Package contains 2pcs CW and 2pcs CCW propellers for multirotor aircraft Key benefits Correct rotation pairs: Two clockwise (CW) and two counterclockwise (CCW) propellers ensure proper thrust balance and stable rotation when replacing worn or damaged blades. Quick field replacement: Packaged as a complete set to swap out all blades on a quadcopter that uses matched CW and CCW props, reducing downtime. Consistent performance: Designed to restore symmetrical lift and reduce vibration when installed in matching motor positions. Features and important attributes Contents: 2pcs CW and 2pcs CCW, four propellers total. Function: Replacement propellers that restore correct rotational direction and flight balance for compatible multirotor platforms. Compatibility: Intended for quadcopters or other multirotor aircraft that require two CW and two CCW propellers. Verify fit with your model before installation. Size note: Package description indicates the rotation arrangement. Confirm physical dimensions on the original equipment or product listing to ensure proper mounting. Construction: Manufactured for routine use and service replacement. Handles typical operational loads when installed correctly. Practical use scenarios Field after a prop strike: Carry this set as emergency spares to damaged blades on site and continue flying. Regular maintenance kit: Swap out fatigued propellers during scheduled maintenance to maintain smoother flight and lower vibration. Spare parts for travel: Pack the set when traveling with your multirotor to avoid performance loss from missing or broken blades. Installation tips Match CW props to the CWmarked motors and CCW props to the CCWmarked motors. Check mounting holes, shaft diameter, and screw pattern before tightening. Balance each propeller and inspect for cracks or chips before use. What this set solves Eliminates imbalanced thrust caused by mismatched or damaged blades. Provides a complete rotation pair set for common quad configurations, simplifying replacement and reducing the risk of installation errors. Notes Verify compatibility with your aircraft model and the required propeller dimensions prior to . This listing describes the rotation arrangement and quantity only: 2pcs CW and 2pcs CCW.
