Hello! I have a phantom 2 with zenmuse gimbal. I have connected to a transmitter Fatshark. I have 3 gopro camera and mini iosd. I bought plug and paly cable. I can't get any picture in my fatshark glasses from my gopro. I know I have the correct channel at Fatshark glasses. I get picture with Fatshark camera, but not with gopro camera. Do you have any tips on what I'm doing wrong? I get a picture in my glasses of the IOSD mini info. Do I have to setup my gopro correct?
