Development

Developed originally as the Porterfield Zephyr a light-weight version of the earlier Model 35 Flyabout for use a pilot trainer. Powered by a 40hp (30kW) engine it was later re-designated the Porterfield CP-40. To improve performance the engine was replaced with a 50hp (47kW) Continental A50-4 engine and re-designated the CP-50 Collegiate. It was a braced high-wing monoplane with a tailskid fixed landing gear. Total production was about 400 when production stopped in 1941 at the start of American involvement in the Second World War. A number of variants were produced with different engine installations.
