12. Installing the snake outers in the fuselage shells
Caution: the snake “outers” (outer sleeves) 64, 65 and 68,
and the GRP rod 70, should be glued to the fuselage over the
full length of the tubes, as these parts stiffen the tail boom
considerably, i.e. the snake sleeves act like the spar caps of
a conventional wing spar.
Figs. 17 - 18
Ensure that the control snakes operate smoothly and freely,
and take particular care to avoid glue running inside the slee-
ves
.
13. Left-hand fuselage shell:
Trial-fit the wing joiner moulding 45 and glue it in place.

Deploy the servo extension leads in the duct provided
.
Glue the rudder servo and the canopy latch catches 22 in
place.

Check once again that the cables are deployed neatly, then
glue the plastic spine 55 in the fuselage shell.

Install the left bellcrank bush 48 for the all-moving tailplane,
and glue it in place.

If you are building the electric version, it is necessary to
install one or more trim weights 35 to suit the motor you in-
tend to fit:
If the motor weighs 100 g: no tail ballast required;
If the motor weighs 130 g: one ball;
If the motor weighs 160 g: two balls (Cularis power set).
Caution: this information is only a guide, and the balance
point should still be checked carefully on the finished model.

14. Right-hand fuselage shell:
Lay the right fuselage shell 4 on a flat table, joint surface
down, and glue the reinforcing tube 68 in place over its full
length using thick cyano.
Fig. 24
Glue the elevator snake outer sleeve 64 in place, together
with the inner sleeve 66 and the pre-formed wire pushrod 62.
Fig. 25
Glue the elevator servo and the switch harness in the fusela-
ge. Note: if you are using different makes of servo, you may
have to adjust the servo location to ensure that the output
device is in the correct position.
Position the latch catch 22 carefully, and glue it in place with
cyano. Deploy the servo and switch harness leads in the
cable duct.
Fig. 26
Glue the plastic spine 55 and the motor bulkhead 46 in place.
Note that the motor bulkhead should be fitted even if you are
making the glider version, as it adds considerable strength to
the structure.
Figs. 27 + 28
Install the right bellcrank bush 49 for the all-moving tailplane,
and glue it in place.
Fig. 29
Mount the swivel pushrod connector 25 on the bellcrank 47,
and install the bellcrank using the tailplane joiner rod 34. As-
semble the pre-formed wire pushrod 62, the inner sleeve 66
and the outer sleeve 64 for the all-moving tailplane linkage,
and connect the pushrod to the servo. Slip the wire pushrod
through the swivel pushrod connector, set it to approximate
length, and tighten the grubscrew 28.

15. Joining the fuselage shells
Please take great care over this stage, as the success of the
model largely depends on it.
First offer up the fuselage shells “dry” (no glue); the parts
should fit together snugly, without requiring force. If necessa-
ry, carry out any minor trimming required. Check that you
have not forgotten any of the internal fittings.
Apply thick cyano to all the contact areas of the fuselage
shells. Work briskly, but not hurriedly - you do have time to
assemble the fuselage accurately. Fit the 2.5 mm Ø tailplane
joiner rod 34 through the tailplane bushes to act as an align-
ment guide.
Fig. 31
Carefully offer up the fuselage shells to each other and align
them quickly and accurately. The fuselage joint line must be
absolutely straight: check for curves by sighting along it from
the nose and tail. Leave the joined fuselage for a few minutes,
keeping it straight, and checking repeatedly that there are no
warps. Don’t be tempted to try any “bending / stress tests” yet,
as the cyano-acrylate takes a few minutes to reach final
strength.
Glue the GRP rod 69 in the channel on the underside of the
fuselage. The receiver aerial also fits in the same channel
later, so make sure there is space for it.
Fig. 32
16. Gluing the fin to the fuselage
Fit the swivel pushrod connector 25 in the outer hole in the
glue-fitting rudder horn 24, with the connector barrel on the
underside, and secure it with the washer 26 and the nut 27.
Glue the horn 24 in the rudder. Offer up the fin 15 to the fu-
selage, make any adjustments required, and glue it in place.
Slip the steel rudder pushrod 63 through the swivel pushrod
connector 25, set the servo and rudder to neutral, and tighten
the grubscrew firmly.
Fig. 33
17. Tailplane
The tailplane 13 + 14 takes the form of two all-moving panels.
You have already installed the linkage components inside the
fuselage, and the joiner system consists of parts 50 - 52.
Rotate the joiner pin to and fro about ten times to remove any
rough edges; it should then rotate smoothly.
