Hey all, I'm adding fpv cameras to my rigs with 5.8 tx/rx. I bought one iftron tx and one readymade tx to compare. They both have similar wiring, with a yellow wire for the video signal with a bare lead. I snipped a male RCA plug off a cord and soldered it to the yellow lead so I could connect to the camera's female RCA. The RCA cable had two leads inside the insulation. I read somewhere that you just twist the two together. Is this correct? Seems counterintuitive. Also I'm powering the camera through its barrel plug, so I can just cap the power leads from the tx, correct? Thanks much if you can help.
