P3S can't stay in one place in GPS mode, it's ridiculously unstable

[TheDoctor]

I don't know what caused it to happen, but lately the P3S won't keep itself in place. No matter what I have, if I have 6 or 12 satellites connected, it will go up and down and side to side like crazy. I've already tried IMU calibration. WHAT COULD IT BE?! Here's a video. The video is of me with my hands off the controller completely.

Edit: Here are the flight records. I think that Dat.129 is the one of the video, I can't be 100% sure though. It's one of these two links.
FLY129.DAT
FLY128.DAT

Have you checked that all your props are tight and not damaged? And tried refreshing the firmware?

Pull the .dat file from the aircraft from one of these short flights. You will need to upload that file to a sharable location such as DropBox or Google drive. Share a link back here to the data file. If you don't know how to get the data see the link below. Someone will take a look and see what is going on. ( Unless of coarse this is wind related )

Okay, I'll try that as soon as I get to my laptop. It's not wind.

Yes, get your .dat file as requested, one other thing you can do yourself, if your flying with DJI-Go (Stupid Name). You playback your flight and there is a option you can see your stick movements.
In other words was your remote sending out stick movements.

Anyways I bunch of would like to so why your Phantom appears to be F.U.U.Intoxicants.

The OP stated that the controller was "Hands Off" during this video......Did you miss that? LOL

Here are the links
FLY129.DAT
FLY128.DAT
I think the video one is 129.dat but can't be 100% sure.

No, that was my point , the remote could have something wrong, maybe bad potentiometers are causing the issue.

If he plays back his flight with the app and sees remote control stick movements which he knows he didn't do. Then we have a different starting point to the problem.

Let me know if I'm still missing something.

To the OP,
Please take the time to find and upload some .dat files from the Phantom. It can be really confusing to some, been there.
A lot of us would like to see it.

Yep Rod, I just updated it a minute before you posted.

 

[Pharm]

Did you calibrate the controller as well?

 

[TheDoctor]

Did you calibrate the controller as well?

Yes. The controller was perfectly calibrated and I even recalibrated.

 

[Pharm]

Yes. The controller was perfectly calibrated and I even recalibrated.

Hmmm...I’m out of ideas.

 

[Fly Dawg]

Still looking through this data at the moment. It appears that you manually switched out of GPS in to ATTI for over half of the FLY129 flight. That would explain the drifting around somewhat. This is just a preliminary peek.

Disregard Post#13 in the interim.

@sar104 , @BudWalker .....................Referral for IMU data.......

Thanks. I hope I can get it working properly again.

Thanks. I hope I can get it working properly again.

When I attempt retrieving the .DATs I land on a page that wants me to sign up for some music app. Maybe you could try a different download service like Dropbox or GoogleDrive.

 

[Fly Dawg]

@BudWalker .......Just FYI..It is a share site. Just click on the upper right download button. I got them with no problem. Just not familiar enough enough with the IMU data portions.

I do exactly that and get

Maybe you could Dropbox it

Okay I am uploading them to google drive at the moment. I'll put em here as soon as they're done.
