Thank you for choosing the Aeroworks 30cc LC-126ARF-QB. We put great effort into
making this plane the best model you will ever build and fly. We have provided you
with the highest quality kit and performance possible. We wish you great success in the
assembly and flying of your new Aeroworks 30cc LC-126ARF-QB. Please note that
many of the assembly steps and pictures in this manual are for the 1.80-30cc Cessna
195, both the Cessna 195 and LC-126 share all of these assembly processes.
!WARNING!
An R/C aircraft is not a toy! If misused, it can cause serious bodily harm and property
damage. Fly only in open areas, and AMA (Academy of Model Aeronautics) approved
flying sites. Follow all manufacturer instructions included with your plane, radio,
servo’s, batteries and engine.

INTRODUCTION
Your new 30cc LC-126ARF-QB is a scale airplane. The aircraft builds easily, quickly, and
precisely due to its state of the art CAD design, LASER cut technology, and high quality in-
cluded hardware. We hope you enjoy building and flying your 30cc LC-126ARF-QB.
Great care has been taken in both the design and manufacturing of the 30cc LC-126ARF-QB
to allow for the strongest and lightest construction possible. Only the highest quality materi-
als from the covering, paint, wood and hardware have been used in the construction of this
model.
The 30cc LC-126ARF-QB has been individually hand built, covered and painted by trained
and experienced craftsmen with over 25 years of manufacturing experience. Using CAD de-
sign, laser cut technology and jig-built assures accuracy in all stages of production.
The 30cc LC-126ARF-QB is designed for glow and gas engines in the 1.60 glow and 30cc
gas category. The OS 1.60 Satio 1.80 and DLE 30cc engine are shown in the assembly in-
structions. The aircraft was tested with the Satio 1.80 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 advantage of the full capabilities of this aircraft.
IMPORTANT Please read through this manual carefully, before starting the assembly of
your new 30cc LC-126 ARF-QB . Inventory and inspect all parts and hardware for any im-
perfections or damage. Notify Aeroworks immediately if there are missing or damaged
parts. INTENDED USE
This plane should not be regarded as a toy. This is an intermediate to advanced skill level model and
is recommended for pilots who are beyond the trainer-stage.

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 it is recommended
that the cockpit hatch, canopy, and instrument
panel be removed. This will aid in assembling
the model. These items will be reinstalled when
the rest of the model is finished. Use a Phillips
screwdriver to remove the cockpit hatch as
shown below.
Removing Cockpit Hatch and Instrument Panel
2. Using a Phillips screw driver remove the canopy
from the fuselage as shown below.
3. Use a Phillips screw driver to remove the mount-
ing screws holding the instrument panel in place.
4. Lift the instrument panel out of the fuse through
the canopy opening as shown. Be careful not to
damage the instrument panel or the canopy brac-
ing bar. Also take care not to scratch the felt in-
side the fuse.

11
1. 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. DO NOT use a heat gun on the corrugated con-
trol surfaces. Heat applied directly to these sur-
faces will cause the material to deform and bub-
ble.
4. If bubbles persist, use a small pin to punch holes
in the bubble to relieve trapped air and reheat.

12
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 recom-
mend checking the covering after each flying ses-
sion.
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. Use a small trim iron to iron out the wrin-
kles in the hinge lines. It is important to
keep the covering sealed down in this area.
Note: Take care not to apply to much heat
around any plastic or corrugated parts.
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.

Aileron/Flap Servo Installation
1. The ailerons/flaps have been pre-hinged and
glued to the wing panels and are ready for flight.
No other steps are necessary for hinging.
Gather (1) wing panel, (1) aileron servo, (1) Flap
Servo (8) servo mounting screws, (4) Wood
screws for mounting blocks, (2) 1 1/4” servo
arm , (2) safety clip (1) 6” servo extension (1)
18” Servo Extension and (4) Servo Mounting
blocks as shown below for preparation of the
servo installation.
WINGASSEMBLY
2. Using a Phillips screw driver remove the aileron
servo mounting hatch as shown below.
3. Use a C-Clamp to hold the servo mounting
blocks to the servo as shown. Use a block of
wood to elevate the servo mounting hatch as
shown.
4. Use a 1/16” drill bit to drill the mounting holes
for the servo mounting screws as shown.

15
5. A hand drill may also be used to drill through
the blocks as shown below.
6. Install the servo mounting screws as shown.
7. Mark the location of the servo mounting blocks
onto the servo hatch as shown below. Make sure
the servo arm is positioned in the opening as
shown below.
8. Use 5 to 15 minute epoxy to glue the servo
mounting block to the servo hatch. Be careful
not to get any epoxy on the servo case.

16
9. Use a C-Clamp to hold the servo against the
hatch until the epoxy fully cures. Use a piece of
balsa or foam on the bottom of the C-Clamp to
avoid crushing the servo mounting hatch.
10. For added strength install provided wood screws
into the servo mounting blocks as shown below.
This will ensure that the block will be unable to
come loose.
11. Repeat steps for the 3 remaining servos.
13. Layout the servos as shown below. Install the
extensions at this time and double check exten-
sion length.
12. Attach the 6” and 18” extension to the servo
lead and secure with Aeroworks Safety Clip.
Ensure the connectors will not come apart from
vibration or light tension.
Safety Clips

17
15. Draw the servo extension through the wing and
pull through the wing root rib.
16. Taping servo lead to the inside of the wing panel
will help to prevent leads from dropping back
inside of wing panel during transportation.
17. Gather the aileron and flap control linkage parts
as shown below. (1) 3” pushrod aileron, (1) 2.5”
Pushrod flap (4) 4-40 ball link assemblies, (2)
brass spacers, (4) flat washer, (2)control horns,
and (8) wood screws for each wing panel.
14. Fasten the pull string from the servo hole to the
male plug of the servo extension.

18
18. Install the servo hatch back in the wing as
shown. The servo arms will be towards the lead-
ing edge of the wing.
19. Reinstall the 4 mounting screws as shown be-
low. Be careful not to strip the wood the screws
go into.
20. Place the control horns over the predrilled
mounting holes.
21. Use a drop of thick CA glue on each screw to
prevent screws from loosening due to vibration
as shown.
Wing Root

19
22. Securely fasten the control horn to the aileron
with four wood screws.
24. Install pushrod as shown below. The ball links
should be positioned towards the wing tip on
both the servo arm and pushrod.
25. Correct installation of ball link to control horn
shown below.
23. Correct installation of ball link to servo arm
shown below.
Note: Flat washer will prevent ball link from
coming loose from brass ball.
