Black Knight Transformer Multicopter By Advanced Tactics

Examples
• Cierva Air Horse - a British three-rotor "heavy lift" helicopter first flying in 1948. Three rotors were used to give a large lift without compromising rotor strength.
• e-volo - a German prototype electric multicopter with 16 rotors, the first electric multicopter in the world to achieve manned flight. The large number of low-cost motors make it economical, quiet and provide redundancy with ability to maintain control with up to four failed motors.
• Advanced Tactics’s Black Knight Transformer, is a multipurpose drone that can be used to evacuate wounded troops. The Black Knight Transformer may look like a Go-Go-Gadget boxcar on wheels, but the autonomous machine is only in the first stages of development. U.S. military hopes to use the Transformer to fill the need of a “Multi-Mission Medical and Casualty Evacuation Unmanned Air Vehicle/Unmanned Ground Vehicle.”
