Gemfan Vortex 7x9E 2-Blade Electric Propeller – Glass Fiber Nylon

Gemfan Vortex 7x9E is a premium 7-inch, 2-blade electric propeller designed for fixed-wing RC aircraft, electric-powered model airplanes, and custom aerial platforms. Manufactured using glass-fiber-reinforced nylon, this propeller combines a lightweight structure, durable construction, and aerodynamic blade design for efficient electric propulsion.

With a 7-inch diameter and 9-inch pitch, the Gemfan Vortex 7x9E is suitable for compatible electric aircraft propulsion systems that require a high-pitch propeller. Its carefully engineered blade profile is intended to support stable airflow, consistent performance, and responsive power delivery.

Available at RC Store Hub India, this Gemfan electric propeller is suitable for RC aircraft enthusiasts, model airplane builders, educational institutions, and custom fixed-wing projects.

Key Features of Gemfan Vortex 7x9E

1. Advanced Aerodynamic Blade Design

The Gemfan Vortex 7x9E features an aerodynamic airfoil profile developed to improve propulsion efficiency.

Gemfan uses computational fluid dynamics (CFD) simulation during its Vortex propeller development process to evaluate airflow and blade characteristics.

The resulting blade geometry is designed to provide consistent airflow and efficient thrust generation when matched with a suitable motor and aircraft configuration.

2. Durable Glass-Fiber Nylon Material

The Gemfan Vortex 7x9E 2-Blade Propeller is manufactured using glass-fiber-reinforced nylon.

This material combines the toughness of nylon with the stiffness provided by fiber reinforcement.

It helps the propeller maintain its intended geometry under normal operating loads while offering a practical balance between strength and component weight.

The high-precision molded construction is designed to support consistent manufacturing quality.

3. High-Pitch 7×9 Configuration

The Gemfan 7x9E Propeller features a 7-inch diameter and a 9-inch pitch.

Its relatively high pitch makes it suitable for electric aircraft applications where forward-speed characteristics are an important consideration.

A propeller’s pitch represents its theoretical forward travel through a solid medium in one complete revolution. Actual movement through air is affected by aerodynamic slip and operating conditions.

Because high-pitch propellers can place substantial loads on electric motors, selecting the correct motor, battery, and electronic speed controller is essential.

4. Lightweight 9.8g Design

Each Gemfan Vortex 7x9E propeller weighs approximately 9.8 grams.

Its lightweight structure makes it suitable for electric aircraft projects where component weight and rotating mass influence propulsion performance.

The manufacturer lists a packaged product weight of approximately 24.1 grams.

Actual aircraft efficiency and flight endurance depend on motor performance, battery capacity, aircraft weight, and operating conditions.

5. Precision Dynamic Balancing

The Vortex series is manufactured with strict dynamic balance quality control.

Proper balancing is important because an unbalanced propeller can produce unnecessary vibration during operation.

Excessive vibration may affect motor bearings, airframe components, and onboard electronics.

Gemfan’s manufacturing process is designed to provide consistent propeller quality and stable operating characteristics.

6. Optimized Blade Tips

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

The optimized tip geometry is intended to minimize vortex formation, improve airflow characteristics, and reduce unwanted noise.

The streamlined blade profile supports efficient operation across compatible electric propulsion systems.

7. Anti-Slip Hub Design

The Gemfan Vortex 7x9E features an anti-slip hub surface designed to improve mounting security.

Its center hole measures 6.35mm, and the product includes adapters in five sizes:

• 3mm
• 4mm
• 5mm
• 6mm
• 7mm

These adapters provide additional mounting options for compatible propeller shaft arrangements.

Always confirm correct mounting compatibility and follow the motor manufacturer’s installation instructions.

Why Choose Gemfan Vortex 7x9E?

The Gemfan Vortex 7x9E combines an optimized blade profile with durable material construction and precision manufacturing.

Its glass-fiber-reinforced nylon blades are designed to provide stiffness and toughness without unnecessary weight.

The Vortex series also features an anti-slip hub, aerodynamic blade tips, and factory balancing processes to support consistent operation.

For RC airplane builders requiring a 7-inch electric propeller with a 9-inch pitch, this model offers a performance-oriented option.

However, propeller selection must always consider the complete powertrain.

Motor KV rating, battery voltage, available current, and aircraft operating requirements influence whether a particular propeller is suitable.

Installation and Safety Guidelines

Before installing the Gemfan Vortex 7x9E 2-Blade Electric Propeller, verify the motor manufacturer’s recommended propeller specifications.

Check that the aircraft has sufficient clearance for the full 7-inch propeller diameter.

Select the correct adapter and ensure the propeller is properly aligned and securely mounted.

Disconnect the flight battery before installation or maintenance.

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

Never operate a visibly damaged propeller.

When testing the propulsion system, use a suitable open area and keep hands, clothing, and other objects away from rotating blades.

Follow all applicable motor, ESC, battery, and airframe operating limitations.
