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.

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.
