The show airplane 4 has an elevating rudder, a rudder and an aileron, and the elevating rudder, the rudder and the aileron can swing under the driving action of corresponding motors. The arrangement mode and the driving mode of the elevator, the rudder and the ailerons are the same as those of the existing static display model airplane, and are not repeated. Lamp strips corresponding to the profiles of the elevator, the steering rudder and the ailerons of the display airplane 4 are respectively arranged on the elevator, the steering rudder and the ailerons so as to enhance the display effect through the flicker of the specific lamp strips in the display process.

The three-axis pan-tilt comprises a pitch drive motor 3, a roll drive motor 5 and a direction drive motor 6. The stator of the direction driving motor 6 is fixed on the upright post 2, the rotor of the direction driving motor 6 is distributed along the vertical direction and is fixed with the stator of the pitch driving motor 3, the rotor of the pitch driving motor 3 is distributed along the horizontal direction and is fixed with the stator of the roll driving motor 5, the rotor of the roll driving motor 5 is distributed along the horizontal direction and is perpendicular to the rotor of the pitch driving motor 3, and the rotor of the roll driving motor 5 is fixed with the display airplane 4.
