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).
1. Before you start building
Check the contents of your kit.
You will find Fig. 1 and the parts list helpful here.
Assembling the model:
2. Preparing the wiring
This stage varies according to the version of the kit you
are building. In the standard version the motor must be
suppressed by fitting three capacitors 38, as shown in
Fig. 2. If you are using the MPX 400 round controller,
additional suppression measures are not necessary.
3. Forming the cable tunnels in the fuselage
Using a small bradawl or a screwdriver, push holes
through the fuselage sides to accept the cables. This is
done by laying the model on its back and twisting the
bradawl through the foam, starting from the inboard end
of the cable duct. Remove loose foam particles. Fig. 3
4. Further preparation
Prepare the glue-fitting horns 24 for installation in the
control surfaces.
There are two variants depending on the accessory pack
in your kit:
1. Pushrod connector Fig. 4
2. Articulated pushrod connector Fig. 5
Variant 1), see Fig. 4
Fit the pushrod connector 25 in the innermost 2.5 mm Ø
hole in the horn, and secure it with the washer 26 and nut
27.
Caution: Apply a drop of paint or cyano to the nuts to
prevent them working loose. Use a pin to apply the
adhesive to avoid it jamming the pivot.
Fit the socket-head grubscrew 28 in the connector.
Variant 2), see Fig. 5
Fix the articulated pushrod connector 25 to the innermost
hole in the horn using the M1.6 x 4 mm countersunk screw
27. Tighten the screw to the point where the pushrod
connector still just rotates freely, but does not wobble. Fit
the socket-head grubscrew 28 in the pushrod clamp 26,
and snap the clamp 26 into place.
Spray the horns 24 with Zacki activator and allow it to air-
dry. Apply Medium Zacki to the horn recesses, and press
the horns into place. Allow the glue to set hard.
Caution: pushing the horns into place may cause glue to
squirt out - wear goggles to be on the safe side!
5. Fitting the canopy latch retainers
Spray activator on the appropriate areas inside the
fuselage and allow it to air-dry. Apply Medium Zacki to
the canopy latch retainers 22 and install them as shown
in Figs. 6+7.
6. Cut the vacuum-moulded bottom fairing 6 to size
and trim it to fit. Spray activator on the underside of the
front part of the fuselage and allow it to air-dry. Apply
Medium Zacki to the bottom fairing 6 and place it on the
fuselage. Fig. 8
7. Installing the servos
The model is designed for MULTIPLEX
Each servo lead has to be soldered directly to a 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 hook from wire or 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 air-dry. 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.
Figs. 9+10
Connect the pre-formed end of the pushrods 30 to the
outermost hole in the servo output arm. You may wish to
use one hole further inboard if you prefer your models
less "hot". At the elevon end slip the pushrod through the
pushrod connector 25 and tighten the M3 socket-head
screw 28 using the allen key 29. Check that the elevons
are at neutral before you tighten the screws.
Trim the servo well covers 7 to fit over the servos on each
side. Fix them in place using a little Medium Zacki, or -
better - short strips of clear adhesive tape, as this provides
access to the servos for maintenance. Fig. 11
8. Installing and securing the motor
Trim the vacuum-moulded motor mount 8 to fit and glue it
to the fuselage using Medium Zacki Fig. 12. Position the
motor and secure it using the cable ties 31. Slot the cable
Nano-S
servos.
