1045 Carbon Fiber CW/CCW Propeller Pair - Yellow

1045 Carbon Fiber CW/CCW Propeller Pair - Yellow

This is a 1045 carbon fibre propeller pair in yellow, sold as a CW and CCW set for DIY multicopters and quadcopters. The page says the props are engineered to improve efficiency and aerofoil stability and can be attached and released quickly.

The specification list gives a 10 inch length, 4.5 inch pitch, 9.5 mm shaft diameter and 25 g weight. Recommended motors are the A2212 in 1000KV, 1400KV, 1800KV and 2200KV with a 30A ESC. At the time of the check the page showed it as sold out at Rs 61.

Key features

• Carbon fibre material: 25 g.

• 1045 size: 10 inch length and 4.5 inch pitch.

• 9.5 mm shaft diameter: as listed.

• Quick release and attach: as described.

• A2212 motors and 30A ESC: the listed recommendation.

• Hole set included: with the CW and CCW props.

How a propeller works

A drone propeller converts motor torque into thrust. Each blade is an aerofoil: as the motor spins the prop, the blades push air downward and the reaction force lifts the aircraft. Diameter and pitch set how the prop behaves. A larger diameter moves more air and suits efficient, lower-RPM flight, while a higher pitch moves the aircraft forward faster per revolution but demands more current from the motor.

Multirotors use pairs of props that spin in opposite directions. Clockwise (CW) and counter-clockwise (CCW) props cancel out the torque reaction so the aircraft does not spin, and the flight controller changes individual motor speeds to steer. Always fit each prop on the motor that turns the matching direction, and check your flight controller motor-direction settings before the first flight.

Fit and balance matter. The hub hole or shaft size must match your motor shaft, and the prop should sit flat and tight with the retaining nut fully secured. Check every blade for chips, cracks and bends before each flight, because a damaged prop causes vibration that shows up as jello in the video and extra heat in the motor. Replace props after a hard crash instead of flying on a damaged set.
