Important note
This model is not made of styrofoam™, and 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 assembling the model
Please check the contents of your kit.
You will find Figs. 01 + 02 and the Parts List helpful here.
Assembling the model:
2. Piercing the cable ducts through the fuselage
Use a bradawl, a round file or a screwdriver to pierce the
cable holes through the fuselage: this is done by placing
the model on its back and twisting the tool into the fuselage,
working from the end of the cable duct. Remove all loose
foam particles. Fig. 03
3. Remaining preparation work
The next step is to prepare the glue-fitting horns 24 for
fitting in the control surfaces. Fig. 04
Fit the pushrod connector 25 in the outermost hole in the
horn and secure it with the washer 26 and nut 27. Check
that the connectors swivel smoothly, but without slop.
Caution: secure the nuts with a tiny drop of paint or cyano
to prevent them shaking loose, using the point of a pin to
apply it.
Fit the socket-head grubscrews 28 in the pushrod
connectors.
Spray activator on the base of the horns 24 and allow it to
air-dry. Apply cyano to the horn recesses in the elevons,
and press the horns into place.
Caution: drops of glue may be forced out of the joint - wear
protective goggles to be on the safe side!
4. Installing the servos
The model is designed for MULTIPLEX Nano-S servos. The
servo leads have to be soldered directly to the servo
extension leads (with integral separation filters), # 8 5253:
cut off the servo lead close to the connector, and solder the
wires to the bare ends of the extension lead, soldering like
colours together. Insulate each soldered joint with a
separate heat-shrink sleeve.
Set the servos to centre from the transmitter, or use a servo
tester. Fit the output arms on the servos at 90° to the case
sides. Wrap adhesive tape round each servo, or shrink a
heat-shrink sleeve round the case.
This is intended to prevent adhesive getting inside the
servo, where it could jam the servo gearbox.
Spray activator on the prepared servo and allow it to air-dry.
Apply thick cyano to the servo recess - don't be too sparing,
but don't overdo it, either. Caution: apply the adhesive
only where the servo is protected by the tape or heat-
shrink sleeve. Place the servo in the recess and press it
into place. Run the cable along the servo duct and apply
clear tape over the slot to prevent it falling out. Fig. 05
5. Freeing the control surfaces
Cut through the tip end of the elevons using a balsa knife,
leaving a gap about 1 mm wide. Move the panels to and fro
repeatedly at the hinge line to free up the hinges. Take
care not to over-stretch the hinge line, and do not cut off
the control surfaces! The working range should be about +/
- 45°. Fit the pushrod 30 through the pushrod connector
25, hold the elevon at the neutral position, and tighten the
clamping screw 28 in the pushrod connector. Figs. 06 + 07
6. Installing the wing spar
Slide the tubular GRP spar 10 through the fuselage from
one side and set it exactly central. Don't glue it in place at
this stage. Fig. 08
7. Gluing the outboard wing panels to the centre
section
Trim the outboard wing panels to fit against the centre
section, and glue them in place using cyano. Production
tolerances may produce slight differences in thickness at
the joint, but hand-pressure is sufficient to compress the
foam to the correct thickness; make any adjustment
required before you glue the joint. The spar can now be
glued in place permanently. Deploy the servo cables and
run the extension leads into the fuselage. Seal the cable
ducts with clear adhesive tape as already described. Secure
the servo leads inside the fuselage so that they do not get
in the way when you have to change the flight battery.
Fig. 08
8. Gluing the spar
Check carefully that the wing is straight and free of warps.
The GRP spar 10 should be an easy fit in its slot; it must
not be tight. Apply thick cyano along the length of the spar,
then spray activator over the joint. Allow the adhesive to
cure for a few minutes before placing any load on the wing.
9. Elevon pushrods
Connect the pre-formed end of the pushrods 30 to the
innermost hole in the servo output arms. At the elevon end
slip the pushrods through the pushrod connectors 25 and
tighten the socket-head M3 grubscrews 28 using the allen
key 29; hold the elevons at neutral when you tighten the
grubscrews.
Trim the servo fairings 31 to fit in both wing panels. They
can be glued in place with cyano if you wish, but it is better
to use a few short strips of clear adhesive tape, as you
may need access to the servo for maintenance. Fig. 09
10. Installing the canopy latch clips
Spray activator in the latch clip recesses in the fuselage
and allow it to air-dry. Apply cyano to the canopy latch
clips 22 and push them into position. Fig. 10
11. Fitting the fuselage turtle deck
Trim the fuselage turtle deck 4 to fit, together with the canopy
5. Mark the position of both parts, then glue the turtle deck
4 to the fuselage 3. Fig. 11
