This well-known company in the airplane model business went into slot car racing in a big way in 1964, producing beautiful and well engineered kits. By 1965, a second series was issued featuring improved motors and new body styles. In 1966, K&B joined the busy crowd of the vacuum formed body RTR cars, their most famous (and elusive) being their own version of the Batmobile that featured a functional disc brake and a roof light. K&B was a victim of the 1968 collapse but survived as a model airplane engine manufacturer.
