Hmm, Oleg stated too, that he is really producing a FLIGH SIMULATOR, not FLIGHT SPECULATOR, like AH is in many cases, like speculating stick forces pilot is able to pull in a dive. He knows very well the pros and cons of that.
He has stated, that all of their FM:s corresponds to the data that he has gathered from various Russian sources, like Tsagi and NVII VS. Im sure, that he has looked the NACA charts also, but Russian source should be superior to Allied, since Russia did have good amounts of same German aircraft type available for testing.
You dont start this kind of project just with reading couple of Rommels diaries.
Il-2 FM isnt based on tables, like AH is for instance, so some things, like max speed and max roll on different altitudes do not fall perfectly in chart data.
Il-2 box will have all of the flight performance data used in their sim printed. That thing alone is enough for me to buy that box, yet alone i get flight sim with best ever evinroment and unique touch of flight modeling aside. If Il-2 has somehow biased roll rates, i dont give a damn. Theres other things that AH simulates poorly in comparison, so that will bring fresh ideas in flightsim scene.
We already have AH, why do you want another copy of that?
I love both sims. Im not anyway blind fanboy of Oleg, but i very much like the fact, that he takes time listening the users complaints in BB. Also, i love the fact that this game is made by Russians, so it will be finished product, not some MS buggy crap.
Buy it or not, i will.
