- Connect the intelligent battery to the USB charger.
- The charger's indicator light will show the charging status. Refer to the charger's specific instructions for light indications (typically red for charging, green for fully charged).
- Charging time is approximately 70 minutes. Do not overcharge the battery.
4.2 Battery Installation
- Ensure the helicopter is powered off.
- Locate the battery compartment on the helicopter.
- Carefully insert the charged intelligent battery into the compartment, ensuring the connectors align.
- Connect the battery to the helicopter's power port.
- Secure the battery compartment cover.

5. Operating Instructions
5.1 Basic Controls
The 2.4G RC remote control typically features the following functions:
- Throttle (Left Stick Up/Down): Controls the helicopter's altitude.
- Rudder (Left Stick Left/Right): Controls the helicopter's rotation around its vertical axis (yaw).
- Elevator (Right Stick Up/Down): Controls forward and backward movement (pitch).
- Aileron (Right Stick Left/Right): Controls sideways movement (roll).
- 3D/6G Mode Switch: Toggles between flight modes.
5.2 Flight Modes (3D/6G Dual Mode)
- 6G (Self-Stabilizing) Mode: Ideal for beginners. The 6-axis gyroscope and optical flow positioning system provide enhanced stability, automatically correcting the helicopter's attitude to maintain level flight. This mode simplifies control, making it easier to learn.
- 3D (Acrobatic) Mode: For experienced pilots. This mode allows for advanced maneuvers and inverted flight, offering full control without automatic stabilization. Switch to this mode only after mastering 6G mode.

5.3 First Flight Tips
- Choose an open, calm environment with no wind.
- Start in 6G mode for maximum stability.
- Gently increase the throttle to lift off slowly. Practice hovering at a low altitude.
- Make small, precise control inputs. Avoid sudden movements.
- If you lose control, immediately reduce the throttle to zero to prevent damage.
- Practice basic maneuvers like hovering, forward/backward flight, and turning before attempting advanced operations.

6.2 Storage
- Store the helicopter and remote control in a cool, dry place, away from direct sunlight and extreme temperatures.
