Thirteen .50 caliber machine guns positioned around this heavy bomber model plane kit demonstrate why the B-17G was referred to as the Flying Fortress. Under the plane, modelers are given the option of assembling the landing gear up or down and the bomb bay doors opened or closed. If left open, admirers of the B-17 model kit will be able to see the full bomb bay with racks and four bombs ready to drop on enemy forces. Intake ducts, elevator, and rudder are all separate from the rest of the wing and fuselage moldings, which gives the plane a more realistic appearance when completed.
