If I'm following correctly, a RC radio system won't drive motors directly. Need a electronic speed control (ESC) to take the signal from the receiver of a RC radio system, the ESC can then drive the motor.

ESCs are available for brushed, and brushless motors. Some can do both. I'm guessing you may be thinking a brushed (DC) motor?

Lots of radio systems are available. Perhaps check a large online source like Amain to get an idea of whats available.
