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.
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.
• 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.
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.
• 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.
• 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.
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).
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.

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.
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.
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.
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.
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.
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.
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.
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).
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.
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 select "CONNECT" (B), the user interface shown in figure 14 opens. 1 2 3 4 5 6 7 8 9 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.
If the gear icon (see figure 15, item 9) is activated, the following icons will also be displayed: 9 20 21 22 23 Figure 15 20 "Rev": Rotate camera image by 180° 21 "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
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. 18 6 8 10 12 11 13 16 19 14 17 15 Figure 16 The icons that now appear allow you to control the model with the app.
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.
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.
Select the icon shown in figure 16, item 10. The rotors will start. The two controls (dots, see figure 16, item 12 + 13) 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.
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.
If the "gear" symbol (figure 14, item 9) is tapped, more icons to operate the model appear. With "REV" (figure 15, item 20) you can invert the video feed by 180°. Everything will be upside down. If you select "VR" (figure 15, item 21), it activates a 3D-like function. Here, the live view of the camera is split into two layers on the smartphone's screen. Together with virtual reality glasses (”VR glasses”, not included, must be purchased separately) FPV operation in 3D (i.e.
15. Maintenance, Servicing and Repair a) Regular Cleaning The "Gravity FPV" quadrocopter is a very simple model aircraft. There are no mechanical parts that require lubrication or other maintenance.
