Do the flight models actually work?

Apart from CEM I've got all the realism settings checked. Stall, spin etc.
Flying the Me110 I chopped the throttles, gear and flaps down, hauled back on the stick and.....well not a lot happened. The aircraft just settled into a nice leisurely controlled decent.

Flying the Spitfire and Hurricane there is no stall warning. Just a metal wrenching kind of sound, a bit of floppiness and then stall out. Where's the buffet and warning prior to stall so characteristic of these aircraft?
