Important note
This model is not made of styrofoam™! It is not
possible to glue the material using white glue or
epoxy. Please be sure to use cyano-acrylate glue
exclusively, preferably in conjunction with cyano
activator (kicker). For all joints use medium-
viscosity cyano-acrylate (“cyano”), e.g. “ZACKi
medium viscosity”. When gluing Elapor ® always
use this procedure: spray one surface with
activator, allow it to air-dry, then apply cyano
(ZACKi) to the other side. Join the parts and
position them accurately immediately.

Please take care when working with cyano
adhesives. These materials harden in
seconds, so do not allow them to get onto
your fingers or other parts of your body. It
is important to wear goggles to protect your
eyes. Keep the adhesive out of the reach of
children.

1. Before starting construction

Please check that the contents of your kit are complete.

Assembling the model:

2. Piercing the cable tunnels

Continue the tunnels for the cables

through the

fuselage

and into the engine nacelles using a bradawl

or a round file. This is best done by inverting the model
and twisting the bradawl through, working from the
existing cable duct. Remove all loose foam particles.

3. Assembling the fuselage

Glue the top and bottom parts of the fuselage nose

2 +

together.

Fig. 3

Offer up the joined nose section

2 + 3

to the fuselage

then glue the parts together. Ensure that the edges line
up accurately.

4. Internal fuselage fittings

Install the latch clips

in the fuselage. This is done by

spraying activator in the recesses and allowing it to air-
dry. Apply cyano to the joint surfaces of the latch clips
and immediately place them in position. Add more cyano
if necessary to obtain strong joints. Glue the threaded
bush

in place with cyano.

5. Installing the aileron servos and motors

Trial-fit the servos in the moulded-in recesses. You may
need to make slight adjustments to suit the servos you
are using. Fit the cables through the ducts. Shrink a
piece of heat-shrink sleeving round each servo (or wrap
in adhesive tape), then glue the servos in their recesses.
Note: don’t be tempted to glue the servos in place
without wrapping them in sleeving or tape, as glue can
easily get inside the servo case and ruin it.

Installing the motors:

the motors are fitted with basic

suppressors, but these need to be supplemented for
increased security. This is done by soldering a capacitor

between each motor terminal and the can, and a

third capacitor between the terminals. Fit the motor
power leads through the terminals and solder them and
the capacitors in place at the same time. Check at this
early stage that both motors are set up for “left-hand”
running (clockwise when you look at the motor shaft).

Fig. 6b

. Glue the motors in the fixed part of the nacelles.

Take care not to allow glue to run inside the motors or
into the cooling slots. Check that the engine nacelles
are a snug fit.

6. The wing joiners

Carefully glue parts

and

in place using the method

described above. Take particular care that no glue gets
onto the surfaces which will make contact with the wing
joiners. Be careful here, otherwise you could find that
the model can never be dismantled again. When you
are certain that there is no active adhesive inside the
joiner sockets, check that the wing joiners

are a snug

fit in them.

. Close the wing joiner sockets in the

outboard wing panels in a similar manner by fitting parts

13 + 14

, but this time glue the wing joiners

to the

outboard wing panels

4 + 5. Fig. 8

7. Preparing the pushrod connectors (6 x)

Caution: note the orientation: 2 x left, 2 x right.
Attach the articulated pushrod connectors

to the

outermost hole in the horns

using the M1.6 x 4

countersunk screws

. Tighten the screw just to the

point where the pushrod connector still swivels freely,
but does not wobble. With a little care you will find the
best combination of freedom of movement and lack of
slop. You may need to re-tighten the screw after the
first few flights. Fit the socket-head grubscrew

in the

articulated swivel block

, then snap the swivel block

into the connector housing.

Note: when you need to undo the pushrod connector
again, e.g. for removing the outboard wing, this is very
easily done with the help of a screwdriver (blade width
approx. 4 mm). Slip the screwdriver blade between
connector housing and swivel block and twist it slightly
- the pushrod comes away, and can be re-fitted again
without disturbing the trim.

8. Checking the wing joiner system

Assemble the model using the wing joiners

. Check

that the wings

4 + 5

line up correctly. Trim the parts

carefully if required.

9. Installing the horns, connecting the pushrods

Apply Activator to the horn recesses and slots and allow
it to air-dry. Apply Zacki to the horns and push them
into position. Take care that the pushrod connectors are
on the correct side of the horns! Set all servos to neutral
from the transmitter, connect the pushrods and tighten
the grubscrews on the opposite side to secure them.
