The utility model discloses a simulated aircraft and a system thereof. The simulated aircraft comprises a bracket which is horizontally provided with a first rotating shaft. One end of the first rotating shaft extends out of the bracket and is fixedly connected to a transmission box. One side of the transmission box is connected to a cockpit. The first rotating shaft is provided with a hollow cavity which is internally provided with a second rotating shaft. The second rotating shaft and the first rotating shaft are coaxially arranged. One end of the second rotating shaft extends into the transmission box and is interlinked to a fourth transmission shaft through a linkage mechanism. The horizontal projection of the fourth rotating shaft is perpendicular to the horizontal projection of the first rotating shaft. The cockpit is hinged to the end part of one end of the fourth rotating shaft which extends out of the transmission box through a pin shaft. According to the simulated aircraft and the system, the second rotating shaft is creatively arranged in the first rotating shaft, thus the whole simulated aircraft has the advantages of simple structure, small occupied space, complete functions, low manufacturing cost and easy installation.
