The power-to-weight ratio achieved by this engine, inclusive of the water in the cylinder jackets and tubing, the residual oil, the starter apparatus and the 220:, was present in its design. It had been determined that the prior aircraft's basic configuration, which was built around a central hull, while affording great stability upon the water, would unavoidably present a great obstacle to penetration and thus was substituted for a pair of 327:
The M.39 was specifically built to compete for the 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

Four days later, on 17 November 1926, de Bernardi used MM.76 to achieve a new world speed record of 416.618 kilometres per hour (258.874 mph) over a 3 kilometres (1.9 mi) course at Hampton Roads.
