I want to install a receiver controlled relay switch in my P2V+ ( http://hobbyking.com/hobbyking/store/uh ... oduct=8833 ) to control a headlamp. Physically I see there are lots of channels free on the "Phantom"-labelled NAZA. I just want to be able to set a channel high or low from the 5.8ghz transmitter. I guess this probably means using the "tilt" channel. Anyway, has anyone done this?
