Schneider Trophy; accordingly, its design had specialised features to aid it in this exact purpose. As the course circuit required left turns, the left wing of the aircraft had a slightly greater

wing, which was situated underneath the fuselage, was rigidly braced using steel cables. One feature of particular note about these wings, which were composed of wood, was that two-thirds of the wing's upper surfaces functioned as low drag

Macchi produced two versions of the M.39, a trainer version and a racer. The trainer version had an increased wingspan of 10.23 metres (33ft 7in) -compared to the 9.26m (30ft 4.5in) of the racers- and was powered by a 447-kilowatt
