Functional rc supercharger

Complete WORKING supercharger. I modeled 100% of everything! only things that need to be bought are 4 ball bearings with: O.D 12.7mm (-1/2") I.D 4.8mm (-3/16").
if it is assembled correctly, it should push air. I have made 2 complete blowers and they both push air!

MY OWN PERSONAL DESIGN, ANY RE-DESIGNS ARE RE-MAKES AND ARE COPIES OF MY DESIGNS!
