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 the adhesives stated
in the instructions.
Assembling the model:
1. Attaching the fuselage nose, installing the fuselage liner
shell
Remove any rough edges from the moulded foam
compartments. The first step is to glue the fuselage nose 2 to
the main fuselage section 1: check that the parts fit together
snugly, then spray one side of the joint surface with ZACKI
activator. Allow it to dry for two minutes, then apply "Medium
Zacki" to the other surface, and push the parts together. Cut
out the vacuum-moulded liner shell 10 along the moulded-
in lines, and cut away the whole of the underside at the rear
end to allow the cables to pass through. Temporarily install
the liner shell, and fit the canopy 5 and the fuselage top
decking 6 to check that it is possible to close the hatches fully;
trim the liner shell as required. Glue the liner shell in place
using contact cement, using no more adhesive than is
necessary. Contact cement attacks the plastic of the liner shell,
and too much adhesive may distort and ruin it. Contact
cement is usually allowed to air-dry before joining the parts,
and this procedure is described in the printed instructions,
but for this joint just use it as a conventional glue. Tape the
parts together while the contact cement is drying. You may
need to pack out the liner shell from the inside to hold it in
position.
2. Preparing the wiring
The kit includes the power cables 37 used to connect the
electric motors 36. Using a small round file or a screwdriver,
push a hole through the fuselage sides to extend the cable
ducts in the wings, so that the motor and servo cables can be
passed through as shown in the drawings.
3. Releasing the elevons, installing the horns
For production reasons, and to prevent transit damage, both
elevons (control surfaces) are supplied still attached to the
wings. Cut through the elevon at the root end using a small
fine-bladed metal-cutting saw (for a clean cut). At the tip end
you can cut the elevon free using a sharp balsa knife. The
decal sheet strip designed to act as the aileron hinge has
proved to be less than ideal due to the special characteristics
of the ELAPOR foam used for this model. We recommend that
you use clear thin adhesive tape (e.g. diamond tape) instead.
Prepare the glue-fitting horns 32 for installation in both
elevons: fit the pushrod connector 33 in the outermost 2.5
mm Ø hole, and secure it with the washer 25 and nut 34.
Spray the horns with "Zacki Activator" and allow it to dry for a
while. Apply "Medium Zacki" to the horn recesses, and push
the horns into place. Allow the glue to set hard.
4. Installing the servos and motors.
The model is designed for MULTIPLEX MS-X3 servos. Each
servo lead has to be soldered directly to the servo extension
lead with separation filter # 8 5255. The extension leads are
prepared as follows:
Loop the servo extension lead through the ferrite ring eight
times; when you have finished, the distance from the ring to
the receiver should be 5 to 10 cm. Starting from inside the
fuselage, run the cable through the pierced hole in the
fuselage side in the direction of the servo well. Make a wire
hook, or re-shape a paper clip to help you pull the servo leads
through the foam. Solder the wires together, taking care to
maintain the colour coding, and insulate each joint with a
piece of heat-shrink sleeving. Now temporarily switch on the
RC system and centre the sticks and trims, so that you can be
sure that the servo output arms are at neutral.
Shrink a piece of heat-shrink sleeving round each servo, or
wrap the servos in tape.
The tape or sleeving prevents glue penetrating into the
servo case - and especially into the gears - when the servos
are glued in place.
Now apply "Zacki Activator" to the prepared servo, and allow
it to dry for a couple of minutes. Apply an adequate quantity
(but not too much) of "Medium Zacki" to the servo well, but
only in the area where the tape or sleeve round the servo will
make contact. Place the servo in the servo well, then run the
cable along the cable duct. If necessary, apply clear tape over
the top of the ducts to prevent the wires slipping out.
Locate the pre-formed pushrods 30 and connect the Z-bend
to the outermost hole in the servo output arm. At the elevon
end slide the pushrod through the pushrod connector and
secure it with the M3 socket-head grubscrew 27 using the
allen key 26; remember to set the elevon to neutral before
you tighten the screw.
Connecting the motors
In the same way, run the motor power leads through the cut-
away area of the battery cradle (liner shell) 10 to the motors,
starting from inside the fuselage, and route them along the
motor cable ducts. Fit the insulating sleeves 39 on the pins of
the 47 nF capacitors to guard against short-circuit, then solder
the capacitors across the motor terminals. Cut the power
cables to length, strip the insulation from the ends and solder
them to the motor terminals. As the motors are required to
operate in "pusher mode" , they must be connected with
reversed polarity to make them run backwards, i.e. red to black
(-), and black to red (+).
The Twin-Jet's propellers 35 operate in pusher mode, so for
this application they have to be turned round inside the
spinner; i.e. the plain (non-inscribed) face of the propeller
should face the motor. Fix the propeller to the motor shaft
