1. Before assembling the model
Check the contents of your kit.
You will find
Figs. 1 + 2
and the Parts List helpful here.
2. The fuselage
The first step is to glue the canopy latches
22
and the motor
mounts
35
to both fuselage shells, fitting the fore-and-aft motor
mount supports
42
at the same time.
Fig. 3
3. Servo installation
Trial-fit the rudder and elevator servos in the fuselage shells
3
+ 4
, then secure them with a drop of glue applied to the servo
mounting lugs. Fix the servo leads to the fuselage sides using
paper masking tape, so that the wires and connectors cannot
cause damage, and do not get in the way when the fuselage
shells are joined later.
Fig. 4
4. Snakes
Prepare the control “snakes”
53 - 54
as follows: cut the outer
and inner tubes to length if necessary, slip the inners inside
the outers and insert the steel pushrods
51 - 52
. Connect the
pushrods to the servos, position the snakes in the channels
as shown, and glue them in place. Hold the fuselage shells
on a flat surface so that they cannot distort.
Figs. 5 + 6
5. Wing screw supports
Clip the wing screw supports
33 + 34
together, and apply glue
to the joints; you may need to use combination pliers for this.
Insert the prepared wing screw supports in the right-hand
fuselage shell, and glue them in place.

6. Installing the aero-tow mechanism
Glue the aero-tow mechanism
40
in the channel in the fuselage
insert
5
using cyano.
If you don’t wish to install the aero-tow mechanism until later,
you must take care not to allow glue to get onto the fuselage
insert
5
when you join the fuselage shells. To fit the aero-tow
servo subsequently, slide a balsa knife down the sides of the
insert and cut through the lateral locating pieces; the insert
can then be removed upwards, allowing you to install the aero-
tow mechanism and release servo.
To operate the aero-tow mechanism you will need one addi-
tional Tiny-S servo; the servo can be installed now, or at any
subsequent time.
Locate the aero-tow release pushrod
41
(1 mm Ø spring steel
wire), and connect the Z-bend to the innermost hole in the
servo output arm. Slide the servo into the recess in the fuselage
insert.
Set the servo to the “closed” end-point, and shorten the
pushrod where it projects out of the tow mechanism; round off
the cut end using fine abrasive paper.
Fit the fuselage insert
5
in the left-hand fuselage shell
3
, and
glue it in place.
Figs. 8 + 9
7. Joining the fuselage shells
Place one of the flat undercarriage supports
67
in the right-
hand fuselage shell, and offer up the shells to each other “dry”
(no glue). When you are sure that everything fits accurately, the
shells can be glued together. Check that the fuselage remains
perfectly straight while the glue is curing.
Figs. 10 + 11
8. Tailwheel unit
Assemble the tailwheel unit as follows: fit the 26 mm Ø wheel
72
and two collets
73
on the steel wire tailwheel axle
71
, and
secure the collets using the socket-head grubscrews
74
(M3 x
3 mm).
The tailwheel axle is attached to the tailwheel unit
70
using
two more collets
73
. Please note: fit the upper collet without its
grubscrew initially, then set the tailwheel steering lever
76
to
the correct position when viewed from above. With all the parts
aligned correctly, tighten the long grubscrew
75
through the
slot in the tailwheel steering lever
76
to connect all the parts.
Fit the swivel pushrod connector
77
in the hole in the tailwheel
steering lever
76
, and secure it with the washer
78
and the nut
79
. Secure the nut with a tiny drop of cyano.
Fig. 12
9. Main undercarriage
The first step here is to attach the wheels and axles to the
aluminium main undercarriage unit.
Fit the following parts loosely onto the M4 socket-head screw
62
: the washer
65
, the lightweight wheel
61
, a second washer
65
and the nut
63
. Now locate the wheel axle holes in the main
undercarriage unit
60
and insert this assembly into one hole;
secure it with the self-locking nut
64
, and tighten the locknut
63
on the other side. Repeat the procedure with the second wheel.
Fig. 13
10. Installing the main undercarriage
The “undercarriage support with nut sockets”
66
can now be
installed in the fuselage. Position the second flat undercarriage
support
67
on the underside of the fuselage. The main
undercarriage unit
60
should now be attached to the fuselage
using the four M3 screws
68
, which pass through parts
67
and
are secured to the undercarriage support
66
using the four
nuts
69
.
Fig. 14
11. Releasing the ailerons and rudder
The control surfaces are supplied still attached to the wing
panels
7 + 8
and the tailplane
12
by means of one or two small
recessed lugs. The particle foam itself acts as the hinge - no
additional hinge tape or similar is necessary. Remove the lugs
by making two parallel cuts spaced about 1 mm apart using a
balsa knife. Flex the control surfaces repeatedly up and down
in order to free up the hinge.
Caution
: take care not to separate
the control surfaces from the wing or tailplane at the hinge
axis.
You may find that odd foam particles are missing along the
hinge line; this is of no consequence, and is not grounds for
complaint.
Fig. 15
12. Preparing the swivel pushrod connectors
Fit the elevator and rudder pushrod connectors
25
in the
outermost hole of the horns
24
and secure them with the
washers
26
and nuts
27
.
Caution
: note the correct orientation
of the connectors. Tighten the nuts carefully, ensure that the
connectors swivel smoothly, then apply a tiny drop of cyano (on
a pin) to prevent them shaking loose. Fit the socket-head
grubscrews
28
in the pushrod connectors
25
using the allen
key
29
.
Figs. 16 + 17
Fit the pushrod connectors
25
in the second hole from the
outside of the aileron horns
24
and prepare them as described
above.
Caution
: 1 x left, 1 x right.
