Ambrosini S.A.I.3

Designed as a two-seat light training and touring monoplane, the Ambrosini S.A.I.3 had long-span elliptical wings, a deep rear fuselage and a fixed 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. 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. The more powerful Alfa Romeo-engined model had superior performance, despite a maximum take-off weight increase by 40kg to 830kg; maximum speed rose to 230km/h, service ceiling to 5200m and range to 680km.
