IMO the Airacobras in this game (like P-51Ds, all F4us, and some other planes) lack a number of vices in their handling, making them ... shall we say "more effective" than historically true. The plane is totally rock-stable even in the most off-angle stalls. I've almost never spun one out, despite numerous historical tales of instability.
One thing I think IL2 got better than AH, and that's a VERY short list of things!
