I'm thinking of using the servo motor, and the first gear it touches turning a tiny threaded rod with a nut that actually moves the wheels and ditch the rotary POT and use a slide POT that is keyed to the nut.
The idea is to spin the threaded rod and have the nut move back and forth.
The nut would most likely have to be made since I think it would need a guide rod to keep it from spinning and the slide POT could lay right next to all this.
I would have to make a bracket to hold it all.
I havnt even mentioned how I plan to connect to the tierods.LOL
Or maybe just a compact worm gear setup and use the stock motor and POT.
These are all just distant idea's right now though.
