Impostare
1. Installazione della batteria del trasmettitore
The Futaba 3PRKA transmitter requires four "AA" alkaline batteries. Ensure correct polarity when inserting the batteries.
- Open the battery compartment cover located on the bottom of the transmitter.
- Insert four "AA" batteries according to the polarity markings (+/-) inside the compartment.
- Chiudere saldamente il coperchio del vano batterie.
Attenzione: Do not mix old and new batteries, or different types of batteries. Remove batteries if the transmitter will not be used for an extended period.
2. Receiver Installation and Connection (R203GF)
The R203GF receiver is compact and designed for easy installation in your model. Ensure the receiver is mounted securely and protected from vibrations and moisture.

- Mount the R203GF receiver in a suitable location within your model, away from electrical noise sources (e.g., motor, ESC). Use double-sided tape or a receiver box for secure mounting.
- Connect your servos to the corresponding channels on the receiver:
- Canale 1: Servosterzo
- Channel 2: Throttle Servo/ESC
- Channel 3: Auxiliary (e.g., lights, gear shift)
- "B" Port: Battery/Power source (4.8V-7.4V)
- Assicurarsi che tutti i collegamenti siano saldi e correttamente orientati.
3. Collegamento del trasmettitore e del ricevitore
The 3PRKA transmitter and R203GF receiver are typically linked at the factory. If re-linking is necessary, follow these steps:
- Accendere il trasmettitore.
- Turn on the receiver. The receiver's LED will flash red.
- Press and hold the "SW" (Switch) button on the receiver for approximately 2 seconds. The LED will change from flashing red to solid green, indicating successful linking.
- Release the "SW" button.
- Turn off both the receiver and transmitter, then turn them back on to confirm the link.
Nota: If the LED flashes red and green simultaneously, it indicates an un-linked state or an error. Repeat the linking process.
Istruzioni per l'uso
Controlli di base
- Volante: Controls the direction of the model. Turn clockwise for right, counter-clockwise for left.
- Grilletto dell'acceleratore: Controls the speed and direction (forward/reverse) of the model. Pull for forward, push for reverse/brake.

Adjustments and Functions
The 3PRKA features several adjustable controls located under a protective cover on the side of the transmitter. Gently slide the cover to access these controls.

| Controllare | Descrizione |
|---|---|
| Rivestimento dello sterzo (ST.TRIM) | Adjusts the neutral position of the steering servo. Use to make the model track straight when the steering wheel is centered. |
| Trim acceleratore (TH.TRIM) | Adjusts the neutral position of the throttle servo/ESC. Use to ensure the motor stops when the throttle trigger is at neutral. |
| Steering Dual Rate (D/R ST) | A thumb dial that adjusts the maximum steering angle. Turn clockwise for more steering throw, counter-clockwise for less. Useful for tuning steering response. |
| Throttle End Point Adjustment (TH.EPA) | Adjusts the maximum travel of the throttle servo/ESC in both forward (High) and reverse (Low) directions. Prevents over-travel and damage to mechanical linkages. |
| Servo Reversing (ST.REV / TH.REV) | Switches the direction of servo movement. If a servo moves in the opposite direction to your input, flip the corresponding switch. |
| Channel 3 Switching (CH3) | A switch for controlling the third channel, typically used for auxiliary functions like lights or gear shifting. |
| Throttle Fail-Safe (F/S) | Automatically moves the throttle to a preset position (usually neutral or brake) if the radio signal is lost or interrupted. This prevents the model from running away. The R203GF receiver has a battery fail-safe voltage of 3.8V for 4-cell NiCd/NiMH batteries. |
| Avviso di batteria scarica | A flashing LED on the transmitter indicates when the battery voltage is low, signaling it's time to replace the batteries. |
Manutenzione
- Pulizia: Utilizzare un panno morbido e asciutto per pulire il trasmettitore e il ricevitore. Evitare l'uso di solventi o prodotti chimici aggressivi.
- Magazzinaggio: Store the system in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries from the transmitter if storing for extended periods.
- Cura della batteria: Always use fresh batteries for optimal performance. Dispose of used batteries responsibly.
- Antenna: The transmitter has a built-in antenna. Avoid obstructing it during operation. For the receiver, ensure the antenna wire is not cut or damaged and is positioned correctly for optimal range.
Risoluzione dei problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Nessuna alimentazione al trasmettitore | Batterie scariche o installate in modo errato | Controllare la polarità delle batterie; sostituirle con batterie "AA" nuove. |
| Model does not respond to controls | Not linked; receiver not powered; incorrect connections; low transmitter battery | Perform linking procedure; check receiver power supply; verify all servo/ESC connections; replace transmitter batteries. |
| I servi si muovono nella direzione sbagliata | Servo reversing switch set incorrectly | Flip the corresponding ST.REV or TH.REV switch. |
| Model pulls to one side (steering) | Steering trim not centered | Adjust the ST.TRIM dial until the model tracks straight. |
| Motor runs slightly at neutral (throttle) | Trim dell'acceleratore non centrato | Adjust the TH.TRIM dial until the motor stops at neutral. |
| Limited steering angle or binding | Steering Dual Rate (D/R ST) set too low; mechanical binding | Increase D/R ST; check for mechanical obstructions in steering linkage. |
| Gamma ridotta o controllo intermittente | Interferenza; basso livello della batteriatage; damaged receiver antenna | Operate in an open area away from other 2.4GHz devices; replace batteries; inspect receiver antenna for damage. |
