This will provide enough family DNA to do a very accurate regional DNA test

    While I like the design, I feel that there were additional drawings/labels needed to make the blade construction easier to understand. I have no problem in figuring it out as I have a background in making aircraft propellers and blades, but without diagrams labeling each step, many will fail to grasp how it goes together IMHO
