13) Using a modeling knife, cut out the push-
rod exits at the locations marked.
o
14) Insert the elevator pushrod assembly,
threaded wires first, through the servo compart-
ment and out the elevator pushrod exits in the
back of the fuselage.
If you have trouble guiding the threaded
wires out the exit holes, drop a length of
thread through each exit slot and into the servo
compartment. Tie the thread to the ends of the
threaded wire and slowly pull the thread. The
thread will lead the pushrod wires out the exit
holes.
o
15) Thread one nylon clevis onto each
threaded wire. For security they should be
threaded no less than 5/16” onto the wires. Snap
the clevises onto the elevator control horns. See
photo # 42 below.

o
16) Locate a long servo arm and using wire
cutters, remove all but one of the arms. Cut down
the remaining arm to 3/8” long. Install the L-bend
in the pushrod wire into the outer hole in the servo
arm. Secure the wire in place using one nylon
snap keeper.
o
17) Using a couple of pieces of masking
tape, hold the elevator halves in neutral. With the
elevator halves and elevator servo in neutral, in-
stall the servo arm onto the servo. The arm should
be positioned perpendicular to the fuselage sides
and point towards the middle of the fuselage. You
can thread the nylon clevises in further or back
them out to achieve the correct length.
o
18) When satisfied with the alignment, install
the servo arm set screw and remove the masking
tape from the elevator halves. See photo # 43

PARTS REQUIRED
AILERON LINKAGE
o
{2} Nylon Clevises w/2mm I.D. Hole
o
{2} 2mm x 138mm Threaded Rod w/L-Bend
o
{2} Nylon Snap Keepers
o
{2} Nylon Adjustable Control Horns
INSTALLING THE AILERON LINKAGE
o
1) Thread one nylon adjustable control horn
onto each aileron torque rod. Thread them on
until they are 7/8” above the top surface of the
wing. See figure # 16 below.
Figure # 16
o
2) Thread one nylon clevis at least 5/16” onto
each of the two 2mm x 138mm threaded rods
with L-bends.
o
3) With the aileron servo centered, install one
dual takeoff servo arm onto the servo. The arm
should be installed so it is parallel with the trailing
edge of the wing.
o
4) Use a couple of pieces of masking tape,
taped between the ailerons and the trailing edge
of the wing, to hold the two ailerons in neutral.
o
5) Snap the clevises onto the adjustable con-
trol horns. With the servo arm and ailerons cen-
tered, push the L-bends up through the outer holes
in the servo arm. Adjust the length of the wires
by turning the nylon clevises in or out until the
correct length is achieved. Hold the wires in place
using two nylon snap keepers. See photo # 44
at top right.
