5. Product Description
The ready-to-y quadrocopter has 4 separate motors that drive one propeller each. Concurrent acceleration of all
propellers permits the quadrocopter to lift off of the ground and hover stably in the air at the corresponding propeller
speeds.
For stabilisation in ight, the quadrocopter has elaborate gyro electronics able to recognise uncontrolled movements
of the model and balance them out without delay. For the ight in a specic direction, the electronics in the model
recognise the control impulses of the transmitter and change the speeds of the individual motors accordingly. The
quadrocopter then tilts in the desired direction and the lift thus acts as drive as well. The quadrocopter ies in the
respective direction.
Two propellers on the model turn clockwise and two turn counter-clockwise. By targeted speed change of the two
propeller groups against each other (right-ward rotating propellers turn a little faster and left-ward rotating propellers
turn a little slower or vice versa), it is possible that the quadrocopter can turn (yaw) while maintaining ight height
and position.
To better recognise alignment of the model in ight, the two front propellers are made of blue plastic, and the two rear
propellers of orange plastic. Additionally, the two front motors have blue LEDs and the two rear ones have red LEDs.
A central electronics PCB in the middle of the quadrocopter contains all components that are required for stabilising
and steering of the quadrocopter. The 2.4 GHz remote control system included in the delivery allows sensitive steer-
ing of the model.
Beginners have the option of operating the transmitter in Beginner mode. The control reactions of the model are then
clearly reduced (dual rate function). The quadrocopter reacts much more agilely in Sport and in Expert mode. On
demand, the quadrocopter can even y ips.
For operation of the transmitter, 2 AA/mignon batteries (e.g. Conrad item no.: 652506, order 2x) are required.

6. Safety Notes
In case of damage caused by non-compliance with these operating instructions, the warranty/guar-
antee will expire. We do not assume any liability for consequential damage!
We do not assume any liability for property damage or personal injury caused by improper use or
non-compliance with the safety instructions! In such cases the warranty/guarantee is voided.
Normal wear and tear during operation (e.g. worn-out motor-shaft bearings) are excluded from the
guarantee and warrantee, the same is the case for accidental damage (e.g. broken booms or propel-
lers).
Dear customer, these safety instructions are not only for the protection of the product but also for your own
safety and that of other people. Therefore, read this chapter very carefully before taking the product into
operation!
a) General
Caution, important note!
Operating the model may cause damage to property and/or individuals. Therefore, make sure that you are
sufciently insured when using the model, e.g. by taking out private liability insurance.
If you already have private liability insurance, verify whether or not operation of the model is covered by your
insurance before commissioning your model.
Observe: In some countries you are required to have insurance for all model aircraft!
• For safety and licensing (CE) reasons, unauthorised conversion and/or modications to the product are not permit-
ted.
• This product is not a toy and not suitable for children under 14 years of age.
• The product must not become damp or wet.
• If you do not have sufcient knowledge as to how to deal with remote-controlled models, please seek the advice of
an experienced model maker or a model making club.
• Do not leave the packaging material lying around carelessly as it can become a dangerous toy for children.
• Should questions arise that are not answered by the operating manual, contact us (for contact information, see
chapter 1) or another expert.
The operation and handling of remote controlled quadrocopters must be learned! If you have never steered such a
model, start especially carefully and get used to the reactions of the model to the remote control commands rst. Be
patient!

7
b) Before Commissioning
• Always rst switch on the transmitter and then connect the ight battery to the quadrocopter. This is the only way for
an attunement function to take place between transmitter and receiver, so that your model will react reliably to the
control commands of your transmitter.
• Check the functional reliability of your model and of the remote control system. Watch out for any visible damage
such as defective plug connections or damaged cables. All moving parts on the model must run smoothly but must
not have any tolerance in the bearing.
• The ight battery required for operation must be charged before operation. Ensure that the batteries in the transmit-
ter have a sufcient remaining capacity (check with a battery tester). If the batteries are empty, always replace the
complete set, never individual cells only.
c) During Operation
• Do not take any risks when operating the product! Your own safety and that of your environment depends completely
on your responsible use of the model.
• Improper operation may cause serious injury and property damage! Therefore make sure to keep a sufciently safe
distance from persons, animals or objects during operation. Never try to grab the ying model with your hand!
• Fly your model only if your ability to respond is unrestricted. The inuence of tiredness, alcohol or medication can
cause incorrect responses.
• Motors, motor regulator and ight battery can heat during operation. For this reason, wait for 5 to 10 minutes before
recharging or replacing the ight battery or taking off again with a second, already-charged ight battery.
• Never switch off the remote control (transmitter) while the model is in use. After landing, always disconnect the ight
battery from the quadrocopter before switching off the remote control.
• Never switch off the remote control while the quadrocopter is still in operation.
• Never expose your model or the remote control to direct sunlight or excessive heat for an extended period of time.

7. Battery and Rechargeable Battery Notes
Although use of batteries and rechargeable batteries in everyday life is a matter of course today, there are
many dangers and problems. Ensure that you observe the following general information and safety informa-
tion when handling batteries and rechargeable batteries.
• Keep batteries/rechargeable batteries out of the reach of children.
• Do not leave any batteries/rechargeable batteries lying around openly. There is a risk of batteries being swallowed
by children or pets. If swallowed, consult a doctor immediately!
• Batteries/rechargeable batteries must never be short-circuited, disassembled or thrown into re. There is a danger
of explosion!
• Leaking or damaged batteries/rechargeable batteries can cause chemical burns to skin. Wear suitable protective
gloves when handling them.
• Do not recharge normal batteries. There is a risk of re and explosion! Only charge rechargeable batteries (1.2 V)
intended for this purpose. Use suitable battery chargers. Batteries (1.5 V) are intended for one-time use only and
must be disposed of properly when discharged.
• Always observe the correct polarity when inserting batteries or connecting the charger (observe plus/+ and minus/-).
Incorrect polarity will damage not only the transmitter but also the plane model and the batteries. There is a danger
of re and explosion.
• Always replace the whole set of batteries. Do not mix full batteries with half-full ones. Always use batteries/recharge-
able batteries of the same type and manufacturer.
• Never mix batteries and rechargeable batteries! Therefore, only use batteries for the remote control transmitter.
• If the device is not used for an extended period of time (e.g. storage), remove the inserted batteries from the remote
control to avoid damage from leaking batteries.
Attention!
After the ight, disconnect the ight battery from the quadrocopter. Do not leave the rechargeable ight bat-
tery connected to the quadrocopter if the model is not used (e.g. during transport or storage). Otherwise, the
ight battery may be fully discharged and is thus destroyed/unusable!
• Never charge the enclosed ight battery immediately after use. Always let the ight battery to cool down until it has
reached room or ambient temperature again.
• Only charge intact and undamaged ight batteries. If the outer isolation of the rechargeable battery is damaged or
the battery is deformed or bloated, it must not be charged. There is acute danger of re or explosion!
• Never damage the ight battery covering, do not cut the foil cover, do not probe the rechargeable battery with sharp
objects. There is a risk of re and explosion!
• Remove the ight battery from the model for recharging. Never recharge the ight rechargeable battery unattended.
• Disconnect the ight battery from the charging cable when it is charged completely.

9. Setting up the Transmitter
In the further course of these instructions, gures in the text always refer to the adjacent gure or the gures
within the section. References to other gures are indicated with the corresponding gure number.
a) Inserting the Batteries
The power supply of the transmitter requires 2 AA/mignon batteries (e.g. Conrad Item No. 652506, please order 2x).
Important:
Use batteries only (1.5 V/cell) instead of rechargeable batteries (1.2 V/cell) for transmitter power supply.
Proceed as follows to insert the batteries:
Loosen the attachment screw (1) of the battery compart-
ment lid (2) at the back of the transmitter with a suitable
screwdriver.
Push the latching lever (3) of the battery compartment lid
down slightly and fold open the battery compartment lid.
Insert two type AA/mignon batteries with correct polarity
(observe plus/+ and minus/-) according to the specica-
tions at the bottom of the battery compartment (4). The
spiral-shaped spring contact (5) always must be con-
nected to the minus pole of the battery.
Replace the battery compartment lid in the transmitter
housing and let the latching lever latch.
Then tighten the attachment screw again.
Figure 2

b) Switching on the Transmitter
Move the control stick for the pitch and yaw functions
(also see gure 1, item 8) to the bottom position right
at your body.
Slide the on/off switch (also see gure 1, item 7) from the
left position "OFF" to the right position "ON".
The transmitter emits two signal sounds and the LED
display (also see gure 1, item 2) starts to ash.
Slide the control stick (8) for the pitch and yaw functions
all the way up and then all the way down again.
The transmitter emits one signal sound each in the two
end positions and the LED display is now lit permanently.
Then switch off the transmitter again with the on-off
switch.

10. Commissioning of the Quadrocopter
a) Charging the Flight Battery
Caution, important!
Even though this would easily be possible when operating the model later, never charge the ight battery
when installed for reasons of safety. Always remove the ight battery from the model for recharging! Place
the ight battery on a re-proof underground when charging and do not charge the battery unsupervised.
The ight battery is charged with the enclosed USB charging cable. For this, the charging cable is connected to a USB
socket of a computer/notebook or to a conventional USB plug-in charger.
Charging:
Connect the ight battery (1) with the connector protect-
ed against polarity reversal of the USB charging cable
(2). Work with the required care and do not apply any
unnecessary force. The red charge indicator LED (3) in
the USB plug is lit.
Once the USB plug of the charger (4) is connected to
a USB socket of a computer/notebook or a USB plug-
in charger, charging commences automatically. The
charge indicator LED in the USB plug goes out.
The red charge indicator LED in the USB plug lights up
again when charging is completed and the rechargeable
battery is fully charged.
Disconnect the rechargeable battery from the USB
charging cable at once after charging and pull the USB
plug of the charging cable from the computer/notebook
or from the plug-in charger.
For photo-technical reasons, the USB charg-
ing cable is illustrated in the wound-up state
in gure 4. Before rst use, the cable retainer
should be opened and the cable unwound.
Figure 4

13
Practical advice:
To check the charge control light in the USB plug, briey disconnect the rechargeable battery from the charge cable
before it is fully charged. In this case, the red LED in the USB plug must light up. If you connect the rechargeable
battery again, the LED must go out.
Attention!
Do not connect the USB cable to a USB hub without a separate mains adapter (e.g. a keyboard USB port,
etc.), because these will not provide sufcient current for charging.
The operating system does not recognize any new hardware after connection of the charging cable, be-
cause the USB port is only used for power supply. Please observe that the USB ports of your computer/
notebook are usually only active when the computer/notebook is switched on.
Therefore, we recommend to only connect the charging cable to a computer/notebook that is switched on.
Alternatively, you can use a suitable USB plug-in mains unit.
b) Checking the Drive
Before commissioning your quadrocopter, you need to check the drive. Only when all four propellers run smoothly
and perfectly round can the model y with the lowest energy consumption. For this reason, you should check the drive
propeller function briey before each ight.
For this, turn every single propeller carefully with your nger and check concentricity and smooth operation.
Observe the rotating directions of the different propel-
lers. Two propellers turn clockwise (A) and two propel-
lers turn counter-clockwise (B) when viewed from above.
The arrow pointing up between the two blue
propellers indicates the forward ight direction
of the quadrocopter.
Figure 5

c) Inserting the Flight Battery
Put the quadrocopter onto a soft surface with the un-
derside up.
Then push the charged ight battery (1) into the battery
shaft from the rear according to the adjacent gure.
Important!
The rechargeable battery must be inserted
into the chute to the stop (2) (see illustration
below in gure 6).
Figure 6

15
d) Connecting the Flight Battery
Move the control stick for the pitch and yaw functions
(also see gure 1, item 8) to the bottom position and
switch on the transmitter with the on/off switch (also
see gure 1, item 7). The transmitter emits two short
signals and the transmitter LED (also see gure 1, item
2) ashes.
Put the quadrocopter onto a straight surface (table top,
etc.).
Then connect the plug of the quadrocopter connection
cable (1) that is protected against polarity reversal to the
plug connector of the ight battery (2).
Right after the battery is connected, the LEDs of the two
rear motor arms start to ash red and the LEDs of the
two front motor arms start to ash blue.
Move the control stick for the pitch and yaw functions to
the front position and then back to the bottom position
again at once.
The remote control transmitter emits a signal sound in
the respective stick end positions, and the LEDs at the
quadrocopter and the transmitter LED are now perma-
nently lit.
If the LEDs at the motor arms do not remain lit
after activation but continue to ash, activation
has failed and must be repeated entirely.
Figure 7

e) Basic Information Relevant to the Control of Quadrocopters
Before you y your model, you should rst familiarise yourself with the control possibilities open to you and thereby
be able to y safely.
The symmetrical setup of the model makes it very difcult to assign the alignment (front/rear). Therefore, the two front
propellers are of blue plastic and the two rear propellers of orange plastic. Red and blue LEDs are installed on the
motors in addition to this.
The quadrocopter is controlled via the two control sticks at the remote control transmitter. The following functions are
available:
Pitch Function
With the pitch function you can control the ight altitude of the quadrocopter (see gure 8). The left control stick (also
see gure 1, item 8) is used for control. To that effect, the control stick can be moved forward and backward. Unlike
the other control functions, the stick does not keep springing back to the centre position.
Depending on the control stick position, the speeds of the four propellers change. If the control stick has been pulled
all the way to the body, the motors are switched off.
If you push the control stick from the bottom position forward, the propellers start up and increase the speed according
to the position of the stick.
Once the control stick is in the centre position, the propeller speeds should be high enough for the quadrocopter to
hover.
If the control stick is pushed forward further, the quadrocopter will rise.
If the control stick is pulled back, the quadrocopter drops.
Figure 8

17
Yaw Function
The two right-ward turning and the two left-ward turning propellers balance out the torques acting on the model. The
quadrocopter hovers stably.
If the control stick for the yaw function (also see gure 1, item 8) is moved to the left, the electronics in the model will
increase the speed of the propeller turning to the right (clockwise) viewed from above and at the same time reduce
the speed of the propellers turning to the left (counter-clockwise). This way, the entire lift force remains the same,
but only one torque acts on the model, which turns the quadrocopter around its vertical axis to the left when viewed
from above.
If the control stick is moved to the right, the speed changes of the propellers are precisely the other way around and
the model turns to the right.
Figure 9
Roll function
The roll function allows you to move your quadrocopter sideways to the right and to the left (see gure 10). Use the
right control stick for control (also see gure 1, item 5).
If the stick is slightly moved to the left, the electronics in the quadrocopter change the propeller speeds so that the
model will turn to the left slightly and thus also y to the left.
If you move the transmitter to the right, the speed changes of the propellers are precisely inverted and the model will
y sideways to the right.
Figure 10

18
Nod Function
The nod function allows you to move your quadrocopter forward and backward (see gure 11). This is also controlled
with the right control stick (also see gure 1, item 5).
If the stick is slightly pushed to the front, the electronics in the quadrocopter change the propeller speeds so that the
model will turn to the front slightly and thus also y forward.
If you move the transmitter to the rear, the speed changes of the propellers are precisely inverted and the model will
y to the rear.
Figure 11

19
f) Practical Flight Advice for the First Start
• Even if the model can y in the narrowest spaces, for the rst test ights, we recommend using a free space of about
3 x 3 m.
• The ground or oor should be smooth (tiles, woodblock ooring, PCV or similar) to allow you to tell just before the
helicopter lifts off whether it wants to drift in a particular direction.
• If you perform the rst ight outdoors, you should do so on a perfectly wind-still day.
• Place yourself exactly behind your quadrocopter. As long as the two booms with the orange propellers point towards
you and you thus see your model from behind, it will react to the control commands: right, left, forward, backward
exactly as you see it. Whereas, if the blue propellers of the model points towards you, it reacts exactly the opposite
way from your steering commands at the transmitter from your view.
Important!
Do not pull the control stick for the pitch function down suddenly. This would cause the drive to switch off and
the quadrocopter to drop to the ground, which may cause damage.
If the propellers hit any objects and are blocked, slide the pitch lever into the bottom-most position at once so that the
affected drive motors are no longer supplied with power.
Caution, important!
Never try grabbing the ying quadrocopter with your hand. There is an increased danger of injury!
When the red and blue LEDs at the quadrocopter start to ash in a rhythm of three, the ight battery has reached its
lower voltage limit. In this case, end your ight without delay and charge the ight battery again to avoid harmful deep
discharge of the ight battery.
If you are using the quadrocopter outdoors, observe the ight distance. The farther the quadrocopter moves away
from you, the more difcult it is to recognise the ight position.
Never switch off the remote control while the quadrocopter is still ying. The quadrocopter would otherwise
drop straight to the ground, which may damage it.

g) Trimming the Quadrocopter
First start the transmitter, then the model.
Push the pitch lever (also see gure 1, item 8) from the bottom position (motors off) carefully forward and observe the
response of your model. Shortly before the quadrocopter starts hovering, you can already determine in which direction
your model wants to move.
Roll trimming
If the quadrocopter tries to drift or tip to the right, reduce the speed until the quadrocopter is standing safely on its
landing struts again. Push the left trim button for the roll function several times (also see gure 1, item 6).
Push the pitch stick carefully forward and check if the adjustment was sufcient. Repeat the procedure until the model
does not show any tendency to drift to the right.
If the quadrocopter drifts to the left, push the right trim button for the roll function.
Every time the button is pushed, the trim is adjusted by one step and the adjustment is conrmed by a brief
signal. If the button is pushed and held, the transmitter will continually emit a sequence of signals to indicate
graduals adjustment of the trim. When the nal position of the trim is reached, the transmitter no longer emits
any sounds.
Up to 32 trim steps are available in either direction. The trim middle setting is indicated by a longer signal
sound.
