right now neither one of them have what i need to make them work. so there is no pictures of them in action.. you take a moter, and put a gear on it. then you take a piece of hevy duty string and hook it up to the the motor, and then to the wheels (axle). that's what i need, the string.. after a little bit of playing with it the line breaks. maybe i can go git some and get a movie up for you guys. jason
