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"). We recommend medium or
high-viscosity (thick) cyano. This is the procedure with Elapor®: spray cyano activator on one face of the joint; allow it to air-dry
for around two minutes until the surface appears to be "dry", then apply cyano adhesive to the other face. Join the parts, and
immediately position them accurately.
Please take care when handling cyano-acrylate adhesives. These materials harden in seconds, so don't get them on

Please check the contents of your kit before you start construction.

2. Preparing the control "snakes"
The first step is to cut the plastic outer and inner snake sleeves
to the lengths stated below. The sleeves are best cut by placing
them on a hard flat surface and rolling them to and fro under the
blade of a balsa knife; the sleeves can then simply be broken off
at the scored points.
3 mm Ø x 2 mm Ø outer snake sleeves
2 x 52 = 300 mm
2 mm Ø x 1 mm Ø inner snake sleeves
2 x 53 = 320 mm
3. Completing the control snakes
Prepare the snakes as follows prior to installing them: slip the
inner sleeves 53 into the outer sleeves 52, and slide the steel
rods 51 into the inner sleeves.
4. Preparing the fuselage shells
The Nano-S servos for rudder and elevator should now be
installed in the fuselage shells 2 + 3. Place the servos in the
recesses, and apply a drop of thick cyano or hot-melt glue to the
mounting lugs to hold them in place.
Fig. 03
Stand the fuselage shells on a flat surface, and connect the pre-
formed end of the steel pushrods (with snake sleeves fitted) to
the servo output arms, using the outermost hole in the levers.
Apply cyano to the snake channels, then press the snakes into
them as far as they will go (press against them from the inside)
until the adhesive has set hard.

5. Installing the motor mounts
The motor mounts 39 (2 x) can now be glued in the fuselage
shells on both sides using cyano. Ensure that the motor mounts
39 are a snug, accurate fit in the foam components before you
apply glue. Sand the joint surface of the plastic mouldings and
glue them in place very securely. The quality of these joints
dictates whether the motor stays attached to the fuselage or not!

6. Canopy latch
Glue the latch catches 22 in the fuselage shells as shown in Fig.
05.

8. Joining the fuselage shells
Temporarily tape the servo leads to the fuselage so that they do
not get in the way when you are joining the fuselage shells. Hold
the fuselage shells 2 + 3 together "dry" (no glue), and check that
everything fits together without requiring force. Apply thick cyano
to one face, join the shells and align them carefully before the
glue starts to set; this normally takes about ten seconds, but
varies according to humidity. Hold the fuselage in your hands for
another two or three minutes, checking continually that it is still
perfectly straight, because the glue takes at least this length of
time to harden sufficiently.

9. Completing the front fuselage hatch and canopy
Insert the latch tongues 23 and set them to approximately the
right position. Fit the front hatch 4 on the fuselage under light
pressure, allowing the tongues to take up their correct position.
Carefully open the hatch, bend the latch tongues 23 slightly to
one side and apply cyano in the gap. Straighten them
immediately, and allow the glue to set hard.
Fig. 09
Repeat the procedure with the canopy frame 5. Check that the
canopy 19 is an accurate fit on the canopy frame, place it on the
fuselage, and fix the canopy to the frame using a few drops of
glue. Let the glue harden, then lift off the canopy assembly and
reinforce the joints with more glue.
Figs. 10 + 11
If you wish, you can cut down the canopy to form a simple
windshield, transforming the "saloon" into an "open-top"
machine.
10. Preparing the tailplane
Move the elevators to and fro to free up the hinges. Attach the
swivel pushrod connector to the elevator horn, and glue it in the
recess in the elevator 12. Secure the nut 27 on the pushrod
connector 25 using a drop of glue.
Fig. 12
11. Gluing the tailplane to the fuselage
Place the tailplane 12 on the fuselage "dry" (no glue), and check
that it is possible to set it exactly central and horizontal. Glue it in
place using cyano, and pin it in the correct position before the
glue sets.
