as with the wings, the construction methods used in the fuselage and empennage of the tn-1 are similar to those in the tainan mita 3 two-seater. the primary fuselage structure is formed from steel tubes, with wood stringers to shape the fabric covering. the nose-cone is shaped from glass reinforced plastic. the fin and tailplane, the latter mounted on top of the fuselage, are wooden framed with plywood skins but the control surfaces are fabric covered; the rudder extends down to the keel. all the tail surfaces are straight tapered; there is a trim tab on the starboard elevator. the tn-1 lands on a fixed, unsprung but braked monowheel undercarriage, assisted by a tailskid.
