however I found out that while using active track it can still happen that the gimbal spins the other way around, when the roll axis is at 180 degreese and pushes further, then it will result in a flip aswell.
However this workaround has at least decreased the possibility of a flip for me.

I will continue testing different settings on the gimbal to see if the second issue can be resolved as well.
I could think of it having to do with the set stiffness of the axis, as it always happens due to compensation of the weight.

I will update you when I have news!

Just want to come on here and mention what's happening to me.

I'm having the same issue as all of ya.
When I purchased the gimbal it was completely fine. Been using it for about 9 or 10 months now. I've used it with heavy set ups and light set ups with out any issues whatsoever.

But now all of a sudden, it has started to violently flip around when ever it decides to go about doing that. Heavy set up or light set up, it doesn't matter. It's getting worse and it's getting impossible to work with this thing. Also it almost ripped my flip LCD screen off of my Sony fx3.

Ive tried everything... different calibrations/ different motor settings / balancing millions of times... etc etc etc. nothing works.  
Ive never used the raven eye. not even the focus pull motor. So I'm pretty positive it has nothing to do with that at least in my case.

I have noticed tho that it happens mostly when going into briefcase mode... or doing a move into briefcase mode. sometimes its fine in briefcase mode and sometimes it wants to kill my camera violently...  therefore I feel like this must not be a software issue.... there must be a cable or some connection in there that once you do a certain move of some sort, it simply triggers it, or disconnects for a brief second and the gimbal doesn't know what to do to recover and just goes absolutely wild. Maybe a loose wire, or a broken cable or a loose motor sensor.  Im not an engineer so I got no idea what's in there, but something must be disconnecting for a brief second.

There are over 3700 views on this thread, so we we can't be the only ones having this issue, i'm sure someone has sent theirs in under warranty...?

Has anyone here sent theirs in for repair under warranty?

I do believe I read so yes, a could of replacements and many of us have brand new units. Happening to all of us and briefcase mode also seems to aggravate it.

I just bought a brand new rsc2 and installed my brand new canon 90d on it. I balanced it, I auto tuned it and started working with it. It worked really fine for a bit then the whole thing went beserk and flipped upside down. I am really relieved the camera did not get blown away or broke, but these random moves were really unexpected. I came to see if there was a solution but it doesn't seem to be the case for years?

This can't be right ! There must be a clear solution or something ! This gimbal is so sturdy and seems so reliable... Incan't believe this happened. I mean, if the strain on the motors is too hard and makes it flip, the processor should simply stop all movement and inform the user that sonething went wrong !

Is there a solution coming? Should I return the gimbal to the store?

Thanks,
Vincent

KARTA Posted at 3-18 18:39
Hello everyone!
I just created this account to share my solution.

Hello German friend,
I'll try this solution on my brand new rsc2. I can't believe this, I tried some movements with the gimbal and the whole thing flipped suddenly without notice. You are 100% right about customer service. I came here for an explanation but there is none and no solution on their behalf, that's crazy unprofessional.

This happened once for me. It was when tracking was active and the subject went out of the frame. Since then never tried to use tracking again.

Hello everyone!

I have exactly the same problem with my new RS2. The DJI Support asked me to make a video of what was happening. Unfortunately, I can't and don't want to consciously reproduce this because I'm also worried about my camera. I sent the gimbal back to the trader because I wasn't sure if the hardware might also be the issue for that behavior. Today, I have received a brand-new RS2: And you know what? With the same problem again...

I don't have the RavenEye and the problem only occurred in briefcase mode so far. The last time I did a slightly faster movement, the camera turned wildly again.

Thanks @ KARTA & djiuser_9bLSTSC8DmQF for sharing your workaround! I've now taken over the settings and I really hope that this doesn't happen again. Since it doesn't seem to be an isolated case, I also hope that DJI will act here as soon as possible and fix this on the software side.

Do you have any news on this in the meantime?

Best regards

Yet nothing but silence from DJI despite many people having issues.

Hello Karta, Sqiddy666 and djiuser_9bLSTSC8DmQF, I have been following the string and wondered if there are is permanent solution or an update from DJI with an update. I have had this issue for time now and it seems that it does it when I lower the gimbal to take low shot films. I will try the adjustments from Karta and djiuser_9bLSTSC8DmQF, however, there must be a solution from the company as this is a very inconvenient and potentially destructive for my equipment. A sony alpha 7RII and a sony f16 - 35 lens.
Cant believe they are ignoring this issue...
Thanks for your assistance

KARTA Posted at 3-18 18:39
Hello everyone!
I just created this account to share my solution.

Thanks Karta, this seemed to fix the issue but I have yet to test in fully in action.

Any update on this? Having the same issue with RS3 and RavenEye

I had the same issue using briefcase mode, then just when tilting downward but now my RS 2 spins, shakes, and flips when I turn the power on. Funny thing is it only started happening after the Ronin  app crashed. The app was unavailable for a week, and then downloaded the app again. I just emailed DJI. If they don't fix this I'm sure there will be a class action suit coming.

Problem Solved!. I read somewhere a while ago to reset the stiffness in Motor Parameters lower. I reset my Tilt -24, Roll 38, Pan 24 manually. After you calibrate or Auto tune you have to reset your stiffness manually if the numbers are too high.  Mine were in the upper 30's or 40's. I have powered up several times now and put into briefcase mode and the flipping, spinning, and shaking are gone. Hope it works for you all.

I bought the RS3 Pro Combo a few days ago and it does precisely the same as you people had described.

Before reading this thread I believed it was an issue of the tilt axis reaching its maximum and then attempting to flip in order to invert, and then going nuts because I was actually staying in the briefcase mode. I had the angles of my axes reduced depending on the size of the lens, position of my phone in the holder on the gimbal etc. It happens (to me) no matter the angles adjustments, follow mode, and so on, but I think it only occurred in briefcase.

Hey, thanks for sharing you adjustments I was just complaining of that flipping. I'll try you settings in the morning. But... which gimbal do you have? Mine is the RS3 Pro.

I am still hoping this is something that occurs because of some inadequate adjustments/movements/angles during use, and that clicking the right buttons in the menu will resolve it. I certainly don't want my gimbal broken, or my A1 smashed.

It's an RS2. Just tested again this morning and working as it should. Lower your stiffness settings.

Elite North VM Posted at 8-15 04:49
It's an RS2. Just tested again this morning and working as it should. Lower your stiffness settings.

I went out to play with it quite a bit now. Mine is an RS3, but the symptom is the same and so I assumed is the problem/solution. If lowering stiffness solved it for an RS2 though... that means there is a difference, because in my case that did nothing. I tried.

However, after the first flip today I re-did the balancing and calibration, checked it to make sure that part is right. Then I kept working with it in all modes, at different speeds, different types of movements. I spent extra time using the gimbal as a flashlight. It never flipped again, and that was because I was careful to recenter the camera (double click the trigger) whenever I was significantly changing the inclination of the system horizontally.

Basically, if you go close to the so called flashlight mode, recenter the payload before you shoot. I think that lets the system know what's going on. For some reason it (I think) thinks it is being inverted and attempts to flip and level, but unsuccessfully, because that's not what's going on, and then it just crashes somehow.

I did this with calibrating in both normal and super smooth, the latter having much higher stiffness levels. No flips, all good whatever I did, with a habit to recenter the camera quite often.

Also, an advice to everyone who had their payload hit the gimbal during these flips! Make sure to balance it so that it doesn't touch the gimbal throughout its movement range. I learned that lesson after my lens hood hit the gimbal during a couple of flips, for example. I thought it was all safe cause I had the angles set manually for each axis via the app, but those limits, while good when things are fine, go out the window during the flips. In my case, I renounced on having the hood on on my Sony 24-70 2.8 GM. That also means I won't be using all its focal range, because it extends when zooming. This "loss" is somewhat compensated by going into apsc mode. It works for me when shooting in 4K on the Sony A1 at least, because the resolution doesn't change during the switch (the sensor is 8k, basically, so the camera does its things and keeps shooting 4K). OK. So, you should not use a combination that can not be balanced without the possibility of hitting the gimbal at some angle.

Right now my batteries are charging, after which I'll go out to test everything one more time. I have a shooting with a client on location tomorrow, so this gimbal thing should function properly. If something worth sharing happens I will post it here.

Cheers!

I spoke too soon. The problem is back again. I sent a video of this problem to support. We'll see what they do.


So may of us spending countless hours to figure this out. This is unacceptable. Personally I will not be satisfied unless I receive a brand new replacement unit, free of course.

Elite North VM Posted at 8-16 03:13

Understandable... That's annoying to the max I hope you don't have to wait too long for a replacement though.

Mine performs well as long as I am recentering it before its angles reach maximum range. If I'm doing a lift, for example, from ground to eye level and/or tilt, I have it centred somewhere in the middle and it works without issues.

Today I worked with it for 2 hours in the morning + 2 this afternoon. It flipped once today, when I forgot to recenter.

I wish someone from DJI to clarify this thing. I'm gonna try to find someone with some serious experience to ask.

I'm thinking a replacement wouldn't fit it, there seems to be some kind of software/firmware issue that could cause it. If it's happening with the RS3 as well it's something weird going wrong.

Squidy666 Posted at 8-17 02:41

Yep. I agree with Squidy here. So, the RS3 Pro just came out and does the same thing.

I believe there are two possibilities here. Either we who experience flips are doing, or not doing, something in the way we operate our ghimbals, ort here is indeed an issue that occurs in some copies of the models that use some of the same software (or hardware).

It is possible that a firmware will fix it in the future, and is also possible that it will never be acknowledged, which would explain DJI representative leaving this discussion after leaving one very general comment that resolved nothing.
Sony did something similar recently. I bought the A1 as soon as it came out. Among other things I bought a 70-200mmf2.8GM lens, both top of their lines at that moment. It was causing the camera to crash. 20secs of uselesness. First 10secs it wouldn't even switch off, unless you took out the battery, after which it wouldn't focus nor shoot for another 10. When I contacted Sony they asked me to film it when it crashes and made zero attempts to explain possible causes. Much like I read other people's experiences on this forum. The cause was incompatibility of the lens with the camera. An update fixed it a few months later, with no explanation.

Look, I just came home from another shoot with the RS3pro - no flips. I worked with it as I had described already. That being said, none of my moves required working at extreme angles and I did not feel like pushing it unnecessarily. Warranty is 2 years and I trust my vendor. As long as it does what I need, we're fine, I guess.

Below is the reply from DJI support. I'm waiting on the "repair request". After I did all they recommended my RS2 is now completely unusable. It just goes haywire and goes into sleep mode.  I'll post an update after the outcome.

Dear Elite,

Thanks for your information.



I have watched your video, sorry for any inconvenience caused by this issue. Please make the RS 2 in sleep mode when this issue happens in order to protect your camera and gimbal's safety, here are my suggestions for your reference:



1. Please re-confirm that the mechanical balancing of the three axes of your gimbal has been correctly done.

The most accurate judgment method of completely balancing:

Connect to your mobile device, launch the Ronin APP, find the "motor parameters" setting, click "more parameters", and check the power values of the pan axis, pitch axis, and roll axis. After the Auto-Tune is completed, the smaller the power value, the better the balance status. If it exceeds ±5, it is recommended to re-adjust the mechanical balance before performing Auto-Tune.



Before Auto-Tune or after the mechanical balance is adjusted, it is recommended that the power values of the pan axis, pitch axis, and roll axis are all within ±5 before performing Auto Tune.



2.Connect your Ronin APP and complete the following operations one more time:
1) Complete "Restore gimbal parameters".
2) Complete "System calibration".

3.Enable "Disable 3D Roll 360 switch".





4.Set the "Push mode" function to off.


If the situation is still the same, please send back your RS 2 to DJI for testing and repair. Upon receiving your product, our engineers will check everything and list the items of repair that need to be carried out, which will be sent to you in the quotation email including the damage assessment results and repair costs.

Not resolved for me, but I haven’t been able to send off my unit to DJI for them to investigate yet

What is your active track settings set to? I had mine on max and my camera was going all wonky and spinning all over the place. Then I set it to 9 an its perfectly fine
