After making some more analyz there is definitly something wrong.
Polars Clmax/AoA which i used before from Profili or other sources were not reliable beacuse there were for RC models and for small Reynolds numbers.
I rechecked charts which i got for some of these planes and i found that i made mistake and wrong read values from chart. Is it possible that developers of these game also made such mistake?
Here are their Clmax values:
1.462 - Pfalz D.IIIa
1.370 - Fokker D.VII
1.313 - Albatros D.V
Here are valuse which i read directly from charts ( for airfoils):
Plflaz -
Clmax - 0,78, AoA - 16 deg
Fokker -
Clmax - 0,67, AoA - 16 deg
Albatros -
Clmax- 0,68, AoA - 14 deg
SpadXIII -
Clmax- 0,52, AoA - 14 deg
They look somewhere very low but are quite possible.
