1. An apparatus for controlling speed of a battery-powered motor-driven radio controlled vehicle, the apparatus comprising:
a microprocessor having a memory; a power interface coupled to the microprocessor; a motor interface coupled to the microprocessor; a motor controller software contained in the memory and operable to apply power over the motor interface by controlling the timing and duration of voltage pulses; a dual-use connector coupled to the microprocessor, wherein the dual-use connector is removably coupleable to a first radio controlled vehicle component in a first configuration condition, and wherein the dual use-connector is removably coupleable to a programming cable in a second configuration condition; a programming update software contained in the memory and operable to receive update parameters for the motor controller software contained in the memory; and a port determination software contained in the memory that is operable to monitor one or more signals present on the dual-use connector and to determine, based on the one or more signals, that the dual use-connector is removably coupled to the programming cable in the second configuration condition.
