The 'Great Debate' - Spitfire vs BF109

[Crumpp]

I'm saying that the rates of divergence on the graphs you gave are miniscule

Again, Argue with the NACA, RAE, and Operating Notes....

The rates were significant enough to prompt a narrowing of the CG limits unless a bob-weight was installed.

Must not have been so insignificant, huh???

Nothing to argue, the RAE NACA and notes say it's slightly unstable and the graphs show it, and slight instability is just plain and simly 'no big deal'.

MkI's and MkII's did 'not' have the bob weight or a CoG revision, why they bothered in the MkV is debateable.
