Ok once again I thought I had everything I needed. I have the Predator V2, and bought this http://www.readymaderc.com/store/index. ... ts_id=1296 I've watched Youtube videos and none look like what I have. Do I really need another cable? I have this cable from GoPro to Tx, then there is a cable from Tx to little circuit thingy, but doesn't seem to be a way to hook it into the power source.... help please... I can take pictures tomorrow.
