Gemfan Vortex 10x7 Glass Fiber Nylon Electric Propeller (2CW+2CCW)

The Gemfan Vortex 10x7 is a two-blade electric propeller from Gemfan's Vortex fixed-wing range: 10 inches across, 7 inches of pitch, moulded in glass-fibre-reinforced nylon. The set holds four props, two 10x7E (CW) and two 10x7R (CCW), covering a twin-motor plane with counter-rotating props plus a spare pair, or several replacements for a single-motor model.

Key features

• CFD-optimised Vortex airfoil with slim blade tips that cut tip-vortex loss and noise

• Textured hub face grips the prop adapter for a secure fit under load

• Factory tested and dynamically balanced to keep vibration down

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

Mount it on a collet or bolt-on prop adapter with the ring that matches your motor shaft. A 10x7 loads a motor harder than a 10x5 or 10x6 of the same diameter, so check your motor maker's prop chart and confirm current draw with a watt meter before the first flight.
