The HD Special miniature .05 powered tether car was built by Doug Parker, of Vermont, in 2017. This handmade tether car was machined from solid aluminum and steel bar stock. It measures 7-5/8”-long, 2-7/8”-wide, 2-7/8”-high, and weighs 19.2 ounces. The Fuji engine connects to HPI racing gears with a 2:1 ratio that drives the rear axle. All wheels have ball bearings.
