I'm trying to connect a gopro 3 to a Fatshark 5.8G 250mW TX to use with my Attitude goggles. I have bought the necessary cable from "Readymade" to connect the gopro directly to the video TX, but have been unable to get video to the goggles. I am powering the video TX with the Phantom's 11.1 v battery through the fatshark filter that came with my FS Attitude. I am a newbie at this, and I do not have a degree in electrical engineering. Please, please help.
