I've been into rc planes for little over 2 years now and I'm getting more and more into slop soaring I currently have two zagi's both LE's that me and my gf mess around with the only thing is i've got one radio between them so i constantly have to switch out everything. well i was looking into getting a new receiver to start off with and i was seeing all this "channel 30 and 40 etc" buisness do i have to have the same channel for my transmitter as on the receiver or if they're both 72mhz it doesnt matter?
and if the channels have to be the same how do i know what channel mine is
