A160 Hummingbird

The A160 Hummingbird Unmanned Aerial Vehicle looks like a helicopter but is unlike any other on the market today. It can reach higher altitudes, hover for longer periods of time, go greater distances and operate much more quietly than current helicopters.

The A160 is a verticle take-off-and-landing aircraft and has been designed for long-endurance and long-range missions. Its modular payload design can carry up to 1,000 pounds. And it features a unique optimum speed rotor technology that enables the Hummingbird to adjust the RPM (Revolutions Per Minute) of the rotor blades at different altitudes and cruise speeds.
