INTRODUCTION
Your new 150cc Extra 300
ARF-QB is a highly aerobatic airplane. It is capable 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 150cc Extra 300 ARF-QB.
Great care has been taken in both the design and manufacturing of the 150cc Extra 300
ARF QB to allow for the strongest and lightest construction possible. Only the highest qual-
ity materials from the covering, paint, wood and hardware have been used in the construction
of this model.
The 150cc Extra 300 ARF-QB has been individually hand built, covered and painted by
trained and experienced craftsmen with over 25 years of manufacturing experience. Using

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.
TIGHTENING AND 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.
!IMPORTANT!
Go over any and all seams and color overlaps
with your iron to assure good adhesion of the
covering to the wood. This is especially im-
portant at the leading edges of the wings and
stabs.
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 heating and
over shrinking.
Tightening and re-shrinking the covering is now
complete
. However, this is a never ending
process and should be checked after each
flying session.

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

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.
12
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.
13
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.
Gather the following items for installing the aileron
servos:
◊ 1 - Wing panel
◊ 2 - Aileron servos
◊ 2 - 1 1/2” Servo Arms
◊ 8 - Servo Mounting Screws (Micro Fastener
Part number STW0209 recommended)
◊ 1 - 36” servo extension
◊ 1 - 12” Servo Extension
◊ 2 - Aeroworks Safety Clips
Note: (2) 6” extension will also be needed per
wing when connecting aileron servos to re-
ceiver.
WING ASSEMBLY
2. Layout the servos and extensions on the wing to
test fit the installation and ensure servo leads are
the correct length.
Minimum recommended servo:
333 in. oz. / Metal Geared / Digital
3. Attach the 36” extension to the outboard servo
lead and secure with an Aeroworks safety clip.
Ensure the connectors will not come apart from
vibration or light tension.
14
5. Pull the servo lead through the root end of the
wing.
6. Attach the 12” Extension to the inboard servo
lead and secure with an Aeroworks safety
clip. Ensure the connectors will not come
apart from vibration or light tension. Pull the
servo lead out the root of the wing and secure
leads to inside of wing with tape or Velcro.
This will prevent the extensions from slipping
back into the wing.
7. Install servo in servo well with the output shaft
toward the leading edge of the wing. Use a 1/16
bit to drill servo mounting holes.
Note: Servo arms go towards wing tips.
4. Remove the balsa stick with the pull string from
the servo well and tie the pull string to the servo
lead as shown.

Aileron Control Linkage
Installation
1. Gather the aileron and control linkage parts as
shown below.
◊ 2 - 3” pushrod
◊ 4 - 4-40 ball link assemblies
◊ 2 - Brass spacers
◊ 2 - Flat washer
◊ 2 - Left control horns
◊ 2 - Right control horns
◊ 12 - Wood screws for each wing panel
◊ 1 - Adjustment wrench
8. Finished servo installation shown below. 2. Assemble two pushrod and control horn
assemblies 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.
IMPORTANT: The ball link for the root end
control horn goes in the bottom hole of the horn.
The ball link for the tip end
horn goes in the mid-
dle hole of the horn. This gives the correct offset
to eliminate binding and twisting of the aileron.
Note: It will still be necessary to either program or
use a after market type Match Box system to as-
sure your servos will not bind or fight against
each other.
Tip end
Middle hole
Root end
Bottom hole
3. Correct installation of ball link, flat washer and
brass spacer to servo arm shown below.
Note: Flat washer prevents ball link from
coming off brass ball.
16
5. Use thick CA on each screw prior to
installing to lock screws in place.
Note: CA glues have a fast drying time.
Remember to work quickly.
4. Align the control horns over the factory drilled
holes.
Note: Control horns have been set at a slight
offset to allow for maximum torque at full
deflection.
6. Align the left and right sides of the control horns
to the mounting holes and secure using six wood
screws as shown.
7. Install servo arm to pushrod as shown below.
17
9. Finished wing assembly shown below. Repeat
process for remaining wing.
8. Plug the servos into the receiver and turn on.
Ensure servos are centered and the servo arms
are parallel to the aileron hinge line. Adjust
the length of the pushrods so that the aileron is
at the neutral position when the servo arms are
parallel to the aileron hinge line. Ensure all
servos do not fight each other at center or
either end point at full deflection. Take advan-
tage of servo programmers and match boxes
available today to achieve best results. This
will help keep servos from binding and
causing possible aileron flutter.
18
