3. Trasmettitore Overview
Figura 1: Fronte view of the Futaba 4YF 4-Channel 2.4GHz FHSS Transmitter. This image displays the main controls including the two joysticks, trim levers, servo reverse switches, power switch, and battery indicator LEDs.
3.1. Controlli e indicatori
- Joysticks (Sticks): Control primary functions such as Aileron, Elevator, Throttle, and Rudder.
- Leve di regolazione: Fine-tune the neutral position of each control channel for precise adjustments.
- Servo Reverse Switches: Reverse the direction of servo travel for each channel (AIL, ELE, THR, RUD). These are located below the main control panel.
- Interruttore di alimentazione: Turns the transmitter on and off. Located on the right side of the transmitter.
- Battery Meter (LEDs): A green LED indicates sufficient power, while a red LED indicates low battery status, signaling the need for replacement. Located above the servo reverse switches.
- Power Down Switch: Reduces RF power for 90 seconds to simplify ground checks for interference. Located on the left side of the transmitter.
4. Impostazione
4.1. Installazione della batteria del trasmettitore
- Aprire il coperchio del vano batterie sul retro del trasmettitore.
- Inserire quattro (4) batterie AA, assicurandosi della corretta polarità (+/-) come indicato all'interno del vano.
- Chiudere saldamente il coperchio del vano batterie.
4.2. Receiver Installation and Connection
The R2004GF receiver features a flexible coaxial antenna. Position this antenna inside your model for optimal reception, ensuring it is not obstructed by metal or carbon fiber components.
- Mount the R2004GF receiver securely within your model, away from motors, Electronic Speed Controllers (ESCs), and other potential sources of electrical noise.
- Connect the servos and other components (e.g., ESC) to the appropriate channels on the receiver. Refer to your model's instructions for specific connections.
- Ensure the receiver's antenna is routed and secured to maximize signal reception and prevent damage.
4.3. Linking Transmitter and Receiver
The transmitter and receiver link securely with a simple push-button process, eliminating the need for binding plugs.
- Accendere il trasmettitore.
- Accendere il ricevitore.
- Press and hold the linking button on the receiver until the LED on the receiver changes state (e.g., solid green).
- Release the button. The system is now linked.
- Turn off both the receiver and transmitter, then power them on again to confirm the link and proper operation.
5. Istruzioni per l'uso
5.1. Controlli pre-volo
- Ensure the transmitter batteries are fully charged or have sufficient power (Green LED illuminated).
- Verify all control surfaces move freely and in the correct direction in response to stick inputs.
- Check for any loose connections, damaged wires, or compromised components on both the transmitter and the model.
5.2. Servo Reversing
The 4YF transmitter features all-channel servo reversing switches. These switches allow you to change the direction of servo travel for Aileron (AIL), Elevator (ELE), Throttle (THR), and Rudder (RUD) channels. This is useful for ensuring control surfaces respond correctly to stick inputs, depending on your model's setup.
- Locate the servo reverse switches on the lower front panel of the transmitter.
- Move the corresponding switch (labeled NOR/REV) to change the servo direction for that specific channel.
- Always test servo direction after making changes to prevent unexpected model behavior.
5.3. Power Down Mode
The Power Down mode temporarily reduces the RF output power of the transmitter for 90 seconds. This feature is designed to assist in ground checks for potential interference without affecting the normal operation range during flight.
- To activate, press the "POWER DOWN SW" button on the left side of the transmitter.
- The mode will automatically deactivate after 90 seconds, returning to full power output.
6. Manutenzione
- Pulizia: Use a soft, dry cloth to clean the transmitter and receiver. Avoid using solvents, abrasive cleaners, or excessive moisture, which can damage electronic components.
- Magazzinaggio: Store the system in a cool, dry place, away from direct sunlight, high humidity, and extreme temperatures. Remove batteries from the transmitter if storing for extended periods to prevent leakage.
- Cura della batteria: Replace transmitter batteries promptly when the red LED illuminates to ensure consistent performance. Always use high-quality AA batteries.
7. Risoluzione Dei Problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Il trasmettitore non si accende. | Batterie scariche o installate in modo errato. | Controllare la polarità delle batterie; sostituirle con batterie AA nuove. |
| Receiver not responding to transmitter. | Not linked; receiver not powered; out of range. | Perform linking procedure (Section 4.3); ensure receiver has power; check operating range. |
| I servocomandi si muovono nella direzione sbagliata. | Incorrect servo reverse switch setting. | Adjust the corresponding servo reverse switch (NOR/REV) as described in Section 5.2. |
| Controllo intermittente o perdita del segnale. | Interference; damaged antenna; low transmitter battery. | Check for local interference sources; inspect receiver antenna for damage; replace transmitter batteries. |
