The VORTEX 18X12E/R is a glass-fiber nylon electric propeller specially designed for medium- to large-sized electric fixed-wing aircraft and UAV platforms. Made from lightweight glass-fiber-reinforced nylon, each propeller weighs only 78.7 g, effectively reducing rotational inertia while maintaining excellent structural strength and durability.

With an 18-inch diameter and 12-inch pitch, combined with an optimized aerodynamic airfoil design, the propeller delivers stable and efficient thrust output, achieving a well-balanced combination of power performance and flight efficiency. It is ideal for electric fixed-wing aircraft, UAVs, and lightweight aviation model platforms that require long endurance, responsive power delivery, and stable flight performance.

The 31.5 mm hub with a 6.35 mm (0.25-inch) center bore provides reliable installation compatibility and secure connection. The E/R dual-rotation design supports different electric propulsion systems and aircraft configurations.

Product Specifications

Key Features

1. 18 × 12 Specification — Balanced Thrust and Cruise Efficiency

The 18 × 12 configuration combines a large propeller diameter with a 12-inch pitch to provide a good balance between thrust output, power response, and cruising efficiency, making it suitable for a wide range of electric fixed-wing aircraft and UAV applications.

2. Aerodynamically Optimized for Electric Propulsion

The optimized airfoil profile is designed specifically for electric propulsion systems, helping deliver smooth and efficient thrust while maintaining stable performance across different flight conditions.

3. Glass-Fiber Nylon — Strength Meets Lightweight Design

Constructed from glass-fiber-reinforced nylon, the propeller provides an excellent combination of strength, durability, and low weight. At only 78.7 g per propeller, it helps reduce rotational inertia and contributes to efficient power delivery.

4. Matte-Finished Leading Edge — Optimized for High-Speed Operation

The leading edge features a matte surface treatment designed for high-speed operating conditions, helping improve the propeller's overall suitability for demanding electric propulsion applications.

5. Anti-Slip Hub Design

The hub incorporates an anti-slip textured surface to enhance contact and grip between the propeller and mounting components, helping improve installation stability during operation.

6. Strict Dynamic Balancing

Each propeller undergoes strict dynamic balancing control to help minimize vibration during high-speed rotation, contributing to smoother operation and improved propulsion-system stability.

7. E/R Dual-Rotation Design

Available in E/R rotation configurations, the propeller can be matched to different electric power systems, aircraft layouts, and multi-motor configurations.
