No joke: 248mph Hurricane dh5-20, 230mph Spit... what on earth is going on??

I think you've missed the point dutch... I am talking about in game Spit 1 vs 2a and more to the point... the dh5-20 is faster than the Spit 2a.

Oh, sorry me old chum, I probably did (few beers you know )

Yep we all know there are top speed issues with all the models, but the difference between the top speed of the props should be there. The DH prop should be faster on the level than the CSPs. Whether the difference in values is correct is another issue.

I'd have to have a bash at the DH5-20 v IIa myself to see what you're driving at perhaps.

Oh god.....more testing...........great...........

Spitfire performance comparisons fixed pitch 2 blade v 2 speed v constant speed props:




NB: The wooden ROTOL CSP is almost the same as the type fitted to the Spitfire IIa (N3171 was part of a batch of Spitfire Is in the N3--- series fitted with Rotol CSP and UHF radios and used operationally Feb - May 1940 by 54 and 66 Sqns)





In general the speed differences between various prop types seem to be reasonably well modeled for CLOD.

Just did a quick test, 17000ft with boost and 50% rads
Spit 1 270mph
Spit 1a 240mph
Spit 1a 100oct 240mph (blown engine)
Spit 11a 225mph
Hurri DH5-20 255mph
Hurri mk1 100oct 220mph (blown engine)
Hurri Rotol 245mph
conclusion :- 2 speed prop is faster on both types, 100oct is fragile,
