The planes shouldn't matter, but velocity on the blades should vary between 0 and 21-ish (ie min & max of domain). If you go to "scale" what are the min & max values for x & y?  Just want to confirm the axis origin is also correct. 

The shaft should be a moving wall (wall bc) with rotation the same as the blade volume. The blade velocity will be zero rotation relative to the cell zone.
