Just tried P40 in WOL for the first time and got pretty impressed with those .50 cals. They seem to light up engines easy and I was able to rip apart two 110's in no time, 3'rd one got me though . I kept manifold/rpm safe when in combat at 40/2900 and didn't have any engine issues. Thing is ... I got feeling that plane isn't much faster with combat setup then when using cruise setup 37/2600 if at all. Is that just me or ...? Also is mixture auto? It seems to set at 66% at takeoff but not sure how to use it. Tried various options but I didn't really see any difference except when being over 95% it would give me mixture warning, no matter what alt (flew mostly below 3k).
