Geez, this is a question that requires a pie chart and several graphs for sure.
My bad luck bird is probably the Spixteen oddly enough. I can kill and live way better in pretty well any Spit than I do in the XVI in a furball. Even the Spit I. I don't know why, I just seem to wind up in constant accelerated stalls in the thing and get dead.
My bad luck enemy bird is hands down the A6Ms. They should be virtually no threat when you fly the big, heavy fast stuff like P47s, F4Us, C205, and so forth. As long as I don't blow my E in their vicinity I should be safe from them, right? However it seems almost without fail that I will get into a situation where I have to get a little slower than I'd like for whatever reason. Then there seems to be a Zeke specific feature in the game that puts a big orange flashing circle around my plane saying 'WILEY BLEW HIS E, COME IN AND KILL HIM NOW IN HIS LOW SLOW P47!'
I then get out-accelerated and die.
