This was an interesting failure. The medium motor produces too little torque to turn over such a tall gear. There are other factors working against this engineering, too. In addition to the gear ratio, there are the extra number of steps taken to achieve the gear ratio. The gears are not lined up vertically, either, so one of the axles twists.

What could we change to make this vehicle work?
