I have 3 cars i would like to operate off one remote, i have a tmaxx, so keeping revers would be nice, but that would mean I would need a 3 channel radio. I have 2 other cars but hose are just 2 channel. The cars I have are only made in RTR so I have remotes that I constantly have to remove batteries from to charge etc....My father has a rmote for his planes that supports like 10 planes or something like that. i'm just getting back into r/c and would like to simplify things by using one remote for all the cars. Is this possible?
