- Turn on the remote controller.
- Turn on the helicopter.
- Place the helicopter on a flat, level surface.
- Move the throttle stick (left stick) all the way up, then all the way down. The remote controller and helicopter will bind automatically. A successful bind is indicated by a solid light on the helicopter.
Operating Instructions
Pre-Flight Check
- Ensure batteries in both the helicopter and remote controller are fully charged.
- Check that all propellers are securely attached and free from damage.
- Verify that the helicopter and remote controller are properly bound.
- Choose a safe, open flying area.
One-Key Takeoff and Landing
- Takeoff: After binding, press the One-Key Takeoff button on the remote controller. The helicopter will automatically ascend to a stable hovering height.
- Landing: During flight, press the One-Key Landing button. The helicopter will automatically descend and land gently.
Basic Flight Controls (Mode 2 - Left Hand Throttle)
- Left Stick (Throttle/Yaw):
- Up/Down: Controls altitude (throttle).
- Left/Right: Controls yaw (rotation around vertical axis).
- Right Stick (Pitch/Roll):
- Up/Down: Controls pitch (forward/backward movement).
- Left/Right: Controls roll (sideways movement).
6-Axis Gyroscope Stabilization

The helicopter features three adjustable speed modes (Low, Medium, High). You can select the appropriate speed setting on the remote controller to match your flying proficiency and desired flight experience. Start with Low speed for learning and gradually increase as you gain confidence.
Remote Control Range
The 2.4GHz high-frequency remote control system provides a stable and responsive connection with an effective range of 100-120 meters. Always keep the helicopter within this range for optimal control.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the helicopter after each flight. Avoid using water or solvents.
- Propeller Inspection: Regularly check main and tail propellers for cracks, bends, or damage. Replace damaged propellers immediately using the provided spare parts and screwdriver.
- Battery Storage: Store batteries in a cool, dry place, away from direct sunlight and extreme temperatures. For long-term storage, charge batteries to approximately 50% capacity.
- Motor Care: Keep motors free from dust and debris. Avoid prolonged operation in sandy or dusty environments.
- Screw Tightness: Periodically check all screws and fasteners to ensure they are tight. Use the hex wrench and screwdriver as needed.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Helicopter does not respond to remote. | Low battery in helicopter or remote; not bound; out of range. | Charge batteries; re-bind helicopter and remote; operate within range. |
| Helicopter flies erratically or is unstable. | Propellers damaged; gyroscope calibration issue; strong wind. | Inspect/replace propellers; place on flat surface for re-calibration; fly in calm conditions. |
| Helicopter does not lift off. | Low battery; propellers installed incorrectly; throttle not advanced. | Charge battery; ensure propellers are correctly oriented; push throttle stick up. |
| Short flight time. | Battery not fully charged; aging battery. | Ensure full charge; consider replacing battery if performance degrades significantly. |
