1 INT RODUC TION
Thank you for buying HUBSAN products. The helicopter is designed as an easy to
use, full featured RC helicopter model capable of all forms of rotary flight. Please read
the manual carefully before assembling the model, and follow all precautions and
recommendations within the manual. Be sure to retain the manual for future
reference, routine maintenance, and tuning.
1.1 IMPORTANT NOTES
This RC helicopter is not a toy, it utilizes various high-tech products and technologies
to provide superior performance.
Please read this manual carefully before operating this product. Improper use of this
product can result in serious injury. Be aware of your personal safety, safety of others
and your surrounding environment.
We recommend that you obtain the assistance of an experienced pilot before
attempting to fly our product for the first time.
2 SAF ETY N OTES
2.1 CAUTION
R/C helicopters have parts that move at high speed, thus posing a certain degree of
danger. Pilots are responsible for any actions resulting in damage or injury from the
improper operation of their R/C aircraft models.
Choose a wide open space without obstacles. Do not operate R/C aircraft near
buildings, crowds of people, high voltage cables, or trees to ensure the safety of
yourself, others and your model.
Operate this unit within your ability. Do not fly whilst tired, improper operation may
cause in danger.
2.2 LiPo Battery Recharging
Your helicopter is powered by a Lithium-Polymer (LiPo) battery.
These inputs will result in your model adopting a nose-down right-roll attitude. Note that the top
rotor remains almost horizontal (as a result of the gyroscopic stabilizer arm), while the servos
have pushed the swash plate to tilt the lower rotor right-and-forwards in the intended direction
of travel.
Tip- if you become confused, releasing your helicopter’s controls will bring it to a stop. It will not
lose height, as the Throttle is on a ratchet.
The effect of simultaneous control inputs will, with practice, result in elegant slip-free turns
which demonstrate the sophisticated controls of your 4 channel RC helicopter.
6.7 Flying Outdoors
The final challenge is to fly your helicopter outdoors under open skies!
Remember, your helicopter is designed for indoor operation, where low-speed
precision-control is paramount. When flying in the great outdoors - even though you may think
it’s absolute flat calm - you will notice that your helicopter is susceptible to almost
imperceptible air currents. This presents an interesting challenge for the experienced pilot, but
could spell disaster if attempted too soon. So, take your time and practice the Flying Lessons
described in this manual until you have acquired proficiency in the Advanced Maneuvers.
Make sure it really is a flat calm day outside. And remember that outdoor flight is a whole new
learning experience.
Flying your radio-controlled helicopter outdoors really is great fun. Just remember its design
limitations and be prepared to make the professional pilot’s decision to cancel your plans and
you helicopter will live to fly another day.
Never recharge your battery whilst it is inserted in your model. It can catch fire leading
to the total destruction of the item.

4. Notice that the cyclic joystick is spring-loaded, you must maintain a forwards pressure on the
cyclic joystick otherwise it will return to its neutral position and your helicopter will stop moving.
Tip-if you become confused, releasing your helicopter's controls will bring it to stop. it will not
lose height as the throttle is on a ratchet.
5. Stop you helicopter, turn it around (use rudder), and bring it back.
6. Choose a landing site. Fly your helicopter to a position that is precisely over your chosen
landing site and set your helicopter down in a smooth and precise landing.
7. Repeat this flying lesson until you become S-M-O-O-T-H-L-Y proficient and precise.
3.5 Advanced Maneuvering
In this flying lesson you will combine cyclic joystick Pitch and Roll inputs with collective Rudder
and Throttle inputs to give more precise control to your helicopter maneuvers.
You've probably already tried combining Rudder and forward Pitch inputs. This combination
allows you to turn your helicopter, but it won’t look right. The helicopter will remain upright. It's
like watching a bicycle that's not leaning into the turn, because air has very little grip, your
helicopter will actually skid through its turn.
The solution is to make the helicopter lean-"Roll"-so that rotors help to counteract the tendency
to skid (or 'side slip').To do this, you must learn to synchronise your use of mixed Pitch and Roll
on the cyclic joystick, with mixed Rudder and Throttle on the collective joystick
1. Begin a hover at shoulder height.
2. Push the cyclic stick Forwards to gather sufficient airspeed.
3. Begin your turn by pushing the cyclic joystick to the right (setting up the Roll) while
maintaining forward pressure.
4. As your model begins to respond to the Roll, push the collective Rudder joystick to the right
to initiate the turn.
LiPo batteries differ from conventional batteries in that their chemical contents are
encased in a relatively insubstantial foil packaging. This has the advantage of
significantly reducing their weight, but does make them more susceptible to
damage if roughly or inappropriately handled. As with all batteries, there is a risk
of fire or explosion if safety practices are ignored:
Charge and store LiPo batteries in a location where a battery fire or
explosion (including smoke hazard) will not endanger life or property
Keep LiPo batteries away from children and animals
Consider how you would deal with a LiPo battery fire/explosion as part of your
normal home Fire Safety & Evacuation Planning
Never charge a LiPo pack that has ballooned or swelled due to
over-/under-charging or from a crash
Never charge a LiPo battery pack that has been punctured or damaged in a
crash (After a crash, inspect the battery pack for the sign of damage. Discard
in accordance with your country’s recycling laws.).
Do not charge LiPo batteries near flammable materials or liquids
Ensure that charging leads are connected correctly. Reverse polarity charging
can lead to battery damage or a fire or explosion
Never charge a LiPo battery in a moving vehicle
Only charge your LiPo battery using the supplied “balanced” charger
Have a suitable(electrical type) fire extinguisher near the charging area OR a
large bucket of dry sand. Do not try to extinguish electrical (LiPo) battery fires
with water
Reduce risks from fire/explosion by storing and charging LiPo batteries inside
a suitable container: a LiPo Sack or metal/ceramic container is advised
Monitor recharging LiPo batteries for signs of overheating
5. Don't forget to be ready to catch the helicopter's loss of lift. As you servos are creating a
battery power drain, you will need to increase the collective Throttle while maintaining the
Rudder input Exiting the Turn maneuver
6. At the end of the turn, begin to SUMULTANEOUSLY ease off the cyclic Roll, collective
Rudder and the additional Throttle inputs. You should practice until you can simultaneously
use all of the joystick inputs in smooth, synchronized
movements. This will take a lot of practice!
13
Never over charge a LiPo battery
Never leave a LiPo battery unattended during recharging
Protect your LiPo battery from accidental damage during storage and
transportation. (Do not put battery packs in pockets or bags where they can
short circuit or can come into contact with sharp or metallic objects.)
If your LiPo battery is subjected to a shock (such as a helicopter crash) you
should place it in a metal container and observe for signs of swelling or
heating for at least 30 minutes
Do not attempt to disassemble or modify or repair a LiPo battery

2.3 PREVENT MOISTURE
R/C models are composed of many precision electrical components.
It is critical to keep the model and associated equipment away from condensation and
other contaminants. Exposure to water or moisture may cause the model to
malfunction resulting in loss of responsiveness, or a crash.
2.4 PROPER OPERATION
For the safety purpose, please only use hubsan’s spare parts for replacement.
2.5 ALWAYS BE AWARE OF THE ROTATING BLADES
When in operation, the main and tail rotor blades will be spinning at high speed. The
blades are capable of inflicting serious body injury and damage to the environment.
Be cautious of your actions and careful to keep your body and loose clothing away
from the blades. Never take your eyes off the model or leave it unattended while it is
turned on. Once landed, immediately turn off the model and transmitter.
2.6 AVOID FLYING ALONE
Beginners should avoid flying alone whilst learning flight skills. It is advised that an
experienced pilot be on hand for guidance.
It is recommended to practice with a computer-based flight simulator.
6.4 Basic Maneuvering
In this Flying Lesson you will use the cyclic joystick and the Rudder to maneuver
your helicopter.
1.Keeping a safe 1 to 2 meters from your model, S-M-O-O-T-H-L-Y advance the
collective Throttle joystick until your helicopter reaches approximately shoulder
height.
2.S-L-O-W-L-Y apply collective Rudder control to point the nose of your helicopter in
the direction you wish to fly.

Tip: The helicopter will find the rudder
central automatically in 3 seconds after

3 SAF ETY C HECK BEFOR E FLY ING
CAREFULLY INSPECT BEFORE REAL FLIGHT
• Before operation, please check the batteries of the transmitter and receiver are
charged enough for the flight.
• Before turning on the transmitter, please check that the throttle stick is in the
minimum position.
• Check for any missing or loose screws and nuts. Carefully check main rotor blades
and rotor holders. Broken or premature failure of parts will result in a dangerous
situation.
• Check all the ball links to avoid excess play and replace as needed. Failure to do so
will result in poor flight stability.
• Check the battery and power plug are securely fastened. Vibration and violent flight
may cause the plug to loosen resulting in loss of control.
• When turning on the unit, please follow the power on/off procedure: for Power ON-
please turn on the transmitter first, and then turn on the receiver. For Power OFFplease turn off the receiver first and then turn off the transmitter. Improper procedure
may cause loss of control of the helicopter.

3.Once you have turned your helicopter, place your right thumb over the tip of the
cyclic joystick and S-L-O-W-L-Y press forwards.
OFF OFF
MODE 2 MODE 1
The lower rotor will tilt forward. The helicopter’s nose will pitch down. Your helicopter
will begin to move forward.
Tip- Be ready to slightly increase your Throttle power, as the helicopter is likely to
lose a little height during maneuvering. Also remember that the swash plate on the
helicopter links all of your cyclic controls; so don't be surprised if your helicopter
moves slightly to the left/right as well as forwards. As you gain experience, you will
stop thinking in terms of Left/Right or Forwards/Backwards and start to automatically
synchronize cyclic joystick corrections, just like flying a full size helicopter.

6.3 Hovering and Cyclic Trim
Because your helicopter’s rotors create a ‘downdraft’ any
attempt to hover at too low an altitude (height) is more
difficult than hovering a little higher. This difficulty is
because the downdraft from your rotors is bounced back off
the ground, resulting in turbulent air around the
helicopter-this is referred to as ‘Ground Effect’. For this
reason, we recommend that you begin your hovering
practices at about 1 meter off the ground.
1. Keeping a safe 1 to 2 meters from your model, S-M-O-O-T-H-L-Y advance the
collective Throttle joystick until your helicopter reaches approximately waist height.

2.If the helicopter has a tendency to rapidly move in any direction, either:
a.LAND IMMEDIATELY, by S-M-O-O-T-H-L-Y reducing the throttle power. Then
adjust the trim sliders to compensate. Repeat the sequence from Step1, above.
b.GENTLY apply cyclic joystick correction in the opposite direction to the
helicopter’s aberrant movement. Once you’ve established the amount of required
control correction, land your helicopter. Adjust the trim sliders equivalent to the
amount of the applied joystick compensation. Repeat this sequence, beginning at
Step1, above.
3.GENTLY and S-L-O-W-L-Y push forward/pull back on the collective Throttle to
maintain an even height without ‘bouncing’ the helicopter up and down.
Tip: for more sensitive control-and improved ability to mix Throttle and Rudder
inputs-try placing your left thumb on the tip of the collective joystick.

IMPORTANT: KEEP YOUR CONTROL INPUTS VERY S-L-O-W & GENTLE
1. Set the collective Throttle joystick and trim slider to its lowest setting. All other
trim sliders should be at their mid positions.
2. After completing the ‘Power-On (Failsafe) Procedure’, place your model on a

4.2Battery Mounting
Notice: >Do not mix old and new batteries
>Do not mix different types of batteries
>Do not charge non-rechargeable battery.
Tip: The helicopter will find the
rudder central automatically in
3 seconds after the helicopter
landing on the ground.
3. Keeping a safe 1 to 2 metres away from your model, always ready to switch off
the Throttle, S-L-O-W-L-Y advance the collective Throttle joystick until you can see
that the model’s landing skids are just trying to lift but are not yet hovering.
4. Observe how your helicopter behaves.
5. Most likely, your model will begin to Yaw (rotate) or Roll (topple to one side). It
may even show signs of an inclination to Pitch (Rock forwards or backwards) onto
its nose or tail.
6. Adjust the appropriate trim slider(s) to counteract any observed movement(s).
7. Once the trim sliders have balanced your helicopter, it is time to test the Rudder
response. Move the collective joystick S-L-O-W-L-Y to the Left/Right and verify that
your model is responding as shown in the ‘Effects of Controls’ illustration.
8. You will probably find you need to re-adjust the slider trim to get an equal
response from Left/Right Rudder inputs.

If your helicopter’s control response do not correspond to the behaviour described in
‘Effects of Controls’, check that your Servo Reverse switches are set correctly.
Note: we have not yet used the cyclic joystick controls (other than their trim sliders),
as these will tilt the helicopter, which may cause the lower rotors to touch the
ground. This would result in wear or damage.

6. Fl ight Train ing
Your RC helicopter is an easy-to-fly model but, you don’t become an expert pilot
without taking time to learn the basics. As the saying goes:
In other words, if you don’t want your first few flights to end in a pile of mangled
wreckage-requiring expensive repairs to your new model – take the time to follow this
brief Flight Training Program. After all, learning to fly your helicopter is all part of the
enjoyment!
6.1 Power-On (Failsafe) Procedure
Your RC helicopter’s 4-in-1 Gyro Receiver is fitted with a Power-On failsafe.
This is designed to ensure that the helicopter’s motor will not start unless it detects a
suitable radio-control signal when the LiPo battery is connected. The correct Start-Up
sequence is as follows:
OFF
Power-On Transmitter
Put the helicopter on a horizontal ground
OFF ON CHG
Switch-On the helicopter
There is a short high tone when the signal is established
