Model #KV-53


The BatRok was introduced in 1967 by Centuri Engineering Company. It was designed by Ron Maggiano while he as a high school student in Scottsdale, Arizona. Inspired by the hit television series Batman which premiered in 1966, Ron entered his original design in a model rocket competition sponsored by Centuri and won a $25.00 gift certificate. The original BatRok was slightly smaller but had the distinctive “Bat-Fins” and payload compartment. Although the BatRok did not make it into a catalog, it is an outstanding example of the innovativeness of early modelers. The BatRok was Centuri #KB-8 and was introduced with a price of $1.95.
