1. Before assembling the model
Please check the contents of your kit before you start working
on it.
You will find Figs. 1 + 2 and the Parts List helpful here.
2. The fuselage
The first step is to glue the canopy latches 22 and the motor
mounts 37 to both fuselage shells.
Fig. 3
3. Installing the servos
Trial-fit the "rudder" and "elevator" servos in the fuselage shells
3 + 4, and secure them with a drop of glue at each mounting
lug. Fix the servo leads in place with paper masking tape so
that the leads and plugs cannot cause damage, and do not
get in the way when the fuselage shells are joined
subsequently.
Fig. 4
4. Control snakes
Prepare the snakes 54 / 56 and 55 / 57 as follows: cut the outer
and inner sleeves to length if necessary, and slip the steel
pushrods 52 / 53 into them. Connect the pre-formed end of the
pushrods to the servos, position the snakes carefully and glue
them to the fuselage. Note that the pre-formed pushrod ends
should be connected to the innermost holes in the servo output
levers. Lay the fuselage shells down flat when gluing the
snakes in place, otherwise there is a chance of distorting the
fuselage.
Figs. 4 - 6
5. Preparing the wing screw supports
Snap the wing screw support components 33 + 34 together
and glue the joints; use a pair of flat-nose pliers to join them if
necessary. Glue the prepared wing screw supports in the right-
hand fuselage shell as shown.
Fig. 7
6. Joining the fuselage shells
Join the fuselage shells 3 / 4 "dry" (without glue) initially, and
check that everything fits properly before gluing the shells
together permanently. Check that the fuselage is perfectly
straight before allowing the glue to set hard.
Fig. 7
7. Preparing the pushrod connector
Fit the swivel pushrod connector 25 for the elevator 8 in the
outer hole in the elevator horn 24, and secure it with the was-
her 26 and the nut 27. Caution: be sure to fit the connector on
the correct side of the horn (see illustration). Tighten the nut
carefully: the pushrod connector must swivel smoothly, but
without undue slop. Apply a tiny drop of cyano or paint to the
threads (on the point of a pin) to prevent the nut working loose.
Fit the socket-head grubscrew 28 on the allen key 29, and use
it to fit the screw loosely in the pushrod connector 25. Glue the
horn 24 in the elevator 8 with the row of holes facing forward.
Fig. 8
8. Gluing the tailplane to the fuselage
Place the tailplane on the fuselage and check that it can be
positioned and aligned correctly; carry out any minor trimming
required. Glue the tailplane to the fuselage and hold it in
position while the adhesive hardens.
Fig. 9
9. Fin and tailwheel
Fit the wire tailwheel unit 76 through the glue-fitting tailwheel
bush 36, then through the glue-fitting rudder horn 35. Bend the
18
end over at 90° as close to part 35 as possible, as shown in
Fig. 10.
Glue the rudder horn 35 in the rudder, but apply cyano to the
underside only. Allow the glue to set hard, then cut a slot about
1.5 mm deep for the tailwheel unit above the horn.
Wipe away excess adhesive if necessary. Position the wire
tailwheel unit 76 over the horn 35, align the parts and glue
them together using plenty of cyano. Allow the glue to cure,
then attach the swivel pushrod connector to the horn. Secure
the retaining nut with a drop of paint or glue. Fig. 11
Fit the tailwheel 77 on the axle: first push one metal wheel
retainer sleeve 78 on the wire, then the wheel, followed by the
second retainer sleeve. Secure each sleeve 78 with a drop of
cyano.

10. Gluing the fin to the fuselage
Trial-fit the prepared fin in the slots in the fuselage and tailplane,
and glue it in place.
Fig. 13
11. Main undercarriage
Prepare the main undercarriage 70 as follows:
Fit socket-head grubscrews 73 in the four wheel collets 72,
and secure the wheels 71 on the undercarriage by fitting a
collet on each side of each wheel. Check that the wheels rotate
freely, then tighten the grubscrews. Fig. 15
The plastic undercarriage bracket 74 can now be installed in
the fuselage: first press it into position, then apply glue all
round it. Fig. 14
Allow the undercarriage 70 to snap into position in the bracket,
then fit the retainer screw 75 to secure it.
Fig. 15
12. The wings
The wing panels 6 / 7 should not be glued together!
Trial-fit the wing spars 50 / 51 and the spar holders 30 / 31 as
shown in the illustration.
Note: the front spar holder 30 is taller than the rear holder 31.
When you are sure that everything fits properly, glue the spars
50 / 51 and the spar holders 30 / 31 in the right-hand wing
panel only. Fig. 16
Now insert the second pair of spars in the free end of the spar
holders (do not use glue!). Slide the left wing onto the spars
and holders and check that they fit correctly. Apply glue to the
spar channel in the left wing and position it accurately on the
spars. Fig. 17
If you have done everything correctly, you will now be able to
part the wing panels in the centre once the glue has set hard.
13. Trial assembly
The wings are held on the fuselage using the plastic screws
32. The locating blocks moulded into the underside of the
wing prevents the wing slipping off the fuselage or out of
position.
