I must admit, the more sensible AI is much more impressive, in my video you'll note that I have what I think is a LaGG (can't really ID it at that distance) curving in to attack at around 7:20 as I pass over the airfield at low altitude, I look forward and then I look back again just in time to see an explosion on the airfield. I can only presume that the LaGG tried to pull a sharp turn to follow me, stalled and went into the deck.
This whole 'stalling to evade' tactic is quite nasty too, although I must admit they recover from it a
lot quicker than I do...
