4 Pairs 9450 Self Tightening Drone Propeller(4CW+4CCW) Compatible with DJI Phantom 2/3/3PRO, Low Noise Propellers, Replacement Parts for Drone Blades

Product Overview

Eight individual propeller blades, assembled into four pairs, are offered in this set. The blades come in two orientations: four clockwise (CW) and four counterclockwise (CCW). The designation 9450 refers to the part number that identifies the series and the design of these blades.

Self‑Tightening Mechanism

Each blade in the set incorporates a self‑tightening feature. The design allows the blade to maintain its position once it is seated on the motor shaft, reducing the need for manual adjustment. This feature is included in all eight blades, regardless of orientation.

Low‑Noise Design

The blades are engineered to operate with lower levels of audible vibration. This attribute is highlighted as a characteristic of the set. The design does not claim specific decibel reductions but indicates a general reduction in noise relative to typical propellers.

Replacement Blades for DJI Phantom Series

The set is listed as compatible with the DJI Phantom 2, DJI Phantom 3, and DJI Phantom 3 PRO drones. This compatibility means that the blades are designed to fit the motor mounts and specifications used on those models.

Application and Use

When a drone blade is damaged or worn, replacement blades are required to restore flight performance and safety. This set provides a complete set of blades that can be swapped for those that are no longer functional. The number of blades—four clockwise and four counterclockwise—matches the standard configuration on the listed DJI Phantom models.

Installation Notes

Installing a blade involves aligning the blade’s mounting pattern with the motor shaft and securing it in place. Once the blade is seated, the self‑tightening feature engages to hold the blade firmly. The orientation (CW or CCW) is important for maintaining the correct flight balance on a quadcopter platform.

Material and Construction

While the exact composite or polymer composition is not specified, the blades are constructed to meet the dimensional and load specifications required by the DJI Phantom 2, 3, and 3 PRO. Each blade is engineered to maintain structural integrity during typical flight conditions.

Maintenance and Longevity

Propeller blades experience wear from repeated launches, landings, and exposure to environmental factors. Replacing damaged blades with this set ensures that the drone continues to operate with blades that meet the original design specifications. The self‑tightening feature reduces the likelihood of blade loosening during operation.

Use Case Scenarios

Drone pilots who perform aerial photography, surveying, or recreational flight often encounter blade damage from hard landings or collision with obstacles. Having a ready supply of replacement blades for the DJI Phantom 2, 3, and 3 PRO streamlines the repair process and reduces downtime.
