How many R/C channels does the controller use?
Typically 2 and up to 3. Two channels are used to set the commands for motor 1 and motor 2. The two R/C channels can me “mixed” to cause one channel to set the forward/reverse direction and the other the left/right direction when both motors are used together to move and steer the robot. The third channels is used to activate up to two voltage outputs on the controller and to drive miscellaneous accessories (lights, weapons, horn, solenoids,…).
