I wanted to make a variant by arr...anging 4 staggered blade elements.
So that the set was not too big I reduced it in size. So I also used smaller magnets (10x1 neodymium).
Once built I realized that the magnets used were low in gauss and I had to bend them. That is, I put one inside and one outside. At the same time, this meant that the blades had greater inertia as they had a greater mass away from the axis of rotation.
