5. Product description
Theready-to-y“FoldableDroneG-Sense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 the ground
and hover steadily in the air at appropriate propeller speeds.
Forstabilisationinight,thequadrocopterhassophisticatedelectronicswithpositionandaccelerationsensorsallow-
ing the model to detect uncontrolled movements and compensate them immediately. The quadrocopter is equipped
withabarometricairpressuresensorallowingthequadrocoptertostabiliseitsightaltitudeitself.
Fortheightinacertaindirection,theelectronicsinthemodelrecognise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propulsion.Thequadrocopteriesintherespectivedirection.Thetransmitteriscontrolledbya
joystick, as well as by tilting and tipping the hand-held transmitter. The transmitter has a built-in G-sensor that detects
the movement.
On the model, two propellers rotate clockwise and two rotate counter-clockwise. Through a targeted change of speed
of the two propeller groups relative to each other (propellers rotating to the right rotate somewhat faster and propel-
lers rotating to the left rotate somewhat slower or vice versa), it is possible to turn (yaw) the quadrocopter around
the vertical axis while keeping the same altitude and the quadrocopter at the same spot. The quadrocopter can even
performsidewaysips,ifnecessary.
The 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 videos via Wi-Fi to a suitable smartphone
(notincluded)duringtheight.Ifnecessary,thesmartphonecanalsobeusedtocontrolthequadrocopter.
To operate the transmitter, you need 2 Micro/AAA non-rechargeable batteries.

today, there are numerous hazards and problems.
Therefore, always observe the following general information and safety instructions when handling
non-rechargeable and rechargeable batteries.
• Keep non-rechargeable/rechargeable batteries out of the reach of children.
• Do not leave non-rechargeable/rechargeable batteries lying around, as they present a choking hazard
for children and pets. Seek immediate medical advice if a battery is swallowed!
• Non-rechargeable/rechargeablebatteriesmustneverbeshort-circuited,takenapartorthrownintore.
There is a risk of explosion!
• When handling leaking or damaged non-rechargeable/rechargeable batteries, always use suitable pro-
tective gloves to avoid burning your skin.
• Donotattempttorechargeconventionalnon-rechargeablebatteries.Thismaycauseareorexplosion!
Only charge rechargeable batteries which are intended for this purpose (1.2 V); use suitable battery
chargers. Non-rechargeable batteries (1.5 V) are designed to be used once and must be disposed of
properly when they are empty.
• Pay attention to the correct polarity when inserting non-rechargeable batteries (observe plus/+ and mi-
nus/-). Incorrect polarity will not only damage the transmitter and non-rechargeable batteries. It may also
causeareorexplosion.
• Always replace the entire set of non-rechargeable batteries. Do not mix full non-rechargeable batteries
with half-full batteries. Always use non-rechargeable batteries of the same type and from the same
manufacturer.
• Never mix non-rechargeable batteries with rechargeable batteries. Always use non-rechargeable batter-
ies to power the remote control.
• If you do not plan to use the model for an extended period (e.g. during storage), remove the non-
rechargeable batteries from the remote control to prevent them from leaking and causing damage.
• Switchoffthequadrocopteraftertheightandremovetheightbatteryfromthequadrocopter.Donot
leavetheightbatteryinthequadrocopterwhenyouarenotusingthemodel(e.g.duringtransportor

10. Operating the quadrocopter
a) Charging the ight battery
TheightbatterycanbechargedusingtheincludedUSBchargingcable.
 ThechargingcableinFigure4iswoundupforphoto-technicalreasons.Beforerstuse,removethecable
tie and fully unwind the charging cable.
Charging:
Connect the USB plug of the charging cable (1) to a USB
port of a computer/laptop or a USB charger plug.
The LED charging indicator on the USB plug (2) will go on
to indicate that the USB charging cable is supplied with
the correct voltage.
Connect the 2 mm barrel connector (3) of the charging
cabletothechargingsocket(4)oftheightbattery(5).
Charging will now start automatically and the LED charg-
ing indicator on the USB plug (2) will go out.
TheredLEDontheUSBplugwillgoonwhentheight
battery is fully charged.
Disconnectthechargingcablefromtheightbatteryim-
mediately after charging and unplug the USB plug of the
charging cable from the computer/laptop or charger plug.
Caution!
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ightbattery.
The operating system will not recognise any new hardware
when the charging cable is connected, as the USB port
isonlyusedtochargetheightbattery.Pleasenotethat
most USB ports on computers/laptop are only active when
the computer/laptop is turned on.
We therefore recommend that you only connect the charging cable to a computer/laptop that is turned on.
Important!
 Onlychargetheight battery in thequadrocopterusingtheincludedcharging cable. Never attemptto
charge the rechargeable battery in the quadrocopter with a different or unsuitable charger!
Figure 4

b) Folding the rotor arms in and out
The propeller arms with the propellers and guards can be folded in for space-saving transport (see Figure 5A).
The front and rear propeller arms on each side are mechanically interconnected and folded in and out together (see
Figure 5B).
Whenbothsidesareunfolded,thequadrocopterliesatonthesurface(seeFigure5C).
Figure 5
c) 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function
ofthedrivepropellersbeforeeachight.
To dothis,rotate each individual propellercarefullywith your ngerandcheckthe concentricity andtheeaseof
movement.
When doing this, pay attention to the directions of rotation
of the various propellers. Two propellers rotate clockwise
as viewed from above (A) and two propellers rotate coun-
ter-clockwise (B).
Figure 6

15
d) Inserting the ight battery
Mount the ight battery (1) on the quadrocopter from
above.
It is important that the connection contacts (2) of the quad-
rocopter engage securely in the connection socket (3) of
theightbattery.
Theightbatterylockistakenoverbytwolockinglatches
(4)onthesidesoftheightbattery.
To remove the rechargeable battery, slightly press the two
groovedsurfaces(5)ontherightandleftoftheightbat-
tery inwards and lift off the rechargeable battery.
Important!
If you do not use the quadrocopter, e.g. dur-
ing transport and storage, always remove the
rechargeable battery from the quadrocopter.
Figure 7

16
e) Switching on the quadrocopter
So that the receiver in the quadrocopter can respond to the transmitter signals, the receiver and the transmitter must
have the same digital coding (pairing). For this reason, it is important that you switch on the quadrocopter as described
below.
Firstinsertthechargedightbatteryintothequadrocopterasdescribedaboveandplacethequadrocopteronalevel
surface.
Press and hold down the function button (2) on the quad-
rocopter until the green LED (3) at the rear of the quadro-
copterstartstoash.
Then press the push button for the on/off function on the
remote control transmitter (see also Figure 1, no. 5). The
red LED on the hand-held transmitter (see also Figure 1,
no.4)willash.
Then push the joystick for the pitch and yaw function (see
also Figure 1, no. 1) all the way up. The transmitter will
emit a beep and the green LED on the quadrocopter will
ashfaster.
Then move the joystick all the way down. The transmitter
will emit another beep and the red LED indicator on the
transmitter will glow steadily.
The green LED on the quadrocopter will also glow steadily
after successful pairing.
Shortly thereafter, a blue LED below the function button
will signal the operational readiness of the camera module.
The quadrocopter is ready to start.
Important!
There should be no other 2.4 GHz transmitters in the immediate vicinity during the switch-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 on the quadrocopter until the green
LED at the rear goes out. Now you can also switch off the transmitter.

f) 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 using the joystick on the remote control transmitter and the movement of the transmit-
ter. The following functions are available:
Pitch function
Withthepitchfunction,youcancontroltheightaltitudeofthequadrocopter(seeFigure9).Usethejoystickforsteer-
ing (see also Figure 1, no. 1).
When the motors are started by a remote control command, they are idling. If the joystick is now pushed forwards from
itsmiddleposition,thepropellerswillspeedupandthequadrocopterwillliftoff.Oncethedesiredightaltitudehas
been reached, the joystick can be returned to the middle 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 will ascend. When the joystick is pulled back, the quadro-
copter descends (see arrows in Figure 9).
Figure 9

18
Yaw function
The torques that act on the model are balanced by the two right-rotating and the two left-rotating propellers, and the
quadrocopter hovers steadily in the air.
When the joystick is moved to the left (see also Figure 1, no. 1), 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). Thus, the total lift remains the same, but now a torque acts on the model turning the quadrocopter about
the vertical axis to the left, as seen from above (see arrows in Figure 10).
When the joystick is moved to the right, the propeller speeds are changed exactly the opposite and the model turns
to the right.
Figure 10
Roll function
The roll function allows you to move the quadrocopter sideways to the right and to the left (see Figure 11). Move the
remote control transmitter for steering.
When the transmitter is tilted to the left around the longitudinal axis, 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11).
When the transmitter is tilted to the right around the longitudinal axis, the propeller speeds are changed exactly the
oppositeandthemodeliessidewaystotheright.
Figure 11

19
Pitch function
The pitch function allows you to move your quadrocopter forward and backward (see Figure 12). Move the remote
control transmitter for steering.
When the front of the transmitter is tilted downwards, the quadrocopter electronics change the propeller speeds so
thatthemodeltiltsslightlyforwardandthusalsoiesforward(seearrowsinFigure12).
When the front of the transmitter is lifted up, the propeller speeds are changed exactly the opposite and the model
iesbackward.

g) Practical ight tips for the rst start
Calibrate the position sensors before each start. The exact procedure is described in the following chapter.
Althoughthemodelcanbeowninaveryconnedspace,werecommendusinganunobstructedspaceofapprox.
3x3mfortherst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ascendtoeyelevelafterstart-up.Thisenablestheightattitudetoberecognisedoptimally
andthequadrocopterismorestablethanatgroundlevel.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 hit any objects and become blocked, turn off the drive motors immediately so that they are
no longer supplied with power.
Caution!
 Nevertrytograbholdoftheyingquadrocopterwithyourhands.Thereisanincreasedriskofinjury!
WhenthegreenLEDattherearofthequadrocopterstartstoash,theightbatteryhasreacheditslowervoltage
limit.Inthiscase,stoptheightoperationimmediatelyandrechargetheightbatteryinordertoavoiddeepdischarge
thatcandamagetheightbattery.
Ifthequadrocopterisusedoutdoors,payattentiontotheightdistance.Thefurtherawaythequadrocopterisfrom
you, the harder it is to recognise the attitude. In addition, the wireless remote control has a limited range of approx.
30 – 50 m.
Neverswitchoffthetransmitterwhilethequadrocopterisying.
