12. Completing the tail panels (KIT+RR)
Glue the elevator fi tting 60 in the elevator 16. Apply a little glue
to the sleeves 112, slip them over the ends of the wire elevator
joiner 113, and glue this assembly in the elevator as shown. Glue
the elevator joiner cover 23 over the top, followed by the elevator
horn 61.
Glue a hinge 92 at the outboard end of the tailplane on each side,
and glue the in-fi ll pieces 16a and 16b over the top to conceal them.
Figs. 55 + 56
Glue the clip-hinges "B" 72 in the rudder 17, and glue the in-fi ll
pieces 18 and 19 over the top. Glue the rudder horn 61 in place,
followed by the tailwheel driver 59.
Figs. 57 + 58
Slide the tailplane into the slot in the tail end of the fuselage 'dry'
(no glue), and check that it sits at right-angles to the fi n. Before
gluing it in place, we recommend that you fi t the wings on the model
and sight along the fuselage from nose or tail to check alignment.
The tailplane can then be glued in place, and again checked for
alignment. Allow the glue to set hard, then clip the rudder hinges
into place: fi rst fi t the bottom hinge spigot, then engage the hinge at
the top. Glue the tailplane struts, consisting of parts 127 and 128,
to the tailplane, again taking care to maintain correct alignment.
Figs. 59 - 63
Attach two swivel connectors 66 to the tailwheel steering lever 44,
securing them with the 2 mm I.D. washers 69 and M2 nuts 70.
Connect the two tailwheel steering springs 58 to the tailwheel driver
59 on the rudder, and attach them to the steering lever 44 using
the M3 x 3 mm grubscrews 68; both springs should be under light
tension, and the tailwheel should line up correctly with the rudder.
Fig. 64
Connect the elevator pushrod 115 and the rudder pushrod 116 to
the servo output arms as shown in Figs. 65 and 66, and mount the
swivel connectors 66, the 2 mm I.D. washers 69 and the M2 nuts
70 on the control surface horns The nuts must be tightened just to
the point where the connector barrels rotate smoothly, but without
any hint of binding. Apply a drop of Zacki to these nuts when you
are satisfi ed. Slip the pushrods through the swivel connectors,
set the servos and control surfaces to centre, and tighten the M3
grubscrews 68 fi rmly.

13. Closing the cargo bay (KIT)
The FunCub XL is prepared as standard for fi tting a radio-controlled
cargo drop bay. This is an optional feature, and can be retro-fi tted
at any time. If you do not wish to fi t working doors, simply close the
cargo bay using the cargo bay bottom panel 22. which is secured
with four magnets 34: two are glued to the bottom panel, and a
further two in the bottom of the fuselage.
CAUTION: it is important to fi t the magnets the right way round,
i.e. the pairs of magnets which come into contact with each other
must attract - not repel! Do not place the bottom panel on the
fuselage until the glue has set hard!
Figs. 67 - 70
14. Installing the cargo bay doors (KIT+RR)
First take the left-hand cargo bay door 20, and glue a magnet 34
in the recess as shown. Glue the square-section CFRP stiffening
rod 129 (2 x 2 x 188 mm) in the long slot.
Fig. 71
Glue the tubular bush 122 for the L-shaped hinge pin 121 adjacent
to the horn recess using Zacki; please take great care to avoid
adhesive running inside the tube! The L-shaped pin is set upright,
and pushed forward later when the door is fi tted. The door is locked
in place by folding the L-shaped pin down until the magnet traps it.
Glue the fi xed pivot pin 120 in the channel at the other end of the
bay door as shown. The actuating horn 62 can also be glued in
place at this stage. Note that the linkage holes in the horn must
face the CFRP stiffening strip.
Repeat the procedure with the right-hand cargo bay door 21.
Figs. 72 - 76
The next step is to install the cargo bay doors themselves: turn the
fuselage over, resting on its back, and slip the rear, fi xed hinge pin
120 into the hole in the former. With the L-shaped pin 121 pulled
back, align the door carefully, then slide the hinge pin through the
sleeve and into the hole. It should then be possible to fold the pin
down, so that it is trapped by the magnet. Repeat the procedure
with the second cargo bay door.
Figs. 77 + 78
The servo which opens and closes the cargo bay doors needs to
be installed with the output shaft on the left-hand side, as seen
from the nose of the model. When the bay doors are open, the
servo output arm should be angled down by about 45° as shown.
The doors are actuated by means of two pushrods 118, one of
which is connected to the outer hole in the servo output arm, the
other to the next hole towards the centre.
Mount the swivel connectors 67 in the inner holes of the cargo bay
door horns. Slip the pushrods through the connector barrels, and
tighten the M3 x 3 mm grubscrews 68 to secure them.

15. Installing the propeller and spinner (KIT+RR)
Fit the taper collet 142 and the propeller driver 141 on the motor
shaft. Slide the lock washer 140 above, then slip the spinner
backplate 139 and the propeller 137 on the propeller driver. Fit
the 8 mm I.D. spreader washer 137 and the retaining nut 136, and
tighten the nut lightly, so that you can still adjust the propeller's
position relative to the spinner backplate. Position the propeller,
the backplate and the spinner cap 135 in such a way that the
propeller fi ts neatly through the two cut-outs when the spinner
cap is pushed fully into place. Remove the spinner cap again and
tighten the propeller retaining nut fully. The spinner can now be
replaced, and secured with the M3 x 20 mm retaining screw 134.

16. Installing the tow release servo (KIT+RR)
Place the tow release servo (HiTec HS-225BB # 11 2225) in the
appropriate recess in the fuselage, with the output shaft on the left
as seen from the nose of the model. Fix the servo in place with
hot-melt glue applied to the mounting lugs.
Connect the pre-formed end (Z-bend) of the tow-release pushrod
119 (1.5 x 62 mm steel rod) in the innermost hole of the servo
output arm as shown, then slip the free end of the pushrod through
the tow release mechanism 75, and fi t the output arm on the servo
output shaft, pointing horizontally to the left. Fit the output screw
to retain the servo output arm.

17. Installing the POWER-MULTIlight system in the fuselage
(KIT+RR)
The fi rst step here is to remove the dummy lamps on the rudder
(rear and top), using a sharp balsa knife to cut them off fl ush with
the surface. Hollow out a little foam at these points so that the
LED and its cable fi t inside the rudder. Fix the LEDs in place with
a drop of Zacki, and press the cables into the slots in the rudder.
Run the cable forward through the cable duct, and plug it into
the Multilight control unit. The rear LED is white, and the top one
(beacon) is red. If you wish to install another LED on the underside
of the fuselage, we recommend fi tting it just aft of the cargo bay,
forward of the fl oats support.
