Gemfan Vortex 10x6 Glass Fiber Nylon Electric Propeller (2 pcs)

The Gemfan Vortex 10x6 is a two-blade, 10-inch propeller with a 6-inch pitch for electric fixed-wing aircraft, supplied as a pair. One inch more pitch than a 10x5 trades a little static thrust for extra cruise speed, making it a sensible all-round choice for sport planes and trainers built around a 10-inch prop. Both props in the pack are the standard-rotation E version, listed as CCW.

Key features

• Tough construction: glass-fibre-reinforced nylon resists bending and impact while keeping the blade profile true under load.
• CFD-optimised blades: slim tips reduce tip vortices and noise, and a frosted leading edge helps limit airflow separation at high RPM.
• Secure mounting: the textured hub face grips the prop adapter so the prop does not creep under the nut.
• Dynamically balanced: balanced at the factory to keep motor vibration low.
• Fits common shafts: 6.35 mm (1/4 in) bore, with six adapter rings for 3, 3.17, 4, 5, 6 and 8 mm.

The E version suits a conventional front-mounted (tractor) motor; a pusher layout or the opposite motor of a counter-rotating twin needs the reverse-rotation R version. After any prop change, check current draw with a wattmeter on the bench so the motor and ESC stay within their ratings.
