When the occupant boarded the flying object 1 and the flying object 1 ascended from the ground, the displacement flap 4a of the flap portion 4 was positioned at a neutral position along the roll axis R as shown in FIG. 5A. In this state, when the propeller 3Aa of the first propeller portion 3 rotates, an airflow from above to below is generated, and the flying object 1 rises from the ground.

When the surfaced flying object 1 moves, the passenger drives the flying object 1 while sitting and leaning forward so that the front side of the aircraft 2 faces downward. As a result, the flying object 1 moves in the horizontal direction.

After that, when the airframe 1 turns, as shown in FIG. 5B, it is provided on the displacement flap 4a of the flap portion 4 provided on the first propeller portion 3 on the front side and the first propeller portion 3 on the rear side.

The flow direction of the airflow is changed so that the airflow flows to the rear side of the airframe 2 as it goes downward.

On the other hand, when the displacement flap 4Aa is positioned between the neutral position and the front limit position P2, when the airflow from the upper side to the lower side of the airframe 2 collides with the displacement flap 4Aa due to the rotation of the propeller 3Aa, the airflow is generated. The flow direction of the airflow is changed so that the airflow flows to the front side of the airframe 2 when going from the upper side to the lower side.
