Gemfan 1447 14x4.7 Carbon Nylon Propellers (1CW+1CCW)

A matched pair of 14 x 4.7 inch two-blade propellers in carbon-filled nylon, one clockwise and one counter-clockwise. The large diameter and low pitch suit big slow-fly multirotors running low-KV brushless motors, where efficient hover and long flight times matter more than speed.

Key features

• Carbon-filled nylon blades: stiffer than plain nylon or ABS while staying light
• Low 4.7-inch pitch for steady, efficient lift on hover-focused frames
• Blade tips angled at 15 degrees to reduce tip vortices
• Plastic reducer rings included for 3, 4, 5 and 6 mm motor shafts

Specifications

• Size: 14 x 4.7 in
• Blades: 2
• Material: Carbon nylon
• Weight: 57 g
• Colour: Black
• Reducers: 3, 4, 5 and 6 mm
• Pack: 1 CW + 1 CCW

One pack covers two motors, so a quadcopter needs two packs and a hexacopter three. Seat the reducer that fits the shaft without play, and balance each prop before the first flight: at 14 inches, even a small imbalance shows up quickly as vibration.
