Ambrosini SAI.2
The Ambrosini SAI.2 was a light monoplane built in Italy in 1934. Like the SAI.1, it was designed to participate in the Avioraduno [del Littorio] rally of 1935. Compared with that aircraft, the SAI.2's wing area was only 1.4 m2 less, but the reduction in drag as a result of the monoplane configuration versus that of a biplane resulted in a top speed 20 km/h higher. Both aircraft used the same engine type.
Despite the similarity in designation, the subsequent SAI.2S was a completely unrelated design.
