A multicopter having a plurality of propellers is provided with electric motors, at least one main battery, a generator, and an engine. The electric motors drive the propellers. The main battery is a first electric power source that supplies the electric power to the electric motors. The generator is a second electric power source that supplies the electric power to the electric motors. The engine drives the generator. When a remaining capacity of the main battery is less than a threshold, the generator charges the main battery with the electric power that has been converted from motive power from the engine.
