5 3. Intended use The "Gravity FPV" quadrocopter is an electrically driven helicopter-like model that is controlled wirelessly via the included radio remote control system. The quadrocopter is designed solely for private use within the domain of model construction with the associated operating times. This system is not suitable for other types of use. Use other than that described above can lead to damage to the product and may involve additional risks such as short circuits, fire, electric shocks, etc. Please observe the safety instructions at all times! The product must not become damp or wet. This product is not a toy and must be kept out of the reach of children under 14 years of age. Always follow the safety information in these operating instructions. It contains important information on how to handle the product safely. You are responsible for the safe operation of this model! 4. Product description The "Gravity FPV" quadrocopter is a pre-assembled helicopter-like model aircraft with four rotors and a built-in camera. Professionally, such flying 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 = first person view = flying 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 flight operation. The novel controls and electronic self-stabilisation result in excellent flight 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 flight 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 the included USB charger. To operate the transmitter, you require 2 AAA/Micro type batteries (e.g. Conrad Item No , please order 2x). 5

7 6. Safety information Damage caused due to failure to observe these instructions will void the warranty. We shall not be liable for any consequential damage. We shall not be liable for damage to property or personal injury caused by incorrect handling or failure to observe the safety information! Such cases will void the warranty/guarantee. Normal wear and tear and accidents or damage caused by a crash (e.g. broken rotor blades or chassis parts) are excluded from the guarantee and warrantee. 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. Read this section very carefully before using the product. a) General information Caution, safety hazard! This model has the potential to cause damage to property and/or individuals. Ensure that you are sufficiently insured, e.g. by taking out private liability insurance. If you already have such a policy, check with your insurance company that use of this model is covered by the policy. Important: In some countries, you are required by law to have insurance for all model aircraft! You should also check the local statutory regulations for using model aircraft. In Germany, for example, the regulations for operators of model aircraft of all types are established in the German Air Traffic Ordinance. Any breaches of the statutory regulations established could lead to severe penalties as well as restrictions to your insurance cover. The unauthorised reconstruction and/or modification of the product is prohibited for safety and approval reasons. This product is not a toy and must be kept out of the reach of children under 14 years of age. The product must not become damp or wet. Do not leave packaging material unattended, as it may become a dangerous toy for children. If you do not yet have sufficient knowledge of how to handle remote-controlled models, please seek the advice of an experienced model making enthusiast or a model making club. If you have any questions that are not answered by these operating instructions, please contact us (see section 1 for contact information) or an experienced technician. 7

8 b) Before first use The operation and handling of remote controlled quadrocopters must be learned! If you have never operated a model of this kind, start with particular care and get used to the reactions of the model to the remote control commands first. Be patient! Ensure that no other models are being operated on the same 2.4 GHz band (transmitter frequency) within the range of the remote control. Always ensure that 2.4 GHz transmitters operated at the same time do not interfere with your model. Conduct regular checks to verify that your model and remote control are safe to use. Pay attention to visible damage, such as a damaged mechanism (e.g. rotors). All movable parts on the model must be running smoothly; however, there must be no play in the bearing. The rechargeable flight battery must be charged in accordance with the instructions in this operating manual. Check before each operation that the rotors are correctly fitted and securely fastened. Make sure that there is sufficient remaining capacity (battery checker) for the batteries inserted in the transmitter. If the batteries are empty, replace all of the batteries together. Never replace individual batteries. When the rotors are running, ensure that there are no objects or body parts in the rotors turning range or intake area. c) During use Do not take any risks when using the model! Always use the model responsibly, otherwise you may endanger yourself and your surroundings. Improper use can cause serious injury and damage to property! Ensure that you stay a safe distance away from people, animals and objects. Select an appropriate site for operation of your model. You should also check the local statutory regulations on the use of model aircraft. Fly your model only if your ability to respond is unrestricted. Fatigue, alcohol and medication can affect your ability to respond. Do not direct your model towards spectators or towards yourself. The motor, electronics and rechargeable flight battery can heat up when operating the model. For this reason, take a break of 5 to 10 minutes before recharging the flight battery. Always leave the remote control turned on when the model is in use. After landing, always flick the on/ off switch on the quadrocopter to the "off" position ("OFF"). Only then can the remote control transmitter be turned off. In case of a fault or a malfunction, establish the cause of the problem before using the model again. Do not expose the model or the remote control to direct sunlight or excessive heat for prolonged periods. In the event of a heavy crash (e.g. from a high altitude), the electronic gyro sensors can be damaged. Therefore, the model must be tested for full functionality before flying again! 8

9 In the event of a crash, you must immediately switch off the rotor motors. Rotating rotors may be damaged if they come into contact with obstructions or in the event of impacts. Before flying again, they must be checked for possible cracks or breakages! To avoid damaging the model in a crash caused by undervoltage or by a deep discharge of the battery, we recommend observing the undervoltage light signals at all times when flying the model. Pay attention to the maximum ranges according to the technical data in these operating instructions. If the model flies out of range, it will fly unchecked until it crashes! This will void the warranty/guarantee. 9

10 7. Information relevant to (rechargeable) batteries Batteries present numerous safety hazards. Compared with conventional NiMH rechargeable batteries, 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 fire 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 immediate medical advice if a battery is swallowed. Batteries/rechargeable batteries must never be short-circuited, taken apart or thrown into fire. 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 fire 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 fire 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 flight battery to high/low temperatures or direct sunlight. Batteries must not become damp or wet. The same applies to the charger and the quadrocopter/rechargeable flight 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. 10

11 Place the charger and the quadrocopter/rechargeable flight battery onto a non-flammable, heat-resistant surface (e.g. stone tiles). Keep the charger and battery away from flammable objects. Leave enough distance between the charger and the quadrocopter/rechargeable flight battery. Do not charge batteries when they are still hot (e.g. due to a high discharge current in the model). Allow the rechargeable flight battery to cool down to room temperature before charging it. As the charger as well as the rechargeable flight battery heat up during the charging procedure, it is necessary to ensure sufficient ventilation. Never cover the charger and the rechargeable flight 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 fire or explosion. If the rechargeable flight 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 fire (e.g. outdoors). Disconnect the rechargeable flight battery from the charger when the battery is fully charged. Never damage the casing of a rechargeable battery. Never charge damaged, leaking or misshapen batteries. This may cause a fire 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 significantly higher capacity than NiMH and NiCd batteries 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 batteries and explains how these hazards can be avoided to ensure a long lifespan. The casing of many lithium batteries is made of a thick film, 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 fire or explosion! The rechargeable flight battery can either be charged separately or inside the quadrocopter. Since the rechargeable flight battery is screwed into the quadrocopter, we recommend that you charge the rechargeable flight battery inside the quadrocopter. This way it will not need to be unnecessarily dismantled. Ensure that a lithium rechargeable battery does not overheat during use, recharging, discharging, transport or storage. Do not place the rechargeable flight battery (or the quadrocopter with the rechargeable flight battery inside) near heat sources and keep it away from direct sunlight. This may cause the battery to overheat, which can cause a fire or explosion! The temperature of the rechargeable battery must never exceed +60 C. 11

12 If the rechargeable battery is damaged or the outer casing is swollen (e.g. due to a crash causing damage to the quadrocopter), do not recharge it. This may cause a fire or explosion! Never store a damaged rechargeable flight battery in an apartment or in a house/garage. Damaged or swollen lithium batteries may catch fire. Always use a compatible charger to charge lithium batteries and ensure that the charging specifications are correct. Do not use NiCd, NiMH or lead-acid battery chargers, as these may cause a fire or explosion! Always select the correct charging specifications 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 instructions). 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 fire 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. 12

13 8. Preparation for takeoff a) Inserting batteries into the transmitter Remove the battery compartment cover on the rear side of the transmitter. 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). Observe 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 significantly longer. We recommend using high-quality alkaline batteries. Figure 1 b) Charge flight 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 charging. For flight operation, the rechargeable battery must be inserted into the battery compartment as shown in figure 2 and secured against loosening with a screw (A). To charge the rechargeable battery, it must not be removed; the battery 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 flight 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 Figure 2 13

14 c) Final assembly The model is delivered ready to fly. It comes with retractable rotor blades as a special feature. The packaged size is very small as a result, thus facilitating transport. For flight 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. Figure 3 14

16 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 protective 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 batteries drops below a certain value, the transmitter signals this with a permanent flashing of the LEDs on the controls (figure 4, item 2). In addition, a warning signal sounds ("di di"). In this case, you should immediately stop flying 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 flashing, 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 flight 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 flashing (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 flashing, only about 20 to 30 seconds flying time remains to autonomously fly the model back to the starting point and land it. When a certain voltage value of the rechargeable flight battery is reached, motor control is switched off by the transmitter and an automatic landing is initiated. This process can no longer be influenced by the transmitter. If the model is above a body of water, tree, house, road, people, animals, etc. and/or the model is flying 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 (figure 4, item 8). There is a separate icon in the app for this purpose. 16

17 11. Information about first 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 transmitter is not tilted forwards/backwards or to the left/right but lies horizontally in the hand (see picture 5). Otherwise, the model would hover in the direction in which the handheld transmitter points. a) Hover flight Figure 5 Hovering is defined as the flight 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 figure 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. 4 Figure 6 During a flight just above the ground as during takeoff, turbulence and air currents are created that can affect 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. 17

18 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 flight direction change. The movement occurs in the quadrocopter by speed differences from one individual rotor to another. If you move the control lever (figure 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. 4 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 flight 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 backwards. Figure 8 18

19 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 flight modes, depending on your existing flight experience. You can change the flight mode by briefly pressing the "flight mode" button (figure 4, item 3) on the transmitter. In beginner mode, the control commands are limited in a way that lets you learn to fly the quadrocopter very quickly and easily. This flight mode is recommended for pilots who have very little or no experience flying with a quadrocopter. Beginner mode is the default configuration every time you turn on the transmitter. Figure 9 Advanced mode is recommended for pilots who have already gained some experience with other quadrocopter models. In this mode, the quadrocopter is significantly more agile in its control behaviour than in beginner mode. To activate this mode, briefly press the "flight mode" button on the transmitter (figure 4, item 3) until you hear a double beep. If you press the flight 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 "flight mode" button once more, beginner mode is activated again. This is indicated by a single beep. 19

20 12. The first 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 first. 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 flight 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 flash every second. The (red) LEDs point backwards (to you) and mean "back". Place the model on a smooth, flat surface (e.g. a stone floor). 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 flashes. Push the control lever of the hand-held transmitter (figure 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 figure 5 and the instructions in this chapter). Start the rotors by pushing down the "start rotors/automatic landing" (figure 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 ascends 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 (figure 4, item 4) back for about two seconds until the rotors have stopped. Alternatively, press the Stop rotors immediately button (figure 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 confident, you can start controlling the flight 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 flight manoeuvre. The first few flights should last no longer than 30 to 60 seconds each. 20

21 If you are already familiar with the flight characteristics of the model, you can do further exercises. Here you should start with simple flight manoeuvres such as flying one metre forwards/backwards (nod function). Then practice hovering left/right (roll function). If you have enough practice at this, you can start attempting to fly in circles and figuresof-eight. If you want to stop the flight operation, the rotors must be switched off after landing. Then flick the on/off switch on the model into the "OFF" position (off = LEDs not lit). It is only afterwards that the transmitter must be turned off. b) Calibration If the model can no longer hovers on the spot (e.g. after a crash), the sensors must be recalibrated. To do this, place the ready-for-takeoff quadrocopter on an even, horizontal surface. Now press the "calibrate" button on the transmitter (figure 4, item 7). The LEDs on the model will flash very quickly. Calibration is complete when the LEDs on the model are solid again. If you have previously switched off the LEDs as described in chapter 12. f), you will know that the calibration process is finished when the LEDs stop flashing (LEDs are off). c) Starting rotors and landing with a button Attention! Starting the rotors requires a barrier-free takeoff site in all directions. This function can therefore only be used in large rooms/halls or outdoors. For safety reasons, people and objects must remain at least two metres away from the takeoff site. Automatic landing is a pre-programmed procedure. The prerequisite for a safe, automatic landing is that the model is in a stable flight state (hovering) before pressing the corresponding button on the transmitter, the altitude is ideally no more than 1.5 metres and the landing site is at least two metres away from any people or objects. Failure to ensure that this is the case may result in damage to the model or other nearby objects, as well as posing a risk of injury to any nearby people/animals! The rotors are activated using the button on the control lever (figure 4, item 4, push control lever like a button). The same button also initiates an automatic landing. To start the rotors, place the ready-for-takeoff quadrocopter on a flat surface at a sufficient distance from the pilot and any objects (see notes above). To start, press the "start rotors/automatic landing" button (figure 4, item 4) on the transmitter. The rotors start and the model takes off when you push the control lever forward. Now you can manoeuvre the flight through appropriate control movements on the transmitter. In order to land, find a suitable landing site (see notes above) and bring the model to a stable hover and to an altitude of ideally 1.5 metres max. Now press the "start rotors/automatic landing" button (figure 4, item 4, Press the Control Lever Like a Button) on the transmitter again. Immediately thereafter, the model will initiate the landing, reduce its altitude and switch off the rotors once it is on the ground. During the landing phase, you can still intervene to change the direction. 21

22 d) Flight movements After the model has been started and you are holding the hand-held transmitter horizontally, it will be in so-called hover mode. Gently push the control lever on the transmitter forward. This causes the model to ascend. If you put the control lever back into the centre position, the ascent stops. If you pull the control lever back, a descent is initiated. If the control lever is put back in the centre position, the descent stops. If you steer the control lever to the left, the model will turn around its vertical axis (yaw) to the left. If you steer towards the right, the quadrocopter turns right. Tilt the hand-held transmitter carefully forward (nod). The model is steered forward. If you tilt the hand-held transmitter backwards, the quadrocopter will be steered back. If the hand-held transmitter is tilted left, the model hovers to the left (roll). If the hand-held transmitter is tilted to the right, the quadrocopter hovers to the right. Please also observe the instructions in chapter 11 for controlling the model. e) Headless mode function Headless mode is a relative control mode, i.e. it does not matter which way the quadrocopter is facing; for example, it always flies to the right from the pilot perspective if it is steered to the right, regardless of whether the model faces back, left, forward or right. The Quadrocopter is thus always told in which direction it should fly via the position sensors for nod and roll, i.e. the direction of inclination of the hand-held transmitter. Important! The transmitter and the quadrocopter must be facing exactly the same way when activating headless mode! This function can therefore only be activated when the quadrocopter is not flying and stood firmly on the ground. The (red) LEDs point backwards. Failure to observe this will result in unexpected results, i.e. the quadrocopter does not go where it is directed. Headless mode is accomplished in the model by relatively simple means (e.g. no compass/gps support). Differences and inaccuracies when determining the flight path or the accuracy of the return are therefore normal. Since it is normally necessary to rethink the controls the moment a model aircraft flies towards you (you steer to the left, but the quadrocopter flies to the right), headless mode can help by doing this rethinking for you. No matter which way the quadrocopter is facing, this type of relative control can help beginners especially to get fast results. However, if you want to learn to fly correctly, you should not get too used to flying in headless mode and learn "normal" steering. To activate headless mode, bind the transmitter and quadrocopter together (start-up preparation). The rotors are still switched off for the first activation. Place the ready-for-takeoff quadrocopter on the ground ensuring that the red LEDs line up with the transmitter. Now briefly press the button for headless mode (figure 4, item 5) until you hear a beep. The LEDs on the quadrocopter flash three times in quick succession, indicating that you are now in headless mode. The transmitter sends out a rhythmic beep when headless mode is activated. Start the quadrocopter. The flight movements of the model will (regardless of the angle of the quadrocopter to the pilot) always follow the control directions (inclination of the hand-held transmitter). If you steer forward, the quadrocopter will always move away from you. When steering to the right, the quadrocopter will always move to the right. To disable headless mode, press the headless mode button again (figure 4, item 5) until you hear a beep. The quadrocopter signals the deactivation of headless mode in that the LEDs in the model stop flashing. The rhythmic beep in the hand-held transmitter stops. 22

23 f) Switch LEDs on and off The LEDs in the model can be switched on and off from the hand-held transmitter at the push of a button. To do this, press the corresponding button on the transmitter (see figure 4, item 6). The LEDs cannot be controlled when using the app for operation. The quadrocopter constantly monitors the voltage of the inserted rechargeable flight 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 drops below a critical value over a certain period of time, this is indicated by the LEDs flashing. For safety reasons, this occurs regardless of whether the LEDs have been switched off. 23

24 13. FPV operation a) General information The quadrocopter is equipped as standard with a camera, which can transmit live video to a suitable smartphone (not included in delivery contents). Pictures and videos are taken using an app installed on your smartphone. Pictures or videos can be stored on your smartphone and can be processed from there. The live broadcast makes a so-called "FPV operation" (FPV = first person view) possible. The camera can be adjusted by hand about 90 in the banking angle before starting. Attention! Pure FPV operation increases the risk of accidents because you may not see obstacles, or may not see them in time, due to the restricted camera image. Therefore, as a general rule, an FPV operation must be monitored by a co-pilot who can warn of dangers in good time. It therefore requires a lot of practice to fly in FPV operation. During the learning phase in particular, ensure that the selected flight area is free of obstacles and far away from people, animals, buildings and roads. To ensure the interference-free transmission of video signals, there should be no other transmitters in the model's 2.4 GHz transmission range. The smartphone's "Bluetooth " function must be disabled. FPV operation is only possible if the model is operated using the controls on the smartphone. However, the camera image is severely limited by the controls in the display (icons) as well as by the fingers operating the controls. b) Loading the app For FPV operation, you must first install a special app on your smartphone. The only costs incurred will be the normal costs incurred through downloading. The app itself is free. Scan one of the following pictured QR codes depending on your smartphone s operating system (ios or Android). By scanning the QR code, you will be automatically re-directed to the current version of the app. Alternatively you can search for the "REELY" app in the "Google Play Store" (for Android devices) or in the "Apple Store" (for the ios devices) (see also figure 12). REELY Figure 12: App Figure 10: App for ios Figure 11: App for Android 24

25 c) Prepare model for takeoff Get your quadrocopter ready for takeoff by binding it with the active transmitter. The model now emits a signal (similar to a wireless router). Activate the "WiFi" function on your smartphone under Settings". Search for "REELY-xxxxx" (xxxxx = a number/ character combination) among the WLAN signals found for the "REELY" app. This WLAN is transmitted from the quadrocopter and must be connected to your smartphone. If you have successfully connected the signal to your smartphone, leave the settings and open the app on your smartphone. The model is now ready for takeoff and can be operated with the hand-held transmitter in "FPV mode" (using the video feed). The following instructions explain how you can take additional photos and videos in this mode. Chapter 14 explains how to control the model with your smartphone. d) Basic app features In figure 13 you can see the app s home page. There are two choices there: (A) "?" (question mark) = Help (B) "CONNECT" = start the app Figure 13 Below the "question mark" icon (A) you will find operating instructions in English, which can help you if the operating instructions are not available. You can leave this help screen by selecting the icon displayed in the top left corner. 25

26 If you select "CONNECT" (B), the user interface shown in figure 14 opens Figure 14 The icons shown in the upper row (1-9, see figure 14) have the following functions: 1 Exit screen content 2 Capture image with the quadrocopter camera 3 Capture video with the quadrocopter camera 4 View saved images or videos 5 Flight mode (30 % = beginner, 60 % = advanced, 100 % = expert, see also chapter 11. e) 6 Height control (model tries to keep the current altitude. This function is only available if the controls are displayed) 7 "Gravity Sensor Control" (model is controlled by the position sensors of the smartphone for the "nod" and "roll" functions; function only available if the controls are displayed) 8 "OFF"/"ON" (controls fade in/out for rotor start/landing, rotor emergency stop, motor speed, yaw, roll, nod, and trim controls) 9 Gear icon (display and hide VR operation and calibration icons - see the following information) 26

27 If the gear icon (see figure 15, item 9) is activated, the following icons will also be displayed: Figure "Rev": Rotate camera image by "VR": Settings for 3D live view (only possible with special VR glasses) 22 Headless mode (see chapter 12) 23 Calibration (Calibration of quadrocopter sensors; see chapter 12) 27

28 e) App controls In order to start the model with the app, you must first tap icon #8 ( OFF ). Once selected, the icon changes to "On" and the controls are displayed. Now select icon #6. More icons are displayed in the centre of the screen Figure 16 The icons that now appear allow you to control the model with the app. The icons have the following meanings: 10 Start rotors 11 Automatic landing (model drops to ground automatically and stops rotors after landing) 12 Control lever for "ascent/descent" and "yaw" 13 Control lever for "nod" and "roll" 14 Trimming element for "yaw" 15 Trimming element for "roll" 16 Trimming element for "nod" 17 Stop rotors immediately (e.g. after a crash) 18 Flip (activation of function, see chapter 14. c) 19 Flight route (shapes drawn on the display (e.g. a circle) or routes are flown by the quadrocopter automatically) Attention! For the automatic flight of a route, the model requires a barrier-free space in all directions. This function can therefore only be used in very large rooms/halls or outdoors. People and objects must be at least 10 metres away from the takeoff site. Failure to ensure that this is the case may result in damage to the model or other nearby objects, as well as posing a risk of injury to any nearby people/animals! 28

29 If the quadrocopter is ready for takeoff and the app on your smartphone is activated via "CONNECT", you will receive a live feed of the quadrocopter camera. You can thus start immediately and fly the quadrocopter using the camera feed in so-called FPV mode. The model is controlled by the handheld transmitter. If you want to control it with a smartphone, the hand-held transmitter must be switched off. In addition, you can use your smartphone display before or during operation of the quadrocopter to take a picture with the quadrocopter camera or start a video recording by tapping the appropriate icon (see figure 14, item 2 or 3). Continuous advance photos cannot be taken with the app. By tapping the appropriate icon (figure 14, item 2), the camera is activated. After releasing the icon, the image is taken. You can stop a video recording by tapping the appropriate icon (figure 14, icon 3) again. During video recording, a stopwatch for the recording time will be displayed. To end a video recording, simply tap the appropriate icon again. This ends the recording, hides the stopwatch and saves the recorded video. During a video recording, it is also possible to take pictures at the same time. 14. Operating quadrocopter using your smartphone The "Gravity FPV" quadrocopter can be controlled using only a smartphone instead of the included transmitter. There are two options for this shown below. To ensure an interference-free transmission of control and video signals, there should be no other transmitters in the model s 2.4 GHz transmission range nearby. The smartphone's "Bluetooth " function must be disabled. The model s reaction to control commands from the smartphone is a bit slower and (since it is unfamiliar) not as accurate as operation with the transmitter. Please ensure that the flight area is therefore barrier free. Be patient when controlling the model using a smartphone. a) Take/view pictures or videos The quadrocopter is equipped with a camera as standard. Pictures and videos can taken from the app installed on the smartphone. The pictures or videos are saved on your smartphone. If you have activated flight mode, you can view the pictures or videos taken directly on your smartphone. To do this, select the corresponding icon (figure 14, item 4) on the display. A new screen appears. Select either "pictures" or "video". Depending on the selection, another screen with the saved pictures or videos pops up, which can then be tapped to open for viewing. To delete the pictures or videos, select the appropriate file in your smartphone s memory. 29

30 b) Operation using the controls of your app After starting the app, various controls are shown on the smartphone screen in addition to the camera feed (see figure 16). In addition to the previously seen camera controls (see figure 14, items 2-4), after selecting the corresponding icon (figure 16, items 6 and 8), the controls for a remote control transmitter are also displayed. The left-hand control lever (figure 16, item 12) controls both the height and the rotation about its own vertical axis (yaw) in the same way as the remote control transmitter. Unlike with the hand-held transmitter and its position sensors, the right-hand control lever (figure 16, item 13) is used to control "nod" and "roll" (see figure 17). A forward manoeuvre with this control corresponds to a forward pitch and works in the same way as when the hand-held transmitter is titled forward. Pulling the control backwards is similar to tilting the hand-held transmitter backwards. Steering to the left is like tilting to the left with the hand-held transmitter. Figure 17 Figure 16 shows the corresponding trimming elements for "yaw" (item 14), "roll" (item 15) and nod" (item 16). For trimming, press the left/right arrow as required by "yaw" and "roll" or the up/down arrow for "nod" repeatedly, until the desired flight behaviour is set. If you want to operate the model with a smartphone and the controls available in the app, proceed as follows: Switch the quadrocopter on. The LEDs flash The model now emits a WiFi transmission signal. Switch on your smartphone. Under "settings/wifi", connect the "REELY" signal (REELY-xxxx) to your smartphone. Activate the "REELY" app for the quadrocopter on your smartphone. Select "CONNECT". The display shows the app controls (see also figure 14) and the video feed of the camera built into the model. Place the quadcopter onto an suitable starting point. Please also keep in mind all instructions from chapters 11 and 12. Select the icon shown in figure 14, item 8, followed by the icon in figure 14, item 6. All controls appear as "dots" and all other controls necessary for operation (see figure 16). Now the LEDs of the quadrocopter should light up permanently and thus indicate the successful "binding" of the model with the app on the smartphone. 30

31 Select the icon shown in figure 16, item 10. The rotors will start. The two controls (dots, see figure 16, item ) on the smartphone display represent the control pads of a remote control transmitter and can also be operated in such a way. Keep your smartphone in your hands. Touch each dot with one finger (preferably with your thumbs) and steer the model as explained in chapters 11 and 12. To start, move the left-hand control lever (figure 16, item 12) forward until the model lifts and hovers at a height of approx. 1.5 metres in front of you. If you want to land the model again, slowly move the left control lever (figure 16, item 12) backwards. Alternatively, you can initiate an automatic landing by selecting the icon in figure 16, item 11. c) Additional app controls In its default configuration (see figure 14, item 5), the app is set to approximately 30 % of the maximum possible control paths in the first stage. This corresponds to beginner mode (see chapter 11). The effect of the control functions is limited. If you tap the icon shown in figure 14, item 5 again, the controller is set to approx. 60 % of the control paths. This corresponds to advanced mode. The model reacts in a more agile way to control commands. If the icon is tapped again, the display changes to 100 %. Now there is no limitation of the control functions, which corresponds to expert mode. By tapping the icon again, the display returns to the first level (30 %). The model can do a flip (360 turn). To do this, ensure that the quadrocopter is sufficiently far away from the pilot and other obstacles and then bring it to a hover at least 3 metres from the ground. The flip function is activated by tapping the icon shown in figure 16, item 18. Now briefly push the right control lever in the direction in which you want the flip to occur. Examples: If you push the right control lever forward, the quadrocopter will flip forward. If you push the right control lever to the right, the quadcopter will flip right. After setting the flip direction on the smartphone, immediately return the right control lever to its neutral position. Attention! The flip function may only be used if the model is flown in a large hall/large room or outdoors, is in a stable flight state (hovering) before the appropriate button on the smartphone is tapped, the altitude is not less than 3 metres and the quadrocopter is at a distance of at least 5 metres from any people or objects. Failure to observe this may result in damage to the model or other material damage, as well as a risk of injury to nearby people/animals in the event of a collision or fall! If the model is already in "low batt mode" (LEDs on the quadrocopter are flashing), the flip function is disabled for safety reasons and is therefore unavailable. 31

32 The model can perform the flip function only in a single direction (only forwards or backwards, only left or right - i.e. only with the right control lever) and thus also requires clear control commands from the smartphone (right control lever forwards or backwards; right control lever left or right). For this reason, avoid disallowed control commands such as "right control lever forward + left lever pressed" when the flip function is active. This could cause uncontrolled flight conditions or a crash. After a flip has been performed, this feature is automatically disabled on the smartphone. If you want to perform another flip, the flip function on the smartphone must first be reactivated. The icon in figure 16, item 19 activates the "flight route" function. The left control lever remains visible and can be used for steering (high/low and yaw). The right-hand control lever is hidden. Here you can draw flight routes on the smartphone s display (see figure 18, e.g. a circle). The drawn route is then be flown by the model automatically. To do this, bring the model to a stable flight state and activate icon #19. Now draw a route on the display. After you have finished drawing the route (by lifting your finger off the smartphone s screen), the model will immediately fly the drawn route. 19 Attention! Figure 18 For the automatic flight of a route, the model requires a barrier-free space in all directions. This function can therefore only be used in very large rooms/halls or outdoors. People and objects must be at least 10 metres from the takeoff site. Failure to ensure that this is the case may result in damage to the model or other nearby objects, as well as posing a risk of injury to any nearby people/animals! Automatic flight is a pre-programmed procedure. The prerequisite for this is a stable flight state (hovering), an altitude ideally no higher than 1.5 metres and a route at least 10 metres away from any people or objects. 32
