1983 US Expert Builder catalog

The Dragster featured rack and pinion steering connected to the steering wheel via cross axles and 2-cylinder engine attached to the rear axle by a spur gear and differential. A chain drive attached to the spur gear spun a cross axle, simulating a cam shaft. The dragster achieved a somewhat realistic appearance by using pulleys for the narrow front wheels and the large Technic tires for the rear. The tapered body, with an interesting blue and white color scheme, was achieved by using hinged bricks. The original steering linkage proved too fragile and later versions had an insert page showing how to rebuild a stronger linkage. Overall an interesting and rather difficult to find model.
