Rotec R2800
The Rotec R2800 is a seven-cylinder 110 hp radial engine built by Rotec Aerosport Pty Ltd in Australia. The R2800 was Rotec's first (and only) engine offering when they first opened their doors in 2000. In 2005, Rotec released a more powerful variant, the Rotec R3600 adding two more cylinders for a total of nine and increasing the rated horsepower to 150. This engine and its larger cousin are frequently used on World War I aircraft, both vintage and modern reproductions. Some notable repro WW I aircraft this engine has been used in are the Fokker Triplane, Sopwith Camel and the Nieuport 17. Other experimental / homebuilt aircraft have also been fitted with the Rotec 2800, including the Kitfox Model 7; a popular kit aircraft with over 5,000 examples of all variants completed. It is unknown how many Kitfox aircraft are equipped with the Rotec 2800 engine.[1]
These engines are not limited to only aircraft applications as JRL Cycles has converted an R2800 for use in a motorcycle.
