Well, that's an interesting engine arrangement. (to put it mildly)
Hi Dave,
Yes, as explained to Indrek:
"Macchi-Castoldi MC-72 Fiat AS6 engine; dual V-12, 3100 total HP,
each engine drives one very course, fixed-pitch prop 440.729 mph in
1934. Class record still stands. Why contra-prop? Supermarine S6B w/
2650 HP on single prop overloaded one float by 32% on takeoff due to
torque."
Regards,
Ri奄rdo
