ok gents,

ive got a vintage tamiya king tiger. Im a jet guy and Im using my JR11x and a 921x ( flight ) rx in the tank, to get all the channels i need. I wanted to change the mechanical SC to an ESC to smooth the drive train. The traxxas esc I have doesnt seem to be compatible with my radio, it works fine in my ground 2ch radio.

so what esc can i use or what radio would be better for the application?

this is prob a stupid question, but I havent fooled with tanks much and havent raced cars in years.
thanks in advance for some know how.
