Located at the Springfield Airport in Springfield, Massachusetts, Granville Brothers Aircraft operated
from 1929 until bankruptcy in 1934. Brothers Zantford, Thomas, Robert, Mark and Edward built a total
of 24 aircraft.
With its 7-cylinder 110 HP Warner Scarab radial engine, the Gee Bee Model E is considered by many
golden era aircraft aficionados to be the definitive member of the Gee Bee Sportster family. A prominent
feature was its Townend Ring, the narrow-chord cowling ring fitted around the cylinders to reduce drag
and improve cooling.
Sadly, all four of the Model Es produced were eventually destroyed in crashes, including one which
was flown by Zantford Delbert "Granny" Granville who was killed in February 1934, attempting to land
after an engine failure, while trying to avoid people on the runway.
Two replica Gee Bee Model Es are known to have been built and flown; one may be seen on display in
McMinnville, Oregon at the Evergreen Aviation & Space Museum, home of the famous Spruce Goose.
This 1/5 scale balsa, light-ply and fiberglass RC model is designed to be flown with an electric power
system that has a rating of 400 to 600 Watts.
We invite you to enjoy the pride of ownership and the joy of flying
this beautiful model of the famous Gee Bee Model "E."
