With a 5" diameter and 3-blade design, this set of four clear AVAN Flow Propellers from EMAX is ideally suited to help racing drones achieve impressive speeds when paired with high-rpm motors. The highly cambered airfoils work to give better lift without sacrificing speed, as the 4.3" pitch provides improved linear control as you throttle up to speed. Made from a polycarbonate blend with thicker blade roots and hub, each propeller is engineered to achieve a low moment of inertia for better responsiveness, as well as long-term stability and durability. While the blades can work with a variety of motors and speeds, they are best suited for use with EMAX 2206, 2207, and 2306 motors around 2400Kv.
