... you are right Kapteeni, for those who want to learn about FMs there's this topic at SAS and especially for ACA-OF-ACES what Lutz (probably the one modder that has gone deepest into the game code, his job is to launch satellites ...) :
"One thing are parameters and the other thing is to see how they are processed by the soft. The fact that flight dynamics equations are "universal" is not an insurance that they are used and processed with the same (and logical) manner. As I have seen since a long time, IL2 code contains approximations (smaller or greater in certain cases) to perform the modelisation and to obtain a plane behaviour which stick in some points to the real one (when data are available).
Modelisation of atmosphere... is just a modelisation, modelisation of compressibility (specially M is greater than 0. is just a dream in IL2, modelisation of propellers is very strange, shape of polares, for all planes in IL2, are deducted from a single family (ie B17 and Me 109 ..) and so on...
That means, if you want to go in this way, you have to consider, not only the parameters but also the coding...
Infortunatly for you, in french, a link to our forum where some FAQ are discussed since a long time about IL2 flight dynamics. URL indicated in first or second post is out, but, end of november (I am not at this time in France), I will upload again a document where main parameters are explained."
the rest is here :

and Lutz's work (in French) here (ACE-OF-ACES I am pretty sure you're gonna like that 'cause it's stuffed with curves
)
