Arguably the P-51 Mustang was the best fighter aircraft of World War II. This model was designed to be used as a training aid to teach elementary school students the parts of an airplane and aero-dynamics. The ailerons, elevators and flaps require CA hinges. The rudder requires 2 X 1/8" hinge joints. The propeller requires 1 M4 X 20mm bolt. Decal sheets for the RCAF 403 City of Calgary squadron are also included. The fully assembled size is 500mm long X 540mm wide X 140mm high.
