This is a cover and canopy for the S500 quadcopter. It has all the accessory mounts for the 3DR pixhawk and APM modules (LED, USB, and safety switch. Also included is the LED lamp mount and a gimbal mount that attaches perfectly to the HK mobius gimbal. I printed everything with PLA with a 25% infill and I put 3 shells on the canopy. The LED headlamp boards can be found on amazon for about $6 for the Vktech Super Bright 5V 24 Piranha LEDs Lamp http://www.amazon.com/gp/product/B00JKB8H5K?psc=1&redirect=true&ref_=oh_aui_search_detailpage.
