Question

Name the 3 fastest single piston engine, fixed gear airplane.?

Answer 1

The fixed gear part is complicating things. I guess it would have to be Schneider Trophy racing planes of the 1930's.

I'll go with :-

1934 - Macchi MC72 - 440.68mph (705kmh)

1931 - Supermarine S6B - 340 mph (547kmh)

1929 - Supermarine S6 - 328.6 mph (528kmh)

1927 - Supermarine S5 - 281.6 mph (453kmh)

1926 - Machi M39 - 246.5 mph (396.5kmh)

Answer 2
