ExpertPower 9455S Propellers for DJI Phantom 4 Series – 2 Pairs (4 Blades), Self-Tightening, Low-Noise Quick-Release Design
The ExpertPower 9455S propeller set includes two pairs (four blades total) designed for the DJI Phantom 4 series. Each blade weighs just 11.7 grams (0.4 oz) and measures 9.4 inches in length with a 5.5-inch thread, providing a balanced combination of lightness and strength. These self-tightening, quick-release propellers are built to reduce noise during takeoff and landing, making them a practical upgrade for Phantom 4, Phantom 4 Pro, and Phantom 4 Advanced drones.
What makes the 9455S design different from standard Phantom 4 propellers?
The 9455S model is an upgraded version with an aerodynamic shape intended to generate less noise while maintaining steady performance. The blades use a composite hub that allows easy installation without tools—just twist on and they tighten themselves during flight. Each propeller is made from a high-tension plastic that helps keep the blades rigid, contributing to stable flight characteristics.
