Gemfan Vortex 7x13R Specifications

Key Features of Gemfan Vortex 7x13R

1. Reverse-Rotation Propeller Design

The Gemfan Vortex 7x13R is the reverse-rotation variant of the Vortex 7×13 electric propeller.

It is intended for aircraft propulsion systems requiring the reverse version rather than the standard 7x13E model.

Correct propeller rotation and blade orientation are essential for producing thrust in the intended direction.

Before installation, verify motor rotation, propeller orientation, and the aircraft manufacturer’s propulsion requirements.

2. Advanced Aerodynamic Blade Design

The Gemfan Vortex 7x13R features an optimized aerodynamic blade profile developed for electric fixed-wing aircraft.

Gemfan uses computational fluid dynamics (CFD) simulation during Vortex series development to analyze airflow behavior and propulsion characteristics.

The refined blade geometry aims to improve aerodynamic efficiency while providing reliable structural performance.

Actual operating efficiency depends on the motor, battery, aircraft design, and flight conditions.

3. High-Pitch 7×13 Propeller Configuration

The Gemfan 7x13R Propeller features a 7-inch diameter combined with a 13-inch pitch.

This relatively high-pitch configuration is intended for specialized electric aircraft applications where forward-speed performance is an important consideration.

Propeller pitch refers to the theoretical distance a propeller advances during one revolution without aerodynamic slip.

Because of its high pitch, the 7x13R can impose substantial loads on an electric motor.

Always verify the motor manufacturer’s recommendations and ensure the powertrain can safely operate with the selected propeller.

4. Durable Glass Fiber Nylon Construction

The Gemfan Vortex 7x13R 2-Blade Reverse Propeller is manufactured from glass-fiber-reinforced nylon.

This material provides a combination of toughness, rigidity, and lightweight construction.

Glass-fiber reinforcement helps maintain the intended blade geometry under appropriate operating conditions.

The durable material and precision molding process support consistent manufacturing quality.

5. Lightweight 10.3g Design

Each Gemfan Vortex 7x13R propeller weighs approximately 10.3 grams.

Its lightweight design helps limit rotating mass in compatible electric propulsion systems.

The manufacturer lists a packaged product weight of approximately 25.28 grams.

Actual flight endurance and propulsion efficiency depend on the complete aircraft configuration rather than propeller weight alone.

6. Precision Dynamic Balancing

The Gemfan Vortex electric propeller series incorporates strict balancing quality-control procedures.

Proper propeller balance is important for reducing unwanted vibration during operation.

Excessive vibration may affect motor bearings, aircraft structures, and electronic components.

Gemfan’s balancing process is intended to support smoother operation and consistent product quality.

7. Optimized Blade Tips and Leading Edges

The Gemfan Vortex series features refined blade tips and specially treated leading edges.

According to the manufacturer, these design elements help reduce aerodynamic losses, manage airflow, and improve operating efficiency.

The optimized blade-tip geometry is also intended to reduce unwanted noise and vortex formation.

Actual noise and aerodynamic performance vary with operating RPM and aircraft configuration.

8. Anti-Slip Hub and Mounting Adapters

The Gemfan Vortex 7x13R incorporates an anti-slip hub surface designed for secure installation.

The propeller features a 6.35mm center hole and comes with five mounting adapter sizes:

• 3mm
• 4mm
• 5mm
• 6mm
• 7mm

These adapters provide mounting options for compatible propeller shaft arrangements.

Always ensure the selected adapter and mounting hardware provide a secure fit.

Applications of Gemfan Vortex 7x13R

The Gemfan Vortex 7x13R is intended for compatible electric fixed-wing aircraft applications.

Electric RC Airplanes: Suitable for aircraft designed to use reverse-rotation electric propellers with the correct motor and ESC combination.

Counter-Rotating Propulsion Systems: Can be considered for aircraft using opposite propeller rotation directions, provided the installation and thrust requirements are correctly matched.

Custom Fixed-Wing Aircraft: An option for builders developing specialized electric propulsion configurations.

RC Aircraft Replacement Parts: Suitable where the original propeller’s diameter, pitch, mounting interface, and rotation direction match.

Educational Engineering Projects: Useful for studying propeller geometry, electric propulsion, rotational direction, and aerodynamic performance.

Why Choose Gemfan Vortex 7x13R?

The Gemfan Vortex 7x13R combines a specialized reverse-rotation design with high-pitch blade geometry and durable glass fiber nylon construction.

Its 7-inch diameter and 13-inch pitch make it a distinctive option for compatible electric fixed-wing propulsion systems.

The Vortex series incorporates aerodynamic optimization, precision balancing, lightweight construction, and an anti-slip hub.

These features are intended to support consistent operation when the propeller is correctly matched with the aircraft powertrain.

However, the 13-inch pitch is not suitable for every 7-inch electric aircraft motor.

Motor KV rating, operating voltage, current capacity, and aircraft requirements must be considered before installation.

Motor Compatibility and Installation Guidelines

Before installing the Gemfan Vortex 7x13R Reverse Electric Propeller, confirm the motor manufacturer’s recommended propeller diameter and pitch.

Verify that the motor rotates in the required direction and that the blades are correctly oriented.

Ensure the aircraft frame or fuselage provides sufficient propeller clearance.

Select the appropriate mounting adapter and securely install the propeller using suitable hardware.

Inspect both blades for cracks, chips, bending, or other visible damage before each flight.

Always disconnect the aircraft battery before installation, adjustment, or maintenance.

Avoid operating the propeller outside the motor, ESC, or manufacturer’s recommended limits.
