5. Installation
5.1 Installation de l'hélice
- Assurez-vous que le drone est éteint et que la batterie est déconnectée.
- Identify the correct rotation direction for each propeller (CW and CCW).
- Align the propeller with the motor shaft and press down firmly.
- Secure the propeller with the provided propeller nuts, ensuring they are tightened but not overtightened.
5.2 Connexion de la batterie
- Place a battery anti-slip pad on the top plate of the drone.
- Secure the recommended 6S LiPo battery (1500mAh – 2000mAh) to the drone using the M20*250mm battery straps. Ensure the battery is centered and tightly secured.
- Connect the XT60 battery connector to the drone's power port.
5.3 Receiver Binding (ELRS 2.4G / TBS Nano RX)
Refer to your specific receiver's manual for detailed binding instructions. Generally, the process involves:
- Power on your remote controller and set it to binding mode.
- Power on the drone. The receiver's LED should indicate it's ready for binding (e.g., flashing rapidly).
- Initiate the binding process on your remote controller.
- Une fois la connexion établie, la LED du récepteur doit rester allumée, indiquant une connexion réussie.
5.4 FPV System Setup (O4 Air Unit Pro)
Ensure your FPV goggles are compatible with the O4 Air Unit Pro Transmission Module. Power on your goggles and the drone. The video feed should automatically connect. Adjust channel and frequency settings if necessary via your goggles' menu.
6. Mode d'emploi
6.1 Arming/Disarming Motors
To arm the motors, move both sticks on your remote controller to the bottom-right corner (or as configured in Betaflight). The motors will spin up slowly. To disarm, move both sticks to the bottom-left corner.
6.2 Commandes de vol de base
- Étrangler: Contrôle l'altitude (manche gauche haut/bas).
- Embardée: Rotates the drone left or right (left stick left/right).
- Pas: Tilts the drone forward or backward (right stick up/down).
- rouler: Tilts the drone left or right (right stick left/right).
6.3 Modes de vol avancés
The Vapor-D6 O4 Pro supports various flight modes configurable in Betaflight. Common modes include:
- Mode angle : Self-leveling mode, suitable for stable cruising.
- Mode Acro : Manual mode, offering full control for freestyle and racing.
- GPS Rescue (with optional GPS): If equipped with the GEP-M10 GPS module, this mode can assist in returning the drone to a predefined home point in case of signal loss or emergency.
7. Entretien
- Inspection de l'hélice : Regularly check propellers for any damage, bends, or cracks. Replace damaged propellers immediately.
- Inspection du cadre : Inspect the carbon fiber frame and arms for any signs of stress, cracks, or damage after hard landings or crashes.
- Nettoyage du moteur : Keep motors free from dirt, dust, and debris. Use compressed air or a soft brush to clean them.
- Serrage des vis : Periodically check all screws for tightness, especially those securing motors and frame components.
- Mises à jour du micrologiciel : Keep your flight controller (GEP-F722-HD v2) and O4 Air Unit Pro firmware updated to the latest versions for optimal performance and bug fixes.
