  1. Those look to be variable pitch blades. You might give them each about 1/8
    of a turn and see if it makes a difference.

  2. I think the problem you will have is not blade numbers, but rather the
    profile of the blades. They need to have the same profile as an airplane
    wing, you fan blades appear to have a flat surface. Three blades is a good
    number, look at the old Jacobs system that used three with variable pitch
    to control speed. I have an old Wincharger system that used a two blade
    wood propeller, and I have made replacement blades for it so I have played
    with differing profiles.
