why the spit turns most effectively at the limit edge and the 109 doesnt

[Widow17]

i think spits smallest and fastest turn are at about same speed, 109 samllest turn is at a slower speed than its fastest, thats why spits tend to be called easier as you dont have to watch geometrics as much (know when priority drifts to smaller and slower or faster and wider turn)

Dynamic stall

A nice video, the reproduction of the vortex produced by the Dynamic Stall

From seeing the cfm clip: That is for me the definition of stall: the breakdown of flow on top of the wing. I do not know of any other definition of stall.

So can somebody explain to me what's so special about dynamic stall?

From http://en.wikipedia.org/wiki/Stall_%28flight%29

Dynamic stall is a non-linear unsteady aerodynamic effect that occurs when airfoils rapidly change the angle of attack. The rapid change can cause a strong vortex to be shed from the leading edge of the aerofoil, and travel backwards above the wing. The vortex, containing high-velocity airflows, briefly increases the lift produced by the wing. As soon as it passes behind the trailing edge, however, the lift reduces dramatically, and the wing is in normal stall
