Designed as a two-seat light training and touring low-wing monoplane, the Ambrosini S.A.I.3 was an extremely graceful aircraft, with long-span elliptical wings, a deep rear fuselage and, unfortunately for the type's looks, a fixed and somewhat clumsy tailwheel type landing gear. The chosen powerplant was either a 63kW Fiat A.50 radial or 97kW Alfa Romeo A.110 inverted inline piston engine, the latter enclosed within a close cowling of nice proportions. Small batches of the S.A.I.3 were built, some of them with an enclosed cabin in place of the more common tandem open cockpits. Not surprisingly, the more powerful Alfa Romeo-engined model had much superior performance, despite a maximum take-off weight increased by 40kg to 830kg; maximum speed rose to 230km/h, service ceiling to 5200m and range to 680km.
