There are four variations on this exercise:
Clockwise pirouetting easy figure eights
Clockwise pirouetting hard figure eights
Counterclockwise pirouetting easy figure eights
Counterclockwise pirouetting hard figure eights
The "easy" figure eights are figure eights where the heli moves away from you at the ends of the figure eight, and the "hard" figure eights are figure eights where the heli moves towards you at the ends of the figure eight.
