Gemfan Vortex 7x13E 2-Blade Electric Propeller – Glass Fiber Nylon

Gemfan Vortex 7x13E is a high-pitch, 7-inch, 2-blade electric propeller designed for compatible fixed-wing RC aircraft, electric model airplanes, and custom electric propulsion systems. Made from glass fiber nylon, this propeller combines durable construction, advanced aerodynamic design, and lightweight engineering to support efficient operation.

Featuring a 7-inch diameter and an aggressive 13-inch pitch, the Gemfan Vortex 7x13E is intended for electric fixed-wing applications requiring carefully matched propulsion components. Its high-pitch configuration makes correct motor selection, electrical loading, and aircraft compatibility especially important.

Available at RC Store Hub India, this propeller is an option for RC airplane enthusiasts, professional aircraft builders, and educational engineering projects.

Key Features of Gemfan Vortex 7x13E

1. Advanced Vortex Aerodynamic Design

The Gemfan Vortex 7x13E features an advanced blade profile developed for electric fixed-wing propulsion.

Gemfan uses computational fluid dynamics (CFD) simulations during development to analyze airflow and improve aerodynamic characteristics.

The optimized blade geometry is intended to support consistent airflow and effective propulsion under suitable operating conditions.

2. High-Pitch 7×13 Configuration

The Gemfan 7x13E Propeller features a 7-inch diameter with a 13-inch pitch.

This is a relatively high-pitch configuration intended for specialized electric aircraft propulsion applications.

Propeller pitch represents the theoretical forward distance a propeller would advance in one revolution without aerodynamic slip.

Actual flight speed and propulsion efficiency depend on the aircraft, motor, battery, operating RPM, and aerodynamic conditions.

The high-pitch design may place substantial loads on a motor. Always verify motor and electronic speed controller compatibility before use.

3. Durable Glass Fiber Nylon Construction

The Gemfan Vortex 7x13E 2-Blade Propeller is manufactured using glass fiber nylon.

This material provides a practical combination of stiffness, toughness, and durability.

The construction is designed to maintain blade geometry under appropriate operating loads while limiting unnecessary component weight.

Gemfan uses precision molding processes to support consistent propeller quality.

4. Lightweight 10.3g Propeller

Each Gemfan Vortex 7x13E propeller weighs approximately 10.3 grams.

Its lightweight construction helps limit rotating mass in compatible propulsion systems.

Component weight is an important consideration when selecting propellers for electric-powered aircraft.

The total packaged product weight specified by Gemfan is approximately 25.28 grams.

5. Precision Dynamic Balancing

The Vortex series benefits from Gemfan’s dynamic balancing quality-control process.

Proper propeller balancing is important for reducing unwanted vibrations during operation.

Excessive vibration can affect motor bearings, airframe structures, and electronic components.

Gemfan’s balancing procedures are intended to support smooth and reliable flight performance.

6. Optimized Blade Tips

The Gemfan Vortex electric propeller series features thin blade tips designed to reduce aerodynamic losses.

The refined blade-tip geometry helps manage vortex formation and is intended to reduce unnecessary operating noise.

This aerodynamic design contributes to the performance characteristics of the Vortex series.

Actual results depend on the complete propulsion system and operating conditions.

7. Enhanced Anti-Slip Hub

The Gemfan Vortex 7x13E incorporates an anti-slip hub design to support secure installation.

The propeller has a center hole diameter of 6.35mm and comes with five adapter sizes:

• 3mm
• 4mm
• 5mm
• 6mm
• 7mm

These adapters support different compatible mounting arrangements.

Always confirm the adapter, shaft, and propeller mounting hardware fit correctly before installation.

8. High-Quality Manufacturing

Gemfan combines aerodynamic design, precision molding, and quality-control procedures throughout the Vortex series.

The manufacturer highlights its patented structural design, specially treated leading edges, and airflow-optimized blade geometry.

These design elements aim to improve operational consistency and durability when used within appropriate operating limits.

Applications of Gemfan Vortex 7x13E

The Gemfan Vortex 7x13E is designed for compatible electric fixed-wing propulsion applications.

Electric RC Airplanes: Suitable for model aircraft with motors and electronic speed controllers capable of safely handling the propeller’s load.

Custom Fixed-Wing Projects: An option for aircraft builders developing specialized electric propulsion systems.

RC Aircraft Performance Testing: Useful for evaluating propeller performance in appropriately controlled engineering experiments.

Educational Projects: Can be used for studying propeller pitch, aerodynamic behavior, and electric aircraft propulsion.

Replacement Electric Propellers: Suitable for aircraft requiring the same propeller dimensions, pitch, rotation direction, and mounting interface.

Why Choose Gemfan Vortex 7x13E?

The Gemfan Vortex 7x13E combines a specialized high-pitch configuration with aerodynamic engineering and durable glass fiber nylon construction.

Its 7-inch diameter, 13-inch pitch, and two-blade design provide a distinctive propulsion option for compatible electric fixed-wing aircraft.

The Vortex series also incorporates precision balancing, optimized blade tips, and an anti-slip hub to support reliable operation.

However, the 13-inch pitch should not be considered universally compatible with standard 7-inch aircraft motors.

Motor KV, battery voltage, operating current, aircraft characteristics, and propeller loading must be evaluated before selecting this model.

Motor Compatibility and Installation Guidelines

Before installing the Gemfan Vortex 7x13E 2-Blade Electric Propeller, confirm the motor manufacturer’s recommended diameter and pitch limits.

Ensure the motor and ESC can safely handle the expected current draw.

Select the correct adapter and securely mount the propeller using suitable hardware.

Verify the intended rotation direction and blade orientation.

Inspect both blades for cracks, chips, deformation, or other damage before every flight.

Always disconnect the flight battery before installation or maintenance.

Perform initial propulsion testing with appropriate safety precautions and follow manufacturer operating limits.
