There are many reasons you may need to buy parts and accessories for your drone. Parts wear out — propellers, for instance, and motors and batteries. Things break — parts like landing gear, antennas, and gimbals — which you know if you’ve crashed a few times. You may want to add convenience — buy extra batteries and a quick charger, a carrying case or something as simple as a lanyard for a controller. And sometimes you seek to boost the performance of your drone, flight controller or camera, which means upgrading from original equipment.
All DJI branded parts are OEM parts directly from the Manufacturer.
