Originally designed by Jack Rose in 1929, the Rose Parrakeet (yes, that is the accurate spelling for the aircraft) is a single place small bi-plane, with a distinctive elliptical profile. It uses a classic wood truss rib, spruce spar wing construction with a fabric covered steel tube fuselage and tail surfaces. It was first certified for commercial production in 1935. The Model A-1 originally carried a 37hp Continental A-40-3 engine. Later models used Scott 40 hp, Menasco 50 hp and Franklin 50 & 60 hp engines. Model A-4 was powered by Continental A-65 & A-85 fuel injected engines. Some of the original Rose Parrakeet airplanes from the 1930s are still flying.
