4.2 Propeller Installation
Ensure propellers are correctly installed. Each propeller is marked with 'A' or 'B'. Match the propeller to the corresponding motor arm. Incorrect installation will prevent proper flight.
4.3 App Download and Connection
- Scan the QR code in the APP Manual or search for the designated app (e.g., 'S2S FPV') in your smartphone's app store (compatible with Android 5.0+ and iOS 9.0+).
- Turn on the drone and the remote control.
- On your smartphone, go to Wi-Fi settings and connect to the drone's Wi-Fi network (usually named 'FLOW_RC_XXXXXX').
- Open the drone app. The live video feed from the drone's camera should appear.

5. Operating Instructions
5.1 Basic Flight Operations
- Power On: Place the drone on a flat surface. Press and hold the power button on the drone until the indicator lights turn on. Turn on the remote control.
- Pairing: Push the left joystick (throttle) up and then down. The drone's lights will stop flashing, indicating successful pairing.
- One-Key Takeoff: Press the one-key takeoff/landing button on the remote control. The drone will automatically ascend and hover at a stable altitude.
- Controlling Flight: Use the left joystick for altitude and rotation. Use the right joystick for forward, backward, left, and right movements.
- One-Key Landing: Press the one-key takeoff/landing button again. The drone will automatically descend and land gently.
5.2 Advanced Features
Video: Overview of the GoolRC S2S Drone's key features and flight modes.
- Headless Mode: Press the Headless Mode button. In this mode, the drone's orientation is relative to the pilot, regardless of the drone's front direction. This simplifies control for beginners.
- Altitude Hold: The drone maintains a stable altitude automatically, allowing for easier control and clearer aerial photography.
- Obstacle Avoidance: Activate the obstacle avoidance feature using the dedicated button on the remote. The drone will automatically detect and avoid obstacles in its path, enhancing flight safety.

6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the drone and remote control. Do not use harsh chemicals or solvents.
- Propellers: Regularly inspect propellers for damage (cracks, bends). Replace damaged propellers immediately using the provided screwdriver and spare parts.
- Battery Care: Store batteries in a cool, dry place. Do not overcharge or over-discharge. If storing for extended periods, charge to approximately 50%.
- Storage: When not in use, fold the drone arms and store all components in the carrying case to protect them from dust and damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Drone does not respond to remote. | Not paired; low battery; out of range. | Re-pair drone and remote; charge batteries; ensure drone is within operating range. |
| Drone drifts during flight. | Not calibrated; uneven surface at takeoff; wind interference. | Calibrate the drone on a flat surface; fly in calm conditions. |
