I have a 4 channel (TQ4) TX and wanted to use it to control turning my light kit on and off. I found out that chan 3 and 4 are always hot though... i.e., when i hook up the lights to either of those channels, the switches have no effect (lights always on). I'd like to use the 2 position red rocker switch to control the lights. What do I need to do to make it on=hot, off=dead??
