Abstract:
To provide a helicopter which can be reduced in weight and from which a residual quantity of fluid in a fluid tank can be estimated.SOLUTION: A multi-copter 1 includes: a fuel tank 32 for storing fuel; a propeller 21; and a motor 22 for outputting drive force for the propeller 21. The motor 22 is installed for each of the multiple propellers 21.
