I agree with Bruce sort of. why a 3 blade? 2 blades are easier to get, so are spinners.
I am not buying the arugument that 2 blade props are more efficient
3-blades are fine on full scale but lose something when downsized. In our sizes the 2-blade wins. Get up over 36 inch dia and I'd have to look at it again.
