This hybrid dragster tether car was made by Doug Parker, of Vermont, in 2016. This unique blend of power from a Cox .049 combined with the boost from an Estes A3-4T rocket motor is, perhaps, the ultimate in micro hybrid tether car racing. It measures 9″-long (including the tail skid), 3″-wide, 2-7/16″-high, and weighs in at 12.1 ounces. This sleek dragster body is machined from 6061 aluminum bar stock with tool steel axles, panhandle, and tail skid.
