Dogfighting -does 4.11-4.12 patch address this?

I also play lots of QMB, usually against veteran skill level AI.

But, I found it quite easy to dodge the AI's head-on shots. Two methods:
1, shoot first. AI will be scared, and evades.
2, fly upside down, then roll back+evade. AI tries to calculate the deflection angle, but he is usually too late.
Besides immunity to G, and sniping you from great distances (mainly bombers), I dont think AI cheats at all. There are a few cheat planes, like La-5/7 or Yak-3-VK107, but they only have overmodeled FM. You can also cheat with these.

- Your tail scratched by a uber a.I. wingmen appeared in 0,0001 millisecond at your tail immediately just when you try to shoot an enemy in front of you.

I noticed similar in the IJA campaign. American planes cooperate extremely well, but it is manageable if you are careful. Strangely, I dont see anything similar with any other nations: german, soviet, japanese, etc. use "standard" AI tactics, wingmans dont help their leaders too much. Sometimes they just fly the opposite direction!
