1045 Carbon Fiber Propeller Pair, 10x4.5 Inch (1 CW + 1 CCW)

A matched pair of 10 × 4.5 inch two-blade carbon fibre propellers — one clockwise, one counter-clockwise — in the 1045 size that F450 and F550-class quadcopters and hexacopters fly on. They are rated for brushless motors from 800 to 2200KV, which covers the 2212-size motors those frames are usually built around.

Key features

• CW + CCW pair: one prop of each rotation, so a single pair covers two adjacent motors.
• Wide motor range: on 800–1400KV motors they give smooth, longer flights for FPV and aerial photography; on higher-KV motors they deliver faster, more acrobatic flying.
• Epoxy-coated blades: carbon fibre blades finished with an epoxy resin cover.
• Reducer rings included: adapters in eight bore sizes fit the props to common motor shafts and prop adapters.

• In the pack: 1 CW + 1 CCW propeller

A quadcopter needs two pairs and a hexacopter three. Fit each prop to a motor spinning in its direction, and balance the props before the first flight to keep vibration away from the flight controller.
