Master Airscrew 3MR Series Three-Blade Propellers
Master Airscrew's U.S.-manufactured 3MR Series three-blade propellers are optimized for efficient hover and forward flight on multirotor, VTOL and long-range FPV platforms. Their glass-fiber-reinforced composite construction provides strength and durability, and each propeller is factory balanced.
The 7 x 3.7 variant is intended for compact propulsion systems, while the larger 10 x 5 version supports aircraft requiring increased propeller diameter and thrust.
