The Ambrosini SAI.3 was a two-seat Italian touring airplane first flown in 1937. It was a low-wing monoplane with a graceful elliptical wing and fixed tailwheel undercarriage. Customers could choose between enclosed or open cockpits and between an inline Alfa Romeo 115 engine or a radial Fiat A.50. A revised version was marketed as the SAI.3S with a smaller-chord wing and a Siemens-Halske Sh 14 radial engine this offering far superior performance to the original SAI.3 design.
