Good Day, and welcome to our site dedicated to the building, racing, and promoting the sport of Formula 1 Air Racing! Take a look through and come back often as we will be updating as things happen and progress throughout the build!
The Snoshoo SR-1
We are building our aircraft for both "racing" and "sport" meaning that we will race the aircraft then with a little reconfiguration, convert to sport and be able to fly the aircraft cross country to advertise and promote our Team, Sponsors, and to showcase the aircraft at various venues. However, our core will be a "hard-core" racer, the Snoshoo SR-1.
The design uses conventional, welded 4130 steel tubing for the fuselage (truss) structure, unquestionably the best material in terms of durability, crashworthiness, cost, ease of incorporating design changes, reparability and its efficiency in overall strength-to-weight.
The wing of the SR-1 are all-wood construction. Aircraft-quality Sitka spruce is used for the laminated spars. The tail assembly will be made up of light weight carbon fiber.
The engine used for Formula 1 Air Racing is a Continental O-200. This is the same engine that powers the Cessna 150. However the speeds reached are much higher than the 150! The propeller is a 2 bladed and can be either carbon fiber or wood.
