Talk to Toad in a Val, Stiggie in a Stuka. Hell, I've kilt p40s and spits in both, and I suck in Warbirds. If they are stupid, and get down with you, or you are lucky in the rear, they die.
This is in no way an endorsement of the WW2OL FM, just a refutation that the Stuka in particular, and slow planes in general, are EZ meat.
