Align a straight-edge from the outboard side of the servo control
arm to the elevon parallel to the center line. Make a line on the
elevon.
Align the control horn to the line on the elevon in line with the servo
control arm. Use a punch or any pointed tool to mark the position
of the holes in the control horn foot. Drill two holes big enough for
the 2 x 56 self tapping machine screws. Thread the machine
screws through the elevon into the nylon locking pad. Snug the
screws to make a slight impression in the balsa wood. Do not
over tighten!
Screw the threaded clevis onto the control rod so that equal
threads are showing on both sides of the clevis. Hold the elevon
in the neutral position and make a mark where the control rod
matches the top hole in the control arm.
The diameter of the control rod may be reduced with a file or belt
sander to fit better into the control arm. The control arm hole may
be enlarged with a drill or by spinning an X-Acto blade in the hole.
Attach control rods to the servo control arms with a Z-bend. (NOTE:
Z-bend pliers may be purchased from your local hobby dealer to
make this operation easier.) Long nose pliers will also work to
make a Z-bend.
Mechanical centering of the elevon can be achieved by removing
the clevis from the control horn and screwing it in or out.
