1. Before assembling the model:

Please check the contents of your kit before you start construction.
You will find

Figs. 01 + 02

and the Parts List helpful here.

2. Right / left fuselage shells

The moulding process leaves bridging lugs at the front of the
fuselage shells

4 + 5

, which should now be removed using a

sharp balsa knife.

Fig. 03

Examine the air intakes, and remove any rough edges from the
lips using a very sharp knife. If this leaves areas of a different
colour, touch them in with a soft pencil.

3. Gluing the nose section to the fuselage shell

Trial-fit the fuselage nose

and the right-hand fuselage shell

then glue the parts together using cyano. Take care to line the
parts up accurately.

Fig. 04

4. Installing the fuselage stiffener

Glue the GRP rod

in the fuselage shell using cyano. Glue the

rod over its full length, but don’t apply so much cyano that it is
forced out of the joint.

6. Installing the elevator servo

The elevator servo can be glued in its recess using two drops of
cyano or hot-melt glue. Be sparing with the adhesive, otherwise
it may be difficult to remove the servo again if it should require
repair at any time. Too much adhesive can also penetrate the
servo case, with the danger of jamming the gearbox.
Deploy the servo lead in the channel provided. If you are using
an extension lead with a plug-in connection, cut a small recess
in the fuselage for the connectors. If you have soldering facilities,
it is always preferable to solder the connections.
The lead crosses over the slot for the impeller support.

Secure the loose cable with adhesive tape so that it does not get
in the way during the following procedures.

7. Trim ballast

If you use the recommended components, you will need to glue
the two ballast weights

in the space provided at the tail end of

the fuselage. If lighter batteries become available in the future,
you may be able to take the weights out again; you can remove
one ball for each 20 g saved at the battery compartment position.

8. Aileron servo lead

Glue the extension lead to the inside of the fuselage, with the
socket flush with the outside surface, so that the aileron servo
lead can be plugged in later when the wings are fitted.
Use a sharp knife to cut a small void opposite the socket to
provide space for the servo plug. Unfortunately this void cannot
be produced during the manufacturing process for technical
reasons.

9. Gluing the nose section to the fuselage shell

Trial-fit the fuselage nose

and the right-hand fuselage shell

then glue the parts together using cyano. Take care to line the
parts up accurately.

Glue the GRP rod

in the fuselage shell using cyano. Glue the

rod over its full length, but don’t apply so much cyano that it is
forced out of the joint.

13. Joining the fuselage shells

Start by trial-fitting the fuselage shells ”dry” (no glue); they should
fit together snugly, without requiring force and without being under
tension. If there is a tight spot at any point, trim the parts where
necessary before gluing the shells together using thick cyano.
You will have a few minutes to get everything right, so work swiftly
but not hurriedly. Join the fuselage shells, immediately line them
up correctly, and hold the parts together until the glue starts to
set. Do not resume work on the fuselage for a few minutes as
the adhesive takes some time to cure properly.

14. Aileron horns

(both ailerons)

The aileron horns

are prepared and installed as shown in

the illustration: 1 x left + 1 x right. Tighten the nuts

only lightly,

as the swivel pushrod connectors

must turn smoothly. Secure

the nuts with a tiny drop of paint or glue.

Caution: only apply the paint or glue to the outside of the nut
and the stub of the thread.

Glue the horns in the aileron recesses.

15. Installing the servos and pushrods

(both ailerons)

Check from the transmitter that the aileron servos work correctly,
and set them to centre. Fit the output levers on the servo shafts,
ensuring that the arms project out of the wings (see illustration).
Fit the servo arm retaining screws. Fix the servos in their recesses
with a few drops of cyano or hot-melt glue. Connect the aileron
pushrods

and adjust them.

Fig. 17

16. Freeing the ailerons

(both ailerons)

Carefully release the ailerons by cutting along the marked lines;
the slots should be about 1 mm wide. You will need a very sharp
knife to cut the foam cleanly.

Fig. 18

17. Gluing the wing panels 10 + 11 to the fuselage, connecting
the aileron servos

First connect the aileron servo leads (in the wings) to the
extension leads which you have already installed in the fuselage.
Leave the leads loose in the channels. Glue the wings to the
fuselage, taking care not to glue the cables. Align the wings
carefully before allowing the glue to cure.
