The 7728 Quick Release Folding Propellers for Mavic Pro Quadcopter from DJI are designed to be used in combination with the Mavic Propeller Cage. The propellers feature a folding design that reduces the drone's footprint when not in use. Quick release attachment enables them to be installed or removed easily, without special tools.
Note: These propellers should only be used together with the Propeller Cage. Please do not use these propellers without the propeller cage, or else the flight time and maximum thrust will be reduced.
