A drone also known as a multicopter is like a helicopter but has several rotor blades to produce lift. There are Octocopters with eight rotors, Hexacopters with six rotors, Quadcopters with four rotors, and Tricopters with three rotors. There are also helicopters with one rotor but we have mostly transitioned away from helicopters since mulitcopters offer a more stable platform. We use mostly Quadcopters for aerial media which have four rotor blades, they have a nice balance of lift to weight ratio and are very efficient to operate. The media likes to call all these drones so ok we can call it that too.
