The horizontal tailplane is to be built directly on the plan protected with a clear plastic film in a similar manner as the wing.

Pin down the balsa bottom main spar 25 (4×1.5 mm balsa) and 4x4mm balsa leading edge 28 on the building plan protected by a clear plastic film; glue all the ribs 26 and the centre rib 27 to them.
Glue the trailing edge 29 and the 4×1.5mm balsa top spar 30 to the ribs.
Cut the triangular gussets 32 from 1.5×8mm balsa stick and glue them into the corners.
Cut and sand the overlapping spars, leading and trailing edges 28, 25, 30, 29 flush to the outer ribs. Glue the tip ribs 31 in place and round their outer edges slightly.
Sand the leading edge to the shape of the tip ribs 31 (Det. K).
Use a 2.5mm drill bit to create a groove for the dethermalizer pin 33 in the centre ribs 27; the pin will be glued in place after covering.
