INTRODUCTION
Your new 100cc-120cc Ultimate 20-300 ARF-QB is a highly aerobatic airplane. It is ca-
pable of both precision and 3-D maneuvers. The aircraft builds easily, quickly, and precisely
due to its state of the art CAD design, LASER cut technology, and high quality included
hardware. We hope you enjoy building and flying your 100cc-120cc Ultimate 20-300
ARF-QB.
Great care has been taken in both the design and manufacturing of the 100cc-120cc Ulti-
mate 20-300 ARF QB to allow for the strongest and lightest construction possible. Only
the highest quality materials from the covering, paint, wood and hardware have been used in
the construction of this model.
The 100cc-120cc Ultimate 20-300 ARF-QB has been individually hand built, covered and
painted by trained and experienced craftsmen with over 25 years of manufacturing experi-
ence. Using CAD design, laser cut technology and jig-built assures accuracy in all stages of
production.
The 100cc-120cc Ultimate 20-300 ARF-QB is designed for gas engines in the 100cc-
120cc category. The DA-120cc engine is shown in the assembly instructions. The aircraft
was tested with the DA-120cc and has outstanding performance. The final choice of engine
is left up to the builder. A computer radio is recommended to allow the pilot to take advan-
tage of the full capabilities of this aerobatic aircraft.

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.

14
1. Your model is covered with Ultracote™ covering.
In case of repairs, the colors are:
Red/Yellow/Black Scheme
Black #874
Silver #881
True Red #866
Bright Yellow #872
Ultracote™ Colors
Yellow/Silver/Blue Scheme
Pearl Blue #845
Silver #881
Cub Yellow #884
White #870

15
1. Go over all seams and color overlaps with your
sealing iron.
Note: Even if your models covering has no wrin-
kles 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
SEALING HINGE GAPS
2. Use covering iron to ensure all edges, seams,
and color overlaps are securely sealed.
3. Sealing hinge gaps. This is an optional step
but is recommended.
Cut strips of the supplied 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.
Note: The clear covering does have a transparent
protective backing. This must be removed
prior to applying heat and to the surface.
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.

16
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.

17
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.

18
1. Leave the canopy bolted to the airframe at all
times unless working on the inside of the fuse.
Due to high humidity levels during the building
and shipping process the canopy may warp when
not bolted to the airframe.
CANOPY/FRONT HATCH WARP PREVENTION
2. The front hatch should also be bolted to the air-
frame whenever possible.

19
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. Clear
Covering is supplied for sealing the hinge gaps if
desired. However, due to the precisely aligned
and minimal hinge gap this step is optional.
◊ 1 - Wing panel
◊ 1 - Aileron servo
◊ 1 - 1 1/4” Servo Arm
◊ 4 - Servo Mounting Screws (Micro Fastener
Part number STW0209 recommended)
◊ 1 - 12” servo extension
◊ 1 - Aeroworks Safety Clip
WINGASSEMBLY
2. Attach the 12” servo extension to the servo wire
and secure using an Aeroworks Safety Clip.
Minimum recommended servo:
181 in. oz. / Metal Geared / Digital
3. Remove the balsa stick with the pull string from
the servo well and tie the pull string to the servo
lead as shown.
4. Pull the servo lead through the root end of the
wing.

20
5. Install servo in servo well with the output shaft
toward the leading edge of the wing.
Aileron Control Linkage Installation
1. Gather the aileron control linkage parts as shown
below.
◊ 4 - 4-40 x 3” Pushrods-With carbon reinforce-
ment sleeves
◊ 8 - 4-40 Ball Link Assemblies
◊ 4 - Flat Washers
◊ 4 - Brass Spacers
◊ 4 - Left Side Control Horns
◊ 4 - Right Side Control Horns
◊ 24 - Wood Screws
◊ 1 - Adjustment Wrench
3. Correct installation of ball link, flat washer and
brass spacer to servo arm shown below.
2. Assemble pushrod and control horn
assembly 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.
Improperly installed servo linkages can cause ser-
vos to strip and ailerons to flutter. Aileron flutter
can and will destroy your model instantly!
Note: Flat washer prevents ball link from
coming off brass ball.
