The utility model provides a small-size unmanned helicopter with an up-mounted tail rotor. The small-size unmanned helicopter comprises a helicopter main body, a main rotor, a landing gear, a tail rotor supporting frame and the tail rotor, wherein the upper end of the helicopter main body is connected with the main rotor; the lower end of the helicopter main body is connected with the landing gear; the rear end of the helicopter main body is connected with the tail rotor through the tail rotor supporting frame; the front end of the tail rotor supporting frame is connected with the helicopter main body; the rear end of the tail rotor supporting frame is connected with the tail rotor; and the tail rotor supporting frame is upwards bent at a part, which is 1/4 of the full length of the rear end, and a bending angle is 45 degrees. According to the small-size unmanned helicopter with the up-mounted tail rotor, the height of a tail rotor rotating surface is increased, so that the landing safety is improved, and the flying stability is also improved; and the tail rotor is independently driven by a tail motor, so that the flying stability is further improved.
