• 3-blade star shape: aerodynamic design.

• ABS / polycarbonate composite: high-strength material.

• Smooth, low-vibration flight: as described.

• Crash-resistant build: for long life.

• Quieter operation: without losing performance.

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.
