Gemfan Vortex 9x6E Glass Fiber Nylon Fixed-Wing Propeller (Pack of 2)

The Gemfan Vortex 9x6E is a two-blade electric propeller for fixed-wing aircraft from Gemfan's Vortex series, made from glass-fibre-reinforced nylon. This pack contains two identical standard-rotation 9x6E props, giving a single-motor plane a fitted prop and a spare.

Key features

• CFD-optimised airfoil: blade profile developed for electric propulsion.

• Textured leading edge: aimed at efficiency at high RPM.

• Slim blade tips: reduce noise and tip vortices.

• Anti-slip hub: secure grip on the prop adapter.

• Factory-tested dynamic balance: smooth running with less vibration passed into the airframe.

A large diameter with low pitch puts the emphasis on thrust for bigger, slower aircraft such as trainers and powered gliders. Both props turn the same way, so this pack does not supply a counter-rotating pair for a twin. Check full-throttle current with a wattmeter against your motor's rating before flying.
