Alright - this is very interesting...First off, a2hill - I'm going to give you a link ref that will probably help you:
This is awesome information cr0sh, could you suggest any more online resources that give information on hacking toy R/C cars?
You have been following this thread, I take it?

Not that it imparts much more knowledge; but it may help. Basically, if your car uses the RX2/TX2 chipset, it can be fairly easy to hack it to control the car with the Arduino (note that intercepting the signal sent by the transmitter, via the RX2 (to pin 3) is going to be a tougher challenge, but probably doable with the right tools - most especially you would want a good oscilloscope; a DSO would be preferred). If your car uses something else, and you can't find a datasheet for it (though most cheap R/C toy cars today do use the aforementioned chipset), you need to trace the motor/actuator leads back to the PCB, and trace out the h-bridge or other driver circuit being used, until you get to the current limit resistors; at this point you would want to measure the voltages involved, and use ohms law with the resistance to determine the current, and change what you need at that point to suit the Arduino. Hacking hobbyist R/C cars is a different beast altogether; if you are just trying to control the vehicle, that's easy (use the servo library); if you are trying to interpret the R/C signals controlling the servos/ESC - that's a different matter (though people have done this, too).
