The Trabant was built in Germany in the early 1960's. Carl Sedlmayr,Jr. purchased it and the patents, letting Chance build them. The Europeans continued to build them with Mack building the Hully Gully (a trabant with scenery and more flash). In the early 70's, Chance changed the ride again, adding the folding sides and theming some as Casinos. In the late 80's they came up with the Wipeout, changing the rim drive to hydraulic, and re-designing it completely.
