Lumenier 5x3.5 - 2 Blade Propeller (Set of 4 - Purple)

FPV Drone Racing and Freestyle flying require high-quality propellers that ensure optimal thrust, efficiency and top-end speed to allow pilots to consistently perform at their best. Lumenier prop design starts from the ground up, considering flight speed, blade RPM and other factors to optimize each profile. Leveraging a proprietary algorithm, each prop has a unique airfoil and blade design, rather than using the same blade and duplicating them on double, triple or quad-bladed props. This leads to subtle, yet important, performance improvements that can mean the difference between a win or a DNF on race day.Lumenier props are made of tough, glass reinforced polycarbonate material. Includes 4x 5x3.5 2-Blade Propellers, 2x CW and 2x CCW Design. From the ground up. During the design of any Lumenier propeller, key elements are considered such as blade RPM, motor size and KV, and overall flight envelope. These inputs create operating points such as Reynolds Numbers, Mach, Beta Angles, et
