The C-8 Eightster was a single-engine airliner developed by Granville Brothers Aircraft that did not go into production.[1]
Design and development
The C-8 was an uncompleted design for a single-engine airliner, a wire-braced low-wing monoplane with conventional landing gear and a radial engine. Entry was from a small left rear door in the fuselage. Passenger visibility came from three semi-circular windows along each side. The main landing gear was faired similar to the Gee-Bee racers.
The Granville brothers also designed a series of sportster derivatives, including the C-4 Fourster and C-6 Sixster. The C-8 was the only one to be constructed, being partially completed by the time the company went into liquidation.
