An electric multicopter (100) that has a plurality of propellers (1). The multicopter (100) is provided with an electric motor (2), at least one main battery (3), a generator (4), an engine (5), and a battery status detection unit (71). The electric motor (2) drives the propellers (1). The main battery (3) is a first electric power source that supplies electric power to the electric motor (2). The generator (4) is a second electric power source that supplies electric power to the electric motor (2). The engine (5) drives the generator (4). The battery status detection unit (71) detects abnormalities in the main battery (3). When the battery status detection unit (71) has detected an abnormality in the main battery (3), the generator (4) directly supplies the electric motor (2) with electric power that has been converted from motive power from the engine (5). 种直升机，其是多旋翼直升机(100)，具有多个螺旋桨(1)，采用电动式结构。该多旋翼直升机(100)具备电动马达(2)、发电机(4)、发动机(5)、蓄电池状态检测单元(71)、及至少个主蓄电池(3)。电动马达(2)驱动螺旋桨(1)。主蓄电池(3)是向电动马达(2)供电的第1电源。发电机(4)是向电动马达(
