Hiya Cats,
As it happens, I and another ATAG member performed some time to climb tests up to 10,000ft
pre-patch, and found that the 2-speed prop Spit matched the 87 octane figs quite well , but the CSP prop Spit 'MkIa' in the game had exactly the same rate of climb as the 2-speed prop version (bearing in mind the CSP on the Ia came out in a patch last year).
The Spit II and Hurri Rotol also matched published time to climb data very well too, again pre-patch.
This was all using the optimum climb speeds and rpm stated in the pilot's note etc, or available from various websites.
Obviously human error came into optimising the climb rates for all of them, as opposed to the computer programme which tests the game's flight models, but then again the real ones weren't flown by computers either.
Time to climb is a great method of testing in my opinion and together with the top speed figures at various altitudes already posted by others would give us a pretty good all round picture.
