The short kit includes fuselage sides, bulkheads, fin and rudder, elevators, and 1/16″ ply wing root and tip templates for cutting your foam wing cores.  Balsa parts for the horizontal stabilizer are not included.  You get 1/64″ ply stabilizer skins.  When you build the plane, attach the balsa to the stabilizer skin, trim around the edges, and then attach the other skin.
