On the actual aircraft, the horizontal stabilizer is a single-piece structure whose incidence angle can be adjusted. In this model, the stabilizer is first shaped as a single unit and then divided into two halves. A brass rod is inserted through the fuselage, and the two stabilizer halves are mounted on both sides, clamping the fuselage between them.

The fairing at the fuselage attachment point is made from 0.3 mm plastic sheet to resemble the real structure. The photo shows the tail unit temporarily fitted to the fuselage. Since the final installation will be done after painting, it is not glued at this stage.

Attach fixed tabs to the ailerons, rudder, and elevators. The photo shows the installation of the fixed tab on the elevator. The tab is made from 0.1 mm brass sheet (an aluminum beer can can also be used). Carefully file the trailing edge with a design knife to create a small bonding surface, and glue the brass tab there with instant adhesive.

In the photo, the right side shows the part before the tab is attached, and the left side shows it after attachment. After gluing, apply a thin layer of polyester putty and smooth it out. Tabs on the ailerons and rudder are installed in the same way.
