We , as the kit manufacturer have providedyou with a top quality,
thoroughly tested kit and instructions, but ultimately the quality and
flyability of your finished model depends on how you build it. Therefore,
we cannot in any way guarantee the performance of your completed model,
and no represent ations are expressed or implied as to the performance or
safety of your c o
mpleted model.
This airplane is not a toy, but rather a sophisticated working model that
functions very much like a full size airplane. Because of its perfor
mance
capabilities, the plane, if not assembled and operated correctly could possibly
cause injury to yourself or spectators and damage property.
Keep items that could become entangled aw ay from the rotating propeller,
including loose clothing and toolsetc. Be especially sure to keep your
hands, face and other parts of your body away from the propeller blades.
As the user of this product you are solely and wholly responsible for oper-
ating it in a manner that does not endanger yourself and others or result
in damage to the property of others.
Y ou must assemble the model according to the instructions. Do not alter or
modify the model in anyway, as doing so may result in an unsafe or
unflyable mode l. In a few cases the instructions may differ slightly from the
photos due to updates. In these instances the written instructions
should be considered as correct.
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 flight. If you are not a member of a club,
your local hobby shop should have information about clubs in your area
whose membership includes experienced pilots.
This model has been flown and flight tested to beyond normal limits, but if
the plane is used for extreme and high stress flying such as racing , or if
a motor larger than the one in the recommended range is used, the
modeler is respon sible for taking steps to reinforce the high stress points
and / or substituting hardware more suitable for the increased stresses.

7. Install the tailplane tothe fin using the screw provided.

9. Connect the pushrod to the servo arm and fix the servo arm to the
rudder servo with a screw (do not connect the pushrod to the horn at this point)
10. Connect the aileron pushrods to the servo arms and fix the servo arms
with a screw, (do not connect the pushrods to the horns at this point)
8. Connect the pushrod to the
rudder servo arm.
12. Put the metal joiners through
the
corresponding hole
of the
fuselage and con-
nect the servo wires of the
ailerons and flaps.

11. Insert the metal wing joiners to the
main wing.

13 . Connect the main wings to thefuselage using the plastic clips.
Ensure that hear and feel a sound “click” when fitting the main wings to the fuselage,
this tells you that the wings have located properly.
With the transmitter turned on and the LiPo flight battery connected to the
ESC
( and installed in the battery compartment) it’s now possible to conn-
ect the pushrods to the rudder and elevator control surfaces and to ‘center’
the surfaces accordingly.
Firstly, be sure to center the elevator and rudder ( aileron ) trim levers. Press
the trim button till it has a short and big drop sound, ( a long and big
drop sound
means you reach the end of the trim in one side).
With the trim levers centered, carefully spread open each ‘clevis’ ( the white
color plastic part installed on the threaded end of the metal pushrod ) so you
can insert the pin in the OUTERMOSThole on each control horn. It may be
helpful to insert a flat blade screwdriver (not included) into the clevis then
carefully ‘twist’it until it disengages the pin from the hole in the clevis. Also,
it is not necessary to ‘snap’the clevis back together until the centering adj-
ustments are complete.
Centering the Control Surfaces
14. Plug in the battery then secure
the canopy.

NOTE:You should always rotate the clevis until the pin is perpendicular with
the control horn to ensure the pin is not under any excessive load/ pressure
when inserted in the hole and during operation. In some cases it may not be
possible to ‘exactly’center the surface mechanically while properly aligning the
pin. In these cases be sure the pin is properly aligned then adjust the position
of the trim lever slightly as needed.Also, it will likely be necessary to make
After connecting the clevises to the control horns view the vertical tail and rud-
der from directly above.The rudder should be ‘ in line ’with the vertical tail
when it’s properly ‘centered’. However, if the rudder is angled off to the right or
left you can adjust the length/position of the pushrod/clevis so the surface
is centered ‘mechanically’ while the trim lever on the transmitter is centered.
If the rudder is angled off to the left carefully remove the clevis from the control
horn and screw it ‘in’(clockwise) one half to one full turn then insert the pin back
into the outermost hole in the control horn. Or, if the rudder is angled off to the
right carefully remove the clevis from the control horn and screw it ‘out’(coun-
ter-clockwise) one half to one full turn then insert the pin back into the outer-
most hole in the control horn.
View the vertical tail and rudder from directly above again and continue adju-
sting the length/position of the pushrod/ clevis until the rudder is centered ap-
propriately.

further adjustments to the position of the trim lever during flight as most surf-
aces do not end up in exactly the centered position when an airplane is trim-
med pr operly for actual flight (but ‘centered’is still the best starting point).
Follow the same steps outlined for centering the rudder to center the elev-
ator (and aileron) as well.
Also, we strongly recommend installing the included ‘clevis keepers’to provide
added security for the clevises.Typically you can carefully slide the keeper s
over the clevises when they are not connected to the control horn.Then, after
connecting the clevis to the control horn and ‘ snapping ’the clevis together
you can slide the keepers into a position that does not allow them to ‘bind’ag-
ainst the control horn during movement of the surface.
Center of Gravity
56 5 mm

The ideal C of G position is 56mm behind the leading edge measured
at where the wing meets the fuselage (you can safely be + or -
5mm either side of this measurement).The C of Ghas a GREAT
effect on the way the model flies.If the C of Gis too far aft ( tail
heavy ), the model will be too responsive and difficult to control. If
the C of Gis too far forward (nose-heavy), the model will be too
stable and not re-sponsive enough. Inorder to obtain the correct
C of G as specified, add weight to the fuselage or move the battery
position. Check the C of G.before you fly.
Battery Warnings
IMPORTANT NOTE: Lithium Polymer LiPo) batteries are significantly more vola-
tile than alkaline, NiCd or NiMH batteries which are also used in RC applications.
All instruc tions and warnings must be followed exactly to prevent property
damage and/ or personal injury as mishandling of LiPo batteries can result in
fire.
By handling, charging or using the included LiPo battery you assume all risks assoc-
iated with LiPo batteries. If you do not agree with these conditions, please return
your complete product in new, unused condition to the place of purchase immediately.
You must read the following safety instructions and warnings before handling,
charg ing or using the LiPo battery.
• You must charge the LiPo battery in a safe area away from flammable materials.
• Never charge the LiPo battery unattended at any time. When charging the bat-
tery you should always monitor the charging process and react immediately to
any potential problems that may occur.
• After flying / discharging the battery you must allow it to cool to ambient /
room temperature before recharging. Also, it is NOT necessary or recommended
to disch arge the battery ‘completely’ before charging ( LiPo batteries have no
‘memory’ and it’s safe to charge partially discharged batteries when using an
appropriate charger that is set correctly).
9

• To charge the battery you must use only use the included Charger or a suitable
compatible LiPo battery charger. Failure to do so may result in a fire causing
property damage and/ or personal injury. DO NOT use a NiCd or NiMH charger to
charge Li-Po batteries.
• If at any time during the charge or discharge process the battery begins to ball-
oon or swell, discontinue charging or discharging immediately. Quickly and safely
disconnect the battery then place it in a safe , open area away from flammable
materials to observe it for at least 15 minutes. Continuing to charge or disch-
arge a battery that has begun to balloon or swell can result in a fire. A battery
that has ballooned or swollen even a small amount must be removed
from service completely and not used anymore. Dispose of as per
regulations.
• Store the battery partially charged (approximately 50% charged/3.85V per cell),
at room temperature (approximately 68–77° Fahrenheit [F] ) and in a dry area for
best results.
• When transporting or temporarily storing the battery, the temperature range
should be from approximately 40–100°F. Do not store the battery or model in a hot
car or direct sunlight whenever possible. If stored in a hot garage or car the battery
can be damaged or even catch fire.
• Do not over discharge the LiPo flight battery. Discharging the LiPo flight battery
to a voltage that is too low can cause damage to the battery resulting in reduced
power, flight duration or failure of the battery entirely. If this happens usually
you will not be able to recharge the battery, do not try forcing a charge into it
as this could cause the battery to swell and catch fire.
• LiPo cells should not be discharged below 3.0V each under load. In the case of
the 2-Cell/ 2S 7.4V LiPo battery used to power the plane you will not want to
allow the battery to fall below 6.0V during flight.
The included ESC features a ‘soft’ low voltage cutoff ( LVC ) that smoothly
reduces power to the motor (regardless of the power level you have set with the
throttle stick) to let you know the voltage of the battery is close to the 6.0V
minimum.
10

However, even before this reduction in power , if you find that more than the
typical amount of throttle/ power is required to cruise or climb you should land the
model and
disconnect the battery immediately to prevent over-discharge.
And while it is possible to continue flying the model after the soft LVC occurs,
t
his is NOT recommended. Continued discharging can result in reaching the 5.0V ‘
hard’ LVC which may cause permanent damage to the LiPo battery resulting in
reduced power and flight duration during subsequent fights ( or failure of the ba-
ttery entirely which is not covered under warranty).
Also, it is not recommended that you fly to the soft LVC every time you fly. Inst-
ead you should be aware of the power level of the battery / airplane throughout
the flight, and if at any time the airplane begins to require more throttle/ power
than typical to maintain cruise or climb you should land the airplane and disconnect
the LiPo battery immediately . Constantly discharging the battery to the soft LVC
can still cause permanent damage to the battery so it’s best to use a timer or
stop -watch to time the duration of your flights and to stop flying at a reasonable
time before the soft LVC is reached.
IMPORTANT NOTE: DO NOT LEAVE THE LIPO BATTERY CONNECTED TO
THE ESC UNLESS YOU ARE READY TO FLY. IF THE BATTERY IS LEFT CON-
NECTED TO THE ESC WHEN IT IS NOT IN USE THE LIPO BATTERY WILL
BE OVER-DISCHARGED BY THE SMALL AMOUNT OF CURRENT THE ESC
CONSUMES.
It can sometimes take a few hours or even up to a few days to over- discharge the
battery this way but doing so will likely cause permanent damage to or failure of
the battery entirely (which is not covered under warranty).
IMPORTANT NOTE: DO NOT STORE THE LIPO FLIGHT BATTERY FULLY CHARGED.
For improved safety and longevity of the LiPo battery it’s best to store it only partially
charged for any length of time. Storing the LiPo battery at approximately 50% charged
(which is approximately 3.85V per cell) is typically best, however it will take some
careful management of the charge time and the use of a voltmeter to achieve
this voltage.
11

If you have the equipment and skills to achieve the 50% charge level for storage it
is recommended. If not, simply be sure to not store the battery fully charged whe-
never possible. In fact ,as long as the battery will be stored at approximately room
temperature and for no more than a few weeks before the next use, it may be best
to store the battery in the discharged state after the last flight (as long as the bat-
tery was not over-discharged on the last flight).
Mode 1 and Mode 2
Depending on which area you are in, you will either use a Mode1 or Mode
2 transmitter. The difference between the two modes is that the throttle
and Elevator stick are transposed. Mode 2 transmitters have the throttle
control on the left stick and the Elevator controls on the right stick. Mode
1 is in the opposite way.
Transmitter Insturction
PLEASE NOTE: The plane is designed to be flown outdoors only.
Flying Conditions
It’s typically best to fly on days that are calm with no wind, especially when learning
how to fly. We strongly suggest flying only in calm conditions until you’re familiar with
the controls and handling of the model. Even light winds can make it much more di-
fficult to learn to fly, and in some cases can even carry the model beyond your line
of sight.

Low Battery Voltage/Power Indication
When the AA battery voltage / power drops to a level that’s too low for safe co-
ntinued
operation , the red color LED indicator will begin flashing. DO NOT use
the tr
ansmitter or fly when the red LED indicator is flashing and immediately insta-
ll new AA
batteries before using the transmitter or flying.
Control / Servo Reversing
The transmitter features control/ servo reversing functionality for the aileron, ele-
vator, throttle and rudder channels. The control / servo directions were set correctly
at the factory for the plane , however , in case the controls are operating in
the
wrong direction , or you use the electronics in other models later on, simply change
the position of ‘Servo Reverse’switch for the channel(s) as needed. Thoroughly
check that the controls are operating in the correct sense BEFORE you fly.
Delta / Elevon Mixing
Located to the right of the ‘Servo Reverse’ switches is a switch that activates / de-
activates the optional-use ‘Delta / Elevon’ mixing. No such mixing is used for this
model so please be sure this switch is in the OFF / lower position ( failure to do
so will result in improper control and the inability to fly the plane ). However, if
using this transmitter with ‘flying wing’ , delta or other airplanes that ‘combine
(mix)’ the elevator and aileron (often known as ‘elevon’) controls you can move the
switch to the ON/upper position.

To bind the receiver
1. Move the throttle stick to the bottom.
2. Turn on the transmitter.
3. Connect the battery to the receiver.
4. Press the bind button of the receiver. (the LED of the receiver will flash quickly)
5. When the LED stops flashing and stays on the bind is successful.
Cautions
Pls make sure the throttle joystick is at the bottom position when you
bind the receiver and before you connect the battery in the model. Please
remove the propeller before binding the receiver as the motor might
inadvertently start and cause injury.
Check The Control Surface and Channel Condition
Before trying to fly the airplane, please carefully check to make sure the
transmitter and the servos work normally. CAUTION: Make sure that you
turn on the transmitter first and only then connect the bat tery plug. If
you want to turn off the transmitter you must ensure that the battery
in the model is disconnected first.

Know Your Frequency
Based on the size and weight of the plane it’s typically considered to be a ‘park flyer’
class model. As a result it’s best to fly the plane at a local park, schoolyard, flying
field or other area that’s large enough and free of people and obstructions. We rec-
ommend an area the size of at least one football/ soccer field, however, even larger
areas are better suited and preferred especially when learning how to fly. DO NOT
fly in parking lots, crowded neighborhood areas or in areas that are not free
o
f people and obstructions.
We also suggest flying over grass as it’s
a much more forgiving surface that
causes less damage in the unfortunate
event of a crash. Short grass is better
for landings as grass that is too
long can cause the airpla ne to nose
over or flip and be damaged.
Fly in a spacious area without
obstacles, or near power lines
or roads or near crowds of
people or spectators.
15

Also, if you are a first-time or low-time pilot we highly recommend allowing
a more experienced pilot to test fly and properly trim the model before
attempting your first flight. A proven flyable and properly trimmed model is
significantly easier and more enjoyable to fly! Please contact your local
hobby shop and/or flying club to find a more experienced pilot near you.
After you’ve properly trimmed the airplane in calm conditions and become fam-
iliar with its handling capabilities you’ll be able to fly in light winds, or depending
on your
experience and comfort level, in winds up to 5–7 mph.
DO NOT fly on days when significant moisture, such as rain or snow, is present.

Know Your Frequency
Flight Checklist
CAUTION: The transmitter used to control your plane transmits signals on
one of several frequencies that are available. To find out your frequency (or
“channel”), look on the transmitter, If your “channel” happens to be the same as
another model that is being flown nearby (even within a few miles), one or both
models will crash. Know your frequency and be aware of the frequency of
other models that are flying nearby, especially if you are flying at a radio control
flying site. All flying sites have some sort of frequency control system to avoid
this kind of interference , so learn how to
use their frequency control system.
Never turn on your transmitter until you are certain that you will be the only one
operating on your frequency.
PLEASE NOTE: This checklist is NOT intended to replace the content included
in this instruction manual. Although it can be used as a quick start guide,
we strongly suggest reading through this manual completely before proc-
eeding.
• Always turn the transmitter on first
• Ensure the throttle control stick is in the bottomposition before plugging in
the battery.
• Hand launch the model with a firm, level throw over a grass field.
• Land the model ideally on a short grass field.
• Unplug the LiPo flight battery from the ESC when you have finished flying.
• Always turn the transmitter off last
17
Perform a Range Check
As a precaution, an operational ground range test should be performed before the
first flight each time out. performing a range test is a good way to detect problems that
could cause loss of control such as low batteries defective or damaged radio
components or radio interference. This usually requires an assistant and should be
done at the actual flying site you will be using.

First turn on the transmitter. Then, install the fully charged battery into the fuselage
and hold it in place with the hook-and-loop strap. Connect the battery and install
the canopy.
Remember, use care not to “knock” the throttle stick , if you do "knock" the
stick the motor will start and the propeller will most likely cause damage or
injury.
With the antenna on the transmitter collapsed (not extended ), begin walking
away from the model operating the controls in a predictable pattern (for example: Up,
then down elevator. Right, then left aileron. Right, then left rudder). While moving
the control surfaces, also vary motor rpm.
Have your assistant alert you if the controls fail to respond or if they move suddenly
or erratically. You should be able to maintain control up to a distance of approxi-
mately100’ [30m].
If the controls respond erratically or if anything else seems wrong, make certain
all the servo wires are securely connected to the receiver and that the transmitter
and receiver batteries are fully charged. If you cannot find a mechanical problem
with the model , it is slightly possible that there is radio interference in the
area. One option would be to try another range check at an alternate flying site.
After the range check, fully extend the antenna.
Monitor and limit your flight time using a timer such as the one on your wrist watch.
When the batteries are getting low you will usually notice a performance drop
before the ESC cuts off the motor power, when you notice the plane flying slower
you should land. Often (but not always!), power can be briefly restored after the
motor cuts off by holding the throttle stick all the way down for a few seconds.
To avoid an unexpected dead-stick landing on your first flight set your timer to a co-
ns ervative 4 minutes.When the alarm sounds you should land your model.
When you learn how much flight time you are getting you can adjust your timer
accordingly. Always be conservative so the motor won’t quit unexpectedly
and you will have enough battery to land with power still available if required..
18

Take Off
Take off (Hand launch)
Until you have become comfortable with flying your plane, do not
fly if the wind speed that is greater than 10 mph [ 16 kilometers /
hr].
One final check before takeoff : always double - check the flight control
response to your inputs from the transmitter before every flight.
Be certain the ailerons , elevator and rudder respond correctly and that none
of the controls have inadvertently become reversed.
Don’ t forget to fully extend the transmitter antenna.
Fly the model over a field of ideally short grass and one that has no obstructions.
Ideally have a helper hand launch the model for you. Have them hold the model
under the wing somewhere close to the C of G position, point it into wind and
hold the model just above shoulder height. The pilot should then call out that he
is starting the motor, he should then smoothly open the power up to full
throttle, the launch person should then launch the model with a firm, level
throw making sure that the wings are also level, DO NOT launch the model
upwards as it may stall and crash. Fly the model level with the ground until
sufficient flying speed has been attained and only then ease it into a gentle
climb.
Keep flying straight into wind until at least 50/75ft, only then should you attempt
a gentle turn away from the take off line. Keep climbing a bit more until you are
around 150ft, then throttle back to somewhere between half and three
quarters throttle so that the model stops climbing and then get used to some
gentle turns after first trimming the model (see further on).
Based on the size and weight of the plane it’s typically considered to be a ‘park flyer’
class model. As a result it’s best to fly the plane at a local park, schoolyard, flying
field or other area that’s large enough and free of people and obstructions. We rec-
ommend an area the size of at least one football/ soccer field, however, even larger
areas are better suited and preferred especially when learning how to fly. DO NOT
fly in parking lots, crowded neighborhood areas or in areas that are not free
o
f people and obstructions.
We also suggest flying over grass as it’s
a much more forgiving surface that
causes less damage in the unfortunate
event of a crash. Short grass is better
for takeoffs and landings as grass
that is too long can cause the airpla-
ne to nose-over /flip and be damaged.
An ideal flying area allows for takeoffs
and landings on a smoother surface
(such as asphalt) and flying over grass.
19

One thing to remember is that, when the plane is flying away from you, moving
the aileron stick to the right will make the plane bank to your right.
However, when the model is flying toward you, moving the aileron stick to the right
will make the plane move to your left. Of course, the plane is still responding the
same way,it’s just that your orientation has reversed. This must be kept in mi-
nd while learning to fly (and is also a good reason to take flight lessons from an
ex perienced pilot!).
To establish a turn gently apply some aileron in the direction you want the model to
bank, once it is at the required angle of bank almost centralise the ailerons, leave
just a small amount in the direction of the turn, a small amount of up elevator will be
required to maintain the correct attitude and to stop a spiral dive developing..To
stop the turn move the aileron stick in the opposite direction, centralise the stick
when the wings are level and remove any up elevator you may still be holding
in.
Once you get the plane into the air and have climbed to a comfortable altitude,
the first “order of business” will be to “trim” the model for straight - and - level
flight. The model flies best at approximately 3/4-throttle. Adjust the trims on the tran-
smitter to make minor control surface adjustments as necessary until the plane will fly
straight and without climbing or descending without any stick in puts at all. If
necessary ask your helper to adjust the trims for you whilst you are flying. A well
trimmed model is much easier to fly than a model that is out of trim, take your time to
get this exercise correct.
