Multiplex Xeno Notice De Construction page 13

Like every aircraft, the airframe strength of the Xeno has its limits. Extreme dives and senselessly violent manoeuvres can
result in the loss of the model. Please note: in such cases we are not prepared to exchange the model. We urge you to fly gently
at first, and work your way gradually towards the aeroplane's limits. The Xeno is designed to accept our Tuning (upgrade)
power set, but is only capable of withstanding the loads on the airframe if built exactly according to the instructions, and if
flown in an undamaged state.
Please note: the model is subjected to the most severe loads when dived with the propeller folded.
Important note
This model is not made of styrofoam™, and it is not possible to glue the material using white glue, polyurethane or epoxy;
these adhesives only produce a superficial bond which simply gives way when stressed. Please use medium-viscosity
cyano-acrylate glue exclusively, preferably our Zacki-ELAPOR®, # 59 2727 - the cyano glue optimised specifically for
ELAPOR® particle foam. At some points you will also need the extremely low-viscosity version of the adhesive: Zacki
ELAPOR super liquid, # 59 2728.
If you use Zacki-ELAPOR® you will find that you do not need cyano kicker or activator for most joints. However, if you
wish to use a different adhesive, and are therefore obliged to use kicker / activator spray, we recommend that you apply
the material in the open air to avoid health problems.
1. Before assembling the model
Please check the contents of your kit before you start working on
it.
You will find Figs. 01 + 02 helpful here, along with the Parts List.
2. Preparing the fuselage cradle
Apply Zacki ELAPOR to the hinge leaves 22, and push them fully
into the slots in both fuselage cradle shells 20 and 21. See Fig.
03
3. Trimming and joining the fuselage cradle
The wing panels fit inside the root ribs of the fuselage cradle
shells 20 + 21; you may find it necessary to compress the Elapor
foam slightly with your fingers to produce a neat fit. Check very
carefully dry - without glue - that everything fits as it should.
Fig. 04
Remove the cradle shells from the wings again.
Fit the hinge pin 41 through the hinge leaves. Apply Zacki
Elapor to the root face of both wings panels, then push the
wings together firmly and briskly, pressing them fully home
into the root ribs of the cradle. Check immediately that the
foam parts line up correctly with the plastic parts, and ensure
that there are no gaps along the joint lines - especially at the
nose. Leave the glued joints to cure completely before
resuming work on the model.
Fig. 05
This stage is completed by carefully running Zacki Elapor su-
per liquid along the edges between the fuselage cradle 20 +
21 and the foam, flexing the foam away from the plastic slightly
to allow the glue to penetrate. Allow the glue to set hard, then
withdraw the hinge pin 41 again before proceeding.
4. Completing the wings
- All joints should be completed using Zacki ELAPOR.
Trial-fit the spars 42 in the slots in the underside of both wing
panels. When you are satisfied, glue them in place, taking
care to apply adhesive along their full length. Wipe away
excess glue immediately.

Glue the left and right fin supports 28 and 29 in the recesses
in the underside of both wings.
Fig. 07
Position the fin retaining clips 27 carefully, and glue them in
the recesses.
Fig. 08
Glue the fin holders 26 to the left and right fins; note that the fins
are identical. As you will already have noticed, the fins are very
easily removed for transport.
Fig. 09
Install the swivel pushrod connectors 12, 13, 14 and 15 in the
outermost hole in the elevon horns 30. Glue the horns 30 in the
elevons (elevon = combination of elevator and aileron). The row
of holes must face the servo.
Fig. 10
5. Installing the servos
The model is designed for MULTIPLEX Tiny MG servos. These
are robust metal-geared servos at a reasonable price; they have
been tested in the model, and are strongly recommended. You
will also find that the servo leads are the correct length as
standard. If you prefer to use different servos, you may need to
adjust the installation wells and purchase extension leads.
Fit the servos and glue them in place with a drop of Zacki ELAPOR
at each mounting lug. Deploy the servo leads along the cable
duct, and route the connectors into the internal space in the
fuselage cradle. Seal the cable wells with adhesive film.
Fig. 11
6. Elevon pushrods
Connect the Z-bend of the elevon pushrods 40 to the outermost
hole in the servo output arms (approx. 12.5 mm from the hinge
pivot axis). Set the servo output arms at right-angles to the servo
case, and connect the pushrods to the swivel connectors
mounted on the elevon horns. Tighten the clamping screws,
and secure the nuts and screws with a drop of thread-lock fluid
or glue.
Release the elevons at both ends! Fig. 12
7. Servo fairings
The final step in this stage is to install the servo fairings 31 + 32.
The fairings are simply glued in place with one or two drops of
cyano glue, as they can easily be removed again at any time if
required.
Fig. 13
8. Preparing the canopies
Attach the canopy latches 24 + 25 to the canopy (glider canopy
23 and / or the power canopy - included in the Power Set). Glue
the latches in place with a little cyano.
