9x4.5EA VORTEX CCW Propeller Pair With CFD-Optimised Blades For Fixed-Wing Electric UAVs
The 9x4.5EA VORTEX electric propeller is designed for compact fixed-wing electric aircraft requiring responsive thrust, smooth rotation, and efficient forward flight. Its 9-inch diameter and 4.5-inch pitch provide a practical balance of acceleration, control, and energy efficiency when matched with a compatible motor, ESC, and battery system. The reverse-rotation CCW configuration is suitable for counter-rotating and multi-motor aircraft arrangements.
Manufactured from glass-fiber-reinforced nylon, each propeller provides high toughness, bending resistance, and reliable dimensional stability. The CFD-optimised blade profile supports efficient airflow and thrust generation, while the frosted leading edge helps reduce airflow separation at high RPM. Slim blade tips, smooth contours, an anti-slip hub surface, and precision dynamic balancing help minimise vibration, aerodynamic drag, operating noise, and unnecessary power loss. The pack includes 2 CCW propellers.
