Gemfan 8045 8x4.5 Carbon Nylon Propellers with Reducers (1CW+1CCW)

A matched pair of 8 x 4.5 inch two-blade propellers in carbon-filled nylon, one clockwise and one counter-clockwise, for small slow-fly multirotors and DIY quads on low-KV brushless motors. The included reducer set lets the same props fit a wide range of motor shafts.

Key features

• Carbon-filled nylon: stiffer than plain nylon or ABS props of the same size
• Low 4.5-inch pitch for stable, efficient hover
• Reducer rings for 3, 3.17, 4, 5, 6 and 8 mm shafts
• Blade tips angled at 15 degrees to reduce tip vortices

Specifications

• Size: 8 x 4.5 in
• Blades: 2
• Material: Carbon nylon
• Weight: 24 g
• Colour: Black
• Reducers: 3, 3.17, 4, 5, 6 and 8 mm
• Pack: 1 CW + 1 CCW

One pack covers two motors, so a quadcopter needs two packs. Use the reducer that sits on the shaft without play, and balance the props before the first flight to keep vibration away from the flight controller.
