Yes, but what do you need them for?

For having some deeper knowlodge of my weapons when flying combat missions offline and online. I love this flight sim, have been with it for years, and naturally want to know more about its contents. I am an ardent fan of IL2. (Besides, relevant historical data found on the internet are not exactly the same as those written in IL2-1946; for instance, it's said that in the sim all the A6Ms use the MG/FF cannon, whereas in real life A6M2 had Type-99 I, and A6M5 Type-99 II, these two cannons having very different muzzle velocities.)

Perhaps my questions concern some technical features of the sim that had better be kept away from public knowledge. I am not sure.

Type 99 I 20mm cannon was a copy of MG/FF cannon.
And Type 99 II 20mm cannon was a copy MG/FFL cannon.
Performance wise.

Last time i checked IL2compare, both are in IL2.
