On chapter five, talking about the "platform" it seems interesting how it would appear some of their fighters are modeled differently than in AHII. It indicates the 109 as having a "good" roll rate, and the spitfire having a "bad" roll rate. Definitely not the case in AHII (at least not in my experience).
Before anyone blasts me, I think AHII does have the best FM out there... I am merely pointing out some interesting discrepancies.
