The invention discloses a simulation aircraft and a system thereof. The simulation aircraft comprises a support, a first rotation shaft is horizontally arranged on the support, a transmission case is fixedly connected at one end of the first rotation shaft extending out of the support, and one side of the transmission case is connected with a cockpit. The first rotation shaft is provided with a hollow cavity, a second rotation shat is arranged in the cavity, the second rotation shaft and the first rotation shaft are coaxially arranged, one end of the second rotation shaft extending into the transmission case is in linkage with a fourth rotation shaft through a linkage mechanism, the fourth rotation shaft is perpendicular to the first rotation shat in horizontal projection, and the cockpit is hinged to an end portion of the fourth rotation shaft extending out of the transmission case through a hinge pin. The second rotation shaft is creatively arranged in the first rotation shaft, so the whole simulation aircraft is simple in structure, small in space occupation, complete in functions, low in manufacturing cost and convenient to mount.
