At the transition between the wing centre
section and the fuselage the servo leads
should project by about 5 cm. Naturally it is
also possible to install a single four-pin con-
nector: the positive and negative servo wires
are soldered to common pins, leaving two
pins for the two signal wires.
•
The next step is to install the aileron linkages
in the outboard wing panels: glue the horns
in the ailerons using 5-minute epoxy, exactly
in line with the servo output arms. It is impor-
tant to position the linkage holes exactly over
the aileron hinge pivot axis.
•
The pushrods themselves are assembled
from the pre-formed rods, threaded couplers
and plastic clevises provided; solder the
couplers securely to the pushrods. Alter-
natively 5-minute epoxy can be used, but in
this case the rods must be thoroughly
roughened and degreased beforehand.
•
Once everything is installed and working
correctly, the servo well covers can be fitted:
carefully cut them out and fix them using
clear adhesive tape. Check repeatedly that
the servo well covers do not obstruct the
movement of the servo output arms.
•
The outboard wing panels are plugged into
the centre section using the pre-formed steel
joiner rods. Secure each joint with a strip of
tape before every flight.
The fuselage
•
The wing retainer screw engages in a
threaded sleeve which should now be glued
in the fuselage together with the plywood
spreader disc; these parts are installed in the
central hole, working from the inside. Use 5-
minute epoxy for this, and take care that no
glue runs into the threaded section.
•
The V-tail linkages are installed next: glue
the former to the control 'snakes' as shown,
and glue this assembly in the tail boom.
Slide the snakes aft as far as possible. En-
sure that the former is positioned 'squarely'
in the fuselage. Glue the assembly in the
boom by applying small quantities of 5-
minute epoxy to the joints using a long
screwdriver.
