They look to be the type os systems used int he really cheap radio controlled toys you get, not a 'proper' RC system.
I presume you're looking for something to give 'tank' like controls from a standard radio control transmitter? - this is called 'differential steering', PIC's are commonly used to interpret the receive side and generate the required PWM for the motors.
meh, i think they achieve this with a single high power motor. The differential then distributes the torque into both sides of the tank. Now to make it steer simply apply a braking force to one side and all the extra power is now applied to the other side of the drive train nifty ey??
The only problem is that both sides cant turn at the same time in opposite directions.

For robots and models it's almost always done with two motors, one for each side. With two h-bridges and suitable software it makes it simple to drive, including turning on the spot.
