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

[raaaid]

i found out long ago that if you turn a 109 to the limit eventually you reach 200 kph and starts turning very slow

on the other hand to sustained turn the spit the best is fly it at the stall limit that is as slow as posible

why is this?

anybody?

maybe the slats in the 109 are actually a disadvantage?

No just the fm is very bad ATM spits can turn like a biplane!!!!

Generally slats cause more drag and effect also higher energy bleeding but other hand allows to get higher angle of attack - good for deflection shoting. Spit other hand has elipitical wing desing which reduced induced drag which is important at slow speed and high angle of attack and with lower wings loading it casue less energy bleeding in turns then 109.

I found that slats in CLoD 109 dont work also like should. It is open too late - at too low speed - ab. 150 km/h where it should open at 180 km/h - in level flight with idle power. I think it open also at too high angle of atack - it should open earlier.

Also slats should casue gentle stall in 109 and easy recover in stall or spin.

What we need is the Dynamic Stall in the FM, I think that those strange turns that some planes do (not only the Spit) without lose control is due to the lack of this Dynamic Stall, they reached the point where this stall should start but its not modeled in the FM.

Acctualy the 109 stall is not easy to recover in CloD. In the old IL2 when the plane started to stall was only necessary to neutralize the controls and the 109 recovers alone. In CloD the 109 stalls and enter in a flat spin very fast and it is very difficult to recover. This is not historically accurate i guess. The 109 had a gentle stall. Someone with better english have to report this in the bugtracker.

That is the standard stall system, Dynamic Stall is a different type of stall.

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)

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?
