i can see drones, uav"s doing alot of things that piloted vehicles currently do. take for instance traffic copters or airplanes. even police choppers could all be done with an unmanned vehicle without risking the life of a pilot occupant. I have been fascinated with these marvels of technology for nearly 20 years now and i dont understand what the hold up is on there acceptance into the public service realm. I am also intersted to know how they have such an incrediable range or what type of radio equipment that they use. I ahve tinkered with several ideas myself, but could use a little help with some theories. Joe
