1. Open your kit slowly and take care not to dam-
age any parts of the kit. Remove all parts from
their plastic protective covers for inspection.
Before doing any assembly or installation of any
decals it is very important to re-shrink or re-
tighten the already applied covering. Due to the
shipping process, heat and humidity changes
from different climates, the covering may be-
come lose and wrinkle in the sun. If you take the
time to re-tighten the covering, you will be re-
warded with a long lasting beautifully covered
model.
TIGHTENINGAND RE-SHRINKING THE COVERING
2. Using your covering iron with a soft sock, gently
apply pressure and rub in the covering. If any
bubbles occur, your iron may be to hot. Reduce
heat and work slowly.
3. If bubbles persist, use a small pin to punch holes
in the bubble to relieve trapped air and reheat.
4. Use your heat gun with extreme caution. Take
care not to apply too much heat to one area for
long periods of time. This may cause the trim
colors to over shrink and pull away leaving un-
sightly gaps on the color lines. The trim stripes
are especially vulnerable to over shrinking.

13
1. Your model is covered with Ultracote™ covering.
In case of repairs, the colors are:
Orange/Blue Scheme
Orange #877
Sky Blue #875
White #870
Silver #881
Ultracote™ Colors

14
1. Go over all seams and color overlaps with your
sealing iron.
Note: Even if your models covering has no
wrinkles out of the box it is still very
important to go over all seams and overlaps
to make certain they are sealed securely.
This is especially important at the leading
edges of the wings and stabs. We
recommend checking the covering after each
flying session.
CHECKING SEAMS AND COLOR OVERLAPS FOR GOOD SEAL
2. Use your covering iron to ensure all edges,
seams, and color overlaps are securely sealed.
3. This is an optional step but is recommended.
Cut strips of clear covering to fit the hinge
gaps. Use covering iron to seal the clear
covering snugly into the bottom of the
hinge lines as shown for air tight hinge
seals.
IMPORTANT:
It is the responsibility of the purchaser /
operator to check the covering seams and
overlaps for security and a good seal.
Aeroworks is not responsible for failure of
covering seams or overlaps during flight.
Note: If covering continues to lift apply a small
amount of thin CA underneath the covering.
Then using a clean rag apply pressure to secure.
One of the most important tools in your
flight box is a roll of clear tape. This can be
used at the field for fast and easy repairs of
the covering. Then once you have finished
flying the covering can be permanently
repaired.

15
CHECKING HINGES FOR PROPER THROW
2. Evenly heat each hinge along the entire length of
the wing. This will allow the hinge glue to soften
and the hinge to move into it proper position.
Hold the surface at full deflection until the
hinges have cooled down and the glue has re-
hardened.
3. If the elevator hinges are tight follow the
same process as described for the wings.
Note: Once these steps have been completed
the hinges will throw to their full deflect-
tion.
IMPORTANT
1. If control surfaces will not throw to full deflec-
tion it may be necessary using a heat gun to
apply heat to the knuckle of each hinge. This
will allow the hinges to move freely.

16
1. Go over all seams and glue joints with thin CA,
this will ensure your model lasts for many sea-
sons to come.
Note: Even if you can visibly see glue on all glue
joints it is still recommended that the joints be
reglued. Due to changes in humidity during the
life of the aircraft glue joints can separate, it is
always recommended that the glue joints be
checked before each flying session.
CHECKING GLUE JOINTS
2. Use thin CA to reglue any accessible glue joint
as shown below.

17
Aileron Servo Installation
1. The ailerons have been pre-hinged and glued to
the wing panels and are ready for flight. No
other steps are necessary for hinging.
◊ 1 - Wing panel
◊ 1 - Aileron servo
◊ 1 - 1 1/4” Servo Arm
◊ 4 - Servo Mounting Screws (Micro Fastener
Part number STW0209 recommended)
◊ 1 - 6” servo extension
◊ 1 - Aeroworks Safety Clip
WINGASSEMBLY
3. Layout the servo on the wing to test fit the in-
stallation and ensure servo lead is the correct
length.
Note: 165 in. oz. digital, metal geared servos are
recommended. Servo selection can be the
difference between a great flying model and a
model that will crash. Always use brand name
high quality servos.
2. Attach the 6” extension to the servo lead and
secure with Aeroworks Safety Clip. Ensure the
connectors will not come apart from vibration or
light tension.
4. Fasten the pull string from the servo hole to the
male plug of the servo extension.
Safety Clips
Available
from
Aeroworks

18
5. Draw the servo extension through the wing and
pull through the wing root rib.
Note: Taping servo lead to the inside of the wing
panel will help to prevent lead from dropping back
inside of wing panel
during transportation
6. Install servo in servo well with the output arm
toward the leading edge of the wing. Mark and
drill location of servo mounting holes.
7. Install servo with servo mounting screws.
Pushrod / Control Horn Installation
1. Gather the aileron control linkage parts as
shown below.
◊ 1 - 3” pushrod
◊ 2 - 4-40 ball link assemblies
◊ 1 - Brass spacer
◊ 1 - Flat washer
◊ 2 - Lock nuts
◊ 1 - Left control horns
◊ 1 - Right control horns
◊ 6 - Wood screws
◊ 1 - Adjustment wrench-Not Pictured
Wing
LeadingEdge

19
2. Assemble the pushrod and control horn assem-
bly as shown. The ball link goes between the
left and right sides of the control horn sides and
is secured with a nylon lock nut. Start with the
center hole in the control horn. The ball link
may be moved up or down for more or less con-
trol throw. Brass spacer goes between servo arm
and ball link
3. Correct installation of ball link to servo arm
shown below.
Note: Flat washer will prevent ball link from
coming loose from brass ball.
4. Place the control horns over the predrilled
mounting holes.
5. Use a drop of thick CA glue on each screw to
prevent screws from loosening due to vibration
as shown.
Pushrods have both left and right hand threads.
This allows for easier fine adjustments during final
setup. Be sure to thread ball link correctly onto
pushrod. Ball links are self taping and can be used
on either ends of the pushrod. Once ball link has
been threaded only rethread it onto the same direc-
tion threads.

20
6. Securely fasten the control horn to the aileron
with six wood screws.
Note: CA glues have a fast drying time.
Remember to work quickly.
7. Tape the aileron to the wing using masking tape
as shown below. Adjust the length of the push-
rod so that the servo arm is parallel to the aileron
hinge line and the trailing edge of the aileron is
even with the trailing edge of the wing in the
neutral position.
Note: Control horns have been set at a slight offset
to provide full power at full deflection.
9. Use the opposite end of the adjustment wrench
to tighten the pushrod jam nuts against the ball
links. This will prevent the pushrod from turning
in flight.
8. Use the supplied adjustment wrench to adjust the
pushrod as shown below.
