Gemfan Vortex 6x12 Glass Fiber Nylon Electric Propeller (2 pcs)

The Gemfan Vortex 6x12 is a high-pitch two-blade electric propeller for fast fixed-wing models and speed-focused electric UAVs. It comes in packs of two in the rotation you select.

Key features

• 12 in pitch, twice the 6 in diameter: a theoretical 12 in of travel per revolution, tuned for top speed rather than static thrust
• Glass-fibre reinforced nylon resists blade flex under high load
• Strict dynamic balancing keeps vibration low at high RPM
• 6.35 mm bore with four adapter rings (3, 4, 5 and 6 mm) for common motor shafts and prop adapters
• Available as CCW (6x12E, standard rotation) or CW (6x12R, reverse rotation)

Choosing rotation: CCW (E) is the standard prop for a conventional nose-mounted tractor motor; CW (R) suits a pusher mount or the second motor of a twin, where opposite rotation cancels torque. A high-pitch prop loads a motor harder than a low-pitch prop of the same diameter, so check current draw with a wattmeter before flying.
