Ah - it's interesting that you specifically mention the nose-down behaviour because I believe some of the developers have been looking in to this already and this may be another example of a suspected problem. Incidentally, changing the roll rate shouldn't affect the other characteristics so I can increase that quickly and easily if that's the general consensus... If you're trying to use Alexis' A-10 tarball with 0.9.9 FG and not cvs you could try changing the wing incidence to positive instead of negative - that should give the same characteristics as with using cvs FG.
