think I am going to order that motor just for kicks, but I have a traction concern even now. Wonder how I can get the M18MT to hook up better. Maybe its time for some pin style tires. I am sure to give them a little stretch at that kinda RPM. Think its about time to fab up a 12v batt too, too bad I only have Nimh....kinda heavy but comon: 110,400RPM it should move somewhere
