The Lumenier 5x5x3 Butter Cutter propeller is designed for high speed and extreme performance. This unique airfoil provides incredible thrust throughout the entire power-band, and especially the top end. In addition to incredible power potential, the Butter Cutter also has great efficiency. Most high performance propellers suffer from high amp draw to achieve top-end thrust, but the Butter Cutter's advanced airfoil allows for both high performance and good efficiency. These props give you a "locked in" feel while flying and really grip the air while cornering.
The Butter Cutter propellers are made from an ultra-durable, 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! Each blade is 100% balanced direct from the mold as well, giving you a "butter smooth" flight.
These Butter Cutters come in a custom "WILDWILLY" Pink color named after Lumenier pilot Nick Willard.
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.

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.

Great Prop With One Drawback review by Noah on 6/19/2017
These props are bad@$$. My 210 mini quad SCREAMS when running these bad boys. I'm not a racer. I do mostly freestyle stuff and these are the only props I use. I would say that they don't fly as smoothly as the Lumenier 5x4x3 props and they also produce, at least on my quad, some pretty gnarly noise in my FC. However, I managed to solve this problem by soft mounting my FC with some rubber noise dampening screws. BUT the one issue that I have with these props is that they bend easily. When I crash with these props, they usually end up bending right near the hub of the prop. (I think Wild Willy has a video on this issue.) The blades can be bent back close to their original position, but this creates an imbalanced prop which is not optimal. (I must confess, I do it anyway.) It is better to replace the entire prop than to try to bend it back into position. All in all, if you are willing to stock up on a good supply of these props and you are able to somehow tune out the noise in your FC, these props are killer. They are fast and pack a punch.
butter smooth :) review by pablo on 3/11/2017
very nice props and very smooth no matter the color, but for me blue or pink, I don't like q black look, in this prop.
