Stay safe with this set of white Propeller Guards for DJI Phantom 4 from Ultimaxx. Propellers are what make your Phantom 4 fly, but they are also what make it dangerous in the event of an accident. Help reduce the risk to innocent bystanders, as well as the risk to propeller and property damage, with these prop guards. You get a full set of four propellers, each designed to snap on and off your rotors quickly. Please note that once installed, these guards are designed to work with the Phantom 4's obstacle-sensing system to not cause any interference.
