8. Penyelesaian masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Helikopter tidak bertindak balas | Low battery (helicopter or remote), not paired, power switch off | Charge helicopter battery, replace remote batteries, ensure both are ON, re-pair helicopter and remote. |
| Penerbangan/Hanyut Tidak Stabil | Uncalibrated gyroscope, wind interference, damaged propellers | Place on a flat surface and re-calibrate (refer to manual for specific steps), fly in calm conditions, check and replace propellers. |
| Helicopter cannot take off | Low battery, propellers installed incorrectly, motor issue | Charge battery, ensure propellers are correctly attached and spinning freely, contact support if motor is faulty. |
| Isyarat kawalan jauh lemah | Interference, too far from helicopter, low remote battery | Fly in open areas, stay within 100m range, replace remote batteries. |
| One-key inverted flight not working | Insufficient altitude, incorrect button press | Ensure helicopter is at a safe height, press the '3D Switch' button firmly. |
9. Petua Pengguna
- Practice in Low Speed: For beginners, start with the low-speed setting to get accustomed to the controls before moving to medium or high speeds.
- Indoor vs. Outdoor: The optical flow positioning works best indoors or in calm outdoor conditions with clear ground patterns. Avoid flying over reflective surfaces or water.
- Pengurusan Bateri: Pertimbangkan pembelianasing an extra modular battery for extended flight sessions, as each battery provides about 8 minutes of flight time.
- Semakan Pra-Penerbangan: Always perform a quick visual check of the propellers and ensure the battery is secure before each flight.
- Gentle Controls: RC helicopters respond best to smooth, gentle control inputs. Avoid sudden or jerky movements, especially when learning.
