I don't think the flight characteristics of models directly correlate to actual aircraft. Compromises are made. For example, look at the effect of the elevator trim on a model of a particular aircraft compared to the effect on a real aircraft. Almost always, the model effect is "scaled up" significantly. This can have real interesting results if one uses this as the blueprint for a computerized flight model.
That being said, I have not really tested the vertical stalling capabilities of the various aircraft here. I break out in hives anytime I'm in the MA and my airspeed gets near zero. Interestingly, the hives form a "bullseye" symbol right in the middle of my back in this condition. So, it's not one of those things I really worry about.
I can see, however, that this concerns you. So, why don't you go through the plane set with a standardized test, record what you find and post the results here for discussion? I'm sure we could then get Pyro to comment.
I look forward to your post!
