For tank control with brushed motors, you would hook up all motors on one side to a speed controller, and then hook up all motors on the opposite side to another speed controller. With brushless motors you need brushless speed controller for every brushless motor- no matter what. TO make a robot that can steer you need at least one motor, speed, controller, and a servo (like a tricycle), or you need two motors and two speed controllers. THere is no way around it.
So for the drive wheels use brushed motors even if brushless gets you better performance becase it's just way simpler since you need a lot less speed controllers and the speed controllers are cheaper. For weapon motors brushless are higher performance.
TO wire it to a remote just run the PWM line form each speed controller to a receiver (which you should also have an RC transmitter for). One remote is not the issue here and you shouldn't be worrying about it. More channels just means more expensive transmitter (remote) and receiver.
