This picatinny rail system was designed for the DJI Phantom 4 drone. There is a rail mount for the left side (designated with the large L) and the right side (desigated with the large R) of the Phantom 4. In addition, there are four mounts: 1 that wil hold a tactical flashlight, like a Surefire, completely enclosed facing horizontal to the Phantom, the next will hold if facing vertical (downward) on the Phantom, the next is a universal mount that can use zip ties or rubber bands to secure a flashlight facing horizontal, and the last is the universal mount that will hold a flashlight vertical. The picatinny mounts can be secured to the Phantom using 2 M3 nuts and 2 M3x30MM bolts on each side (a total of 4 x M3 nuts and 4 x M3x30MM bolts). In addition, the fully enclosed tactical flashlight holder can use any M4 bolt/nut to secure the flashlight to the mount. The rail system is designed to be modular to allow additional mounts to be designed and attached to the Phantom 4, allow it be easily be outfitted for any search and rescue mission. The included flashlight mounts allow the Phantom 4 to be equipped with tactical flashlights capable of high luminousity to provide much needed light for dawn, dusk, and night time search and rescue operations, allow the drones to be used outside of daylight hours.
