4. Product description
The"GravityFPV"quadrocopterisapre-assembledhelicopter-likemodelaircraftwithfourrotorsandabuilt-incam-
era.Professionally,suchyingdevicesarealreadybeingusedforvarioustasks.Thefourrotorwingscanberetracted.
This makes the quadrocopter especially transport friendly.
The latest microprocessor-controlled electronics with position control and acceleration sensors stabilise both the
positionandaltitudeofthequadrocopter.Positionsensorsareinstalledinthehand-heldtransmitterforthe"roll"and
"nod" functions. The control of said functions occurs when there is a change in position of the transmitter. The inbuilt
quadrocoptercameraallowsaso-called"FPVoperation"(FPV=rstpersonview=yingusingthevideo)througha
live transmission. There is even the option for control via your smartphone. Taking images and videos is also possible.
High-qualityDCmotorsinconjunctionwithaspeciallydevelopedactuatorresultinapowerfulightoperation.The
novelcontrolsandelectronicself-stabilisationresultinexcellentightcharacteristics.
The product is designed for use in large enclosed rooms/halls, but can also be used outdoors when there is no wind.
Thein-builtelectroniccontrols(built-ingyro)canbalanceoutsmallundesiredchangestotheightaltitude,butcannot
eliminate them completely. Due to the low weight of the quadrocopter, it reacts sensitively to wind or draughts.
The quadrocopter is powered by a LiPo rechargeable battery. The LiPo rechargeable battery can be charged using

7. Information relevant to (rechargeable) batteries
Batteries present numerous safety hazards. Compared with conventional NiMH rechargeable bat-
teries, LiPo/Li-ion rechargeable batteries have a high energy content. For this reason, it is essential
to comply with safety regulations to prevent the risk of a re or explosion.
Always observe the following safety information when handling batteries.
a) General information
• Keep batteries out of the reach of children. Batteries must be kept out of the reach of children.
• Do not leave batteries lying around, as they present a choking hazard for children and pets. Seek im-
mediate medical advice if a battery is swallowed.
• Batteries/rechargeablebatteriesmustneverbeshort-circuited,takenapartorthrownintore.Danger
of explosion!
• When handling leaking or damaged batteries, always use suitable protective gloves to avoid burning
your skin.
• Liquidsleakingfrombatteriesareverychemicallyaggressive.Objectsorsurfacesthatcomeintocontact
with these liquids could become seriously damaged. Always store batteries in a suitable location that is
not prone to damage.
• Donotattempttorechargedisposable,non-rechargeablebatteries.Thismaycauseareorexplosion!
Non-rechargeablebatteriesareonlydesignedtobeusedonceandmustbedisposedofproperlywhen
they are empty. Only recharge compatible rechargeable batteries and ensure that you use a suitable
battery charger.
• If you do not plan to use the vehicle for an extended period, remove the batteries from the remote control
to prevent them from leaking and causing damage. Store the product in a dry, clean and cool place that
is out of the reach of children. The same applies to batteries/rechargeable batteries.
Installasmokedetectorintheroom.Batteriespresentarehazardandmaygeneratetoxicfumes.This
appliesinparticulartobatteriesformodeltoys,whicharesubjectedtohighcharging/dischargecurrents
and vibrations.
• Alwaysexchangetheentiresetofbatteriesintheremotecontrol.Donotmixfullbatterieswithhalf-full
ones. Always use batteries of the same type and from the same manufacturer. Never mix disposable
batteries with rechargeable batteries.
• Pleaseobservecorrectpolarity(plus/+andminus/-)wheninsertingthebatteries/rechargeablebatteries
into the transmitter.
• Donotexposethechargerandthequadrocopter/rechargeableightbatterytohigh/lowtemperatures
or direct sunlight.
• Batteries must not become damp or wet. The same applies to the charger and the quadrocopter/re-
chargeableightbattery.Thechargermustonlybeusedindry,enclosedindoorareas.
Lithiumrechargeablebatteries(e.g.LiPo/Li-ionbatteries)areespeciallysensitivetomoisturebecause
of the chemicals they contain.

11
• Placethechargerandthequadrocopter/rechargeableightbatteryontoanon-ammable,heat-resistant
surface(e.g.stonetiles).Keepthechargerandbatteryawayfromammableobjects.Leaveenough
distancebetweenthechargerandthequadrocopter/rechargeableightbattery.
• Do not charge batteries when they are still hot (e.g. due to a high discharge current in the model). Allow
therechargeableightbatterytocooldowntoroomtemperaturebeforechargingit.
• Asthechargeraswellastherechargeableightbatteryheatupduringthechargingprocedure,itis
necessarytoensuresufcientventilation.Nevercoverthechargerandtherechargeableightbattery!
• Never leave batteries unattended when they are charging. Inspect the charger at regular intervals to
ensurethat the battery is notoverheating or expanding. This indicates animminent risk of a reor
explosion.Iftherechargeableightbatteryoverheatsorstartstoexpand,disconnectitfromthecharger
immediately and take it to a location where it will not cause any additional damage if it explodes or
catchesre(e.g.outdoors).
• Disconnecttherechargeableightbatteryfromthechargerwhenthebatteryisfullycharged.
• Never damage the casing of a rechargeable battery. Never charge damaged, leaking or misshapen bat-
teries.Thismaycauseareorexplosion!Discontinueuseimmediatelyanddisposeofthebatteryinan
environmentally friendly manner.
• Rechargeable batteries should be charged regularly (approx. once every 2–3 months) to prevent them
from overdischarging. This may result in permanent damage and render the batteries useless.
LiPo/Li-ion batteries usually retain their charge for several months. However, if the batteries
overdischarge, this will result in permanent damage and render them useless.
b) Additional information about lithium rechargeable batteries
Modern lithium rechargeable batteries have a signicantly higher capacity than NiMH and NiCd bat-
teries and are more lightweight. This makes LiPo (lithium polymer) or Li-ion batteries particularly
suitable for use in the model making industry.
However, lithium batteries require particular care to ensure safe charging/discharging, operation
and handling.
The following section provides an overview of the potential hazards associated with lithium batter-
ies and explains how these hazards can be avoided to ensure a long lifespan.
• Thecasingofmanylithiumbatteriesismadeofathicklm,whichisverysensitive.Donotdismantle,
droporinsertanyobjectsintolithiumbatteries.Donotapplymechanicalloadsorpullonthebattery’s
connectioncables.Thismaycauseareorexplosion!
• Therechargeableightbatterycaneitherbechargedseparatelyorinsidethequadrocopter.Sincethe
rechargeableightbatteryisscrewedintothequadrocopter,werecommendthatyouchargethere-
chargeableightbatteryinsidethequadrocopter.Thiswayitwillnotneedtobeunnecessarilydisman-
tled.
• Ensure that a lithium rechargeable battery does not overheat during use, recharging, discharging, trans-
portorstorage.Donotplacetherechargeableightbattery(orthequadrocopterwiththerechargeable
ightbatteryinside)nearheatsourcesandkeepitawayfromdirectsunlight.Thismaycausethebattery
tooverheat,whichcancauseareorexplosion!Thetemperatureoftherechargeablebatterymust
never exceed +60 °C.

12
• If the rechargeable battery is damaged or the outer casing is swollen (e.g. due to a crash causing dam-
agetothequadrocopter),donotrechargeit.Thismaycauseareorexplosion!
Neverstoreadamagedrechargeableightbatteryinanapartmentorinahouse/garage.Damagedor
swollenlithiumbatteriesmaycatchre.
• Alwaysuseacompatiblechargertochargelithiumbatteriesandensurethatthechargingspecications
arecorrect.DonotuseNiCd,NiMHorlead-acidbatterychargers,asthesemaycauseareorexplo-
sion!Alwaysselectthecorrectchargingspecicationsforyourrechargeablebattery.
• Ifyouchargearechargeablelithiumbatterywithmorethanonecell,besuretouseaso-calledbalancer
(the rechargeable battery supplied with the quadcopter has only one cell).
• ThechargerateforLiPo/Li-ionbatteriesmustnotexceed1C(orthevaluestatedinthebatteryinstruc-
tions). This means that the charging current must not exceed the battery capacity (e.g. battery capacity
=1000mAh,max.chargingcurrent=1000mA=1A).
• The discharge current must not exceed the value stated on the battery.
Forexample,if"20C"isprintedontheLiPo/Li-ionbattery,themaximumdischargecurrentis20times
thebattery'scapacity(e.g.batterycapacity=1000mAh,max.dischargecurrent=20C=20x1000mA
=20A).
Exceeding the maximum current may cause the battery to overheat or become misshapen, which can
leadtoareorexplosion!
The printed value (e.g. 20C) indicates the maximum current that the battery can deliver for a short period.
The continuous current should not be higher than one half of the stated value.
• Make sure that a lithium rechargeable battery does not become deeply discharged. This may destroy the
battery or cause permanent damage.
If your model does not have overdischarge protection or a low battery indicator, stop using it before the
battery becomes empty.

8. Preparation for takeoff
a) Inserting batteries into the transmitter
Remove the battery compartment cover on the rear side of the trans-
mitter. To do this, you must slide the lid out to the rear (A). Only then
can the battery compartment lid can be lifted off.
Insert two AAA/micro batteries, observing the correct polarity (B). Ob-
serve the polarity markings in the battery compartment.
Then replace the battery compartment cover correctly (C).
Operation of the transmitter with rechargeable batteries is
notrecommendedduetothelowercellvoltage(battery=
1.5V,rechargeablebattery=1.2V)andtheself-discharge
of rechargeable batteries. Doing so would result in a rapid
message from the transmitter indicating the low state of
charge of the transmitter power supply.
The remote control only uses a small amount of electricity,
thereforedisposablebatterieswilllastsignicantlylonger.
Werecommendusinghigh-qualityalkalinebatteries.
b) Charge ight accumulator
The charging socket is integrated directly into the rechargeable battery
housing. The rechargeable battery is not installed in the model at the
factory and can be connected directly to the charger for initial charg-
ing. For ight operation, the rechargeable battery must be inserted
intothebatterycompartmentasshowningure2andsecuredagainst
loosening with a screw (A).
To charge the rechargeable battery, it must not be removed; the bat-
tery is charged directly in the quadrocopter (the blade in front of it must
be unfolded).
To power the included USB charger, use a suitable USB power
adapter, USB cigarette lighter adapter, or USB hub with its own power
adapter (not included) with an output current of at least 1000 mA.
Switch off the quadrocopter. Then connect the USB plug of the USB
charger (B) supplied to the USB power supply. Finally, connect the
small plug (C) of the USB charger to the corresponding socket (D) of
therechargeableightbattery.
The charging process will begin provided that the battery is not defective (high impedance/disconnected) and that
the battery charger is connected to a power supply. The red LED indicator on the battery charger lights up to indicate
that the battery is charging.
• LED on: The battery is full/fully charged
• LED off: Battery is charging

c) Final assembly
Themodelisdeliveredreadytoy.
It comes with retractable rotor blades as a special feature. The packaged
size is very small as a result, thus facilitating transport.
Forightoperation,therotorsmustbeunfoldedoneaftertheotheruntil
you can hear and feel them engage.
For transport or storage, you can easily fold in the rotors one by one.

10. Safety equipment
The "Gravity FPV" Quadrocopter is equipped with a range of safety devices in the transmitter and model
which protect the model aircraft from damage and/or reduce possible damage to a minimum. The protec-
tive mechanisms are indicated by LED display (model aircraft) or with an optical/acoustic warning signal
(transmitter).
a) Transmitter
The state of the batteries is constantly checked when the transmitter is in operation. If the voltage level of the bat-
teriesdropsbelowacertainvalue,thetransmittersignalsthiswithapermanentashingoftheLEDsonthecontrols
(gure4,item2).Inaddition,awarningsignalsounds("didi").Inthiscase,youshouldimmediatelystopyingand
replace the batteries in the transmitter.
b) Model
The LEDs in the quadrocopter (in the body) indicate whether the transmitter is "bound" to the model and if there is a
goodreceptionofthetransmittersignal.ThisisindicatedbypermanentlylitLEDs.IftheLEDsareashing,itmeans
thatthequadrocopterisnotreceivingthetransmittersignalcorrectly.Inthiscase,theso-called"binding"procedure
must be carried out again.
Thequadrocopterconstantlymonitorsthevoltageoftheinsertedrechargeableightbattery.Whentherechargeable
battery is fully charged, all LEDs in the body of the model are lit (if the LEDs are switched on). If the rechargeable
batteryvoltagefallsbelowacriticalvalueoveracertainperiodoftime,thisisindicatedbytheLEDsashing(forsafety
reasons, this occurs regardless of whether the LEDs have been switched off).
If the undervoltage is permanently below a certain value, an emergency landing is initiated after a short period of time
and the motors are switched off.
 IftheundervoltageonthequadrocopterisindicatedbytheLEDsashing,onlyabout20to30seconds
yingtimeremainstoautonomouslyythemodelbacktothestartingpointandlandit.
 Whenacertainvoltagevalueoftherechargeableightbatteryisreached,motorcontrolisswitchedoff
bythetransmitterandanautomaticlandingisinitiated.Thisprocesscannolongerbeinuencedbythe
transmitter.
 Ifthemodelisaboveabodyofwater,tree,house,road,people,animals,etc.and/orthemodelisying
more than one metre above ground at this time, there is a risk of damage to or loss of the model as well as
propertydamageandinjurytosurroundingpeople/animals.
If the model lands on its rear in a failed landing (rotors point to the ground), the motors will switch off. In addition, you
have the option of switching off the motors immediately by pressing and holding the "start rotors/automatic landing"
button (Figure 4, item 4, press control lever from above like a normal button).
Alternatively,youcanswitchoffthemotorsimmediatelyusingthecorrespondingbutton(gure4,item8).
There is a separate icon in the app for this purpose.

11. Information about rst take-off
To make the explanation of the controls simpler and more consistent, the classic terms are used here.
These come from aviation language and are widely used.
Direction designations are always to be understood from the perspective of a "virtual" pilot in the model.
The two red LEDs in the body are used as direction pointers and mean "back".
The "roll" and "nod" functions (see explanations below) are activated
usingthepositionsensorsofthehand-heldtransmitter.
 Thisiswhyitisimportantthatbeforeeverystartthehand-heldtrans-
mitter is not tilted forwards/backwards or to the left/right but lies hori-
zontally in the hand (see picture 5).
 Otherwise,themodelwouldhoverinthedirectioninwhichthehand-
held transmitter points.
a) Hover ight
Hoveringisdenedastheightconditionat whichthequadrocopterneitherascendsnordescendsandthusthe
upward directed buoyancy force is equal to the downward force of gravity.
Starttherotorsbypushingthecontrollever(picture4or6,item4)fromtoptobottomonthehand-heldtransmitter
untilyouhearacontroltone.Holdthehand-heldtransmitterhorizontally(seealsogure5andthepreviousnotes).
Push this control lever forward. This increases the motor speed and causes the quadrocopter to ascend. When you
pull the control lever backwards, the quadrocopter descends. If you leave the control lever in the central position, the
quadrocopterwilltrytomaintainthesamealtitudewithitsbuilt-insensors.
Figure 6
 Duringaightjustabovethegroundasduringtakeoff,turbulenceandaircurrentsarecreatedthatcanaf-
fect the quadrocopter. This results in a faster response time to the control movements and a slight forward,
back or side swerve of the quadrocopter.
 Thisso-calledgroundeffectisnolongerpresentfromanaltitudeofabout50cm.

b) Yaw function
"Yaw" denotes the rotation of the quadrocopter around the vertical axis. This movement either occurs unintentionally
duetothetorqueoftherotorsorintentionallyasaightdirectionchange.Themovementoccursinthequadrocopter
by speed differences from one individual rotor to another.
Ifyoumovethecontrollever(gure4or7,item4)totheleft,thequadrocopterwillturnleft.Ifyoumovethecontrol
lever to the right, the quadrocopter will turn right.
Figure 7
c) Nod function
"Nod" is the movement about the transverse axis, comparable
to the nodding motion of a head. As a result, the quadrocopter
gainsforwardorreverseightspeedorbrakes.
If you move the hand-held transmitter forwards, the entire
quadrocopterwillhoverforwards.Ifyoumovethehand-held
transmitter backwards, the quadrocopter will hover back-
wards.

d) Roll function
"Roll" denotes the movement around the longitudinal axis,
similar to rolling a ball sideways (or the sideways movement
a crab). As a result, by lifting one side the quadrocopter
moves to the side, regardless of the forward direction.
Ifyoumovethehand-heldtransmittertotheleft,thewhole
quadrocopterwillhovertotheleft.Ifyoumovethehand-held
transmitter to the right, the whole quadrocopter will hover to
the right.
e) Flight Mode
Withthequadrocopteryoucanchoosebetweenthreedifferentightmodes,dependingonyourexistingightexperi-
ence.
Youcanchangetheightmodebybrieypressingthe"ightmode"button(gure4,item3)onthetransmitter.
Inbeginnermode,thecontrolcommandsarelimitedinawaythatletsyoulearntoythequadrocopterveryquickly
andeasily.Thisightmodeisrecommendedforpilotswhohaveverylittleornoexperienceyingwithaquadrocopter.
 Beginnermodeisthedefaultcongurationeverytimeyouturnonthetransmitter.
Advanced mode is recommended for pilots who have already gained some experience with other quadrocopter mod-
els.Inthismode,thequadrocopterissignicantlymoreagileinitscontrolbehaviourthaninbeginnermode.Toacti-
vatethismode,brieypressthe"ightmode"buttononthetransmitter(gure4,item3)untilyouhearadoublebeep.
Ifyoupresstheightmodebuttonagain,youwillhearatriplebeepanditwillswitchintoexpertmode.Thereisno
limit to the control functions here. This setting is recommended for pilots who already have a great deal of experience
in controlling quadrocopters.
Bypressingthe"ightmode"buttononcemore,beginnermodeisactivatedagain.Thisisindicatedbyasinglebeep.

12. The rst start
a) Starting
The operation and handling of remote controlled model aircraft must be learned! If you have never before
operated a model of this kind, take extra care at the start and get used to the reactions of the model to the
remotecontrolcommandsrst.Bepatient!FollowtheinstructionsinChapter11.
Do not take any risks when using the product! Always use the model responsibly, otherwise you may
endanger yourself and your surroundings.
Fullychargetherechargeableightbatteryifyouhavenotalreadydoneso.
Switchonthequadrocopter(buttoninthemiddleofthebody).TheLEDsinthebodystarttoasheverysecond.The
(red) LEDs point backwards (to you) and mean "back".
Placethemodelonasmooth,atsurface(e.g.astoneoor).Acarpetislesssuitablehere,sincethequadrocopter
could easily get caught in the carpet.
Switchonthehand-heldtransmitterbypressingtheon/offswitch.Thetransmitterindicatesthisbyabeep.Thecontrol
LEDinthetransmitterashes.
Pushthecontrolleverofthehand-heldtransmitter(gure4,item4)forwardsandthenbackwards.ThecontrolLED
in the transmitter as well as the LEDs in the quadrocopter now light up permanently. Return the control lever to the
neutral position (centre position).
Thequadrocopterisnowboundwiththetransmitterandreadyfortakeoff.Holdthehand-heldtransmitterhorizontally
(seegure5andtheinstructionsinthischapter).
Starttherotorsbypushingdownthe"startrotors/automaticlanding"(gure4,item4)buttonfromabove(pushthe
controlleverofthehand-heldtransmitterdownwards).Startthemotors
Now increase the quadrocopter rotor speed by slowly pushing the control lever forward until the quadrocopter as-
cends and then hovers in front of you at a height of approx. 1.5 metres.
Avoid any fast or big control movements. When steering, observe whether and, if applicable, in which
direction the quadrocopter moves with the "roll" (sideways) or "nod" (forwards or backwards) functions.
Inthiscase,steercarefullyintheoppositedirectionofthedriftbytiltingthehand-heldtransmitterinthe
appropriate direction (also see chapter 11).
To land the quadrocopter again, pull the control lever back slowly at a suitable landing spot until the quadrocopter
dropstotheground.Asomewhathardlandingonthegroundisnotaproblemandshouldnotbecorrectedwithjerky
throttle movements.
Ifyouwanttoturnofftherotorsagain,pullandholdthecontrollever(gure4,item4)backforabouttwosecondsuntil
therotorshavestopped.Alternatively,pressthe“Stoprotorsimmediatelybutton(gure4,item8).
Try to land as vertically as possible ("helicopter landing"). Avoid landing at high horizontal speeds ("airplane landing").
If not already done, switch off the motors after landing.
Practicethisstart-upprocedureafewtimestogetafeelforthequadrocopter.Onceyouarereasonablycondent,
youcanstartcontrollingtheightdirectionwiththeyaw,nod,androllfunctions(seenotesinchapter11).Alwayssteer
slowlyandcarefullyandpracticetheprocedurealittlebeforetryinganewightmanoeuvre.Therstfewightsshould
last no longer than 30 to 60 seconds each.
