How many radios? I'm basically new to rc (been a few years) I have a Hitec 3 channel I thought I could just pull the guts out of my low wing skimmer and put it into the super cub I'm building, after finally getting the servos in place in the skimmer there's no way I'm taking them back out, should I buy more servos? Or a new radio system, that eventually I will want more out of like at least 4-5 channels, I can't see (or afford) a radio system for each acft... any help would be appreciated thanks, Hercules
