Cox Thimble Drome Prop-Rod Air-Powered Car

This Prop-Rod car was one of the earliest models produced by L.M. Cox Manufacturing. For many years the models went by the trade name of Thimble Drome, but later were know simply as Cox models. It was featured in magazine advertisements as early as 1961 when it appeared in American Modeler. The Prop-Rod came it a Babe Bee .049 engine that had an inverted cylinder. It was designed to run either on a tether stretched along a sidewalk, on a tether mounted in the center of a circle (see video below), or it could just run free. These couple photos were captured from an eBay auction a while back. The Prop-Rod was a little over 12 inches long and 6 inches wide.
