1. Before assembling the model

Check the contents of your kit before you start working on it.

You will find Figs. 1 + 2 and the Parts List helpful here.

Note: the GRP spars and longerons 40 - 43 are supplied in the

kit as one full-length strip 14, and have to be cut to the correct

length. Please cut them as follows:

40 2 x L.H. and R.H. fuselage longerons 1.3 Ø x 745 mm

41 2 x L.H. and R.H. motor mount supports 1.3 Ø x 120 mm

42 2 x top and bottom wing spars 1.3 Ø x 855 mm

43 2 x top and bottom tailplane spars 1.3 Ø x 400 mm

Alternatively you can cut the strips to the length of the moulded

foam components.

2. Preparing the elevator (9)

Lay the elevator 9 flat on the workbench and weight it down

temporarily. Glue the spars 43 in place, wiping off excess glue

immediately with a cloth. Use a balsa knife to cut slots at the

marked points for the hinges 22.

Fig. 03

Prepare the elevator horn 23 as shown in Fig. 04, and glue it in

the recess in the elevator 9.

3. Preparing the rudder

Use a balsa knife to cut the slots for the rudder hinges 22.

Fig. 05

Prepare the rudder horn 23 as shown in Fig. 06, and glue it in the

slot.

4. Preparing the ailerons (6 + 7)

Here again use a balsa knife to cut slots for the hinges 22 at the

marked points. Fig. 7. Prepare the aileron horns 23 as shown in

Fig. 08, and glue them in the slots; make sure the horns and

swivel connectors are fitted the right way round.

5. Preparing the fuselage 3

To improve the visibility of the model in flight we advise you to

pick out the canopy in a dark colour, and this is easiest to do at

this stage. Mask out the canopy with adhesive tape before

painting; we recommend the use of spray cans. Paint is heavy,

so keep the application of colour as light as possible.

6. Installing the motor mount

Glue the plastic motor mount components 35 + 36 in place as

shown in Fig. 09, followed by the motor mount supports 41 on

both sides.

Fig. 10

7. Installing the fuselage longerons

Lay the fuselage 3 down on a flat bench, with one fuselage

longeron channel facing down, and fit one fuselage longeron in

the longeron channel facing you; run cyano along the joint. Allow

the glue to set hard, then repeat the procedure on the other side

to form a mirror-image.

Fig. 11

Trial-fit the elevator and rudder servos in their recesses in the

fuselage, and secure each with a drop of cyano applied to the

mounting lugs. Deploy the leads forward towards the receiver.

Fig. 12

8. The main undercarriage 13

The first step is to remove any rough edges from the ends of the

wire main undercarriage unit, and check that its shape is exactly

as shown. Fit the first starlock washer 39 on one wheel axle by

laying a pair of pliers on the bench with the jaws slightly open, as

shown in Fig. 13, and pressing the wire unit 13 through the

washer. Once the starlock washer is on the axle you will find that

it can be pushed into final position; the free end of each wheel

axle should be 24 mm long.

Place both undercarriage supports 37 over the wire unit 13 as

shown, slip this assembly into the fuselage from the side, and

glue it in place carefully.

Fig. 14

The first starlock washer can now be fitted on the second wheel

axle, using the pair of pliers again. Now fit the wheels and secure

them with the second starlock washers. Allow the wheels just

sufficient clearance for them to spin freely.

Fig. 15

Now glue the undercarriage leg fairings 11 + 12 in place as

shown, taking care to glue them to the wire legs only; do

not glue

them to the fuselage at the top, as this would restrict the springing

effect of the steel.

Figs. 16 + 17

9. Completing the wing

Glue the wing panels 4 + 5 together at the centre, taking particular

care to ensure that they are not twisted relative to each other.

Fig. 18

Invert the joined wing and lay it down on a flat surface. After the

first third the whole surface of the wing panels should make

contact with the bench surface. Glue the bottom wing spar 42 in

the appropriate channel.

Fig. 19

Turn the wing over, lay

one half-span down flat and weight it

down temporarily. Glue the top spar in the channel of the weighted

wing panel only.

Fig. 20

Allow the glue to harden, then pack up this side by 5 mm at the

tip, and glue the spar to the second wing panel.

Fig. 21

Use a balsa knife to cut the slots at the marked points in the

wings and the ailerons for the aileron hinges 22.

Fig. 22

10. Joining the wing and fuselage

Attach the left-hand aileron 6 to the left-hand wing panel 4 using

the hinges 22. Secure each of the hinges 22 with a drop of

cyano.

Fig. 23

Slide the wing, with one aileron attached, through the fuselage

as shown in Fig. 24. Set the wing central, then attach the second

aileron as shown in Fig. 25. Now position the wing carefully

(square and at right-angles to the fuselage) and run cyano along

the joint between the fuselage and the wing; don’t allow excess

glue to run out of the joints. Check the alignment of the wing

once again, as shown in Figs. 26 and 27.

11. Installing the servos, connecting the control surfaces

Place the aileron servos in their recesses, and secure each with

a drop of glue applied to the mounting lugs. Connect the pre-

formed end of the pushrods 29 to the servo output arms. Slip the

pushrods through the swivel pushrod connectors on the aileron

horns, set the servos and ailerons to centre, then tighten the

clamping screws in the connectors.

Fig. 28

12. Installing the tailplane and rudder

Trial-fit the tailplane 8 in its slot, and check that it is at right-

angles to the fuselage. Carry out any trimming required, then

glue it in place.
