20pcs Fpv Drone Props Propeller: Gemfan Hurricane 51477 Tri-Blade 5 Inch Props for 4S 6S FPV Freestyle Racing, 10 CW and 10 CCW

Product Overview

Each package contains 20 separate 5‑inch propellers manufactured by Gemfan, identified by the model number Hurricane 51477. The set includes ten clockwise (CW) and ten counter‑clockwise (CCW) blades, providing balanced pairs for use on quadcopter platforms.

Design Features

• Tri‑blade construction: three individual blades per propeller.
• Standard 5‑inch diameter suitable for many FPV racing drones.
• Designed to fit 4S and 6S battery configurations, common in freestyle and racing setups.
• Clear designation of CW and CCW blades facilitates easy identification during assembly.

Application Context

These propellers are engineered for flight‑in‑picture (FPV) drones that require high agility and precise control. The 4S and 6S compatibility aligns with the power ranges typically employed in competitive racing and freestyle flights. By offering both CW and CCW options, the set supports symmetrical rotor arrangements, which is essential for maintaining stable flight dynamics on multirotor platforms.

Installation Guidance

When installing these blades, ensure that each motor receives the appropriate orientation: CW blades should be matched to motors that spin clockwise, and CCW blades to those that spin counter‑clockwise. This alignment guarantees balanced torque distribution across all four rotors, contributing to consistent lift and control.

Prior to mounting, inspect each blade for visible damage or defects. If a blade exhibits cracks or warping, it should be replaced immediately to avoid potential in‑flight failure. The set’s uniform size allows for straightforward swapping if a blade becomes damaged during operation.

Compatibility Notes

The 5‑inch dimension corresponds to a common prop size used on many consumer and enthusiast FPV drones. The tri‑blade configuration is a popular choice among pilots seeking a compromise between speed and thrust. When selecting these propellers, verify that your drone’s motor shaft diameter matches the prop’s hub specifications. This ensures a secure fit and reliable performance.

Usage Scenarios

In freestyle racing, pilots often require propellers that can provide quick acceleration and responsive maneuvering. The tri‑blade design is known for generating sufficient lift at high RPMs while maintaining manageable weight. For pilots who prefer a more balanced flight envelope, the combination of CW and CCW blades in a single package streamlines the process of building a symmetrical rotor setup.

During high‑speed races or complex aerial stunts, having matching pairs of CW and CCW blades reduces the risk of asymmetric thrust that could lead to yaw drift. By maintaining consistent blade geometry across all four motors, pilots can focus on flight technique rather than compensating for uneven torque.

Maintenance Recommendations

After each flight session, clean the blades to remove debris that may accumulate on the leading edge or blade roots. Use a soft brush or compressed air to eliminate dust, especially if the drone operates in dusty or sandy environments. Regular cleaning helps maintain the integrity of the blade surface and prevents uneven wear.

Inspect the propellers for signs of abrasion or split edges. Any blade that shows irregularities should be replaced with a new piece from the set. Consistent blade condition across all four motors is vital for maintaining predictable flight characteristics.

Packaging Details

The propellers are individually wrapped to protect each blade during transit and storage. The packaging includes a simple label indicating the product name, model number, and quantity. This labeling aids in quick identification when accessing a specific prop for installation or replacement.

Summary

The Gemfan Hurricane 51477 5‑inch tri‑blade propeller set delivers a standardized 20‑piece package that includes an equal number of CW and CCW blades. Designed for 4S and 6S FPV racing drones, the set supports balanced rotor configurations and offers a consistent prop size that aligns with common racing and freestyle platforms. By providing a clear orientation distinction between clockwise and counter‑clockwise blades, pilots can assemble a symmetrical rotor arrangement without additional tooling or measurement. Regular inspection, cleaning, and replacement of individual blades ensure sustained flight performance and safety across multiple racing sessions.
