4. Gluing the latch catches and the motor bulkhead in
the fuselage
Glue the latch catches 22 in both fuselage shells (right and
left).
Glue the motor bulkhead 50 in the recess in the right-hand
fuselage nose 4 using Zacki ELAPOR®.
Fig. 5
5. Preparing the cable holders
Use cyano to glue the socket of the 400 mm extension leads
# 8 5029 to the cable holders 34, keeping the ends flush.
Route the leads through the strain relief lugs as shown.
Fig. 6
6. Installing the cable holders
Glue the cable holders 34 in the appropriate recesses in
both fuselage shells. Use Zacki ELAPOR® (without activator),
and push them in swiftly as far as they will go.

7. Installing the wheel frame
Glue the wheel frame 52 in one of the two fuselage shells
using Zacki ELAPOR®. Ensure that no adhesive gets inside
the through-hole for the screw.

8. Installing the fuselage stiffening tube and cables
Wipe activator over the hexagonal fuselage stiffening tube
66, then apply thick cyano to the surfaces of the appropriate
channel in the fuselage shell. Swiftly push the tube into the
channel, taking care to keep the fuselage perfectly straight.
Allow the adhesive to set hard, then slip the 600 mm extension
leads # 8 5032 through the tube. Temporarily tape the leads
to both ends to prevent them slipping out again.

9. Installing the rudder and elevator servos
First set the servos to neutral (centre) from the transmitter.
Check that the clevis 33 and the pre-formed rudder pushrod
31 are a snug fit in the holes in the servo output arms; you
may need to open up the holes slightly.
Connect the clevis to the innermost hole in the elevator servo
output arm. The pre-formed rudder pushrod is later connected
to the centre hole of the rudder servo output arm.
Centre the servo from the transmitter (or use a servo tester),
and push the output arms onto the servo shafts, keeping
them at right-angles to the case sides.
Connect the servo leads to the extension leads projecting
from the fuselage stiffening tube 66, and tape the plugs and
sockets together for security before drawing them forward
through the tube. On the inside of the right-hand fin moulding
you will find a circular void in which about 3 cm of the servo
leads can be stowed.
If you ever need to replace the servos or repair them (new
gears), the extra cable allows easier access to the servos,
and there will be a little spare cable available for any soldered
joints required. Push the remainder of the two servo leads
into the appropriate channels in the right-hand fuselage shell
before they "disappear" into the fuselage stiffening tube.
The servos themselves should be installed as shown in the
illustration. It is sufficient to secure each servo by applying a
little hot-melt adhesive to the outside of the mounting lugs.
This method makes it easy to remove the servos for subse-
16
quent repair without damaging the fin.

10. Joining the fuselage shells
Please take particular care over this stage, as it is important
to the overall success of the model.
Carefully sand the joint surfaces using 320-grit abrasive paper,
then place the fuselage shells together "dry" - without glue.
Check that the halves fit together snugly, without requiring
force. Make any minor adjustments required to obtain a good
fit.
Apply thick Zacki Elapor to the joint surface of one fuselage
shell, then swiftly fit the two shells together, taking care to
align everything accurately.
Hold the fuselage together for a few minutes, pressing the
shells inwards lightly, and checking constantly that the
component is completely straight. Don't try bending it or
placing it under strain, as the cyano-acrylate needs a little
while to achieve full strength.

11. Installing the tailplane screw support
Press the two M5 nuts 36 into the cylindrical screw guides
in the tailplane screw support 59, then glue the support 59 in
the recess in the right-hand fuselage shell 4 using Zacki
Elapor.
Fig. 12
12. Completing the elevator linkage
Screw the clevis 33 onto the end of the elevator pushrod 32
and adjust it so that the distance between the two linkage
points is about 136 mm. Slip the pre-formed end of the rod
through the hole in the tailplane screw support 59, and engage
the clevis in the innermost hole in the elevator servo output
arm.
Fig. 13
13. Completing the fin
Glue the left fin moulding 9 to the right fin shell, which is an
integral part of the fuselage. Take great care to avoid adhesive
getting into the elevator pushrod guide.
Fig. 14
14. Installing the fin stiffeners
The channels in both sides of the fin are intended to accept
the 1.3 mm Ø stiffener rods 68, which are 215 mm long. This
is accomplished by running a little Zacki Elapor into the
recesses, then pressing the stiffeners into place. Complete
the job by running thin cyano along the length of both stiffeners;
apply a little activator to speed up the curing process.
Fig. 15
15. Installing the tailwheel
Glue the dummy tailwheel 57 to the raised area at the tail
end of the fuselage.
Fig. 16
16. Cutting the rudder free
Use a sharp modelling knife to complete the cut at the bottom
of the rudder. Align the blade with the existing surface to
obtain a neat cut line.
Move the rudder to and fro repeatedly until the hinge is free-
moving.
