Hi All,
After see many thread about 1/72 model, i just want to design my own 1/72 too. I tackle with Boeing A-160 Humming Bird. An unmanned helicopter. below is some description from wikipedia
The Boeing A160 Hummingbird (military designation: YMQ-18A) is an unmanned aerial vehicle (UAV) helicopter. Its design incorporates many new technologies never before used in helicopters, allowing for greater endurance and altitude than any helicopter currently in operation.
The development of Hummingbird was begun by Frontier Aircraft. In May 2004, the company was acquired by Boeing and integrated into Boeing Phantom Works and then into the Advanced Systems group of Boeing Integrated Defense Systems.
The A160 continues with developmental flight tests in 2010, but test flights have already demonstrated greater endurance, higher altitudes, more extensive autonomy, and greater payload. The program has ambitious goals of a 2,500-mile (4,000 km) range, 24-hour endurance, and 30,000 ft (9,100 m) altitude. Flights are largely autonomous, with the aircraft making its own decisions about how to fly itself so as to meet certain objectives, rather than relying on real-time human control. Maximum speeds are over 140 knots. The aircraft is 35 ft (11 m) from nose to tail and has a rotor diameter of 36 ft (11 m). Early A160s were powered by modified Subaru automotive engines, but newer versions use Pratt & Whitney PW207D turboshaft engines
