Stability and Control characteristics of the Early Mark Spitfires

[Crumpp]

Instead of just being smart and making rolleyes how about proving, with documentation,

This is the second or third time in this same thread the same argument has arisen.

The instability existed in all early mark Spitfires at normal and aft CG until it was fixed with the inertial weights.

It is a function of the tail design and elevator, static margin, and fuselage length.

The Operating Notes are full of warnings about it. It was not limited to one propeller or a specific load.

It was at NORMAL and AFT cg.

NORMAL....

Noun: The usual, average, or typical state or condition.

Your whole premise of the Constant Speed Propellers being the "most adverse condition" is just plain wrong.

Which do you think is heavier? A three bladed CSP or a two blade fixed pitch wooden propeller? The correct answer is the CSP.

What do you think happens to the CG when you add weight to the front of the aircraft? Do you think it shifts forward or back?
