Stability and Control characteristics of the Early Mark Spitfires

[Crumpp]

As for the other qualities evaluated by NACA, be it good or bad, it sums up that there's nothing critical.

JtD, they flat out state the stick fixed longitudinal stability is unacceptable. That is the NACA, not me.

Why do you think bob-weights were added to the design to fix the longitudinal stability?

Because they just felt like changing something? Maybe they were bored and had nothing else to do?

Or maybe, just maybe, there was a real engineering issue with the longitudinal stability that required a real engineering solution? Nahhhh!!!
