The Porterfield Model 35 Flyabout was an American two-seat cabin monoplane built by the Porterfield Aircraft Corporation of Kansas City.


The aircraft was designed by Noel Hockaday and was built by students at the Wyandotte High School as the Wyandotte Pup. Porterfield Aircraft recognised the potential of the aircraft design and bought the design rights and also the services of Hockaday as works manager and designer. The Pup was developed to appear in 1935 as the Porterfield Model 35 Flyabout a braced high-wing-monoplane. It had a fixed tailskid landing gear and room for two. It was originally powered by a 60 hp (45 kW) LeBlond 5D radial engine. Variants later appeared with different engine installations and a deluxe model the De Luxe Sport. Over 240 aircraft were built.
