6. Betjeningsvejledning
6.1. Fjernbetjening overview

- Afbryderen: Tænder/slukker fjernbetjeningen.
- Strømindikator: Shows remote controller power status.
- Hastighedskonvertering: Adjusts flight speed (e.g., beginner, intermediate, expert).
- One-Tap Takeoff / One-Tap Landing: Starter automatisk start eller landing.
- Optical Flow Switch: Activates/deactivates optical flow positioning for enhanced stability.
- Throttle/Direction Rocker (Left Joystick): Styrer højde (op/ned) og drejning (venstre/højre rotation).
- Left/Right / Forward/Back Joystick (Right Joystick): Controls forward/backward movement and left/right side flying.
- Front/Back Fine-tuning Button: Adjusts forward/backward trim.
- Left and Right Fine Adjustment Keys: Adjusts left/right trim.

6.3. Avancerede flyfunktioner
- 6G-tilstand: The helicopter utilizes a 6-axis gyroscope for stable flight, making it particularly suitable for beginners. This mode helps maintain stability and makes control easier.
- Air Pressure Height Setting: This feature allows the helicopter to maintain a stable altitude automatically, reducing the need for constant throttle adjustments.
- Optisk flowpositionering: Activate the Optical Flow Switch (5) for enhanced stability, especially in indoor environments or when precise hovering is desired. This feature helps the helicopter maintain its position.
- Signal Loss and Crash Prevention: If the remote control signal is lost (either indoors or outdoors), the helicopter will maintain its current altitude for 2 seconds and then slowly descend to land. During this descent, if the remote control is reconnected (by restarting the remote and moving the throttle rocker), you can regain control.

7. Vedligeholdelse
- Rensning: Use a soft, dry cloth to clean the helicopter. Do not use water or solvents.
- Propelinspektion: Regularly check propellers for damage (cracks, bends). Replace damaged blades immediately using the provided spare blades and screwdriver.
- Motorpleje: Keep motors free from dust and debris. Avoid prolonged operation at maximum throttle to prevent overheating.
- Batteriopbevaring: For long-term storage, charge the Li-ion battery to about 50% and store it in a cool, dry place. Remove AA batteries from the remote controller when not in use for extended periods.
- Generel inspektion: Kontrollér regelmæssigt alle skruer og forbindelser for at sikre, at de er fastgjort.
8. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Helikopteren reagerer ikke på fjernbetjeningen. | Not paired, low battery (helicopter or remote), remote control out of range. | Ensure proper pairing (Section 5.3). Charge helicopter battery. Replace remote control batteries. Ensure helicopter is within 80m range. |
| Helikopteren flyver uregelmæssigt eller er ustabil. | Damaged propellers, incorrect trim settings, strong wind, gyroscope calibration issue. | Check and replace damaged propellers. Adjust trim settings (Section 6.1). Fly in calm conditions. Re-calibrate gyroscope (refer to manual for specific steps if available, otherwise power cycle). |
| Helicopter does not take off or has weak lift. | Low helicopter battery, damaged motors/gears, propellers installed incorrectly. | Charge helicopter battery fully. Inspect motors and gears for damage. Ensure propellers are installed correctly and not obstructed. |
| Remote control indicator light flashes continuously. | Low remote control battery, not paired with helicopter. | Replace AA batteries in the remote control. Perform pairing procedure (Section 5.3). |
9. Brugertips
- Øvelse i 6G-tilstand: For beginners, start flying in 6G mode to benefit from the enhanced stability provided by the 6-axis gyroscope.
- Indendørs træning: Begin practicing in a spacious indoor area before attempting outdoor flights, especially to get accustomed to the controls.
- Tjek vejret: Always check wind conditions before flying outdoors. Even moderate wind can significantly affect control and stability.
- Batteristyring: Avoid completely draining the helicopter battery during flight. Land the helicopter when you notice a decrease in power or responsiveness to prolong battery life.
