As he described, cross-controlling (crossing up the controls) is using the opposite inputs of coordinated flight, coordinated turn, etc to achieve a maneuver. In the game, the high torque planes actually do it well, just not on the same angle of attack that he described...the K4, LA7, Spit14 do it very well out of a coordinated turn in either direction, preferring the torque side. Try it in a 5 degree right hand climb. You'll like it. I'm fairly certain you'll die in real life trying this, lol unless you're in a high performance aircraft.
That being said, the supreme commander of this particular counter controlling move is the KI84. Much more smooth than the others.
