INTRODUCTION
Congratulations and thank you for purchasing the Tower
Hobbies Kaos .60 ARF. Those familiar with the original Kaos
design dating back to the early ‘70s (or earlier!) will have
nostalgic memories while enjoying a new flying experience.
Newer pilots unfamiliar with the Kaos’ history will enjoy a
good-flying model just the same! With its Pattern pedigree
the Kaos is a smooth, easy flyer more than capable of
maneuvers with grace and precision!
For the latest technical updates or manual corrections
to the Kaos .60 ARF visit the Tower Hobbies web site at
towerhobbies.com and visit the page for the Kaos .60. If
there is new technical information or changes to this model
a “tech notice” box will appear on the page.

SAFETY PRECAUTIONS
Protect Your Model, Yourself & Others…
Follow These Important Safety Precautions
1. Your Kaos should not be considered a toy, but rather a
sophisticated, working model that functions very much like
a full-size airplane. Because of its performance capabilities,
the Sequence, if not assembled and operated correctly,
could possibly cause injury to yourself or spectators and
damage to property.
2. You must assemble the model according to the
instructions. Do not alter or modify the model, as doing so
may result in an unsafe or unflyable model. In a few cases
the instructions may differ slightly from the photos. In those
instances the written instructions should be considered as
correct.
3. You must take time to build straight, true and strong.
4. You must use an R/C radio system that is in good condition,
a correctly sized engine, and other components as specified
in this instruction manual. All components must be correctly
installed so that the model operates correctly on the ground
and in the air. You must check the operation of the model
and all components before every flight.
5. If you are not an experienced pilot or have not flown
this type of model before, we recommend that you get
the assistance of an experienced pilot in your R/C club
for your first flights. If you’re not a member of a club, your
local hobby shop has information about clubs in your area
whose membership includes experienced pilots.
6. While this kit has been flight tested to exceed normal
use, if the plane will be used for extremely high stress
flying, such as racing, or if an engine larger than one in the
recommended range is used, the modeler is responsible
for taking steps to reinforce the high stress points and/or
substituting hardware more suitable for the increased stress.
2
7. WARNING: The cowl included in this kit is made of
fiberglass, the fibers of which may cause eye, skin and
respiratory tract irritation. Never blow into the cowl to remove
fiberglass dust, as the dust will blow back into your eyes.
Always wear safety goggles, a particle mask and rubber
gloves when grinding, drilling and sanding fiberglass parts.
Vacuum the parts and the work area thoroughly after working
with fiberglass parts.
We, as the kit manufacturer, provide you with a top quality, thoroughly tested kit and instructions, but ultimately
the quality and yability of your nished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to
the performance or safety of your completed model.
ADDITIONAL ITEMS REQUIRED
Glow Engine
The Kaos is suited for a .60 2-stroke or .91 4-stroke. The
O.S. Max .65AX (OSMG0558) is illustrated in this manual.
If side-mounting the engine as shown, the short muffler
extension will also be required (OSMG2582).
OTHER ACCESSORIES IF USING A GLOW ENGINE
❍ 1/4" [6.4mm] R/C foam rubber (HCAQ1000)
❍ Great Planes Dead Center Hole Locator
(GPMR8130)
❍ 4mm tap and drill set (GPMR8113)
❍ Suitable propeller as specified by the engine
manufacturer
Brushless Electric Motor
The Kaos flies superbly with a 50-55-500 kV RimFire .80
(GPMG4740), 14"–15" propellers and a 6S LiPo in the
4000 mAh range.
ELECTRONIC SPEED CONTROL
Any 75A ESC for brushless motors is suitable, but the
Castle Creations Edge 75 (CSEM0101) is recommended
because it has a heat sink and can be mounted to the
bottom of the motor mount box inside the cowl. Other ESCs
possibly may not fit in the cowl, but could be mounted in
the fuselage if adequate airflow is provided. A 6" servo
extension (TACM2092) will also be required to extend the
signal lead from the ESC to the receiver.
3S BATTERIES (2 required)
❍ Flight Power 3S 4350mAh 30C (FPWP3433)
❍ Flight Power 3S 4000mAh 25C (FPWP2403)
❍ Flight Power 3S 3800mAh 30C (FPWP3383)
❍ Using two 3S batteries also requires a Series
connector (GPMM3143)
OTHER ACCESSORIES IF ELECTRIC POWERED
❍ Double-sided adhesive-back Velcro is used to help
secure the battery (GPMQ4480)
❍ 3/16" shrink tubing (DUBM2187) is required after
soldering the 4mm bullet connectors (included with
the RimFire motor) to the ESC
❍ A male “T” style battery connector is also required
to connect the ESC to the battery (HCAM4010)
❍ (4) #4 x 3/8" screws (for Castle Creations Edge ESC
mounting)
SUITABLE PROPELLERS FOR RIMFIRE .80
❍ APC 14 x 10E (APCQ1409)
❍ APC 15 x 7E (APCQ1830)
❍ APC 15 x 8E (APCQ4013)
Refer to page 19 for additional guidance on propeller
selection.
IMPORTANT: Before connecting multiple battery packs with
adapter plugs, refer to the Battery Precautions on page 19.
LiPo BATTERY CHARGER
To charge a 6S 4000mAh LiPo recommended for the Kaos
at the minimum charge rate of 1C, a charger capable of at
least 100 watts output is required (6S x 4.2V/cell = 25.2 V x
4A = 100W). The Triton2 EQ (GPMM3156) is rated to 120W
DC and 100W AC so it is a suitable for charger. A dual-output
charger of at least 50W per output would also be suitable
if using two 3S batteries in series.
Radio / Servos
A minimum 4-channels is required to fly the Kaos. The Tactic
TTX650 is recommended because of its versatility, computer
programming and multiple model memory.
❍ Tactic TTX650 6-channel programmable radio
(TACJ2650)
❍ Tactic TR625 6-chanel receiver (TACJ0625)
❍ On-off receiver switch (TACM2000)
BATTERIES
You may use a 6S battery, or two 3S batteries connected in
series. This configuration depends on your charger capabilities
and what batteries you may already have available.
6S BATTERIES
❍ Flight Power 6S 4350mAh 30C (FPWP3436)
❍ Flight Power 6S 3800mAh 30C (FPWP3386)
❍ Flight Power 6S 3800mAh 70C (FPWP7386)
❍ Flight Power 6S 4400mAh 70C (FPWP7446)
A 2S, 1100 mAh LiFe pack (HCAM6416) was used to power
the receiver and servos. If using a receiver and servos other
than those suggested, make sure they are compatible with
the higher voltage of a LiFe battery, or use a different receiver
battery. The Triton2 EQ also has LiFe charge capabilities.
Tactic TSX25 mini digital high-speed 2 ball bearing servos
(TACM0225) are illustrated in the instruction manual. Three or
4 servos will be required depending on whether you power
your Kaos with an electric motor or glow engine. Standard-
3
size servos may also be used, but the servo cutouts will
have to be enlarged.
If mixing the aileron servos through the radio electronically:
❍ (4) 6" [150 mm] servo extensions (TACM2092) are
required for the aileron servos.
If connecting the servos with a Y-harness:
❍ (2) 6" [150 mm] servo extensions (TACM2092)
and a Y-harness (FTM4130) are required for the
aileron servos.
❍ A covering iron with a cover sock may be required
for tightening and re bonding the covering to the
model that may have loosened between the time
the plane was manufactured and the time the model
st
was removed from the box. The 21
Century iron is
preferred because of its long cord, contoured shoe
and precisely adjustable temperature range:
❍ Coverite 21
st
Century Sealing Iron (COVR2700)
❍ Coverite 21st Century Cover Sock (COVR2702)
KIT INSPECTION
ADHESIVES, HARDWARE
& OTHER ACCESSORIES
Other than common hobby tools, here is a list of the rest
of the items required:
❍ If using an electric motor, 30-minute epoxy is
recommended for gluing together the motor mount
box (GMR6043)
❍ Threadlocker thread locking cement (GPMR6060)
❍ Thin CA (GPMR6001)
❍ Medium CA (GPMR6007)
❍ CA applicator tips (HCAR3780)
❍ A Robart Super Stand II (ROBP1402) is also helpful
for working on your Kaos .60.

PREPARATION
1. Use a covering iron set to about 300°F with a covering
❏
sock to go over the model where necessary to shrink the
covering and remove any wrinkles and to bond the covering
to wood underneath. If you will be using a glow engine, pay
special attention to the edges of the covering around the
firewall to make sure it is thoroughly sealed down so fuel
won’t get in.
NOTE: This covering material requires less heat than
you may be used to – too much heat may cause seams
and edges to draw away from each other causing wavy,
uneven edges or exposed balsa.
3. Give a generous tug on all control surfaces to check the
❏
hinges. Add thin CA where necessary to any loose hinges.
Residual CA or any CA “fog” can be removed with a paper
towel dampened with CA debonder.
ASSEMBLE THE WING
2. If powering your Kaos with a glow engine, apply a film
❏
of epoxy or CA to seams around the firewall.
1. Attach a 6" [150mm] servo extension to each
❏
aileron servo and secure with the included 1-1/2" [40mm]
shrink tubing.
5
Enlarge the aileron servo
mount for standard servos.
Cut Out
2. If necessary, enlarge the servo cutouts to fit your servos.
❏
4. Using care not to drill all the way through the ailerons,
❏
drill 1/16" [1.6mm] holes for the aileron horn mounting
screws, then connect the aileron servo to the aileron with
the hardware shown.
5. Temporarily remove the screws and horns from the
❏
ailerons. Add a few drops of thin CA into the holes to harden
them, allow the CA to fully harden, then re mount the horns
with the screws.
6. Mount the 3" [75mm] wheels to the main landing gear
❏
wire with the collars and a drop of threadlocker on the set
screws.
3. Drill 1/16" [1.6mm] holes for the servo screws and
❏
mount the servos.
7. Using the landing gear straps as a guide, drill 3/32"
❏
[2.4mm] holes into the landing gear rails.
8. Using a No. 1 Phillips screwdriver, mount the main
❏
landing gear to the wing with the straps and M3x10 screws.
6
9. Glue the plastic alignment dowels into the end of
❏
each wing.
FUSELAGE
Mount the Tail
3. Insert another long peg up through the horizontal and
❏
vertical stab, but do not glue it in.
4. Key the assembly into the fuselage with the threaded
❏
rods protruding down through the bottom of the fuselage.
1. Glue a short and long alignment peg into the bottom
❏
of the vertical stabilizer – do not glue the long alignment
peg into the back of the vertical stab.
2. Fit the vertical stab to the horizontal stab, keying in
❏
the peg.
5. Use the included finger socket wrench to tighten the
❏
assembly to the fuselage with an M3 flat washer and M3
locking nut on each rod. Do not over tighten – just enough
to tighten up the gap between the bottom of the stab and
the fuselage.

bottom of the fuselage where shown.
❏
to lightly wet the threads of the screws with threadlocker.
1. If installing an electric motor, cut the rest of the way
2. Assemble the nose gear assembly as shown – be certain
3. Cut the nose wheel pushrod guide tube to a length
❏
of 14-1/2" [370mm], then insert it up through the fuselage
where shown – it may be necessary to trim the bottom of
the fuel tank plate block to accommodate the tube.
4. Make a 17-1/2" [445mm] non-threaded pushrod by
❏
cutting the threaded end off the 20" [510mm] pushrod.
Make an “L” bend in one end of the rod about 1/4" [5mm]
from the end.
