8x4E/8x4R Drone Propeller VORTEX Electric Glass Fiber Nylon Grey CW/CCW 2Pc

Gemfan 8x4E / 8x4R Glass Fiber Nylon Propeller Set (CW+CCW)

Product Description

The Gemfan 8x4 Vortex Electric Propeller Set is a heavy-duty, high-performance solution for RC airplanes, drones, and electric-powered aircraft. This matched set includes both standard (E) and reverse (R) rotation propellers, making it the industry standard for twin-engine builds or multi-rotor platforms that require counter-rotating blades to eliminate torque roll. Molded from premium glass fiber reinforced nylon, these propellers offer exceptional structural rigidity, allowing them to maintain their aerodynamic profile even under high-thrust loads. Each prop is precision-balanced to ensure ultra-smooth operation, protecting your motor bearings and providing a stable flight platform.

Key Features

• Counter-Rotating Pair: Includes one 8x4E (Standard) and one 8x4R (Reverse) propeller for perfectly balanced thrust in multi-motor configurations.

• Industrial-Grade Material: Constructed from high-strength glass fiber reinforced nylon for superior stiffness and impact resistance compared to standard plastic.

• Precision Aerodynamics: The 8x4 blade profile is optimized for high static thrust and efficient low-to-mid speed cruising.

• Vibration-Free Performance: Strictly dynamic-balance tested to minimize vibration, ensuring a quieter flight and increased motor longevity.

• Comprehensive Adapter Set: Includes a 6-hole adapter kit (3mm, 3.17mm, 4mm, 5mm, 6mm, and 8mm) to fit almost any motor shaft on the market.

• Robust Hub Design: Features a 9.3mm center thickness and a 19mm disk diameter for a secure, high-torque connection to the motor.
