Fuselage and fin

The fuselage consists of the tail boom made of spruce sticks and balsa blocks and the front fuselage block made of Ceiba plywood with veneer side covers offering enough space for the ballast and timer (if you decide to install one).

Start with the tail boom: On a flat working surface protected by a clear plastic film, glue together the balsa blocks 35 and 36. Glue the spruce sticks 38 and 37 to the top and bottom of the balsa block 35+36 with their ends flush with the narrower end of the block as well as matching the edges of the block along its entire length. Double-check the tail boom is straight (not bent up/down, left/right) laying it down on your workbench.
Glue the spruce reinforcement 39 into the gap between 35 and 38.
If you are considering installing a timer (either mechanic or electronic) and dethermalizer, now it is time to trim the openings in the fuselage block 40 as needed. Do not forget to cut an appropriate opening in one of the side covers (42) as well.
On a flat working surface, glue together the assembled tail boom and the front part of the fuselage 40.
Glue the ballast 41 into the opening in 40 and glue both two side covers 42 in place.
Glue the plastic horizontal tailplane support 43 to the top of the fuselage and - spaced to match the width of the horizontal tailplane - the front horizontal tailplane seat 44.
Use the tip of a pointy modeller’s knife to cut slots for the brass tin rudder hinges 47 into the fin 45 and rudder 46. Cyano the hinges into the rudder and then into the fin leaving a small (0.5mm) gap between the fin and rudder.
Glue the fin 45 to the fuselage in front of the horizontal tailplane seat 44; align it exactly along the longitudinal axis of the fuselage and square to the horizontal tailplane attached to its seats 44+43 and fastened by a rubber loop.
Glue two wing dowels 49 into the fuselage.
Lay down the plywood wing seat 48 onto the fuselage and put the wing over it securing it by a rubber loop to the fuselage. Looking from the tail and nose, check if the trailing edge of the wing centre section is parallel to the horizontal tailplane. Trim the top of the fuselage under the wing seat if necessary; once satisfied, glue the wing seat in place. Before the glue has cured check the correct alignment of the wing respective to the horizontal tailplane once more.
Drill a 2.5mm hole for the horizontal tailplane pin 50 in the tail end of the fuselage and glue the pin in place.
Glue the skid 51 in place.
