I agree with Karnak. The Spit14 is indeed, a different type of plane than other Spitfires - that much we all tend to understand. However, the feel and handle is so radically different that its almost a dismaying experience to fly it.. Many small features have been changed with the introduction of the Gryf. engine, but just what is it exactly that causes the Spit14 to wallow like the pig it is, and not the other Spitfires?
For as long as I can remember I've been in 109s, and frankly, any 109 is easier to handle than the Spit14. There was a time when the 109s were frustratingly sensitive to roll axis destabilization during high AoA maneuvers - this has been corrected with the recent FM adjustments and slight increase in flap usage speeds. However, the Spit14 was always, and still is, extremely prone to roll axis destabilization - the phenomenon which causes snap-rolls.
As a matter of fact, the Spit14 is easier to cause a snap-roll in than a 190.
When a certain amount stick deflection is suddenly applied just enough to enter the opening stages of accelerated stalls, most planes start buffeting, and then after the stall has progressed enough to deterr controlled flight one wing droops down. The 109s, handle extremely well in these situations. Maybe its because of the leading edge slats, but they are extremely resistant to sudden stall behaviors that has no warning. It wasn't always like this, but the recent FM change has given the 109s that much stability. In the case of the 190s, they have that 'snap-roll' behavior. Without much buffeting, as soon as the AoA crosses the stall boundary it suddenly stalls, drooping one wing.
Interestingly, the Spit14 behaves the same as the 190s. What's more interesting, is all the other Spitfires have a much more benign behavior that shows considerable amount of threshold from the first signs of buffeting until one wing starts drooping. You can drag the plane into a wild bull ride rodeo of a 360 turn and the plane will still hang on through it. All the other Spitfires do this - except the Spit14.
So why is this happening? Is the Gryffin engine that much hostile to the flight characteristic of the plane? Does the elongated nose/tail change so much of the airflow as to make it behave it like a 190 than a Spitfire?
