Fly it awhile and you'll learn how to use their sheer excitement against them. Or for the ones that think they have an easy target... you can leave them baffled.
Oh, I've been baffled/frustrated by '38's plenty while flying all sorts of birds... A6M5's, Spits of all flavor, KI-84's and Niks, especially making the mistake of trying to turn with a '38 more than 270 degrees while in a 190D.... can't turn, can't run.... only lived to get a kill in one of those deals once, and died plenty. It always seems to be the high 38 that dances on my head and I can never get co-alt/co-E. Totally defensive. When I do land a few rounds the 38 just soaks em up.
I love the 38, I just have aircraft A.D.D - I can't seem to pick one ride and stick to it!
