USM Evo Alloy Extended Arms for F450 & F550
Extend your multicopter’s capabilities with our EVO aluminium arms!
We are proud to unveil the first in our fantastic new line of multirotor products: USM Evo aluminium multirotor arms.
With our wealth of multirotor experience has come a degree of frustration with the design of many commonly used arms. We felt that we could do better, and USM Evo arms were born.
We have lovingly crafted these arms for maximum stiffness, minimal weight and ease of use. Our arm design was optimized using finite element analysis to remove as much excess material as possible. What remains is a strong, incredibly rigid arm that makes stock plastic multirotor arms look and feel like children’s toys!
Made from durable aircraft grade 6061 T6 tempered aluminium alloy, these beautiful, slender yet incredibly stiff arms offer a game-changing upgrade over the ubiquitous plastic multirotor arms. The arm has a remarkably thin profile, reducing aerodynamic drag.
USM Evo arms are 50mm longer than the plastic arms. This extra length allows you to install up to 13” propellers on your F 450 quadcopter, or 12” propellers on your F 550 multicopter. Larger props are more efficient, giving you longer flight times and better stability. USM Evo arms can be used as X8 or Y6 configuration.
