From 28-29 April 1948, Leonardo Bonzi and Maner Lualdi established a distance record for aircraft in this class, flying from Campoformido, Italy to Massawa, Eritrea - 4,650 km (2,900 miles) without stopover. On January 10, 1949, on board the same aircraft, now christened Angelo dei Bimbi, they headed for Dakar in an attempt to reach South America. After having overcome the opposition of the French authorities, they took off from Yoff on January 29, 1949, dispensing with radio and parachutes to be able to load 800 litres (176 imp gal, 211 us gal) of fuel. Seventeen hours later, they were in Parnaiba, Brazil. By the end of a triumphal tour through Brazil, Uruguay and Argentina, they had collected 500 million lire from the Italian community living in these countries to contribute to the economic restarting of Italy. Their plane I-ASSI is preserved today at the Museum Romeo Esparto of Milan-Arese.
A two-seater version powered by a de Havilland Gipsy Major of 120 kW (160 hp) was offered to the AMI as a trainer. The AMI were not interested, but a few aircraft were built as the S.1002 Trasimeno for aeroclubs.
