Using 5-minute epoxy (e.g. MULTIPLEX 5-minute resin in dispenser, Order No. 60 2740)
This adhesive should only be used at room temperature. The maximum working time (pot life) is around 5 minutes. For this
reason you should mix up no more than the quantity required for the job in hand. Measure out equal quantities of each
component as accurately as possible, and mix them together quickly and very thoroughly. Apply the glue sparingly to one
side of the joint - don't apply too much. Push the parts together immediately, and tape or weight them together for at least 10
minutes. Fresh adhesive can be wiped off easily with methylated spirit (meths) on a rag while it is still soft. Do not use other
solvents with epoxy, as they could easily damage the styrofoam and ABS components in the kit. Always read and observe
the instructions provided by the adhesive manufacturer.
Assembling the model:
1. Completing and attaching the canopy
The canopy 4 is attached to the fuselage by means of a
rubber band 83 at the front, while the canopy former 41 (2x)
engages under the lip of the turtle deck at the rear.
The first step is to glue together the two canopy formers 41,
taking care to keep them flat and the edges flush. Drill 1.5
mm Ø pilot-holes in the two hardwood dowels 53, screw the
two screw-hooks 88 in them, and secure each with a drop of
cyano.
Glue one dowel / screw hook in the round hole in the canopy,
and wipe away excess glue immediately. Temporarily fix the
canopy to the fuselage using paper masking tape, then glue
the canopy former 41 to the rear face of the canopy, working
from the inside of the fuselage. Take care that no glue gets
onto the fuselage turtle deck. Allow the glue to set hard, then
remove the canopy again.
Cut out the battery cradle 20 along the marked lines using a
pair of scissors, and trim it to fit in the front part of the
fuselage. You will need to squeeze the sides of the moulding
together slightly to ease it into the fuselage. Place the canopy
on the fuselage and check that it still fits correctly. Once you
are sure that everything fits, the battery cradle can be glued
in place permanently: apply a thin coating of 5-minute epoxy
to the joint surfaces in the fuselage and push the battery
cradle into the recess. Hold the cradle in place with strips of
tape, and if necessary push the sides outwards gently with
packing pieces to keep the surfaces in contact until the resin
has cured.
Bend the second screw-hook (for the fuselage) to the shape
shown, using a pair of combination pliers or a vice. Slip a
length of thread through the screw-hook, and glue the dowel
in the recess in the front of the battery cradle 20.
Tie the rubber band to the thread, pull it through the closed
screw-hook, and connect it to the hook in the canopy. The
canopy is fitted as follows: first engage it carefully at the
rear, then allow the rubber band to pull it into position at the
front. Check once again that the canopy fits snugly, and carry
out any trimming required.
At the flying site, when you have to change flight packs, use
this procedure: open the canopy at the front and swivel it
through 90° without disconnecting the rubber band.
Tip: if the rubber band should become slack, "wind it up" or
double it over to increase the tension holding the canopy.
2. Making the loading bay, installing the servo
The loading bay is assembled from the plywood parts 30 to
34. Separate these parts from the die-cut sheet and clean
up the edges carefully.
Trim the opening in the servo former 33 to accept the servo
which operates the loading bay doors, and install the servo.
We recommend the MPX Profi 3BB servo, # 6 5071. Please
note that the linkage and lever lengths for the loading bay
door opening mechanism are specially designed, and the
system works perfectly provided that you change nothing.
If you wish to use a different servo, you should still use the
servo output arm 57, which is supplied in the kit. This lever
has the exact hole spacings required, and it must be used if
the system is to work properly. If the splined socket of the
output lever supplied does not fit your servo, invert the lever
and screw it to the original output arm or disc supplied with
your servo.

Assemble the parts of the loading bay "dry" (no glue): two
side panels 30, front former 31, rear former 32 and servo
former 33. Place this assembly in the fuselage and trim it to
fit if necessary. Drill 2 mm Ø holes in parts 31 and 32 at the
punched points.
When you are sure that everything fits correctly, glue the
parts of the loading bay together carefully using white glue
or 5-minute epoxy. Trim the two door stops 34 to fit inside
the bay, flush with the side panels, and glue them in place.
The loading bay is glued in the fuselage permanently at a
later stage, when the wings have been finished.
The wings are removable for ease of transport.
3. Preparing and installing the control surface horns
Fit a pushrod connector 91 in the outermost hole of the
elevator and rudder horns 82. Fit the M2 washers 92 on the
threaded shank and secure the connectors with the nuts 85.
Fit the M3 socket-head screws 87 in the threaded hole in the
pushrod connectors using the allen key 76.
Remove half of the projecting lug of the rudder horn as shown
in the drawing.
The pushrod connectors should be installed in the innermost
hole of the aileron horns. Note that the aileron horns are
handed, i.e. different left and right.
Before gluing the horns in place, check that the control
surfaces are capable of the stated travels. If not, move the
pushrods to a different hole in the servo output arm to obtain
the stated throws.

4. Completing the tailplane
Trim the elevator joiner 54 to fit in the recess on the underside
of the elevator 5, and glue it in place.
For production reasons, and to prevent transit damage, the
elevator is supplied still attached to the tailplane; it should
now be separated by cutting from the trailing edge forward
to the hinge line. Use a small fine-tooth hacksaw blade (for a
clean cut) and saw neatly through the foam as far as the
hinge line. Cut out the hinge strips from the decal sheet and
apply them along the top of the pivot line, keeping the tape
central over the hinge axis. Carefully move the elevators to
1
and fro until you are sure that they move freely enough. Glue
the elevator horn 82 in the recess as shown.
5. Completing the fin
The first step is to separate the rudder from the fin 6
completely, and then attach it again using the two plastic
hinges 90. Saw from the rudder trailing edge forward to the
hinge line at top and bottom, cutting along the moulded-in
lines. Cut through the hinge line using a sharp balsa knife.
Remove the rudder, cut off any rough spots and sand the
edges smooth. Cut slots in the fin and rudder to accept the
plastic hinges; use a sharp balsa knife, and cut the slots
about 30 mm from top and bottom. Temporarily fit the rudder
on its hinges.
