Just got these vintage 1/12 GP & EP racing car from Yahoo Japan.
In 1973-74, Jerobee, a company based in Washington State, created their 1/12 nitro car using a Cox .049 engine. Several aftermarket companies created parts for this car including clear Lexan bodies, heat sinks, and larger fuel tanks. This scale evolved into 1/12 scale electric racing when Associated Electrics created the RC12E in 1976-77. Jerobee became Jomac and created their own electric kit.
