1855 (18inch) Reinforced 3K Carbon Propeller Efficiency-Optimized For Matched Heavy-duty Multirotor Drone Propulsion Upgrade 4Pairs

The 1855 reinforced 3K carbon propeller series is a specialized hardware solution designed for medium-to-large cruising and heavy-lift multirotor propulsion systems. Utilizing all-carbon board modified from imported materials, this product aims to maximize the Thrust-to-Watt Ratio through efficiency-optimized 18-inch profiles. Each pair undergoes manual to ensure consistent aerodynamic performance and stability under high-torque fields. The torque leverage is physically aligned with standard 12mm hole-pitch motor interfaces, ensuring geometric integrity during extended mission profiles. These propellers help address the Yaw Tumble effect, providing reliable mechanical feedback and enhanced endurance for professional-grade drone applications.Technical SpecificationsModel: 1855 (2-Blade) SeriesDimensions: 18 inch / Pitch: 5.5Material: 3K Carbon Mounting: Center hole 4mm / Side holes 3mm (12mm pitch)Physical Properties: High Rigidity, Manual BalanceApplication: Heavy-duty Multicopter Efficiency-Optimized MaintenanceDeployment: Extended Mission ProfilesPackage List: Reinforced 3K Carbon Propellers 8PCS (4CW + 4CCW)
