The cars in this category were initially introduced by Playing Mantis under the Johnny Lightning product line. The initial release featured a reproduction Tjet body on pullback chassis. Later releases come on a reproduction Tuff-Ones chassis. These chassis have several generations behind them and are showing steady improvement in design and quality. An inexpensive and affordable addition to the hobby. If you want the challenge of the original Aurora Tjet racing then these are for you. Or you can join the hundreds that just enjoy collecting them.
