thank you very much.
I'm using the Amimon Connex. You can see it above the camera. It is that silver piece mounted to the gimbal. I am running the gimbal, camera and video downlink completly separate from the copter. There is one lipo at the back of the gimbal that provides power for the camera, the downlink, the gimbals receiver (which also controls the shutter cable) and the gimbal itself. There is no electrical connection between the copter and the gimbal, so that I can pan indefinitly and don't have to disconnect anything when taking the gimbal of. Furthermore I am able to use the video downlink when using the gimbal in handheld mode, which is quite convenient.
