The prototype for the e-volo electric multicopter achieved its first manned flight at the end of October last year. It represented huge breakthroughs in battery energy density, electric motor power output and controls software programming. Now that e-volo has proof of concept, they are teaming up with Oshkosh to move forward on single and double seat commercial versions of the electric multicopter called the Volocopter. The multicopter format may seem complicated, but it offers many advantages in terms of ease of controls and stability when compared to a traditional helicopter. e-volo is hoping to achieve 6500 ft flight altitude, 60 mph top speed (100 kph), 990 pound (450 kg) payload and one hour of flight time with the new concepts.
