I do think that most of German planes fly faster than should. Real picture was that only earlier and later only Hungarian production planes were able to achive the manufacture specifications in a series using German quality of the fuel...
That tell Lufwaffe pilots in recals and speeches with them (30 km/h slowly is a middle digit of their recalls)
And also we don't model end-war rising the quality of Russian fuel ...
Bf-109K4 fly now by the German manufacture specifications which we have from known for community historian collection of German aviation docs.
Now you have two models with DB-605DB 1.8 ata and DB-605DC 1.98 Ata.
Climb was decreased to realistic values (as well as decreased for the La- series even more)
However late Yaks still flyes not so good as it should (from the words of pilot who fly Yak now)
So speeches about Oleg's no interest are wrong.
Youn even don't know how is hard to find NON CORRECTED by some oth other in time _real_ docs.
I also recommned to read the original German document about the problems of DB-605DC 1,98 ata..... That was the whole list of problems... And if that is serial production this would means never use of 1,98 ata really. Just take it in account.
Finally... For your sure I'm really Russian born. However my whole family (as result also me in the end of branch) is a mix of English, German and less - Russian bloods.
Do you know my favirite aircraft of the WWII in technical aspects (cost/Engineering ideas terms) - this German plane FW-190. I think many here know this. However it doesn't measn that this plane will fly better all.
In terms of Sexy looking aircraft I like very much Mustang and less Yak-9U post war production. In the last case it doesn't means that I will model Yak-9U to the trials before manufacture speciafications. We model it with all the problems of aircraft of the first series. And still there isn't present the series of 1945 winter-spring that almost hadn't them and match manufacture specifications... Just try to find them that to have an image of what I told here Smile
Same: there is still not present Yak-3 VK-107A of both variants that met Germans in the last months of the war...
I think you should be more thinking that to post what you posted. I told here just 10% what I can tell....
