Yesterday on Atag server I had a hurri on my tail which pursued me over the whole channel flying low (so not a hurri with energy advantage). I could not loose it in my 109 even though I was at its ingame max speed of something between 450-460 kph (at least my extensive offline tests yielded this as the implemented max speed for the 109 whatever type). Sorry, but this is definitely not historic right now.

But to my knowledge they will anyhow overhaul the FM completely so we simply have to wait with what they come up with in the future and then see again.

I just want historic performance. Old IL2 was not that bad - at least it got the overall tendencies right.
