5.2 Charging the Drone Battery

Connect the drone battery to the USB charging cable and plug it into a USB power source. The charging time is approximately 90 minutes. The indicator light will show charging status (refer to charger for specific light behavior).

5.3 App Installation (for FPV and Smart Control)

To use WiFi FPV and advanced control features, download the dedicated app on your smartphone. Search for the app name (usually indicated on the packaging or a QR code) in your device's app store (Google Play Store for Android, Apple App Store for iOS). Alternatively, scan the QR code provided in the product packaging or on the product page.

5.4 Pairing the Drone and Remote

1. Place the drone on a flat surface.
2. Turn on the drone's power switch. The indicator lights will flash.
3. Turn on the remote controller.
4. Push the left throttle stick all the way up, then all the way down. The drone lights will stop flashing, indicating successful pairing.

5.5 Calibration

After pairing, perform a gyroscope calibration. Place the drone on a flat surface. Move both control sticks to the bottom-right corner simultaneously until the drone lights flash rapidly and then become solid. This indicates successful calibration.

6. Operating Instructions

6.1 Basic Flight Controls (Left-Hand Throttle)

• Throttle (Left Stick Up/Down): Ascend/Descend.
• Yaw (Left Stick Left/Right): Rotate drone left/right.
• Forward/Backward (Right Stick Up/Down): Move drone forward/backward.
• Left/Right Sideways Flight (Right Stick Left/Right): Move drone left/right sideways.

6.2 One-Key Operations

Figure 6: One-touch takeoff, landing, and return functions, simplifying flight for novices.

• One-Key Takeoff: Press the one-key takeoff button (refer to controller diagram) to automatically launch the drone and hover at a certain altitude.
• One-Key Landing: Press the one-key landing button to automatically land the drone.
• One-Key Return: Press the one-key return button to make the drone fly back towards the remote controller.

6.3 Altitude Hold Mode

Figure 7: Altitude Hold feature allows the drone to hover automatically and stably when the remote control is released.

The drone features air pressure altitude hold, allowing it to maintain a stable height automatically, making it easier to control and capture steady photos/videos.

6.4 Headless Mode

Figure 8: Headless Mode simplifies control by orienting the drone's movement relative to the pilot, regardless of the drone's actual front direction.

In headless mode, there is no need to distinguish the real-time flight direction of the drone. The flight is centered on the direction of the remote control, making control simpler, especially for beginners.

6.5 3D Flip / 360° Stunt Roll

Figure 9: The 3D flip allows the drone to flip in 4 directions: forwards, backwards, left, and right at the touch of a button.

Figure 10: Rollover stunts in the air can be easily achieved with just one button.

Press the 3D Flip button on the remote controller and then move the right control stick in the desired direction (forward, backward, left, or right) to perform a 360-degree stunt roll.

6.6 Speed Control

Figure 11: Double gear speed switch allows you to choose the speed that suits your flying skill level.

The drone offers a double gear speed switch. Use the speed control button on the remote to cycle through different speed modes (e.g., low, medium, high) to match your flying skill level and environment.

6.7 HD Camera & FPV
