ABSTRACT:
A model airplane which is readily constructed as either a low wing aircraft or as a high wing aircraft. The model airplane has a fuselage which is provided with a recess in the upper portion thereof and a recess in the lower portion thereof. The model airplane has a wing member which is positionable within either of the recesses. The model airplane has an insert member which is positionable within either of the recesses. Thus, the wing member and the insert member are interchangeable within the recesses to form either a high wing aircraft or a low wing aircraft. Thus, the model airplane can be readily convertible from a high wing aircraft to a low wing aircraft and vice-versa.
