Rayi 17.5x6.5 CF Folding PROP

Rayi delivers the 17.5x6.5 carbon fiber folding propeller, a premium ultra light carbon fiber folding propeller built for professional multirotor, VTOL, and long-endurance UAV platforms. As a specialized carbon fiber folding propeller manufacturer, we engineer every blade from aerospace-grade T700 carbon fiber and epoxy resin, achieving an exceptional strength-to-weight ratio that directly reduces drone takeoff weight, extends flight time, and increases payload capacity — critical advantages for agriculture spraying, logistics delivery, inspection, and hybrid VTOL operations.

If your project demands maximum efficiency without sacrificing portability, this 17.5x6.5 carbon fiber folding drone propeller is the upgrade you need. At only 27g per blade, it is significantly lighter than standard plastic or entry-level carbon props, lowering overall system energy consumption while delivering strong static thrust. The swept-back winglets at the blade tips effectively reduce centrifugal pull and vortex drag during cruise flight, while the push-type quick-release folding mechanism collapses the blades neatly for compact storage and easy transportation — perfect for field teams and OEMs shipping complete drone systems.

Performance and Advantages

The 17.5x6.5 carbon fiber folding propeller is designed as a high thrust folding propeller for medium‑large motors:

• Maximum Flight Endurance: The optimized 6.5-inch pitch and high-efficiency airfoil reduce power draw, giving your drone noticeably longer flight times and higher payload capability.

• Ultra-Lightweight Strength: T700 carbon fiber construction with 38% carbon content delivers superior rigidity and fatigue resistance while keeping weight extremely low — ideal for extending battery life on medium-to-large multirotor platforms.

• Low Vibration & Quiet Operation: Precision dynamic balancing minimizes noise and protects motors/bearings, ensuring smoother flights and longer component life.

• Reliable Folding for Logistics: Swept-back winglets and quick-release design allow compact storage and fast deployment, reducing shipping volume and field setup time.

• Durable in Harsh Environments: Low water absorption and wide temperature range make these high efficiency folding propeller for UAV suitable for agriculture, firefighting, surveying, and industrial missions.

Purchasers upgrading to these lightweight folding drone prop for long endurance consistently report improved efficiency and reliability across VTOL transition and heavy-lift applications.

Main Applications

The 17.5x6.5 carbon fiber folding propeller is ideal for:

• Multirotor drones and professional UAV platforms

• VTOL aircraft and hybrid fixed‑wing VTOL drones that require folding propellers for transition and low drag in cruise

• RC aircraft and large multirotor with medium–high power requirements

• Surveying and mapping drones, inspection drones, agriculture UAVs and industrial drones where long endurance and high thrust are needed

The folding design allows the propeller blades to fold back when the motor is off, reducing drag for VTOL fixed‑wing cruise and making transportation and storage easier for large UAV systems.If you are looking for other sizes, materials, or models, please take a look at Rayi’s list of propellers.
