I don't know why I never noticed this before , probably because I was so busy trying to deal with everything else in IL-2.
I'm pretty impressed with IL-2's flight dynamics. It just seems like it has solved some issues that MS sims have never resolved.
Finally, I can ease an aircraft up into a gentle climb, cut the the power, hold the nose gently up, and start a ruddered turn while crossing the aileron control the opposite direction to hold the wings level, (the classic.... You're asking for it... spin setup!) and hey! presto! a spin ensues.
No spiral dives, no wierd stuff, just a nice spin with classic recovery behaviour..... Very Nice!
I also love the high speed stall characteristics, where you get a radical wing drop when that inner wing loses it's grip due to excess angle of attack during a high G turn in Combat situations, it really bites when that ME109 is on yer six!
