I already have the road wheels and sprockets. I bought a HL M41 and ZTZ99 tank today. I have a CNC and lathe at work that I use daily so I have no problems making any parts I need. I am going to start out with the triple linked drive chain for now, I know it is not the most accurate but for road driving it should be ok for now. It is going to have plenty of torque from the two wheel chair motors.
