The Lynxmotion Multirotor Erector Set (M.E.S.) UAV construction system is made up of interchangeable modular components, allowing you to design and create your own custom multirotor UAV / drone; from quadcopters and hexacopters, X8 and more. The system is based around nearly indestructible aluminum brackets which incorporate four 2-56 threaded mounting holes on the side. The plates are made from non-conductive, durable G10 composite and the tubes are ultralight carbon fiber.  Parts can be purchased individually, and there are starter kits based on the modular concept.
