Setup Guide

1. Charging the Batteries

Before first use, fully charge both modular batteries. Connect the USB charging cable to the battery and then to a USB power source (e.g., computer USB port, USB wall adapter). The indicator light on the charging cable will show charging status. Charging typically takes about 60-80 minutes per battery.

2. Installing Drone Batteries

Carefully insert a fully charged modular battery into the battery compartment at the bottom of the drone until it clicks into place. Ensure it is securely fastened.

3. Preparing the Remote Control

The remote control requires 3 AAA batteries (not included). Open the battery compartment on the back of the remote and insert the batteries, observing polarity. Close the compartment securely.

4. Pairing Drone and Remote

1. Place the drone on a flat, level surface.
2. Turn on the drone by pressing the power button. The drone's indicator lights will flash.
3. Turn on the remote control. The remote's indicator light will also flash.
4. Push the left joystick (throttle) all the way up, then pull it all the way down. The drone's lights will stop flashing and turn solid, indicating successful pairing.

Note: When using multiple drones simultaneously, power on and pair each drone and remote separately to prevent frequency interference.

5. App Installation (Optional for FPV)

To use the FPV camera and advanced features, download the Holy Stone app from your smartphone's app store. Connect your phone to the drone's Wi-Fi network (usually named "HolyStone-HS420-XXXX").

Maintenance

Propeller Replacement

If a propeller is damaged, it can be replaced using the provided propeller spanner and spare propellers. Ensure you match the new propeller to the correct motor arm (indicated by markings on the drone and propellers, typically A and B or different colors).

• Gently remove the damaged propeller using the spanner.
• Align the new propeller with the motor shaft and press down firmly until it is secure.

Battery Care

• Always use the original charging cable.
• Do not overcharge or over-discharge batteries.
• Store batteries in a cool, dry place away from direct sunlight and extreme temperatures.
• If not used for an extended period, charge batteries to about 50% capacity every three months.

General Cleaning

Wipe the drone with a clean, dry cloth after use. Avoid using water or harsh chemicals. Keep the camera lens clean for optimal image quality.

Troubleshooting

• Drone not responding to remote: Ensure both the drone and remote are powered on and correctly paired. Check remote control batteries.
• Drone unstable during flight: Perform a calibration. Ensure propellers are not damaged and are correctly installed. Check for strong air currents or wind.
• Poor camera feed/connection: Ensure your smartphone is connected to the drone's Wi-Fi network. Move closer to the drone to reduce interference.
• Short flight time: Ensure batteries are fully charged. Flight time can vary based on flight style (e.g., frequent stunts, high speed).
• Drone not taking off: Check if batteries are fully charged and properly installed. Ensure propellers are not obstructed.
