Multirotor drones with various configurations have been developed and, from now on, drones with new configurations will be proposed and developed. A drone configuration for minimizing disturbance moments due to a wind gust at hover has been investigated. Induced velocity by the simple momentum theory was used in the analysis, and the aerodynamic interference among the rotors and their wake was ignored. This analysis is just a fundamental one. An analysis about the aerodynamic interference among rotors and their wake will be an important research subject for solving the present problem more perfectly.
