Removing the flash from the fuselage (1) using a sharp balsa knife.
Glue the carbon fibre tube (2) in the fuselage, taking care to keep the underside of
the fuselage perfectly straight (resting on the building board).
Glue the bushes (3) in the fuselage, taking care to avoid excess glue running inside
them.
Glue the dowel support (4) in the fuselage nose; take care to press it down to the
bottom of the recess, otherwise the canopy will not fit properly. Glue the dowel (5) in
the canopy (6).
Glue the retaining clip (7) in the recess in the wing (21), with the open end facing up.
Glue the lug (8) in the canopy (6), pressing it firmly into place.
The next step is to cut through the linking pieces at the ends of the rudder and
elevator (attached to the fin (11) and tailplane (12)), to allow them to deflect freely.
Caution: on no account cut off the control surfaces, as the thin line of SOLIDPOR left
at the pivot axis acts as the control surface hinge.
Note: the fin (11) and tailplane (12) each consist of a fixed portion - which is later
glued permanently to the fuselage (1) - and a moving control surface. Each of the
control surfaces is actuated by a servo and "snake" linkage. Directions (such as right
or left) always refer to the model as seen from the tail, looking forward.
Glue the fin (11) to the tailplane (12), keeping it exactly vertical. Cut the snake outer
sleeves (9) and (10) to the exact lengths stated in the Parts List. In the picture they
are shown ready to install.
The snake outers project by 195 mm at the front; mark this point, then glue the
sleeves in the fuselage using UHU-por. Note: UHU-por is a type of glue known as a
contact adhesive. For this reason you should apply the glue along the channel in the
fuselage, press the snake sleeve into it, then remove it again immediately. Allow the
glue to air-dry (this takes about five minutes), then press the sleeve into the channel
again.
Unscrew the servo output levers and cut off the unwanted arms using side-cutters.
Locate the hole in the output levers for the swivel pushrod connectors (13) and drill
them out to 2.1 mm Ø. Tip: if you don't have the correct size of drill bit, enlarge the
hole using the tip of a pointed balsa knife, working from both sides; the balsa knife
works quite well as a make-shift tapered reamer.
Fit the swivel pushrod connectors (13) in the holes and secure them with the self-
locking nuts (14). Caution: don't over-tighten the nuts; the pushrod connectors should
be just free enough to swivel smoothly.
