Fig. 27
- Glue the horn in place using robbe Speed (cyano-acryla-
te).
Caution: remember to fit rings of heat-shrink sleeve
over the clevises to prevent them opening acciden-
tally.
Fig. 28
- The illustration shows the fin and rudder components.
Fig. 29
- Glue the horn in the recess using 5-minute epoxy.
Fig. 30
- Glue the fin to the tailplane using white glue.
It is essential to join these parts at right-angles, and
keep the fin exactly central (in line with the fuselage
centreline - see drawing).
Fig. 31
- Connect the prepared elevator pushrod to the horn. Use
the spigots to mark the position of the horn on the elevator.
Fig. 32
- Open up the holes in the control surface to accommodate
the horn spigots. Cut down the horn spigots to a length of
about 4 mm.
Fig. 33
- Hold the horn in position, and mark the outline of the horn
base. Carefully slit the film along the outline using a sharp
balsa knife, and remove the unwanted film.
Glue the horn in place using robbe Speed (cyano-acryla-
te).
Fig. 34
- Use a sharp balsa knife to cut a chamfer in the tail end
of the fuselage about 4 mm wide; this allows more down-
elevator movement in flight.
Fig. 35
- The tail assembly can now be placed on the fuselage again
after threading the pushrods into their sleeves.

Fig. 36
- Glue the tail assembly to the fuselage using white glue.
Fig. 37
- Take great care to position the tail assembly correctly
relative to the fuselage and wings when gluing the parts
together. It is best to check repeatedly that everything is
‚square'. Attach the wing centre section to the fuselage to
check alignment.
Fig. 38
- Screw a threaded coupler into each clevis for the rudder
and elevator linkages. Set the control surface and corre-
sponding servo output arm to neutral (centre), mark the
length of the pushrod - taking into account the length of the
threaded coupler and clevis - and cut it to length. Finally
unscrew the clevis, and solder the pushrod in the threaded
coupler.
Fig. 39
- The illustration shows the completed linkage. Fit rings of
heat-shrink sleeve (supplied) over the clevises to prevent
them opening accidentally.
Fig. 40
- The picture shows the power system components (not
included in the kit) and the sequence of assembling the
propeller.
Fig. 41
- The sketch shows the installation of the power system and
RC components in schematic form.
Fig. 42
- Fix the motor to the motor bulkhead using two M3 screws.
Connect the motor to the speed controller. The picture on
the right shows the motor, propeller and spinner installed
in the model.
Fig. 43
- Install the speed controller under the battery support using
double-sided foam tape.
Fig. 44
- The LiPo battery can now be fixed to the battery support
plate using hook-and-loop tape.
Fig. 45
- The picture shows the battery installed in the fuselage. The
canopy is retained by a peg at the front and magnets at the
rear.
Fig. 46
- Work on the fuselage is concluded by gluing the landing
skid to the underside of the fuselage using 5-minute epoxy.
Fig. 47
- Glue the tailskid in the slot in the tail end of the fuselage,
again using 5-minute epoxy.
Fig. 48
- Temporarily tape the wingtip to the tip rib. Drill 1.5 mm
pilot-holes for the retaining screws, then fix the wingtip in
place with the retaining screws supplied. Repeat the pro-
cedure with the opposite wingtip.
Fig. 49 – Centre of Gravity
Fix the battery in the fuselage in the appropriate position (Fig.
44). Do not connect the battery at this stage.
Attach the wings to the fuselage.
The Centre of Gravity should be at a point 80 mm aft of the
wing root leading edge +/- 5 mm.
