Gemfan Vortex 12x10E Glass Fiber Nylon Electric Propeller

The Gemfan Vortex 12x10E is a two-blade electric propeller for fixed-wing aircraft, 12 inches across with a 10-inch pitch and moulded in glass-fibre-reinforced nylon. With its pitch close to its diameter, it trades some static thrust for airspeed compared with a 12x6 or 12x8 of the same size.

Key features

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

• Textured leading edge for efficiency at high RPM; slim tips reduce noise and tip vortices

• Anti-slip hub surface holds firmly against the prop adapter

• Factory tested with dynamic balance control for smooth running

• Reducer rings for 3, 3.17, 4, 5, 6 and 8 mm shafts included
