AbstractA model airplane is provided wherein the fuselage formed with a tail is horizontally divided and provided at said aft end portion with a vertical stabilizing surface and two horizontal stabilizing surfaces. It is desirable that the aft end portion of the fuselage should be held together and a root or roots of the stabilizing surfaces be located with a smooth and streamlined surface being maintained on the underside of the aft end of the fuselage by insertion from the aft end of the fuselage. This is achieved in that a duct which is open at the aft end of the fuselage extends through the fuselage portions and portions of at least one root of a stablizing surface, and in that a pin is fittingly inserted in the duct. This method of connecting eliminates the need for screws, detents and a well in the underside of the aft end region of the fuselage.
