The prepared tail assembly can now be glued to the fuselage. Caution: in this case
you must not spray activator in the fuselage beforehand, as this would prevent you
adjusting the position of the tailplane.
Note that the front edge of the fin (11) must line up with the trailing edge of the wing.
Connect the elevator pushrod (16) to the centre hole in the elevator horn (18), then
slip the pushrod into the snake outer sleeve (10). Position the horn on the underside
of the elevator, and glue it in place.
The rudder linkage, consisting of parts (17) and (18), is installed in the same manner,
except that the outermost hole in the horn should be used.
The picture shows the servos glued in the fuselage. The pushrods (16) and (17) run
through the swivel pushrod connectors (13); cut them to length using the side-cutters.
Use a 1.5 mm A/F allen key and flat-nose pliers to tighten the grubscrews in the
swivel connectors. Remember to set the rudder and elevator exactly to centre before
tightening the screws.
Important: set the servos to centre from the transmitter (or use a servo tester) before
fitting the output arms on the servo shafts. If possible, fit the output arms at 90° to the
long side of the servo cases.
The picture shows the prepared parts (19) to (23), ready for gluing in the wing (21).
Sand the carbon fibre tube (22) overall, then remove all traces of sanding dust. To
glue the threaded inserts (19) in place, fit the screws (20) in them first, as this allows
you to check that they are exactly vertical and parallel.
Glue the carbon fibre tube (22) in place at the same time as the plastic undercarriage
supports (23). Be sure to use plenty of adhesive when installing the threaded inserts
(19).
Fit the foam support wheels (26) on the undercarriage legs (24), and use mini flat-
nose pliers to bend the ends over to retain the wheels.
The picture shows one undercarriage leg fitted in the support and secured with the
self-tapping screw (25).
Note: if you wish, you can omit the undercarriage components (24) to (30). The
undercarriage installation is of particular interest if you have access to a smooth take-
off strip for take-off and landing. If you are looking for best possible performance, and
only have a grass flying field, the undercarriage is not really necessary. In this case
apply the decal (31) over the wheel recess in the underside of the fuselage.
The picture shows the main undercarriage components (27 to 30). Start by gluing the
wheel support 28 to the underside of the wheel box (27), then complete the assembly
with the wheel axle (29) and the main wheel (30).
Glue the complete main wheel assembly in the fuselage, taking care to avoid glue
running into the wheel bearing.
