The Fw190F-8 was just outclassed by the P-39.
My sympathies on your demise (poor Focke Wulfs! Such a waste!), but the Fw190F-8 isn't that outclassed by the P-39Q.
Airacobra will out turn it 365 days of the year, and can dive superbly, but the FW is faster than it in all alts outside of 8-12k, where it's a tie, and has 2x the WEP. Any dogfighting would be a no-no, for sure, but you should still be able to disengage. Climb rates are fairly close, as well, especially if the P-39s have gondolas (which most screenshots I've seen with FSOs, they tend to be the majority).
I know, doesn't change the results, jus' sayin'!
