User Manual for Holy Stone HS440G RC Quadcopter

Quick guide from the manual

This manual provides instructions for operating the Holy Stone HS440G drone. Key operational requirements include ensuring a strong GPS signal (7+ satellites) for RTH functions, calibrating the compass before the first flight, and maintaining a clear line of sight. Always operate in open areas away from obstacles, crowds, and high-voltage power lines.

Drone Functions

The drone features three types of Return to Home (RTH) functions:

• Smart RTH: Triggered by pressing the RTH button on the transmitter when the GPS signal is strong.
• Failsafe RTH: Automatically activated if the connection between the transmitter and drone is lost for more than 6 seconds.
• Low Voltage RTH: Automatically triggered when the drone battery is low. The drone will return and hover at 49ft above the Home Point.

Stabilization Functions

The drone utilizes two primary stabilization systems:

• Optical Flow Positioning: Uses a camera module to acquire position information. Optimal usage height is 1.6-9.8 ft. Avoid flying over transparent, reflective, or monochrome surfaces.
• Altitude-Hold Function: Maintains the drone's altitude after releasing the left joystick.

App Interface

The app provides real-time flight data and control options. Key features include:

• System Status: Displays flight status and warnings.
• Flight Settings: Access to modify height, distance, and return altitude.
• Map View: Switch between camera view and map view.
• Flight Modes: Access to Circle Flight, Follow Me, and Headless Mode.

Flight Modes

• Beginner Mode: Limits flight distance (0-98 ft) and height (0-98 ft).
• Circle Flight: The drone records its current position and circles around it clockwise.
• Follow Me: The drone tracks the GPS signal of your mobile phone. Ensure the flight range is within 16-98 ft.
• Headless Mode: The drone's orientation is fixed to the direction it faced during takeoff, making it easier for beginners to control.
• Tap Fly: Allows you to draw a path on the map for the drone to follow.

Camera and Video

To capture media, use the app interface to switch between photo and video modes. Photos and videos are saved to the app album and the TF card (if inserted). Ensure the TF card is Class 10 or above with a capacity up to 64 GB.

Status Indicators

The drone uses LED lights to communicate status:

• Fast flashing yellow: Unsuccessful pairing.
• Front arm light steady red, rear arm light steady yellow: Searching for GPS/Exited GPS mode.
• Front arm light steady red, rear arm light steady green: GPS signal successful.
• Front and rear arm lights alternately flashing yellow: Compass calibration.

Specifications

Key technical parameters for the HS440G:

Troubleshooting

If you encounter issues, check the following:

• Drone not connecting/No live feed: Ensure only one device is connected to the Wi-Fi. Restart the drone/cellphone.
• Instable flight: Fly in open spaces, recalibrate the compass, or replace propellers.
• No map in app: Pre-load the map by connecting to the internet before flight.
• Drone cannot take off: Ensure the drone and transmitter are paired, battery is full, and compass is calibrated.
