Pan, Tilt

Frosty · Aug 2, 2025

I’ve looked through the forums to see if anyone else might have had this problem, and I’m either I’m not looking in the correct spot, or maybe searching with the wrong Key words, but here goes, and sorry if this has already been answered.

I have a Q500 4K. I flew it a lot when I first bought it. Then it probably sat on a shelf for a couple years. I took it on a vacation, still worked fine. After the vacation it sat again for a couple more years. The first time it was in its case all safe and sound. But this last time it was sitting on a desk, surrounded by papers, maybe getting nudge a couple times (the camera) I didn’t have the camera protection on it. I have never crashed the drone, and have never landed it hard. There is not even a scratch on the drone.

I took it out to fly about a week ago, and found that the controller and the drone would not connect. I had a blinking blue light (I think it was blue) the one that is telling you the drone is not connected. So I went through the process of trying to bind the two together, by tilting the drone at a 45 degree angle back twice until it was flashing orange. But still couldn’t get them to bind. While trying to bind them I got a message asking if I was sure, because it was bound to another. (Side note, my brother has the same drone, and I was thinking (possibly) our controllers got mixed up.)
After numerous times trying to bind, I finally did a controller/drone reset. Went back into settings and made a new profile for the drone on this controller. (I maybe wording it incorrectly, sorry)
After I did the reset, and finally got the two to bind, I had control of the drone.

Now on to my question, sorry for the “Book” but I wanted to make sure I included everything that may have caused my problem.
When I first started to fly the drone, after the reset, the camera was acting weird, the pan and tilt was way off. With the side adjustment all the way up the tilt was pointing somewhat down, and the picture was not straight, the picture was tilted to the left a little, about 20%. After I flew it until I got a battery warning on the drone, I turned it off, brought it in, put it on the dinning room table, and turned it on again. The problem seemed to be gone. It was straight, and the adjustment was working too.
But…….lol, yesterday when I flew it, the camera started out fine, but after I flew it for about five minutes, the camera tilted sideways, the picture was showing a left tilt when I was going straight. But before I was done flying, it seemed to straighten out.
Is there something that might need cleaned, or maybe an adjustment on the gimbal I need to do, because it sat for so long out of its brace, and occasionally getting bumped by piles of paper on my desk.

Even though I’ve had it for this long, I never did any real reading on the drone until now, the in’s and out’s of the drone, the “Inner workings” of it. I know not the smartest thing to do. I haven’t even done any firmware updates, if there are any.

Thanks in advance for any info, or maybe pointing me to a place where I can read up more on the gimbal and how it works. I’ve read the manual, that has little info on how the gimbal works, unless I was reading the wrong thing, the manual was no help at all. I’ve tried googling the gimbal, and just can’t find what I’m looking for. I found these forums last week, joined today hoping someone could give me a little info, or point me in the correct direction.

One more thing, if my controller and my brothers controller got mixed up, would I have to do a calibration?

No calibration. The binding would have been all you need if mixed controllers were even the issue.
Which camera do you have? CGo2? CGo3?
Which controller do you have? ST10?, ST10+?

Frosty · Aug 2, 2025

CGO3, ST10+

WTFDproject · Aug 2, 2025

With a CGo3 that has been idle for a while, the first thought might be spontaneous decomposition of the encoder magnets. The magnets become weak before they actually start to decompose. And there is a stage where the magnetic force is strong enough to avoid beep codes, but not strong enough to provide reliable function. I will not be very available on the Forum for the next couple of weeks.
I hope @Vaklin, @h-elsner, @Steve Carr or others can help.
A quick check would be to swap camera's and controllers with your brother's drone to determine if the problem is associated with the camera, the controller, or the drone.

Frosty · Aug 2, 2025

Ok, thanks for the info. I’ll see if I can get my brothers drone to do some testing. But if that is the problem, the magnets. Would I have to buy a new gimbal, or can I replace parts. I know you said you would not be around, so thanks again for the info.

If there is anyone else that might know if I would need to buy a new or just replace parts. I’m going to look up the gimbal and see what info I can find with the new info I have.

1) The binding problem. You are absolutely right to create a new model in the ST10 and bind to this. To start with a new created from scratch is the solution for many strange problems that may occur for the Q500 but especially also for the Typhoon H where you can do things with the Channel settings with unexpected outcomes. A new model solves a lot.

2) The camera. Hanging on one side in the roll position is a well known problem of the CGO3. I think it has something to do with miscalibration of the IMU due to aging or something else that happens to this chip. The IMU is a chip that combines 2D gyro and 3D accelerometer (MPU6050) that tells the gimbal how the camera is positioned in all 3 angels. I had this problem too. A workaround is to hold the camera in an extreme position on the edge of its movements and switch it on. This seems to force the IMU to find its position and rewrites bias data. For me that helps after several tries.
The Typhoon H has a camera calibration function that do accelerometer calibration. My understanding is that Yuneec identified this problem with the IMU and offers a solution for the CGO3+. But they did no more for the CGO3.
However, now we have the possibility the calibrate the gimbal of the CGO3 too. All you need is the YUNA100 (the white dongle) that came with a short white cable called Gimbal adapter lead. With that you can connect the gimbal to your PC. The connection (page 2) and the calibration process is described here:

I would start with "Acc cali" first without deleting anything. This seems to be the same as the Typhoon H has as standard.
The calibration tool itself you can download on the download page:

It is called "CGO3oldCali".

Thanks h-elsner,
I will definitely be trying this out. I’m hoping the camera is doing this because I was lazy, and didn’t put it away in its case.
Sometime today my H is arriving, I’m super excited about that. I’m hoping with your info I can get the CGO3 working. Then my husband and I can go flying, with both video recording.
Thanks again, I’ll let you know how it goes.
