Drone, DJI P4P Part 137 9455S Low-Noise Quick-Release Propellers (Pro/Pro+V2.0)

The 9455S propellers have a brand new aerodynamic design giving the Phantom 4 series an impressive noise control performance. When used with the Phantom 4 Pro V2.0, up to 4dB (60%) of aircraft noise is lowered during takeoff and landing. Noise reduction is also enhanced when used with the Phantom 4 Pro, but not as much.
