Gemfan Vortex 16x10 Glass Fiber Nylon Electric Propeller (1 pc)

The Gemfan Vortex 16x10 is a two-blade, 16-inch propeller with a 10-inch pitch for large electric fixed-wing aircraft and UAVs, sold as a single prop. A middle-of-the-range pitch gives a balance of take-off pull and cruise speed on big airframes. Choose standard (E, CCW) or reverse (R, CW) rotation from the options.

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.

Pick the E (CCW) prop for a conventional front-mounted tractor motor and the R (CW) prop for a pusher layout. On a twin, fit one of each with the motors spinning in opposite directions so their torque cancels. A 16-inch prop stores a lot of energy: bench-check current draw with a wattmeter and keep clear of the prop arc whenever the battery is connected.
