well, that's exactly the problem: the wings are the biggest target when deflection shooting, which is almost 100% the case in dogfighting against decent pilots. make one plane's wings pop-off even when only lightly touched, and make the other plane's wings resits to a meteorite fall.. and there you go.. a balanced fight
as for the rest.. may I laugh a little?
- flying straight/shallow climb -> the spits will get closer to you before you'll finish to say "bummer!"
- neg-G and dive -> the spits will outdive you before you'll finish to say "bummer!"
- neg-G, dive and roll -> guess what? read above..
- spiral climb -> need I quote again from the first point above? guess not..
and remember, everything of the above with planes having approximately same energy. if the spit has more, then you'd better say your prayer..
and these were supposed to be 109's "hardware" strongest points.. if you'll go into a turn fight with a spit, then you deserve your funerary stele.
yet, I'm not the best blue pilot around, and my viewpoint might be slightly biased.
that's why I would only support historical data FM changes backed up by pilots constantly flying on both sides, or by the pilots from the other side (reds supporting blue FM changes, and viceversa).
and in the end, it is not about the machines, as it is about the people who flew them. the better pilot would win more often, no matter how crappy is the machine he's flying on
