• One-Key Landing: Press the designated button to initiate an automatic landing sequence.
• Air Pressure Altitude Hold: The helicopter will maintain its current altitude automatically, allowing for easier control.
• Optical Flow Positioning: This function assists in maintaining position, especially useful in indoor environments with clear ground patterns.

7. Maintenance

7.1 General Care

• After each flight, inspect the helicopter for any visible damage, loose parts, or debris.
• Clean the helicopter with a soft, dry cloth. Avoid using water or solvents.
• Ensure all moving parts are free from obstructions.
• Store the helicopter and remote control in a safe, dry place away from direct sunlight and extreme temperatures.

7.2 Propeller Replacement

If a propeller blade is damaged, replace it immediately to ensure stable flight.

2. Gently remove the damaged propeller.
3. Install a new spare propeller, ensuring it is oriented correctly.
4. Secure the new propeller with the screw, but do not overtighten.

7.3 Battery Care

• Always use the original USB charger for the helicopter battery.
• Do not puncture, short-circuit, or disassemble the battery.
• If the battery becomes swollen or damaged, discontinue use immediately and dispose of it properly.
• Do not expose batteries to fire or extreme heat.

8. Troubleshooting

8.1 Helicopter Does Not Respond to Remote Control

• Ensure both the helicopter and remote control are powered on.
• Check if the remote control batteries are charged and correctly installed.
• Re-pair the helicopter and remote control as described in Section 5.4.
• Ensure you are within the remote control's operating range (80-100 meters).

8.2 Helicopter Flies Unstably

• Check for any damaged or bent propeller blades and replace them if necessary.
• Ensure the helicopter is placed on a flat, level surface before takeoff for proper gyroscope calibration.
• Verify that the battery is fully charged.
• Avoid flying in windy conditions, as the helicopter's anti-wind ability is not specified.

8.3 Signal Loss and Crash Prevention Function

The aircraft is equipped with a signal loss and crash prevention function. If the remote control signal is lost or abnormal (indoors or outdoors), the aircraft will maintain its current altitude for 2 seconds and then slowly land.

• If signal is lost, immediately move the remote control closer to the helicopter.
• Before the aircraft lands, restart the remote control (if necessary) and push the throttle lever up and down to reconnect to the aircraft for further control.
