These HQ 3-blade props are a standard for pilots around the world. If you prefer a 3 blade prop, you ought to give this prop a try. It's lightweight and great for those who would like to pinch grams but are not willing to go down to a biblade prop. Lots of my team pilots fly these props on their 702 motors.
