IL2 doesn't have this, but neither does DCS, strangely enough for a 'study sim'.

But IL2 does model yaw stalling sooo much better than DCS - they were very upset when I told them so. DCS does seem lack a few FMs, but generally the feel is smoother than IL2 and does feel more like a real plane.
The engine startup procedures are nice in DCS and one has to be carefull with certain items as you could blow them (Engine starter).
IF TD can implement these things into IL2, DCS would take a backseat as it still lacks a lot wrt gameplay.
