pins 2, 3 and 4 of the motor section are brought out from three of the hardware pwm pins on the 18f8520 and can e programmed to generate pwm signals at frequencies and duty cycles other than those used to drive hobby servos. with a couple of hours of head scratching i was ale to control the brightness of a couple of leds based on the positions of the joysticks on the controller. more usefully, these pins could drive an h-bridge or something.

for more current you could connect the power and ground to multiple outputs in the motors section, or directly to the battery.
