is there any such thing as an rtf or arf that includes the engine speed control batteries, servos. that will run on 72mhz. id like an electric but most of the arfs i see will cost you $400 bye the time you buy all the junk. and most of the rtf's ive seen run on 27mhz. i have a 72 rx and just wished there where rtf's that dont come with the rx. and wont cost you an arm and a leg.
