They contain important information on setting up and using the product. Do not give this product to a third party without the operating instructions.
3. Intended use The "Folding Drone GPS RtF" electric quadcopter is an electrically driven helicopter-like model that is controlled using the wireless remote control included. The quadcopter is designed solely for private use within the domain of model construction with the associated operating times. It is not suitable for other purposes. Using this product for any purposes other than those described above may damage the product and result in a short circuit, fire, electric shock or other hazards.
5. Product description The "Folding Drone GPS RtF" electric quadcopter is a pre-assembled helicopter-like model aircraft with four rotors and a built-in camera. Quadcopters are already used professionally to complete a wide range of tasks. The flight attitude and altitude of the quadcopter are stabilised by state-of-the-art microprocessor-controlled electronics with position control and acceleration sensors, as well as a GPS function.
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. a broken rotor or chassis components) are not covered by the guarantee/warranty.
b) Before first use • The operation and handling of remote controlled quadcopters 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 there are no other models operating on the same frequency (2.4 GHz) within range of the remote control. Always check whether there are any other 2.4 GHz remote control systems that may interfere with the model.
• In the event of a crash, switch off the rotor motors immediately. Rotating rotors may be damaged if they come into contact with obstacles or in the event of an impact. Check the rotors for any signs of cracks or damage before flying the model again! • To avoid damaging the model due to a crash caused by an undervoltage/total discharging of the rechargeable battery, monitor the undervoltage indicators during the flight.
7. Battery information 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.
• When charging, place the charger and rechargeable flight battery on a non-flammable, heat-resistant surface (such as a stone tile). Keep the charger and battery away from flammable objects. Leave enough space between the charger and the 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.
• 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. • When charging a rechargeable lithium battery with more than one cell, be sure to use a so-called "balancer" (integrated in the included charger).
8. Preparations for flying a) Inserting batteries into the remote control Remove the battery compartment cover on the back of the remote control. To do this, you must first remove the cover screw and then push the lever in the direction of the arrow. Only then can the battery compartment lid can be lifted off. Insert four AA/mignon batteries, observing the correct polarity. Observe the polarity markings in the battery compartment. Then replace the battery compartment cover and secure it with the screw.
b) Charging the quadcopter rechargeable battery To power the included USB charger, use a suitable USB power adapter or USB cigarette lighter adapter (not included) with an output current of at least 1000 mA. It is not recommended to use a USB port on a computer or USB hub with its own power supply, as the charger's power requirements of approx. 1000 mA exceed the possible output current of a USB port.
c) Final assembly The model is pre-assembled and ready for use. 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. The rotors can be folded back into their initial position for transport or storage.

10. Safety features The "Folding Drone GPS RtF" electric quadcopter is equipped with a number of transmitter and model safety features designed to protect the model aircraft from damage and to minimise possible damage. The protection mechanisms are recognisable by a LED indicator (model aircraft) or an optical and acoustic warning signal (transmitter). a) Transmitter The state of the batteries is constantly checked when the transmitter is in operation.
11. Before first use 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. Directions are given from the perspective of a "virtual" pilot. The two green LEDs on the body of the model serve as direction indicators and mean "forward". This chapter explains the basics about flight operation. For proper flight operation, please observe the instructions in the following chapters.
b) Yaw function "Yaw" denotes the rotation of the quadcopter 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 quadcopter by speed differences from one individual rotor to another. If you move the control lever (Figure 4, no. 6) to the left, the quadcopter will turn to the left. If you move the control lever to the right, the quadcopter 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, lifting one side the quadcopter moves it to the side, regardless of the forward direction. If you move the right joystick (Figure 4, no. 13) to the left, the quadcopter will hover to the left. If you move the joystick to the right, the quadcopter will hover to the right.
12. First take-off a) Starting the quadcopter 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! Refer to the instructions in section 11. Do not take any risks when using the product! Always use the model responsibly, otherwise you may endanger yourself and your surroundings.
• Lift the model horizontally off the ground and turn it counter-clockwise three times around its own axis (see Figure 9, no. A). Immediately afterwards, hold the quadcopter upright (see Figure 9, no. B; with the camera facing upwards) and turn the model counter-clockwise three times around its own axis. Then place the quadcopter on a flat surface again. Figure 9 • If the LEDs on the model flash at a slow rate in a few more seconds, the calibration has been successful.
• Another option is to use the "Return and landing at the starting point" function. If you use the button (Figure 4, no. 4) provided on the transmitter, the model will automatically return to the starting point and land there. There may be very small deviations of 1 – 2 metres. If you select this function, the model will first ascend to a safe altitude, return straight to the starting point, land there and finally turn off the rotors.
b) Calibrating the quadcopter If the model can no longer hover on the spot (e.g. after a crash), the sensors must be recalibrated. Place the quadcopter on a level surface. Now press and hold down the "Calibrate" button on the transmitter (Figure 4, no. 8) for approx. three seconds. The LEDs on the model will flash very quickly. The LEDs will stay solid when calibration is complete. c) Headless mode The headless mode is a relative control mode, i.e.
13. FPV mode a) General information The quadcopter is standardly equipped with a camera that wirelessly transmits a live video signal to a suitable smartphone (not included). Pictures and videos are taken using an app installed on your smartphone. Pictures or videos can be stored and edited on your smartphone. In addition, the so-called "FPV operation" (FPV = "First Person View" = video image flying) is possible thanks to the live transmission.
b) Downloading the app A smartphone app is required to use FPV mode. The only costs incurred will be the normal costs incurred through downloading. The app itself is free. Scan one of the QR codes shown below depending on the operating system of your smartphone. After scanning the QR code, you will be automatically re-directed to the download page for the current version of the app.
d) Basic app functions The home page of the app is shown in Figure 15. The "Start" button opens the user interface shown in Figure 16.
The icons shown in the upper row (see Figure 16) have the following functions: 1 Exit screen 2 Indicators of altitude, distance, speed, position and controls 3 Indicator of the remaining capacity of the quadcopter rechargeable battery (only displayed when the smartphone is paired with the model) 4 Indicator of the video signal received from the quadcopter 5 Display of the current location via Google Maps 6 Cogwheel (show and hide icons for "Joystick, Param, Map and Other"; see also the following infor
If the cogwheel (Figure 16, no.
e) Flight with remote control in FPV operation Start and operate the model, as described in detail in chapters 11 and 12. You can now view the flight route on the screen of your smartphone. For the first test flights, it is advisable that the flight area is free of obstacles and that the flight operation is monitored by a co-pilot. In FPV operation, the co-pilot can keep you updated on the current flight situation and assist you with orientation.
g) "Follow me" mode When operating the model with the hand-held transmitter in FPV operation, you can also use the "Follow me" mode. If you enable this function, the model will follow the pilot at a defined distance. Adjust the desired distance and flight altitude at which the model should follow the pilot. Now select the corresponding symbol on the screen of your smartphone (Figure 16, no. 11, function type selection) to enable the "Follow me" mode. A submenu will open.
14. Controlling the quadcopter with your smartphone The quadcopter can also be operated solely with a smartphone as well as the transmitter included. There are two options for this shown below. To ensure an interference-free transmission of control and video signals, there should not be other transmitters in the model’s 2.4 GHz transmission range. The smartphone's "Bluetooth®" function must be disabled.
To control the quadcopter with your smartphone and in-app controls, follow the steps below: • Switch the quadcopter on. The LEDs flash The model now emits a WiFi transmission signal. • Switch on your smartphone. Under "Settings/WiFi", connect the "WIFI-720-GPS-xxxxx" signal to your smartphone. • Start the app for the quadcopter on your smartphone. • In the app, select the "START" button. The app controls and the video image of the model's built-in camera will appear on the display (see also Figure 16).
15. Other functions of the app a) Core Functions Indicators of altitude, distance, speed, position with GPS coordinates and values of the controls are shown in Figure 16, no. 2. In Figure 16, no. 3, you can see the remaining capacity of the quadcopter rechargeable battery as a percentage. A fully charged rechargeable battery is displayed with 100%. This value decreases during flight operation. For safety reasons, the model automatically initiates a landing process below a certain percentage value.
b) Cogwheel icon functions In Figure 16, no. 6, you will see a cogwheel icon. Selecting this icon opens a sub-menu with "Joystick, Param, Map and Other" functions (see Figure 17). Under "Joystick" (Figure 17, no. 7), you can make the following settings for flight operation: Figure 20a "Joystick mode": Selection of Mode 1 and Mode 2 (factory setting). In Mode 2, the altitude and yaw control functions are performed with the left-hand control; pitch and roll are performed with the right-hand control.
If you continue to scroll up the display, other setting options will be displayed: Figure 20b "Speed": Here you can set the control compliance of the model. Analogous to the information in chapter 11. e), here you can choose between the beginner and advanced mode by tapping. "Calibrate accelerometer": This function is used to calibrate the sensors (gyros). Refer to the instructions in section 12. "Calibrate magnetometer": This function is used to calibrate the compass.
d) Features under "Map" Figure 22 "Aircraft display map center": Specify here if the model icon (dot) should be always in the middle of the map ("YES") or moving on the map ("NO"). "Map coordinates auto calibrate (china)": This function is not available in this model. The factory setting should not be changed. "Map type": Here you can select displays and maps for GPS operation. Three different display types are available.
e) Features under "Other" Figure 23 "Real-time preview": For flight operation, you can choose between a low video resolution (480p = standard) and a high video resolution (720p). "Camera inverse": Enable this option to rotate the video image by 180°. f) Controlling with the position sensors of a smartphone Modern smartphones are equipped with built-in position sensors that always rotate the display according to the location of the device so that you can read or recognise the content.
16. Maintenance, servicing and repairs a) Regular cleaning The quadcopter is a very simply constructed aircraft . There are no mechanical parts that require lubrication or other maintenance. Nevertheless, you should clean any dirt (woollen threads, hair, dust, etc.) off the quadcopter after each flight. Clean the exterior of the model and the remote control with a soft, dry cloth or brush. Never use abrasive cleaning agents or chemical solutions, as these may damage the surface of the housing.
