BUILDING INSTRUCTIONS

Important note:
Always wear protective goggles when using cyano-acrylate glue
('cyano', 'CA'), as the adhesive may squirt out when parts are
pushed together. Use cyano (Zacki ELAPOR®) for all joints on
this model unless stated otherwise. Roughen all joint surfaces
with 320-grit abrasive paper before applying glue.
Note:
You can separate the pictorial pages from the center of the buil-
ding instruction.
1. CHECKING THE KIT CONTENTS
Please check that all parts are present in your kit, by referring to
Figs. 1 and 2 and the Parts List.
2. COMPLETING THE FUSELAGE AND TAIL PANELS
2.1 Preparing the control 'snakes'
Check the length of the elevator inner and outer snake sleeves
51 and 52, and shorten them if necessary.
3 / 2 Ø (O.D. / I.D.) x 785 mm
52
2 / 1 Ø (O.D. / I.D.) x 850 mm
51
Slip the smaller sleeve into the larger sleeve, then fit the steel
pushrod 50 (0.8 Ø x 875 mm) into the inner sleeve.
Repeat the procedure with the rudder snake components:
3 / 2 Ø (O.D. / I.D.) x 785 mm
52
2 / 1 Ø (O.D. / I.D.) x 850 mm
51
50 0.8 Ø x 875 mm
2.2 Installing the snakes in the fuselage shells
Please note: the snake outers 52 are designed to be glued to the
fuselage over their full length. Carrying this out conscientiously
results in a considerable increase in the stiffness of the fuselage.
Check that the snakes run smoothly and freely, and take particular
care to avoid glue running inside the outer sleeves.
Lay the complete elevator snake in the left-hand fuselage shell 4,
with the pre-formed end (Z-bend) at the nose. Position the front
end of the snake outer 52 as shown in Fig. 4.
Lay the fuselage shell down flat, and run cyano between the outer
sleeve 52 and the channel in the outside of the fuselage shell
over its full length.
Figs. 3, 4 and 5.
Repeat the procedure with the rudder snake and the right-hand
fuselage shell 5: position the snake carefully, then glue it in place.
When laying the right-hand fuselage shell down flat, pack it up at
intervals in order to avoid damaging the locating lugs.
2.3 Installing the GRP stiffeners
Glue the GRP stiffener 54 (length 680 mm) in the upper channel
of the right-hand fuselage shell 5, and the GRP stiffener 55 (length
740 mm) in the lower channel of the same fuselage shell. Check
that the GRP stiffeners lie flush with the foam's surface to ensure
that the fuselage shells mate without gaps when joined, then run
glue along their full length. You may need to tape the GRP stiffeners
in place here and there until the glue has set hard.

2.4 Installing the motor mount
The motor mount 39 can now be glued in the right-hand fuselage
shell. Take care not to allow adhesive to run out of the joint; the
exposed half of the motor mount (which will be glued when the
fuselage shells are joined) must be free of adhesive. The motor
20
mount should be installed even if you intend only to fly the Ea-
syGlider as a pure glider (without motor), as it adds strength to
the fuselage.

2.5 Installing the tail mount and the rudder hinge
Check that the tailplane mount 30 and the fuselage-mounted
rudder hinge 34 are a close fit in the appropriate recesses in
the right-hand fuselage shell, and carry out any minor trimming
required. Both parts can then be glued in place. Do not allow any
excess glue to be squeezed out; the exposed halves of these
components should be free of adhesive.

2.6 Gluing the cables in the cable holders
Locate the sockets on the 300 mm servo extension leads (# 8
5031), and glue them in the cable holders 41, flush with the end.
The cables can now be passed through the strain relief lugs.

2.7 Installing the servos in the fuselage shells
The first step here is to remove the output arms from the two Tiny-S
servos, before placing the servos in the left and right sides of the
fuselage shells, as shown in Fig. 10. If you prefer to use different
servos, you may find that minor adjustments are required here.
Fix the servos in place with a drop of Zacki ELAPOR® or hot-melt
glue, applied to the servo lugs where they meet the foam. Glue the
Canopy Lock latches 24 in the right and left fuselage shells. Glue
the cable holders 41 in the appropriate recesses in the fuselage
shells, taking care to keep them flush. Press the cables into the
channels in both fuselage sides, then glue the two fuselage cover
plates 42 in place as shown.
Fig. 10
2.8 Joining the fuselage shells
Use Zacki ELAPOR® adhesive for this stage. The first step is a
'dry run': without applying glue, check that the two fuselage shells
fit together accurately, without gaps, and carry out any minor trim-
ming required. Roughen the joint surfaces of both fuselage shells
using 320-grit abrasive paper. Apply glue to the following areas
of the right-hand fuselage shell 5: all the joint surfaces, including
the motor mount 39, the tail mount 30 and the fuselage-mounted
rudder hinge 34. Now carefully place the fuselage shells together,
check that they fit neatly all round, and align them exactly. It is
important that the fuselage should remain straight - no warps or
twists! Hold the fuselage shells together for a few minutes until the
adhesive has cured fully. When the fuselage shells are joined, glue
one of the two fin end-pieces 38 in place at the tailplane mount.
Fig. 11
2.9 Installing the servo output arms
Having removed the output arms, set the servos to centre (neut-
ral) from the transmitter. Connect the pre-formed Z-bends of the
elevator and rudder snakes to the centre hole in each servo output
arm. Note that the cropped end of the Z-bend should lie underneath
the output arm. Now press the output arms onto the servo output
shafts - not forgetting the retaining screws! Note that the centreline
of each output arm should be angled back slightly, so that it forms
a right-angle (or as close as possible) with the snake pushrod.

2.10 Completing the tailplane
Cut away the foam at both ends of the elevator to free it from
the tailplane 9, leaving a gap about 1 mm wide. Cautiously work
the integral hinge line to and fro to render it free-moving. Do not
separate the elevator under any circumstances!
Now check that the upper tailplane support 32 and the lower
tailplane support 33 fit flush in the appropriate recesses of the
tailplane, and carry out any minor trimming required. Both parts
can now be glued to the tailplane. Take particular care over the
alignment of these parts, as they determine the angle of incidence
