The V1S version of the ever popular 5x4x3 prop is a fresh airfoil design that was developed between HQ & Chad Nowak. This particular airfoil was designed for a few key points: efficiency, & reducing prop wash. Additionally, the "V1S" props are manufactured with durable materials, so that they can out last several crashes before needing replacement. Offered in two varities; Nylon & Polycarbonate. 

Molded with a stiffer poly carbonate Material, these props will offer improved thrust levels over the Nylon versions due to less deflection at high RPM's. The trade-off is that they will not be quite as durable as the Nylon counterparts.
