The DJI Phantom 3 Professional/Advanced Landing Gear features a pair of replacement landing skids and the hardware required for installation. Landing skids are designed to protect the FPV camera and the quadcopter's shell during landing and also to provide a stable platform when the aircraft is not in use. They are for the Phantom 3 Professional/Advanced; other Phantom models, such as the Phantom 3 Standard, are not supported. 

Note: A compass is included with the landing gear. If the old compass needs to be replaced, you will need to open up your Phantom 3 during the installation process. If the old compass does not need to be replaced, please place the old compass inside the new landing gear during the installation process.

Essential for protecting the FPV camera during takeoff and landing
Keep on hand as a backup or use to replace the original set in the event of a hard landing
