Lumenier 4x4x3 V2 - Propeller (Set of 4 - Transparent Blue)

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.

This is the new Version 2 of the popular Lumenier 4x4x3 propeller. This new version has greatly improved the durability of the propeller by using a crash resistant polycarbonate material. This allows the propellers to resist breaking in a crash or prop strike. Now you can clip a gate or a tree branch and keep flying! The new V2 series also feature semi-transparant colors for a cool look.

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 V2 props are made of ultra durable polycarbonate material.

Includes

• 4x V2 4x4 3-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, etc. which are used to guide the design process.

Performance based on Science.

Given the operating points and design goals Lumenier produces unique airfoils leveraging a proprietary genetic algorithm that iterates 10s of thousands of possible airfoils and compares them to each other and also a library of well known existing airfoils. This creates the best possible and most suitable combination of airfoils as well as overall blade design. For this reason, no 2 blades on any Lumenier propeller are the same.

Airfoil design with a purpose.

Calculus and proprietary algorithms help translate 2D coefficients of lift, drag, and moment into 3D coefficients that account for high blade loading and near static thrust conditions that a multi-copter will encounter during flight.
