I had the original gimbal that came with my P2 a few years ago... so I believe it is the 2D gimbal. The original had a connector that went straight into the hero port on the go pro. That one got bent, so I purchased a H3-3D Gimbal. I hooked everything up, but noticed that when the camera pans, all I can do is pan straight forward or all the way down. I can not slowly pan down and or stop somewhere half way...its all forward or all down. Any advice? Oh... and I have never did a update to any of the software or any calibration. I tried to do a software update a month ago on a mac and I couldn't make it work and it is very hard to find P2 software. Any help on this would be great too.
