My recent most fun is a climbing move. I fly at full power straight up. Give full right aileron, meaning all it is physically cabable of, then after a turn or two simultaneously slam in full left rudder, and full down elevator. It snaps once or twoce, like the tail is coming off, then settles into a climbing spin that is much faster than a flat. It's like a sustained climbing snap or tumble. The tail gets way out of line with the flight direction, and stays there as long as you keep pouring on the power. The rate of climb is pretty fast too. It's moving out pretty good.
