these blades are great would recommend to othersI bought these props for my tricopter build. They are nice and quiet with plenty of grip. I did encounter one prop that needed the center cleaned up, there was a bur that caused the prop not to seat correctly. Also the props are pretty good but still need to be balanced. Check your props!
