Assembling the model:
1. Before you start
Check the contents of your kit.
You will find Figs. 1 + 2 and the Parts List helpful here.
Completing the fuselage and tail panels
2. Preparing the control "snakes"
The snake outer sleeves 3/2 are supplied 700 mm long. The first
step is to cut them to the following lengths:
Elevator 43
Rudder 44
Aerial 47
The inner tubes 2/1 are supplied 730 mm long. Shorten the rudder
inner to 705 mm.
Elevator 45
Rudder 46
3. Installing the snake outers in the fuselage shells
Note: we strongly recommend that you glue the snake outer
sleeves 43 and 44, and the aerial sleeve 47, to the fuselage over
their full length, as the sleeves increase the stiffness of the tail
boom substantially.
Ensure that the control systems move freely and smoothly, and
that no glue gets inside the snake outer sleeves.
Left-hand fuselage shell:
Fit the elevator snake 41, 45, 43 (steel rod length: 770 mm) in the
left-hand fuselage shell, with the pre-formed end of the steel rod
at the nose.
Fig. 3
Position the snake outer 43 flush with the front part of the fuselage,
as shown in Fig. 4. Lay the shell down flat, and glue the outer
sleeve 43 in the channel over its full length using cyano.
Fig. 5
Right-hand fuselage shell:
Fit the rudder snake 42, 46, 44 (steel rod length: 720 mm) in the
right-hand fuselage shell, with the pre-formed end of the steel rod
at the nose.
Fig. 6
Position the snake outer 44 flush with the front part of the fuselage,
as shown in Fig. 7. Lay the shell down flat, and glue the outer
sleeve 44 in the channel over its full length using cyano.

4. Installing the wing retainer screw plates
Glue the wing screw plates 33 + 34 together using a little glue,
and install these parts in the moulded recesses in the fuselage
shell 4, again using glue sparingly.
Fig. 9
5. Installing the canopy latch system
The Canopy-Lock latches 22 must be fitted in such a way that the
latch tongues 23 can be engaged between the latches 22 and the
fuselage sides. Spray activator in the latch recesses in the fuselage,
and allow it to air-dry. Apply thick cyano to the joint surfaces of the
latches, and place them immediately in the correct position. Apply
more glue afterwards if necessary.

6. Installing the servos in the fuselage
Set the servos to neutral (centre) from the transmitter and fit the
output levers on them with the arms at 90° to the long case sides.
Trial-fit the servos in the sides of the fuselage as shown in the
illustrations; you may need to make minor adjustments to suit the
servos you are using. Route the servo leads along the appropriate
3 / 2 Ø x 700 mm
3 / 2 Ø x 670 mm
2 / 1 Ø x 600 mm
2 / 1 Ø x 730 mm
2 / 1 Ø x 705 mm
channels towards the rear. Fix the leads in place with a drop of
hot-melt glue, or use 5-minute epoxy. Fix the servos in place in the
same way, using a drop of hot-melt glue on the mounting lugs.
Figs. 11 + 12
7. Joining the fuselage shells
The best adhesive for this stage is medium or thick cyano.
Offer up the left and right fuselage shells 3 / 4 to each other, so that
you can check that they mate together fully: carry out any minor
trimming required to obtain a close fit.
Once you are sure that everything fits properly, apply activator to
the joint surfaces of one fuselage shell, and allow it to air-dry for
about two minutes. Spread out the activator evenly with a rag if
necessary.
Glue the aerial sleeve 47 in the right-hand fuselage shell, taking
care to avoid bending the fuselage.
Apply cyano to the joint surfaces of the second fuselage shell.
Working quickly and carefully, bring the fuselage halves together
and align them immediately. Note that the fuselage joint line must
be straight; there should be no trace of a curve.

8. Attaching the horn to the rudder
Fit the pushrod connector 25 in the outer hole of the rudder horn
24, and secure it with the washer 26 and nut 27.
Caution: note the correct orientation! Tighten the nut carefully: just
to the point where the connector revolves smoothly, but without
wobbling. When you are sure, apply a tiny drop of cyano to the nut
(best applied on the point of a pin). Fit the socket-head grubscrew
28 in the pushrod connector 25 using the allen key 29.
Apply activator to the horn recess in the rudder, then apply cyano to
the horn 24 and place it in the recess, with the row of holes at the
leading edge, facing the hinge pivot line.
Fig. 14
9. Attaching the horn to the elevator
Fit the pushrod connector 25 in the outer hole of the rudder horn
24, and secure it with the washer 26 and nut 27. Caution: note the
correct orientation! Tighten the nut carefully: just to the point where
the connector revolves smoothly, but without wobbling. When you
are sure, apply a tiny drop of cyano to the nut (best applied on the
point of a pin). Fit the socket-head grubscrew 28 in the pushrod
connector 25 using the allen key 29.
Apply activator to the horn recess in the rudder, then apply cyano to
the horn 24 and place it in the recess, with the row of holes at the
leading edge, facing the hinge pivot line.
Fig. 15
10. Releasing the elevator and rudder
Gently move the rudder and elevator to and fro at the hinge lines to
"ease" the hinges, i.e. to allow them to deflect freely. Do not sepa-
rate the control surfaces.

11. Gluing the tail panels to the fuselage
Offer up the tailplane and fin to the fuselage "dry" (no glue), and
check that they fit correctly. Ensure in particular that the tailplane
10 is a snug fit on the fuselage (no gaps), and is parallel to the
wing saddle at the front of the fuselage. You can check this by
temporarily fixing the tubular wing joiner 40 to the wing saddle
using masking tape. Now sight along the fuselage from the nose
and check that the wing joiner is parallel to the tailplane. When
you are confident that you can align both panels correctly, the
tailplane and fin can be glued permanently to the fuselage; note
that the fin must be set exactly at 90° to the tailplane. Check
alignment and the accuracy of the fit once more before reaching
for the glue. If these parts are mis-aligned, you will regret it for the
whole of the model's life.
