Control response in Il-2 is very important and needs a lot of tweaking.
In my experience, curves between linear and quadratic for sliders give the cotrol response very close to the one in AH. For 190, that is. It will fly exactly as in AH, no bouncing whatsoever.
roll sliders - AH 100% all the way, Il-2 linear
pitch - AH linear, Il-2 linear or quadratic
yaw - AH linear, IL-2 linear
linear - 10,20,30,40,50...
quadratic - 1,4,9,16,25...
Still, it is very different from plane to plane and each type requires different slider setup, again, from my experience.
IMO, Il-2 offers many options with which you can tweak the game - from "arcade" to "too hard".
