Gemfan 12x8E / 12x8R Vortex: High-Velocity Glass Fiber Nylon Propeller

The Gemfan 12x8 Vortex series is a high-pitch, high-performance propeller engineered for electric RC aircraft that demand speed and aggressive pulling power. Available in both Standard (E) and Reverse (R) rotations, these propellers are the perfect choice for high-speed sport planes, twin-engine builds, and performance-oriented multirotors.

Molded from Glass Fiber Reinforced Nylon, the 1208 Vortex offers the structural rigidity needed to maintain its 8-inch pitch under high RPM, ensuring maximum aerodynamic efficiency and rapid airspeed.

Key Features

• Precision Rotation Options: Available in both CW (Standard) and CCW (Reverse) configurations to provide perfectly counter-balanced torque for twin-motor or multirotor setups.

• Reinforced Composite Build: The glass fiber-infused nylon construction provides the stiffness of carbon fiber with the durability of polymer, resisting "blade flutter" at high speeds.

• High-Velocity "E" Profile: Optimized specifically for electric outrunners, the 12x8 geometry focuses on high-speed cruise efficiency and superior dynamic thrust.

• Vibration-Free Performance: Each propeller is precision-molded and factory-balanced to eliminate high-frequency resonance, protecting your motor bearings and flight electronics.

• Reduced Motor Strain: The lightweight 30.4g design allows for faster throttle response and improved energy efficiency, helping to extend your battery life.

• Universal Mounting: Comes with a full set of shaft adapters (3mm to 8mm), making it a drop-in fit for a wide variety of brushless motor brands.

Ideal Applications

• High-speed Sport and Aerobatic RC planes.

• Twin-engine "Warbirds" and Scale aircraft.

• Performance-oriented Quadcopters and Multirotors.

• Electric Sailplanes requiring high-climb authority.

Package Includes

• 1x 12x8 Vortex Propeller (Select E for Standard or R for Reverse)

• 1x Full Set of Shaft Diameter Adapters (3mm, 3.17mm, 4mm, 5mm, 6mm, 8mm)
