F. Giulli Ambrosini SS4.zip 2024-05-03

Yes, is a canard fighter! The first one to fly. And one of the first with a retractable nosewheel undercarriage, the single-seat S.S.4 designed by Ing Sergio Stefanutti and built by the Societa Aeronautica Italiana Ing A Ambrosini was among the most innovative warplanes of its time. Of all-metal construction and powered by a 960hp liquid-cooled Isotta-Fraschini Asso XI R.C.40 engine driving a threebladed variable-pitch pusher propeller, the S.S.4 had a proposed armament of one 30mm and twin 20mm cannon. Defective construction causes an aileron separation at the second flight.
