If you've actually applied this perhaps you'd like to quote a few popular aeroplane types and their take-off, cruise and display prop rpm figures to give people an idea of the speeds they should use?

Rob, All I know is light aeroplanes the other stuff I just photograph and thought to do a bit of maths to help people.
Light aeroplane C152:-
Take off 2500rpm
Cruise 2150 - 2250rpm
Landing 1000-1500 depending on how your approach went!
I understand you are close to the Shuttleworth trust could you please provide an indication of warbird prop rpm, maybe you know someone who can provide the answer. I know warbirds have reduction gearboxes but what ratio?
