Gemfan Vortex 15x10E Glass Fiber Nylon Electric Propeller

The Gemfan Vortex 15x10E is a two-blade electric propeller for larger fixed-wing aircraft, 15 inches across with a 10-inch pitch and moulded in glass-fibre-reinforced nylon.

Key features

• Vortex blade with a CFD-optimised airfoil developed for electric propulsion

• Textured leading edge for efficiency at high RPM

• Slim blade tips and a streamlined profile reduce noise and tip vortices

• Anti-slip hub surface for mounting stability on the prop adapter

• Factory tested with dynamic balance control for smooth running

The 6.35 mm (1/4 in) bore fits a matching prop adapter directly; on a smaller motor shaft, use a reducer ring or an adapter sized to the shaft. A 15-inch prop sweeps a 190 mm radius, so check ground clearance, and pair it with a motor rated for 15-inch props on your cell count. Confirm current draw with a watt meter on the bench before the first flight.
