The Mesa County (Colo.) Sheriff's Office has begun using a remote-controlled unmanned helicopter to assist with search-and-rescue operations and other duties.
The law enforcement agency is using the Draganflyer X6 copter, which weighs about two pounds, to complement search operations. The mostly carbon-fiber vehicle is powered by brushless motors and rotor blades attached to the end of three arms, according to a story in the Grand Junction Free Press.
