A toy airplane generally has a fuselage, a nose assembly, a tail assembly, a hear train connected with a double rubber band forming a transmission mechanism, a propeller, a pair of wing seats on the fuselage, a plurality of wings and an undercarriage under the fuselage thereof. The improvement of this toy airplane is a structure that is more releasable and movable, particularly a displaceable wing structure that provides great flexibility to the operator to make their own adjustments. An undercarriage provides possible protection to the propeller from damage when landing.
