Multirotors, multicopters, rotorcraft, or drones as the media likes to label them are any aircraft with two or more motors with fixed or variable props. There are Dual-Rotors, Tricopters, Quadcopters, Hexacopters, Octocopters, and more that make up this category. Multirotors are very popular in the radio control hobby and there are many configurations to choose from, but most share common components like brushless motors, ESCs, flight controllers, propellers, batteries, etc. Multirotors can be simple and small or huge and complex depending on what you want to do. Many people enjoy FPV racing on small 250-sized quads while others want to use larger machines for aerial photography and video.
