Abstract
A multicopter having a plurality of propellers is configured to be electrically operated. The multicopter is provided with electric motors, at least one main battery, a generator, an engine, and a battery condition detecting section. 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. The battery condition detecting section detects abnormality of the main battery. When the battery condition detecting section detects the abnormality of the main battery, the generator supplies the electric power that has been converted from motive power from the engine directly to the electric motors.
