The real plane
The Macchi Castoldi MC-72 flew to become the fastest propeller driven
sea plane ever on October 23, 1933, with the still standing record speed of
709.2 km/h ( 440.68 mph.)
In 1928 Macchi Aeronautica start work with G. Diliberto and M. Castoldi
on the Macchi Castoldi MC-72, at that date the most revolutionary project
for a Schneider Cup racer and world record achiever.
The MC-72 incorporated a twin engine design, two Fiat V-12 engines
linked together one behind the other, powering two counter-rotating
propellers. An arrangement that worked surprisingly well,
because this
design advantage is that counter-rotating propellers balance the effects of
torque, making easier the control of the plane in every flight condition.
The aircraft could be a hand full for novice pilots and more experienced
pilots praised the MC-72 for its speed, responsiveness, and directional
stability.
The Macchi Castoldi MC-72 remains a winner to this date.
