How to make a silk purse out of a sow’s ear ;-)) The Auto World Super IIIs have had a terrible time in the market place. A lot has to do with the parts spec from the factory and the terrible QC during assembly. You can make a Super II sing by covering the basics of hop up – good axles, tires, gears, and motor. The parts used in this demonstration retail for less than $15.00 per car. Putting in a built up rear axle set will further improve performance.
