INTRODUCTION
IMPORTANT!!!
Two of the most important things you can do to preserve the
radio controlled aircraft hobby are to avoid fl ying near fullscale aircraft and avoid fl ying near or over groups of people.
PROTECT YOUR MODEL, YOURSELF
& OTHERS… FOLLOW THESE
IMPORTANT SAFETY PRECAUTIONS
Thank you for your purchase of HK Arc u s , a
aerobati c Pattern Biplane, perfect for hon ing you r
precisio n flying skills . Features the light and dur abl e
EPO material, the efficie nt moto r and the advanced
propelle r cou ple with the 3S Lipo battery ma ke th is
biplane hi gh po wer to weight ratio for ultra
performa nce a nd vertical climb.
After open ing t he box, you will be greeted by th e sle ek
lines of thi s gor geous aircraft come toget her o n your
work bench . For tunately, all of th e tim e consuming
work has bee n don e for you, the bolt together
assembly a llo ws this plane to be flight read y in le ss
than 15 minu tes .
Before beg inn ing the assembly please rea d thi s
instruct ion t horoughly to gain an unders tan ding of the
sequence o f ste ps and a general awareness of t he
recommen ded a ssembly procedures.
1. Your HK Arcus should not be considered a toy, but rather
sophisticated, working model that functions very much like a
full-size airplane. Because of its performance capabilities, 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. 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
m e m b e r s h i p i n c l u d e s e x p e r i e n c e d p i l o t s .
4. 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 motor 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.
We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fly ability of your finished model depends on how
you build it; therefore, we cannot in any way guarantee the
perfor m a n c e o f y o ur c o mp l et e d m o d el , a n d n o
representations are expressed or implied as to the
performance or safety of your completed model.

transmit ter. P lease refers to your Transmi tte r Manual
for the oper ati on procedures. Make sure al l the c ontrol
sticks are i n neu tral position(Rudder, el eva tor and
ailerons ) and t he throttle in the OFF positi on. Tu rn on
the transm itt er make sure all the trims and the sub t rim s
(For compu ter ized TX) are in neut ral p osition, and then
power on the E SC fo r the control system testing.
!!!Cauti on: To prevent personal i nju ry, do not install
the propel ler o nto the motor shaft in the proc ess t o

2. The m otor and the ESC comes pre-co nne cted,
please mak e sur e the motor rotates in the righ t
directio n. The motor on the Arcus s hou ld rotates
counter cl ock wise from the front view. If inc orr ect
swap any two o f the t hree motor wires.
!!!Caution: To prevent personal injury, do not install
the propeller onto the motor shaft in the process
testing the motor direction.
3. The motor has an optional brake setting, the brake
of the ESC comes with the model has been programmed
off as we recommend the model to be flied with brake
off. However, the brake could be accidently switched on
if the motor battery is connected to the ESC whilst the
throttle stick is set at full. To switch the brake off, Turn
on the transmitter, push the throttle to the highest position,
connect the battery to the ESC, then wait two seconds to
enter the programming mode. The are two series of
four beeps, pull the stick to the lowest position during
the second four beeps.
4. Battery selection and configuration. We recommend
the 11.1V 1P 25C 2200mAh to 2600mAh (180g-240g)
Lipo battery. If using another battery, the battery must be
at least a 11.1V 1P 25C
2200mAh to 2600mAh battery,
your battery should be approximately the same capacity,
weight and can even fit into the Arcus battery hatch.

FLYING THE HK ARCUS
Note: The C.G. (Center of Gravity)is t he lo cation on
the wings, m eas ured back from the most leadi ng ed ge
of the top win gs on b oth sides of the fuselage, wh ere
the model ba lan ces. In addition to the contr ol su rface
throws, th e C.G . has a great effect on the w ay th e
model flie s. If t he C.G. is too far aft (tail heavy), t he
model will b e too r esponsive and diffi cult to control.
If the C.G. is too fa r for ward (nose-heavy), the mo del
will be too st abl e and not responsive enough . Fol low
the instru cti ons to make sure the model is bal anc ed
properly a nd th e C.G. is in the correct locati on.
1. The r ecommended C.G. locatio n for y our model is
( from the mos t lea ding edge of the
top wing as th e pic ture shows whilst with the ba tte ry
pack insta lle d.
2.When bal anc ing your model, support the p lan e on the
relative p oin t at the bottom of the top wing wit h you f ingers
or a commerc ial ly available balancing st and .

Check the C. G. (C enter of Gravity)
Although the Arcus is an extremely plane made
of durable foam, this biplane with four ailerons
configuration make it more responsive but floating
even with the low rate and is therefore not recommended
for beginner pilots. But the plane is easy to fly for
pilots with moderate experience, if you have not
previously flown a pattern or a 3D plane but be familiar
with other conventional plane it is strongly suggested
you learn to fly with that one first.

Always cho ose a w ide-open space for flying y our p lane.
It is ideal fo r you t o fly at a sanctioned flying fi eld . If yo u
are not flyi ng at a n approved site, always avo id fl ying near
houses, tr ees , wires and buildings. You shou ld al so be
careful to a voi d flying in areas where there a re ma ny
people, su ch as b usy parks, schoolyards, o r soc cer fields.
Consult la ws an d ordinances before choos ing a l ocation
to fly your ai rcr aft. After takeoff, ga in some altitude. Climb
to a safe alti tud e and begin to trim the model til l it’s tracks
well throu gh al l aspects of flight, includ ing h igh speed
passes, in ver ted flight, loops, and poin t rol ls.
1. Land the model when you hear the motor pulsing (LVC)
or if you notice a reduction in power. If using a transmitter
with a timer, set the timer so you have enough flight time to
make several landing approaches.
2. Recharge the battery and repair the model as needed.
The model’s three point landing gear allows the model to
land on hard surfaces. Align model directly into the wind
and fly down to the ground. Fly the airplane down to the
ground using 1/4-1/3 throttle to keep enough energy
for proper flare. Before the model touches down, always
fully decrease the throttle to avoid damaging the propeller
or other components. The key to a great landing is to
manage the power and elevator all the way to the ground
and set down lightly on the main landing gear. After a few
flights you will find the model can be set down lightly on
the mains and you can hold the tail wheel off balancing the
model on the mains till it slows and gently settles the tail.
Repairs to t he fo am should be made with foam saf e
adhesive s suc h as hot glue, foam safe CA, and 5 mi n
epoxy. When parts are not repairab le, s ee the Spare Parts
List for ord eri ng by item number. Always check t o mak e
sure all scr ews o n the aircraft are tightene d.
As a precaut ion , an operational ground ran ge te st
should be pe rfo rmed before the first fligh t eac h time
you go out. Pe rfo rming a range test is a good way to
detect pro ble ms that could cause loss of con tro l such
as low batte rie s, defective or damaged rad io
componen ts, o r radio interference. This usually
requires a n ass istant and should be done at th e act ual
flying sit e you w ill be using.
First turn o n the t ransmitter, then install a full y-charged
battery in to th e fuselage. Connect the bat ter y and
install th e hat ch.
Remember, u se ca re not to bump the throttle sti ck,
otherwis e, th e propeller will turn and pos sib ly cause
damage or in jur y.
Note: Plea se re fer to your Transmitter Manu al th at
came with yo ur ra dio control system to perfo rm a
ground ran ge ch eck. If the controls are not wo rki ng
correctl y or if a nything seems wrong, do not f ly th e
model unti l you c orrect the problem. Make ce rta in
all the serv o wir es are securely connected t o the
receiver a nd th e transmitter batteries h ave a g ood
connecti on.
Find a flyin g sit e clear of buildings, trees , pow er lines
and other ob str uctions. Until you know how m uch a rea
will be requ ire d and have mastered flying yo ur pl ane
in confine d spa ces, choose a site which is at le ast t he
size of two to t hre e football fields – a flying fi eld
specific all y for R/C planes is best. Never f ly ne ar
people– es pec ially children who can wand er
unpredic tab ly.
Monitor an d lim it your flight time using a tim er (s uch a
s one on a wrist w atc h or in your transmitter if ava ila ble).
When the bat ter ies are getting low you will us ual ly
notice a per for mance drop before the ESC cut s off
motor powe r, so wh en the plane starts flying sl owe r
you should l and . Often (but not always) powe r can b e
briefly re sto red after the motor cuts off by holding the
throttle s tic k all the way down for a few second s.
To avoid an unex pec ted dead-stick landing on y our f
irst fligh t, se t your timer to a conservative 4 min utes.
When your al arm s ounds you should land right a way.
When you lea rn ho w much flight time you are gett ing
you can adju st yo ur timer accordingly.
Find a suitable flying site
Perform a range check
Monitor your flight time
Take off
Until you have become comfortable with flying your
Arcus , do not fly if the wind speed is greater than
10mph.
One final check before takeoff: always double-check the
flight control response to your inputs from the transmitter
before every flight. Be sure the ailerons, elevator and
rudder respond correctly and that none of the controls
have inadvertently become reversed.
And make sure the spinner and the propeller are firmly
in place before every flight.
Place the model on your “runway” with the nose pointing
into the wind-this will reduce the speed that must be
reached and automatically provide the assist for the
take off, make the takeoff and steering easier. Slowly
advance the throttle, adding rudder correction as needed
to keep the model rolling straight. When the plane becomes
light continue to apply throttle until you are at full-power, all
this will happen in a few seconds. When sufficient liftoff
speed has been reached gradually and slowly apply
up elevator, allowing the model to leave the ground.

Landing
Note: If dur ing a r ough landing, the propell er be come
stuck and ca nno t rotate, the battery and the ESC wi ll
become ver y hot . Immediately move the thro ttl e down
to cease the p owe r input, if you fail to do so, the motor
or the ESC may b e dam aged.
