单词 quadcopter
释义
quadcopter

Electronics and Electrical Engineering
  • A helicopter with four rotors, all mounted on the same plane. Two rotors rotate clockwise and two anticlockwise. This allows the use of fixed-blade rotors that are much simpler mechanically, while still providing a high level of stability and control. Recent developments in microelectronics and electric motor miniaturization have led to small radio-controlled quadcopters being made available for recreational use from prices as low as £15.
