Sorry, I am not that FM expert, but what is about turning speed at low speed.
Perhaps I remember wrong, but as I learned it, the graphs of spit vs 109 always showed the tendency, that the bf suddenly turns better than a spit at real slow speed. I even remwmber some graphs, that a 109 even could turn faster at some low speed, than a LA5. Were this graphs referring to the real life or to the old il2?
I also remember some flights in old il2, where I thought, that I pulled my F4 to the max, but a P38 turned with me. I know that this smy fault and my lack of flying skills at this time, so you should really ask yourself, if the other pilot was simply much better pilot than you!?!
Just to throw the big ???? of skill lack into the discussion of this case.
I do not want to blame anybody, bit just take it into account when argueing about fm.
What I got to hear from some skilled pilots and self named experts is the opposite of snapper. I heard thatthis should be okay so far, because bf109 had nearly no fm advantage left. They for sure say, that there are other things to be fixed, but I never heard anybody of them complaining as hard as snapper.
The bf is not uber! I am really looking forward to the implementation of fw190's WITH "kommandogeraet?", which will cause the focke to be uber in many condition. But that is another topic, but red pilots will argue about that as well.
