To reduce the capacity of a driving part, and miniaturize a radio control aeroplane.
This aeroplane has a flight unit 11, and a ground controller 12 connected with the flight unit 11 via a communication part and flying the flight unit 11. The flight unit 11 comprises a shell part 14, a driving part arranged to the shell part 14, a propulsion device for generating a propulsion force by driving the driving part, a main wing 25 comprising a plurality of wing units 38, 39 relatively movably arranged, an opening/closing mechanism 43 for changing a substantial area of the main wing 25 by changing the relative positions of the respective wing units 38, 39, and a drop device 64 for selectively holding and dropping a delivered article. Because a flight speed can be changed by changing the substantial area of the main wing 25, the capacity of the driving part for rotating the propulsion device can be reduced.
