Gimbal Pitch correction reversed...Help

[becma27]

I have a Phantom FJ40 and purchased a goodluckbuy gimbal to install on it for use with my gopro 3. Install and setup seemed pretty simple, but I have a small problem. When powered up, the pitch correction is off. The automatic pitch correction acts in the opposite direction of how it should, so instead of stabilizing the camera motion, it makes it worse. The roll correction works as it should though. Is this a Naza software issue or a simpleBGC issue? I did plug the gimbal in and run the simpleBGC, and tried clicking on the invert check box for Pitch with no effect. I also did the the Motor config "Auto" and did the "calib.acc" for the sensor, none if this corrected the issue.

Which pin on the gimbal is the control cable connected ? Should be the top one on left when facing .

Sent from the thing that does everything.

Yep, connected to the top left pin when facing it.

Then you need to make sure the cable is connected to the bottom pin in F2 socket in the Naza box inside the Phantom ..

Then if still wrong adjust the min centre and max numbers in Naza software .. should be -1000 , 0 , +1000..

If that works then you can fiddle with those numbers to control the Pitch movement from front to down ..

Mine is set at -250 , -550 , -900 ..

Thanks Mandrake...checked the connections, all are correct. After investigating further, it's definitely in the NAZA side of things. With only the gimbal powered, it stabilizes perfectly, but as soon as I power up the Phantom as well, it does weird things with the pitch when trying to stabilize.

In the NAZA software, what is the optimum frequency for the pitch control? Mine is set at 50mHz now. What about the gain numbers for the pitch? Mine is at 20 right now. I'm a bit confused with what the min, center, and max numbers do, is that limit numbers for travel? Seems like that wouldn't be causing this problem.
