2.3 Composants du produit

Figure 1: The WFLY X9 RC Transmitter and its accompanying RG206S Receiver. The transmitter features a pistol-grip design with a steering wheel and a screen on top, while the receiver is a small, rectangular unit with multiple ports.

Figure 2 : Un aperçu détaillé view of the RG206S Receiver, showing its channel ports (1-6), external voltage detection port (Ext. Volt), GPS port, and W.BUS port. A 'SET' button is also visible for binding and configuration.

Figure 3: The 3.5-inch capacitive touch screen interface of the WFLY X9 transmitter. The screen displays various parameters such as timer, RX voltage, vol externetage, speed, and channel outputs (CH1, CH2, CH3). Menu, Lock, and User menu buttons are visible on the screen.

Figure 4: Illustration of the servo channel limit function. This feature allows setting the servo angle to prevent mechanical damage by ensuring servo output remains within the mechanical travel limits of the connected component.
3. Installation
3.1 Installation de la batterie de l'émetteur
- Locate the battery compartment on the bottom of the WFLY X9 transmitter.
- Ouvrez le couvercle du compartiment à piles.
- Insert either a 1S LiPo battery or four AA dry batteries, ensuring correct polarity.
- Fermez soigneusement le couvercle du compartiment à piles.
Note: The transmitter supports a working voltage gamme de 3.5V à 6.0V.
3.2 Connexion du récepteur
- Connect the RG206S receiver to your RC vehicle's electronic speed controller (ESC) and servos.
- Ensure that the channels (CH1-CH6) on the receiver correspond to the correct functions (e.g., steering, throttle) on your vehicle.
- If using GPS or external voltage detection, connect the respective modules to the 'GPS' and 'Ext. Volt' ports on the receiver.
Note: The receiver supports a working voltage gamme de 3.5V à 9.0V.
3.3 Procédure contraignante
Pour établir la communication entre l'émetteur et le récepteur, un processus de liaison est nécessaire :
- Éteignez l’émetteur et le récepteur.
- Press and hold the 'SET' button on the RG206S receiver while powering it on. The receiver's LED indicator will flash rapidly, indicating it is in binding mode.
- Turn on the WFLY X9 transmitter.
- Navigate to the binding menu on the transmitter's touch screen (refer to the on-screen interface for specific steps).
- Initiate the binding process from the transmitter.
- Once binding is successful, the receiver's LED indicator will turn solid, and the transmitter will display a successful connection message.
- Turn off both devices and then power them on normally to confirm the connection.
4. Fonctionnement
