I think what really is lacking is a serious counter-argument (with circumstantial evidence/docs) to gaston's story.
His 'evidence' is purely documentary and he is definitely well read on the topic, but he provides a really convincing argument that no one here can really refute (it's like religion)
What I can say, IL2 gamewise, is that Oleg's modelling does come close to what Gaston's hypothesis - In a FW190 I can outturn a spit in a right turn at stall speed - I have done it online many a time..
When I get my pedals working again.. you're all dead meat
