NOTE:
You
should
always
rotate
the
clevis
until
the
pin
is
perpendicular
with
the
control
horn
to
ensure
the
pin
is
not
under
any
excessive
load/pressure
when
inserted
in
the
hole
and
during
operation.
In
some
cases
it
may
not
be
possible
to
‘exactly’
center
the
surface
mechanically
while
properly
aligning
the
pin.
In
these
cases
be
sure
the
pin
is
properly
aligned
then
adjust
the
position
of
the
trim
lever
(or
sub
‐
trim)
slightly
as
needed.
Also,
it
will
likely
be
necessary
to
make
further
adjustments
to
the
position
of
the
trim
lever
during
flight
as
most
surfaces
do
not
end
up
in
exactly
the
centered
position
when
an
airplane
is
trimmed
properly
for
actual
flight
(but
‘centered’
is
still
the
best
starting
point).
If
the
elevator
is
angled
upward
carefully
remove
the
clevis
from
the
control
horn
and
screw
it
‘in’
(clockwise)
one
half
to
one
full
turn
then
insert
the
pin
back
into
the
outermost
hole
in
the
control
horn.
Or,
if
the
elevator
is
angled
downward
carefully
remove
the
clevis
from
the
control
horn
and
screw
it
‘out’
(counter
‐
clockwise)
one
half
to
one
full
turn
then
insert
the
pin
back
into
the
outermost
hole
in
the
control
horn.
View
the
horizontal
tail
and
elevator
from
the
side
and
continue
adjusting
the
length/position
of
the
pushrod/clevis
until
the
rudder
is
properly
centered.
IMPORTANT
NOTE:
If
they
are
not
already
installed
we
strongly
recommend
installing
the
included
flexible
clear
tubing
‘clevis
keepers’
to
provide
added
security
for
the
clevises.
Typically
you
can
slide
the
keeper
over
the
clevis
when
it’s
not
connected
to
the
control
horn.
Then,
after
connecting
the
clevis
to
the
control
horn
and
‘snapping’
the
clevis
together
you
can
slide
the
keeper
into
a
position
that
does
not
allow
it
to
‘bind’
against
the
control
horn
during
movement
of
the
surface.
