Dear Capt. Slog,
  It really does apply sir. The rotational mass is in front of the pivot, and only supported at one end. A perfect scaled up example of the bicycle wheel experiment.
  If you were to eliminate the effect of air pressure against your turbine (windmill
in a vaccum chamber) and spin the blades with a motor, you unit would pivot away from
the direction the blades were spinning at the top of their arc.   Gus

It is supported at one end, BUT not in the same manner as the bicycle wheel, the end of which rests on a fulcrum, and that is a major difference.  

If you were to clamp the bike wheel axle in the same manner as a wind turbine axle and repeat the exp, there wouldn't be the precession that you see in the original.  The precession only occurs when the wheel tries to drop under gravity.
