Spitfire makes only 300 mph?

[Deadstick]

Hahaha, more Spitfans complaining because it is not über like in IL 2.

Actually, even though I mainly fly Blue, I agree. I found this in a nother thread :

Of course, the Spit I's in the game, both the standard and Ia are completely porked. Both have the dual speed props, which is not accurate. 100% of the Spit I's with De Havilland dual speed props were converted to De Havilland constant speed props, most by the end of the first week of July, the rest by the end of August. Plus all new models coming out of the factory had Rotol constant speed props factory installed.

I'm not saying it proves they are not modelled correctly, but if they have not even got the props right, what else is wrong?
