Il2 sturmovik original fight model was different?

The game has improved a lot since the beginning and yet there are still a lot of factors that aren't even modeled yet (It would be so nice to get, at least, roll axis inertia which was the reason the 109 had the wing guns removed - and why gunpods hurt it so much *but not in game*). And I still would like to see more realistic stalls across the board (for instance, P-39s with ammo were not difficult to recover from spins within the first three turns, to say nothing of how easy to prevent from spinning in the first place), but stalls are now easily the best they've ever been. The game is in no way a substitute for real flying but it's a heck of a lot cheaper and, regardless of the style of flight termination, one is free to go out to dinner immediately afterword with no thought of deductibles or co-pays.
