What are you talking about???
The Hurricane abrupt turn as recorded by the NACA is stick fixed. The Spitfire abrupt turn as recorded by the NACA is stick fixed.
The RAE stability measurements for general stability characteristics are stick free.
In both the RAE and NACA measurements, the Spitfire was longitudinally unstable with unacceptable characteristics.
That is why they added the inertial elevator to fix the longitudinal instability.
What is the issue? Why is blatent fact so hard to understand?
All the smoke, mirrors, and baloney put out about "it is normal" and "all fighters of the day" acted like that is pure fantasy.
If there was not a problem, then they would not have fixed anything!!!
