Conventional bottom blade type trefoil flight vehicles have composite structures wherein a plurality of pairs of fixing plates, forward/backward adjustment blades, and left and right rotation adjustment blades are separately mounted and adjusted, and thus have difficulties in scouting and surveillance in an indoor area due to the heavy weights and the large volumes of the flight vehicles. Another conventional flight vehicle has drawbacks in that flight in the left and right directions is difficult, and an adjustment blade and a fixing plate are arranged adjacent to each other to cause mutual influences of wind and non-uniformity in the flow of wind. The present invention provides a flight vehicle characterized in that three pairs of fixing plates with fixed pitch propellers and adjustment blades are installed at an angle of 120 degrees. The present invention allows anti-torque, hovering, forward/backward advancing, left and right rotation, and flight in the left and right direction of flight vehicles, and scouting and surveillance in a narrow space. The flight vehicle of the present invention is simple in structure and control, lightweight, and small in size, thereby improving power efficiency.
