Fin stabilizer amphibious aircraft

The invention provides a fin stabilizer amphibious aircraft which comprises an aircraft body (1) and main wings (2) and further comprises connecting shafts (3) and all-moving control surfaces (4), and the four all-moving control surfaces (4) are installed on the front side and the rear side of the bottom of the aircraft body (1) through the connecting shafts (3); and the four all-moving control surfaces (4) are mounted on two sides of the aircraft body (1), two all-moving control surfaces (4) are mounted at the front end of the aircraft body (1), and the other two all-moving control surfaces (4) are mounted at the rear end of the aircraft body (1). The aircraft has the beneficial effects that a fin stabilizer device is combined with a traditional wing, the fin stabilizer device can play a role in stabilizing when the wing works on the water surface, and the sailing speed is effectively increased; and in the cruising stage of the aircraft, the fin stabilizer device can improve lift force, the flight attitude i
