Stability and Control characteristics of the Early Mark Spitfires

[bongodriver]

It's unstable unless the CG is in the forward position.

Which is pretty much what I said

it only would have happened when the CoG was at the point it created the 'slight' instability i.e. with a full fuel tank

A full fuel tank is what makes the CoG move back, as the fuel empties the CoG shifts forward and the aircraft becomes more stable, it's got nothing to do with fanboyism, it's just plain and simple facts, I do CoG calculations as part of my day job remember.

This thread has devolved into fanboys re-interpreting the presented evidence into "merely a slight" instability because their egos can't handle it

No the pilot's notes also say it is 'slightly' unstable
