15 Inch 3K Carbon Fiber 1555 Propeller (CCW+CW)– High-Efficiency Heavy-Lift Drone Propellers

Maximize the flight efficiency and payload capacity of your commercial aircraft with the premium 15 Inch 3K Carbon Fiber 1555 Propeller (CCW+CW). Specifically engineered for heavy-lift industrial applications—including agricultural spraying drones, mapping platforms, and long-range surveillance UAVs—this matched propeller pair delivers exceptional rigidity under heavy loads. While plastic or nylon composite blades flex and warp under tension, the structural integrity of the 15 Inch 3K Carbon Fiber 1555 Propeller (CCW+CW) holds its aerodynamic curvature perfectly, transforming raw motor torque into clean, efficient lifting power.

Stability meets extended battery preservation. The high-modulus 3K carbon fiber weave used in the 15 Inch 3K Carbon Fiber 1555 Propeller (CCW+CW) provides an incredible strength-to-weight ratio, allowing the blades to rapidly adapt to subtle throttle corrections from your flight controller. This immediate response improves multi-rotor hovering accuracy in gusty winds and reduces current draw on your ESCs. Furthermore, the mirror-smooth aerodynamic finish of the 15 Inch 3K Carbon Fiber 1555 Propeller (CCW+CW) suppresses prop-wash turbulence, ensuring a rattle-free flight that improves camera stabilization and prolongs the lifespan of your brushless motors.

🛠️ Key Technical Features

• Propeller Dimensions: 15-inch length with a 5.5-inch pitch (1555) optimized for low-RPM, high-thrust stability.
• Material Composition: Forged from premium 3K twill carbon fiber weave ensuring maximum structural stiffness and ultra-light weight.
• Hub Type Configuration: Standard direct-mount dual-hole layout matching professional heavy-lift brushless drone motors.
• Factory Dynamic Balance: Each blade undergoes rigorous factory balancing to eliminate micro-vibrations and protect motor bearings.
• Aerodynamic Profile: Ultra-thin wing profile designed to slice cleanly through the air, drastically boosting battery flight endurance.
• Package Quantities: Includes 1 matching pair of high-tensile propellers (1 Clockwise - CW and 1 Counter-Clockwise - CCW).

Large-diameter props like the 1555 size experience immense centrifugal forces and bending stresses during flight. Nylon or standard plastic propellers suffer from structural flexing under these heavy loads, which severely degrades aerodynamic efficiency, increases current draw, and causes tracking errors that manifest as video jello or flight instability. Premium 3K carbon fiber completely eliminates this flex, ensuring that the propeller maintains its exact shape even during aggressive altitude recovery maneuvers, resulting in safer control dynamics and maximized flight times. 

The 1555 pitch profile is highly optimized for low-KV, high-torque brushless motors, typically ranging from 3508 up to 4114 or 5010 stator dimensions with KV ratings between 300KV and 400KV. This configuration is most commonly run on high-voltage 4S to 6S LiPo battery systems to maintain lower operational currents, preventing your electronic speed controllers from overheating while generating the immense, stable lift required for industrial drone operations.
