Tether cars are often small (less than 1 meter in length), powered by a non-radio controlled model aeroplane engine (two stroke, glow plug, piston liner, etc.
[2] Tether cars were developed beginning in the 1920s–1930s and still are built, raced and collected today.
First made by hobby craftsmen, tether cars were later produced in small numbers by commercial manufacturers such as Dooling Brothers (California), Dick McCoy (Duro-Matic Products), Garold Frymire (Fryco Engineering) BB Korn, and many others.
Original examples of the early cars, made from 1930s to the 1960s, are avidly collected today and command prices in the thousands of dollars.
There are tracks in Australia (Brisbane and Sydney), New Zealand, Germany, Switzerland, Estonia, Ukraine, Russia, the United States, and other countries.
