The RCIC-1 (Radio Control Interface Chip) is a preprogrammed PIC mounted on a daughterboard which plugs directly on an MC7 motor controller. It accepts a standard 1 to 2 ms RC pulse and outputs logic level direction signals and PWM pulses to the MC7 to control speed. You have full control of the motor controller for direction and continuously variable speed. This gives you a 30 amp radio controlled Electronic Speed Control.
