Aerial vehicles are a trending topic amid engineers and scientists. With the advent of drones and multicopters, they strenuously began to study the control of such aircrafts, not only in normal flight mode, but also in the case of troubles. For example, if quadcopter has two symmetric faulty motors it is called a as bispinner [5]. Bispinner is an example of a new type of aircraft, the main feature of which is the continuous rotation around the vertical axis. The prefix in the name of the aircraft indicates the number of propellers in the aircraft. The appearance of aircraft of this type has put forward new requirements of safety when debugging control algorithms at the initial stage, because between the takeoff and the crush landing of such an aircraft with no proper control takes very little time. The use of simulators and plants can significantly reduce the risks of falling aircraft. Therefore, to study a tree-degree-of-freedom (3DOF) bispinner with shifted center of mass may be a promising start, as it is relatively simpler than 6DOF heavy quadcopter with two symmetric faulty motors.
