To improve performance the engine was replaced with a 50 hp (47 kW) Continental A50-4 engine and re-designated the CP-50 Collegiate. It is a braced high-wing monoplane with a tail skid fixed landing gear. The two bracing struts run in parallel from the bottom of the fuselage and the tailplane was fixed to the top of the rear fuselage. Due to the narrowness of the fuselage, particularly to the rear of the cabin, the type is nicknamed "Skinny Bird".

Production and operations

Total production had reached 476 when production ceased in 1942 at the start of American involvement in the Second World War. Over 100 Porterfields remained active with private pilot owners in the United States and other countries in 2001. A number of variants were produced with different engine installations, resulting in a series of model designations.
