Engines are too strong and reliable.

good tactic which works in multiplayer at least, would be to make a diving attack from above and behind.

Dive below the AI, and shoot him when you start zoom climbing, and then continue zooming up.

Adolf Galland used that tactic quite often in Battle of Britain.

Well overall I think such AI as it is now, is way much fun then before.
Before they were just speed junkies with bad accuracy, firing their guns allways off (unless a veteran or ace).

Even old campaigns are now way much intensive then before, and when I complete the hardest missions, I feel like I'm happy to be alive - just like reading Clostermann's or other reall ww2 pilots books. Feels intensive.
