Developed as an all-metal version of the P.57 Fachiro, the prototype was designated the P.64 Fachiro III and first flew on 2 April 1965. Improvements were made to the design, mainly to the rear fuselage to fit a panoramic rear window, and now renamed the P.64B Oscar B it first flew in 1967. Also known as the Oscar 180 powered by a 180 hp Lycoming O-360-A1A piston engine, a 200 hp version (with a Lycoming O-360-A1B engine) was known as the Oscar-200. Twenty-one aircraft were delivered to South Africa and assembled by AFIC (Pty) Limited and marketed as the AFIC RSA 200 Falcon.

In January 1976 the company flew a new fully aerobatic version, the P.66C Charlie, and 96 were built, mainly for the Aero Club d'Italia.
