Step 2
Locate the horizontal stabilizer and elevator assembly and
remove the elevators and hinges. Use a felt-tipped pen or
pencil and ruler to mark the center of the stabilizer at the
trailing edge as shown.
Step 3
Mark the center of the stabilizer saddle at the trailing edge
of the saddle.
Note
: The horizontal stabilizer is positioned all
the way forward in the saddle area to allow
room for the elevator joiner wire. The wire will
be inserted through the saddle area before the
horizontal stabilizer is glued in place.
Step 4
Slide the horizontal stabilizer through the saddle opening
and align the marks you made in the two previous steps.
Once you are satisfied with the alignment, carefully place
a T-pin through the stabilizer and the saddle at the trailing
edge. This will keep the horizontal stabilizer in place
during alignment.
Step 5
Mount the wing to the fuselage and measure the distance
from the wing tip to the tip of the horizontal stabilizers
as shown in the illustration below. Carefully adjust the
horizontal stabilizer until the measurement is equal on
both sides making sure to keep the marks on the stabilizer
and saddle aligned.
