Section 1 – Aileron Servo Installation
Required Parts
• Wing panel (right and left)
Required Tools and Adhesives
• Phillips screwdriver (small)
• Drill bit: 1/16"
• Drill
• 12" Servo Extension (JRPA098)
• 24" Servo Extension (JRPA102)
Step 1
Install the servo hardware (grommets and eyelets)
included with the servo.
Step 2
Plug a 12" and a 24" servo extension onto two of
the servos. Either tie the servo leads together, using
a commercially available connector, or use unwaxed
dental floss to secure the extensions to prevent them
from coming loose during flight.
Step 3
Tie a weight to a piece of string. A wheel collar works
great in this application. Lower the string into the
wing from the aileron servo opening. Let the weight
drop out through the wing root for the servo.
Section 1 – Aileron Servo Installation
7
Step 4
Insert the servo with the 24" extension towards the
tip of the wing. Use the string to pull the servo lead
through the wing. Position the servo so the output
shaft is towards the trailing edge of the wing. Use
a 1/16” drill bit to drill the locations for the servo
screws. Mount the servos using the hardware
provided with the servos.
Step 5
Repeat Steps 3 and 4 for the servo near the root of
the wing panel.
Step 6
Repeat Steps 1 through 5 for the remaining
wing panel.

Section 2 – Aileron Control Horn Installation
Required Parts
• Wing panel (left and right)
• Aileron (left and right)
Required Tools and Adhesives
• Felt-tipped pen • Drill bit: 5/32"
• 8-32 tap • Tap handle
• Square • Ruler
• 30-minute epoxy • Rubbing alcohol
• Drill (drill press preferred)
• 8-32 x 2" Hangar 9
®
control horn screw (4)
(Included in HAN1220 (JR™) or HAN1221 (FUT))
• Hangar 9 control horn A-nut (4) (Included in
HAN1220 (JR™) or HAN1221 (FUT))
Step 1
Tape the aileron to the wing. Make a mark 1/2"
away from the edge of the servo towards the tip
of the wing. Using a square held in alignment (90°)
with the mark and with the trailing edge, mark the
aileron with a pen where the straight edge intersects
the aileron hinge bevel.
Step 2
Measure exactly 3
3
/8" forward from the trailing edge
of the aileron and make another mark using a felttipped pen. The intersection of the line from Step 1
and this line will be the position for the control horn.
Step 3
Repeat Steps 1 and 2 for the second control
horn location.
Step 4
Remove the ailerons from the wing. Use rubbing
alcohol to remove any tape residue.
Step 5
Using a 5/32" drill bit and drill press, carefully drill
through the aileron at the marked position. Be
especially careful when penetrating through the top
surface of the aileron, as it’s easy to split out the
wood and rip the covering. Placing a wooden block
under the aileron and drilling slowly will prevent
these problems. If you choose to use the counter
sink screws included in the Hangar 9® Hardware
Package, counter sink the top of the aileron to allow
the screws to fit flush.
Section 2 – Aileron Control Horn Installation
9
Note: A hardwood block (hard point) is
located below the sheeting; you will be drilling
through this. Make sure to drill the hole
perpendicular to the top of the aileron.
It is highly recommended to use a drill press
to achieve this.
Step 6
Using an 8-32 tap, tap the hole just drilled
in the aileron.
Step 7
Mix a small amount of 30-minute epoxy and lightly
coat the inside of the tapped hole and the 8-32 x 2"
Hangar 9 control horn screw. From the top of the
aileron, screw the 8-32 x 2" into the tapped hole and
securely tighten. Wipe away any excess epoxy with
rubbing alcohol and a paper towel. Screw the A-nut
in place as shown. Allow the epoxy to fully cure.
Step 8
Screw the molded swivel link onto the 8-32 screw
until the distance from the aileron surface to the
top of the link is 1
1
/8".
Step 9
Repeat Steps 1 through 8 for the remaining aileron.

Section 3 – Hinging and Sealing the
Control Surfaces
Required Parts
• Wing panel (right and left)
• Aileron (left and right)
Required Tools and Adhesives
• 30-minute epoxy • Syringe
• Sandpaper (coarse) • Toothpicks
• Robart hingepoints
Properly hinging the control surfaces on giant-scale
models is vitally important! Poorly installed hinges
affect the model’s precision and control response and
can also be dangerous. Each and every hinge needs
to be securely bonded in place in both the flying
surface and the control surface. The hinge pivot
points need to be exactly parallel to each other and
precisely located on the center of the hinge line. We
regularly use Robart Super Hinge Points in all giantscale aircraft. They are easy to install, very strong,
and offer smooth friction-free control. The
Hangar 9
®
Extra 330S control surfaces are predrilled
to use Robart’s Super Hinge Points.
Step 1
Sand each end of the hinge point hinge using
coarse sandpaper. This will improve the bond of
the epoxy to the hinge.
Step 2
Mix 1 ounce of 30-minute epoxy. Using a glue
syringe or toothpick, place a sufficient amount of
30-minute epoxy into one of the hinge pockets in the
aileron leading edge. Install one of the hinge points
until the hinge pin center is flush with the leading
edge of the aileron. Some epoxy should ooze out of
the pocket as the hinge is installed. If not, remove the
hinge and apply more epoxy. After gluing a few
hinges, you’ll get the hang of just how much epoxy is
needed. Wipe away any excess epoxy with rubbing
alcohol. Recheck that the center of the hinge pin is
flush and parallel with the leading edge. Continue
installing hinges in the leading edge of the aileron.
The control surfaces (ailerons) will be installed after
the epoxy is fully cured.
Note: Be sure that the hinge pivot pins are
parallel and flush to the aileron leading edge.
It’s important to frequently mix a fresh batch
of 30-minute epoxy in order to achieve good
glue joint penetration. If you notice the epoxy
becoming thicker, then mix a new batch!
Section 3 – Hinging and Sealing the Control Surfaces
11
Step 3
Allow the epoxy to fully cure for at least 6 hours.
When cured, work each hinge throughout its full
motion several times using your hands. This will
break free any epoxy that may have found its way into
the hinge joint. Move the hinge throughout its full
travel until no resistance is felt. This may take as
many as 40 or 50 times.
Step 4
Mix 1 ounce of 30-minute epoxy. Using a syringe or
toothpick, place a sufficient amount of epoxy in each
of the hinge pockets in one wing panel.
Step 5
Carefully attach the aileron to the wing, making sure
the hinges are inserted in their respective hinge
pockets. Press the aileron and wing together such
that less than a 1/64" hinge line gap exists between
the aileron and wing. The bevels should virtually
touch. Use a paper towel and rubbing alcohol to wipe
away any visible epoxy around the hinges.
Step 6
Double-check the hinge gap and allow the epoxy
to fully cure for at least 6 hours. Now is a good
time to repeat Steps 1 through 5 for the remaining
wing panel and aileron.
12
Section 3 – Hinging and Sealing the Control Surfaces
Step 7
When fully cured, move each control surface
throughout its travel range several times to
break away any epoxy in the hinge. Be sure to
deflect the surface fully.
Section 4 – Sealing the Hinge Gaps
Step 1
Cut a piece of Clear UltraCote (not included) for
sealing the ailerons to approximately 3" x 42". Fold
the UltraCote down the center with the adhesive side
to the outside making a sharp crease at the fold.
Required Parts
• Wing panel (right and left)
• Aileron (left and right)
Required Tools and Adhesives
• Straight edge/ruler • Felt-tipped pen
• Scissors • Hobby knife w/#11 blade
• Clear UltraCote® (HANU964)
• Covering Iron (HAN101)
It’s imperative that the aileron and elevator hinge
lines be sealed airtight to prevent flutter. Sealing the
hinge line has several advantages. A sealed hinge
line gives a greater control response for a given
control deflection. It also offers more precise,
consistent control response and makes trimming
easier. Sealing the aileron and elevator hinge line is
mandatory. Failure to do so may cause control
surface flutter, resulting in a crash.
Section 4 – Sealing the Hinge Gaps
13
Step 2
Using a ruler, measure 1/2" from the folded crease
and mark two places with a felt-tipped pen.
Step 3
Using a sharp #11 blade and a straight edge,
carefully cut through both layers of UltraCote
®
covering at the 1/2" point marked in Step 2.
Step 4
Mark and cut the folded covering to an overall length
of 40". This piece will be inserted and ironed down
into the hinge bevel on the bottom of the aileron.
Step 5
Remove the backing from the UltraCote. Place
the folded crease side into the center of the hinge
line on the bottom of the wing. Using a straight edge
as shown, hold one side of the covering in place
while ironing down the opposite side with a sealing
iron. We recommend setting the iron temperature to
320° for this procedure.
Step 6
Fully deflect the aileron in the up position. Place the
straight edge over the hinge line covering that you
just ironed down in Step 5 with the edge of the
straight edge placed firmly at the bottom of the hinge
line as shown. Iron down this side of the covering,
making sure the aileron is fully deflected.

Section 5 – Aileron Linkage Installation
Required Parts
• Aluminum servo arms (4)
• Control horn ball ends (4)
• 4
1
/2" 4-40 linkage (4)
Required Tools and Adhesives
• Phillips screwdriver (small)
• Threadlock
MatchBox Option: To simplify the installation of
the aileron servo linkages, you may want to use the
JR™ MatchBox™ servo matching/power system
(JRPA900). Four MatchBoxes would be used in this
application—one for each wing panel, one for the
rudder and one for the elevator servo configuration.
The MatchBox allows easy adjustment of the servo’s
center and endpoints, making radio setup a snap.
You can also use a separate battery to run the
Matchbox, reducing the load on the flight battery
powering the receiver.
Step 1
Screw a 4-40 ball link 5 to 6 turns onto each end of
a 4
1
/2" long 4-40 linkage. Adjust the linkage length
until the hole in the ball link aligns with the outer
hole in the servo arm when the aileron is neutral
and the servo arm is centered.
Note: Hangar 9®Titanium Pro-Links feature
right-hand threads on one end and left- hand
threads on the other, allowing for easy,
accurate adjustment without disconnecting
the linkages. Consistently putting the righthand threads toward the servo arms on all
servos will prevent you from getting confused
as to which way to turn the linkage to lengthen
or shorten the link. Hangar 9 also offers a
Pro-Link™ Wrench (HAN3558) to make
adjustments easier.
Step 2
Using the 4-40 screws (don’t substitute a standard
screw) and nuts included in the Hangar 9 package,
attach the ball link to the outer hole in the arm from
the bottom side as shown. The sequence is screw,
tapered standoff, ball link, servo arm and nut. Don’t
forget to use threadlock.
Step 3
Attach the servo horn to the servo using the screw
provided with the servo.
Section 5 – Aileron Linkage Installation
15
Step 4
Attach the linkage to the servo horn on the aileron.
Adjust the link so the aileron is centered at the same
time as the servo.
Step 5
Repeat Steps 1 through 4 for the second servo.
Step 6
Repeat Steps 1 through 5 for the remaining servos in
the opposite wing panel.
