Macchi Castoldi MC-72

Macchi Castoldi MC-72

The Macchi Castoldi MC-72 flew to become the fastest propeller driven sea plane ever on October 23, 1934, with the still standing record speed of 440.68 mph.

In 1928 Macchi Aeronautica hired the talented young designer Giovanni Diliberto to work with Mario Castoldi in their design department. The Macchi Castoldi MC-72 became their design project for the company, first as a racer and eventually as a world record achiever.

The twin engine design incorporated into the Macchi Castoldi MC-72 was actually the second project engineered by Diliberto. The first was a 1/4 scale prototype of the design concept, simply a smaller version of what was to become the MC-72. The engine arrangement may seem unusual by today's standards, but worked surprisingly well. Castoldi praised Diliberto for his resourcefulness.

Two Fiat V-12 engines were linked together, one behind the other. A shaft from the rear engine ran through the front engine and on through it's hollow drive shaft to power the front propeller in one direction. The front engine powered the rear propeller in the opposite direction.

While the aircraft could be a handfull for novice pilots, more experienced pilots praised the Macchi Castoldi MC-72 for its speed, responsiveness, and directional stability. The Macchi Castoldi MC-72 remains a winner to this date.
