Replacement 8331 Low Noise Folding Propellers for Drone Overview These replacement 8331 folding propellers are designed to reduce noise and improve endurance for compatible drones. They are a non original manufacturer replacement part and feature a softer blade profile compared to the 8330 propeller to help lower acoustic output. Key benefits Noticeable noise reduction: Aerodynamic blade shape lowers overall noise by about 4 dB and reduces acoustic power by approximately 60 percent, helping achieve quieter flights in noisesensitive environments. Improved efficiency and endurance: Blade geometry and folding design improve power conversion and responsiveness, supporting longer and more stable flights. Durable and easy to use: Built for routine replacement with simple installation to reduce maintenance time and get you back in the air quickly. Specifications Model: Replacement 8331 Low Noise Propeller Diameter X Pitch: 8.3 inch X 3.1 inch Compatibility: Fit For Pro PLATINUM Drone Color options: gold or silver Notes: This is not an original manufacturer component.
