I have an issue with gimbal yaw on a P3P. When you first power up the drone the gimbal runs a calibration routine. After the calibration routine it is rock steady and tracks perfectly.
After it initializes it fails to track on the yaw axis. A sharp yaw input show that the gimbal is not tracking, and after the input you can see a drift. All three axises have noticably less torque and the yaw axis fails to track.

Startup Video:

Flying Video:  If I fly hard right or left, with the camera looking straight down, the camera ends up looking 20 degrees away. Here is a video of a roof, I'm flying directly to the right (after setting up orientation). Note how the camera tracks:

I have attached a zip file containing the TXT log file (from the SD card, see attachment below)


Has anyone seen this issue ?
I have calibrated, in this orrder: IMU, compass, controller, gimbal. The table is level, the results are always the same.

Also, I have the latest version of the phantom, controller and Go application.

It tracks the yaw axis perfectly for the first few seconds after the calibration dance. After a few seconds yaw tracking is horrible and it has drift.

Thats the same as mine.I Dont think its an issue.
Remember that its not a camera lock. It will have to move(drift) or your footage would be jerky.

Hello Scott A,

The behaviour of your gimbal is as normal as it should be. There's no tracking mode for a subject with the P3P. Actually the gimbal tries to smooth out your abrupt mouvements like it happens in the air when you have strong windgusts without any inputs from your RC. It prevents to get shaky videos. In the startup your camera seems to track something but thats wrong since the startup proceeding is not finished at this moment...

Hope this helps

The fact that your gimbal light is flashing red would indicate that there is a problem. If you haven't already, download the owners manual and read through the gimbal section.

I never noticed it before (it may have been the first time I've run left and right0, will see if I can check out a video online.

I'll toggle it back and forth (I've noticed that the Go app sometime has issues with single bit settings).

It goes away if I insert a memory card. I think Dji is trying to keep me from taking off for an epic shot, only to miss it (Kind of like taking off a camera lens cover

I still think your camera is in FPV mode. Look in your Camera settings. Change it to Follow. Press C2 on the underside of your remote to change.
To Check,Fire your p3 up with everything connected. Watch your camera as you move the right stick left/right. If your camera moves L/R then your in FPV mode.

I'ts set to Follow mode. The camera does move a slight amount (~5 degrees) when I give it full left/right input.

That's quite normal. The camera view is yawed by rotating the aircraft, not the camera on the gimbal, it only has a small amount of movement to try and smooth out the rotation of the aircraft. And once you point the camera straight down, it cannot move very far at all, it then relies on you flying the aircraft left or right.

I can't see any 'anti drop' plastic pins fitted on your gimbal in the first video. There should be two fitted diagonally opposite each other.

That was a good spot Aardvark! I'll try flying it tomorrow, with the pins installed.

Thanks Hawks100, patou72, DotheMath, Geebax and Aardvark.

You don't seem to understand that the camera does not rotate independently from the drone.  This is not an Inspire.  It only changes a few degrees to smooth out your start and stop yaw motions.  The fact that it does it when you fire up only means the gimbal isn't fully booted yet.  There's nothing wrong with yours.

I just ran a few tests today filming at a local park. The yaw drift is still an issue. Does anyone know how to report the issue to DJI ?

The gimball is not work propetly. When you turn forward, the back works well but when tilted to the right to the left, the camera rotates with the copter. On the Fpv Follow button, it does not respond. The firmware is latest .Error gimball does not show.
