Boeing A160T Robocopter and K-MAX by Lockeed

The Boeing A160T Robocopter is a pilotless helicopter that can lift loads up to 1135 kg. The video of the A160 (2007): http://www.youtube.com/watch?v=gndveJE24bg This robocopter model can also reach an unbelievable height of 12 000 feet (3657 meters above sea level) with 567 kg, this is ideal for the American army in countries such as Afghanistan. Lockeed Martin also offers a robot helicopter model that is just as performing if not more: the K-MAX. The latter may dump more than one load at a time in several places and also has the option of hosting a pilot on board. The KMAX can raise slightly heavier loads than the Boeing A160T, 1362 kg, but it can not fly as high. http://www.youtube.com/watch?v=Zj95SHZCkbM
