Working with Zacki ELAPOR®
Zacki ELAPOR® has been developed specifically for glued joints in our models which consist of moulded ELAPOR®
foam parts.
Please observe the following points in order to obtain perfect joints:
• Avoid the use of activator. ‘Kicker’ significantly weakens the joint. We advise leaving joined parts for 24 hours to obtain
maximum strength, particularly when the glued area is large.
• Activator should only be used for temporary, small-area joints (‘tacking’). Spray a little activator on one surface, and
allow it to air-dry for about thirty seconds.
• To obtain maximum joint strength you should lightly sand the surface with 320-grit abrasive paper before applying glue.
Bent parts - actually don’t exist. If you find that a component has taken up a curve, perhaps after being trans
-
ported, it is easy to straighten again. In this respect ELAPOR® behaves in a similar way to metal: bend the
component back slightly beyond the correct position, and the material will then spring back to its proper shape
when released, and maintain it. There are limits, however - don’t overdo it!
Bent parts - really do exist.
If you wish to paint your model, apply MPX Primer # 60 2700 to the surfaces, wiping it on
very lightly as if you were cleaning the model. Paint must always be applied
thinly and evenly
, otherwise the component
will warp. Then you really will have bent parts, and they will also be heavy and perhaps even unusable. We have found
that matt-finish paints produce the best visual effect.

Note:
Please separate the pictorial pages from the centre of the building instructions before you start construction.
Tuning firewall
The
carbon firewall (motor bulkhead) # 33 2609
is machined from high-quality carbon fibre sheet material, and is
fitted with accurately made aluminium threaded inserts. If you intend to install this bulkhead, please note that a drop of
thread-lock fluid must be applied to the four thrustline adjustment screws (sidethrust and downthrust) once the correct
settings have been established.
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.
2. Preparing the fuselage
To improve orientation in flight it is advisable to paint the
dummy canopy of the fuselage 3 a dark colour, and this is
the best time to do it: mask off the canopy area with adhesive
tape, and start by applying a thin coat of MULTIPLEX MUL-
TIprimer
# 60 2700
. Wipe the primer off after application,
then finish the job with MULTIPLEX ELAPOR Color Spray
paint, e.g. grey
# 60 2710
. Apply the paint is sparingly as
possible; several very thin coats are best.
3. Preparing the elevator
Pack up the elevator
9
on the workbench (e.g. using two
books of the same thickness), so that it lies completely flat.
Glue the CFRP spar
16
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
.

Prepare the elevator horn

as shown in

before
gluing it in the recess in the elevator
9
. Secure the hexagon
nut with a drop of glue.
4. Preparing the rudder
Use a balsa knife to cut the slots for the hinges
22
along
the centreline of the rudder leading edge.

as shown in
