Wow great idea car window motors... radio shack had nice electrical motor and gear set for sale for about 12 bucks each...
Hmm anyways I connected the all wires up with that dangling thing and the car has problems getting up the hill. I think its because there isn't enough surface area or the way the thing oscillates. Whenever the circuit connects I can see blue sparks flying out.. Is this bad?

.. I hope I can fix it in time the competition is this sunday, or maybe should i just scrap this design?
