British FM killing the fun of the game for allied pilots.

[Crumpp]

We're back to using a MK V test to change the FM for a MK I/II again are we...?

All the early mark spitfires, until fixed with inertial elevator systems had the instability at aft and normal CG as tested by the RAE.

The NACA gives us the more detailed measurement and insight into specific behaviors. Unfortunately, the RAE did not have the level of sophistication or equipment at the NACA disposal.

All we can prove is that the RAE said the early marks were unstable at aft and normal CG, we have one measurement of stick forces, stability diagrams for long period oscillation.

We can prove that the basic stability characteristics in the game are not representative of the real aircraft.

Technically, you are right though, we don't have the level of detail provided by the NACA reports from the RAE and none of the NACA material is about the early Mark Spitfires.

Maybe your right and we should not model the stalling characteristics of the Mark V either.

Just go with what the Spitfire Mark I and II Operating Notes say about the sudden, violent, stall that results in immediate spin if not corrected.
