3. Setup and Assembly
3.1. Propeller Installation
Ensure correct propeller installation for safe flight. Propellers are labeled 'A' and 'B'. Match them to the corresponding motor arms.

Figure 3.1: Propeller Installation Diagram
Important: Make sure the exact installation is correct, otherwise normal flights will not be possible. Install propeller guards to protect motors from damage.
3.2. Battery Charging
- Remove the battery from the aircraft.
- Plug the battery into the USB charger.
- Plug the USB charger into a computer's USB port or a suitable USB power adapter. The glowing red light indicates charging.
- For the aircraft battery, a blinking indicator light means it is charging. A solid red light means it is fully charged.
- For the remote control, the charger light turns on when charging. Ensure the remote control is switched off during charging.
Note: Disconnect the charger once batteries are fully charged. Do not mix new and old batteries, or different types of batteries. Remove batteries for long-term storage.
3.3. App Download and Connection
Download the 'Fly Plus' app on your smartphone. The app is compatible with phones running iOS 10.0, Android 6.0, or higher. Refer to the 'anin-anleitung' (app instructions) section within the app for detailed connection steps.
4. Operating Instructions
4.1. Pairing and Calibration
- Ensure drone batteries are fully charged.
- Insert the charged batteries into the drone and power it on. The blue lights will flash and enter WM mode.
- Turn on the remote control. You will hear two 'di' beeps, and the drone's flashing lights will change, indicating successful pairing.
- Calibration: Place the aircraft horizontally on the ground, with the head (camera) facing forward. Push the left control stick down-left and the right control stick down-right simultaneously. Once you hear a 'drop' (beep), the aircraft's indicator lights will flash and then become solid, indicating successful calibration.
4.2. Takeoff and Landing
- Motor Arming: Push the throttle stick (left stick) up and then down to arm the motors.
- One-Key Takeoff: Place the aircraft on a horizontal surface. Press the 'one-key ascend' button on the remote control. The aircraft will automatically rise to a height of approximately 1.5 meters.
- One-Key Landing: When the aircraft is in the air, press the 'one-key descend' button (lower left corner of the remote control). The aircraft will automatically land on the ground.

4.3. Flight Controls
- Throttle (Up/Down): Left joystick, vertical movement.
- Yaw (Left/Right Swivel): Left joystick, horizontal movement.
- Pitch (Forward/Backward): Right joystick, vertical movement.
- Roll (Left/Right Strafe): Right joystick, horizontal movement.

4.4. Speed Adjustment
The remote control allows adjustment of flight speed. Push the left stick down to cycle through speed modes. Two 'di' beeps indicate medium speed, three 'di' beeps indicate fast speed. Another 'di' beep returns to slow speed.
4.5. Intelligent Flight Modes
- Intelligent Return: Features include One-click return, Low battery return, Lost contact return, and Ultra-distance return. The drone will automatically plan a return route.
- Omnidirectional Obstacle Avoidance: The drone is equipped with laser avoidance sensors for 360-degree all-round escort, automatically stopping and flying around obstacles.
- GPS Smart Follow: Multiple follow modes allow the drone to follow you wherever you go.
- Intelligent Surround: The drone can orbit a designated point.
- One-Click Remote Flight: Initiate complex flight paths with a single command.
- Waypoint Trajectory Flight: Plan a flight path on the app, and the drone will follow it automatically.
- 3D Flip: Fly the drone 2-3 meters high. On the remote control, press the right control stick (or designated button) three times ('di', 'di', 'di'). Then push the right joystick in the desired direction for the flip. 360-degree flips work better with full throttle. Avoid performing flips at low altitudes.
- Headless Mode: Once activated, the drone moves independently of its orientation, according to its original designated direction. The blue lights on the tail illuminate in headless mode.

4.6. Photo and Video Recording
The drone features an 8K HD camera with a three-axis mechanical self-stabilizing gimbal for clear and stable aerial footage. Use the dedicated buttons on the remote control to start/stop recording video or take photos.

5. Maintenance
- Battery Care: Always fully charge batteries before flight. Disconnect chargers once batteries are full. Remove batteries for long-term storage.
- Propeller Replacement: If propellers are damaged, replace them with new ones, ensuring correct 'A' and 'B' alignment.
- Cleaning: Keep the drone and remote control clean and free from dust and debris. Use a soft, dry cloth.
- Storage: Store the drone in its carrying case in a cool, dry place away from direct sunlight and extreme temperatures.

6. Troubleshooting
- Drone not responding/unstable flight: Ensure batteries are fully charged and correctly installed. Perform calibration as described in Section 4.1. Check propellers for damage and correct installation.
- Low Battery Warning: When all indicator lights flash and the remote control beeps 'di' 'di' 'di', the battery is low. Initiate an urgent return operation. Do not perform 360-degree flips when low battery warnings are active.
- Emergency Stop: In an emergency, press and hold the emergency stop button on the remote control for 2 seconds to force stop the drone. This operation is very useful in critical situations.
- Drifting during flight: Use the trimming function to correct drift. If the aircraft drifts, after five seconds, a 'di' beep will sound for trimming. Push the stick in the opposite direction to correct the drift.
- Ground Effect: Be aware that when the aircraft is approximately 30cm above the ground, it can become unstable due to ground effect. This is normal, but be cautious at low altitudes.

8. User Tips
- Always ensure the drone is calibrated correctly before each flight for optimal stability.
- Practice basic flight controls in an open, safe area before attempting advanced maneuvers or intelligent flight modes.
- Monitor battery levels closely and initiate return procedures when low battery warnings appear.
- When performing 3D flips, ensure sufficient altitude (2-3 meters) and full throttle for best results.
- Be mindful of ground effect when flying at very low altitudes (around 30cm), as it can affect drone stability.
