The Gee Bee Model Y Senior Sportster was one of the famous “Golden Age” racers created by 

Granville Brothers Aircraft in the early 1930s.  It was a low-wing, strut-and-wire-braced 
monoplane with open cockpits. To a great extent, it was an enlarged, two-seat version of the 
single-seat Sportster. Only two were ever built; both were unfortunately destroyed in accidents. 

This radio-controlled almost-ready-to-fly (ARF) 27% sport-

scale model is based on the full-scale Gee Bee Model Y Senior 
Sportster. It comes 99% preassembled by our factory, includes 
a prepainted fiberglass cowl and wheel pants, and includes a 
spring-loaded tail wheel to aid in ground handling. 

We invite you to enjoy the pride of ownership and the joy of flying this beautiful ARF 
sport-scale model aircraft.
