Gemfan 9045 9x4.5 Glass Fiber Nylon Propellers (1CW+1CCW)

A matched pair of 9 x 4.5 inch two-blade propellers in grey glass-fibre-reinforced nylon, one clockwise and one counter-clockwise, for slow-fly multirotors and DIY quads running low-KV brushless motors. The low pitch for a 9-inch prop favours efficient hover and longer flight times over speed.

Key features

• Glass-fibre-reinforced nylon: rigid enough for steady thrust, tough enough for training knocks
• Prop reducer set included to fit common motor shafts
• Blade tips angled at 15 degrees to reduce tip vortices
• Low-cost replacement option for trainers and test rigs where props are changed often

Specifications

• Size: 9 x 4.5 in
• Blades: 2
• Material: Glass-fibre nylon
• Weight: 30 g
• Colour: Grey
• Pack: 1 CW + 1 CCW, with reducer set

One pack covers two motors, so a quadcopter needs two. Check that the supplied reducers match your motor's shaft or prop adapter, and balance each prop before flying.
