2Ch. Transmitter w/ 3Ch. reciever

[Lothar13]

Just wonderig what the point of a 2 channel transmitter paired with a 3 channel reciever? does the third channel stay on? for example if i put a led string in the third channel would it remain on as long as there is power going to the reciever? that is the only use i can think of, if it will even work like that. I am looking at a cheap radio http://www.hobbypartz.com/79p-gt2-blue.html for my redcat rs10. I am not planning on comping as there is none in my area, and i do not use the steering mixing except to turn around in tight spots, when im crawling i like to just use FWS so i can keep my lines, so im not too worried about loosing the 4WS. I am also wondering if there is anything i need to know about switching TX and RX or is it mostly just plug and play.

it'll probably still get power...there just won't be any signal to it from the TX.
