Motor Control Options
The TCB has multiple options for controlling the main drive motors, turret rotation, and barrel elevation motors. Using the OP Config program, you can select which type you want to use for each motor. Options include the two onboard brushed motor drivers (typically used for barrel and turret motors), RC output (for all RC hobby brushed or brushless speed controllers, Tamiya DMD units, or continuous rotation servos), or serial output for serial-enabled dual motor controllers.
Because the TCB's onboard brushed motor controllers are limited to low current, they are really only useful for turret functions and will not be powerful enough for the track drives on 1/16 scale models. This means most users will be required to purchase either hobby ESCs (brushed or brushless) or a serial dual-motor controller to power the tank's drive motors. Yes, this is an extra expense, but this design decision was intentional. It matches what every other segment of the RC hobby is doing and gives you virtually unlimited choice to select the controller that best meets your specific needs.
