5. Product description
Theready-to-y"R5-FoldableFPVDroneRtF"quadrocopterfeatures4separatelycontrolledmotors,eachofwhich
drives its own propeller. Using the simultaneous acceleration of all propellers, the quadrocopter can lift off from the
ground and, at appropriate propeller speeds, hover steadily in the air.
Forstabilisationinight,thequadrocopterhassophisticatedelectronicswithpositionandaccelerationsensorsal-
lowing you to detect uncontrolled movements of the model and compensate them immediately. The quadrocopter is
equippedwithabarometricairpressuresensorallowingthequadrocoptertostabiliseitsightaltitudeitself.
Forightinagivendirection,theelectronicsinthemodeldetectthecontrolimpulsesofthetransmitterandalterthe
speeds of the individual motors accordingly. The quadrocopter thus tilts in the desired direction and the lift thereby also
actsasthrust.Thequadrocopteriesintherespectivedirection.
On the model, two propellers turn clockwise and two turn anti-clockwise. Through a targeted change of speed of the
two propeller groups relative to each other (propellers turning to the right turn somewhat faster and propellers turning
to the left turn somewhat slower or vice versa), it is possible to turn (yaw) the quadrocopter around the vertical axis
while keeping the altitude the same and keeping the quadrocopter in the same spot. If required, the quadrocopter can
evendoroll-overs(ips).
Four propeller arms can be folded for easier transport, which means that the model can be transported in a very
space-saving manner.
The quadrocopter has an integrated HD camera, which transfers images or even videos via Wi-Fi to a suitable smart-
phone(notincluded)duringtheight.Ifnecessary,thesmartphonecanalsobeusedtocontrolthequadrocopter.
To operate the transmitter, you require 3 AAA/Micro type batteries (e.g. Conrad Item No. 652278, please order 3x).

9. Using the remote control
The numbers used in these instructions refer to the illustration alongside the text or the illustrations within
therespectivesection.Crossreferencestootherguresareindicatedwiththecorrespondingnumber.
The illustrations of the remote control and the model in this manual are for illustrative purposes only. The label, design
and colour scheme of the products supplied in series may differ completely from the illustrations in this manual.
a) Inserting the batteries
To power the transmitter, you require 3 AAA/Micro type batteries (e.g. Conrad Item No. 652278, please order 3 x).
Important!
Use only standard batteries (1.5 V/cell) and not rechargeable batteries (1.2 V/cell) as the power supply for
the transmitter.
To insert the batteries, proceed as follows:
Loosen the retaining screw (1) on the battery compart-
ment cover (2) on the back of the transmitter with a suit-
able screwdriver.
Press the latch (3) of the lid locking mechanism down and
remove the battery compartment cover.
Insert 3 AAA/Micro type batteries with correct polarity fol-
lowing the instructions on the bottom of the battery com-
partment (4). The spiral spring contact (5) must always be
connected to the negative pole of the battery.
Replace the battery compartment cover (2) again and al-
low the locking mechanism to lock into place in the trans-
mitter housing.
Re-tighten the retaining screw (1).
Figure 2

12
b) Switching on the remote control
Slide the on/off switch (see also Figure 1, no. 8) from the
left position (OFF) to the right position (ON).
The transmitter emits a short beep and the LED indicator
(seealsoFigure1,no.15)startstoash.
Then the transmitter emits another short beep with a high-
er frequency and the LED glows steadily.
Then, switch off the transmitter again using the on/off
switch.
Ifthepower supply isnolongersufcient for theproper
operation of the transmitter, the LED indicator (see Figure
3, no. 15) will start to ash and the transmitter will emit
short beeps.
Inthiscase,stopyingthequadrocopterimmediatelyand
insert a new set of batteries into the transmitter.
Figure 3

10. Operating the quadrocopter
a) Charging the ight battery
TheightbatterycanbechargedusingtheUSBcableprovided.
 ThechargingcableinFigure4iswoundup.Beforerstuse,removethecabletieandfullyunwindthe
charging cable.
Charging:
Connect the reverse polarity protected plug connector (1)
ofthechargingcabletothechargingsocketoftheight
battery (2).
As soon as the USB plug on the charging cable (3) is con-
nected to a USB port on a computer/notebook or to a USB
charger plug, charging begins automatically.
The red charging indicator LED (4) on the USB plug lights
up and indicates that charging has started. When charging
iscompleteandtheightbatteryisfullycharged,thered
LED of the USB plug goes out.
Disconnecttheightbatteryfromthechargingcableim-
mediately after charging and unplug the USB plug on the
charging cable from the computer/laptop or charger plug.
Warning!
Do not connect the USB cable to a USB hub
without its own power supply (e.g. a USB port
onakeyboard),asthecurrentisnotsufcient
to charge the battery.
The operating system will not detect any new hardware
when the charging cable is connected, as the USB port
is only used to charge the battery. Please note that most
USB ports on computers/laptop are only active when the
computer/laptop is switched on.
We therefore recommend that you only connect the charg-
ing cable to a computer/laptop that is switched on.
Important!
 Onlychargetheightbatteryinthequadrocopterusingtheenclosed chargingcable.Neverattemptto
charge the battery in the quadrocopter with a different or unsuitable charger!
Figure 4

b) Folding the rotor arms in and out
Four propeller arms can be folded in for space-saving transport (see Figure 5 A).
Whenunfolding,thetwofrontpropellerarmsmustrstbefoldedoutasviewedinightdirection(seeFigure5B).The
arms will automatically lock into place in the end position.
Thenthetworearpropellerarmscanbefoldedoutasviewedinightdirection(seeFigure5C).
Figure 5
First the two rear propeller arms and then the two front propeller arms are folded in for transport.
c) Attaching the propeller guard
The quadrocopter comes with two plastic guards (1) that
ensure protection against rotating propellers.
Slide the plastic guards over the landing legs from below
until the two latches (2) lock into place on the guard holder
of each motor.
For better illustration, Figure 6 shows a guard already
mounted.
To disassemble the guard, slightly open the two latches
oneachmotorwithangernailorasmallscrewdriverand
push down the holder.
Important note:
Even when the quadrocopter is shown without
the protective guard in these instructions for il-
lustrative purposes, you should always use the
quadrocopter with the propeller guards mount-
ed for safety reasons.
Figure 6

15
d) Checking the drive
Before starting the quadrocopter, you must test the drive.
Only when all four propellers run smoothly and in a perfect
circle can the model be own with the minimum energy
consumption. For this reason, you should check the func-
tionofthedrivepropellersbeforeeachight.
To do this, turn each individual propeller carefully with your
ngerandchecktheconcentricityandtheeaseofmove-
ment.
When doing this, pay attention to the rotational directions
of the various propellers. Two propellers turn clockwise
when seen from above (A) and two propellers turn anti-
clockwise (B).
e) Inserting the ight battery
Toinsertthechargedightbattery(1)easily,turnthequad-
rocopter on its back.
Mounttheightbatteryonthequadrocopterasshownin
Figure 8 above. Then slide it forward until it locks into place
in the holder.
To remove the rechargeable battery, press on the grooved
surface (2) with your thumb and push the rechargeable
battery backwards. At the same time, make sure that you
do not press the on/off switch of the quadrocopter with
yourforenger(seeFigure9,no.1).
Important!
If you will not be using the quadrocopter, e.g.
during transport and storage, always remove
the rechargeable battery from the quadrocop-
ter.
Figure 7
Figure 8

f) Switching the quadrocopter on
So that the receiver in the quadrocopter can react to the
signal transmitted, the receiver and the transmitter must
have the same digital coding (pairing). For this reason, it
is important that you switch the quadrocopter on as de-
scribed below.
Firstinsertthechargedightbatteryintothequadrocop-
terasdescribedaboveandsetthequadrocopteronaat
base.
Press and hold down the function button of the quadrocop-
ter (1) for approx. 1 second.
The LED below the function button will go on.
Then use the on/off switch to switch on the transmitter (see
also Fig. 1, no. 8). The transmitter will then be paired with
the quadrocopter.
If the LEDs on the transmitter and the quadrocopter glow
steadily, the quadrocopter is ready to start.
Important:
 Thereshouldbenoother2.4GHztransmitters
in the immediate vicinity during the switching on
process. The quadrocopter must not be moved
or turned during the switch-on process.
To switch off the quadrocopter, press and hold
down the function button for approx. 1 second.
When the button is released, the LED on the
quadrocopter goes out. Now you can also
switch the transmitter off.

g) Basic information on steering quadrocopters
Beforestartingyourmodelforthersttime,youshouldrstfamiliariseyourselfwiththecontrolfeaturesavailableto
you to be able to control the model in a safe manner.
The quadrocopter is controlled via the two joysticks on the remote control transmitter. The following functions are
available:
Altitude function
Withthepitchfunctionyoucancontroltheyingheightofthehelicopter(seeFigure10).Steeringiscarriedoutwith
the left joystick (see also Figure 1, no. 12).
When the motors are started by remote control, they run at idle speed. If the joystick is now pushed forwards from its
centralposition,therotationalspeedsofthepropellersincreaseandthequadrocopterliftsoff.Oncethedesiredight
altitude has been reached, the joystick can be returned to the centre position. Thanks to its barometric sensor, the
quadrocoptercannowhoveratanearlyconstantightaltitude.
If the joystick is moved further forwards, the quadrocopter ascends. When the joystick is pulled back, the quadrocopter
descends (see arrows in Figure 10).
Figure 10

18
Yaw function
The torques that act on the model are balanced by the two right-turning and the two left-turning propellers, and the
quadrocopter hovers steadily in the air.
When the joystick is moved to the left for the yaw function (see also Figure 1, no. 12), the model electronics speed
up the propeller rotating to the right (clockwise) as viewed from above and simultaneously slow down the propeller
rotating to the left (counter-clockwise). As a result, the entire lifting force remains the same, but the model now has a
torque that turns the quadrocopter around the vertical axis to the left as viewed from above (see arrows in Figure 11).
If the joystick is moved to the right, the speed changes of the propellers come out exactly the opposite and the model
turns to the right.
Figure 11
Roll function
The roll function allows you to move the quadrocopter sideways to the right and to the left (see Figure 12). The control
is effected with the right joystick (see Figure 1, no. 4).
When the joystick is moved slightly to the left, the quadrocopter electronics change the propeller speeds so that the
modeltiltsslightlytotheleftandthusalsoiestotheleft(seearrowsinFigure12).
If you steer to the right on the transmitter, exactly the opposite speed changes of the propellers occur and the model
iessidewaystotheright.
Figure 12

19
Pitch function
The bob function allows you to move your model helicopter forward and backward (see Figure 13). This steering is
carried out with the right joystick (see also Figure 1, no. 4).
When the joystick is pushed slightly forward, the quadrocopter electronics change the propeller speeds so that the
modeltiltsslightlyforwardandthusalsoiesforward(seearrowsinFigure13).
If you steer backward on the transmitter, exactly the opposite speed changes of the propellers occur and the model
iesbackward.

h) Practical ight tips for beginners
Althoughthemodelcanbeowninsmallrooms,werecommendusingaunobstructedspaceof3x3mfortherst
fewightattempts.
Whenyingthequadrocopteroutdoorsforthersttime,thereshouldbeabsolutelynowind.
Place yourself directly behind your quadrocopter. For as long as you see your model from behind, it will respond from
your perspective to the right, left, forward and backward control commands just as you steer the transmitter. However,
if you face the camera of your model, the model will respond from your perspective exactly the opposite as you steer
the transmitter.
Allowthequadrocoptertoclimbtoeyelevelafterstartup.Thisenablestheightattitudetobedetectedoptimally
andthequadrocopterisvisiblymorestablethanatgroundlevel.Thisisbecause,ifthequadrocopteriessolowthat
theairblowndownwardsbythepropellersreachestheground(groundeffect),theightattitudeissignicantlymore
unstable.
If the propellers bump against objects and get blocked, immediately press the push button for the motor
emergency stop function (see Figure 1, no. 10) so that the drive motors are no longer supplied with power.
After a clumsy landing or a crash, the quadrocopter cannot be started for approx. 10 seconds. During this time, the
position sensors are automatically recalibrated. This process can be shortened by manual calibration. The procedure
is described in detail in one of the following chapters.
Important!
 Nevertrytograbholdoftheyingquadrocopterwithyourhands.Thereisanincreasedriskofinjury!
WhentheLEDnearthefrontrotorarms(seeFigure17,no.1)startstoash,theightbatteryhasreacheditslower
voltagelimit.Inthiscase,stopightoperationandchargetheightbatteryagaininordertoavoiddeepdischargethat
candamagetheightbattery.
Ifthequadrocopterisusedoutside,payattentiontotheightdistance.Thefurtherawaythequadrocopterisfrom
you, the harder it is to detect the attitude. In addition, the wireless remote control has a limited range of approx. 30 m.
Neverswitchthetransmitteroffwhilethequadrocopterisying.
