I just did a quick test on these 2 planes in m4.101. map Smolensk.
what I got.
109G6 late
Rad close, 110% power, auto PP, hit 630km/h. but get engine overheat quickly. this perfectly matches IL-2 compare.
Rad 30%, 103% power, auto PP, 603km/h. engine can run without overheat till fuel tank dry. But according to IL-2 compare. G6 should get 607km/h @100% power.
La5FN
Rad close, 110% power, it can get 634km/h and no overheat at all. according to IL-2 compare, La5FN 's max speed should be 625km/h @7000m instead.
so actually L5FN has 31km/h advantage @ this altitude.besides I can feel that its acceleration is much better than G6.
La5F
Rad close, 110% power, it can get 613km/h and no overheat at all.
seems everything is VVS's favour, even under the desk.
