I admit, I don’t understand the fascination with post-stall/spin simulation. As stated, the objective in combat and civilian flight is usually to avoid those areas because it’s dangerous and (in combat) ineffective. If a plane is designed for the express purpose of exploring those areas while offering little to nothing in the areas I am concerned with (getting to places and shooting things), then the plane itself does not interest me.
I would just as gladly avoid ever stalling or spinning in any sim and not worry about whether it’s doing it right or not.
