I think that there may be two separate discussions in progress here.  When
you mention stalling, Tony, you are speaking specifically of a wing stall,
rather than not having lift at all.  They are two different things.

I know of one Russian prop stunt plane that had so much prop force that it
could literally hover using its prop.  Not to mention that many fighter jets
will not stall going straight up unless the throttle is low (for going
straight up, less than 90% counts as low) but by that point, the wings are
no longer causing any lift, and therefore are stalled, while the aircraft
clearly continues to have lift, and is therefore not stalled.

The other guy (sorry forget the name and it's waaayyyy back in my PIC box)
who was talking about all the different factors was, I think, talking more
about when the aircraft would cease to gain lift at all.

What I'm trying to say is that a wing can stall and the aircraft can
continue on un-stalled (though if the aircraft is stalled, I think you're
almost guaranteed to have all wings stalled).  It depends on all the factors
originally mentioned.  If you've built a model jet fighter, and it can climb
straight up, chances are that if you punch the throttle, you'll never stall
the little beggar, though the wings may only be serving as fins at that
point.
