2. Key Features

• Anti-interference and Stable Control: 2.4GHz FHSS spread spectrum technology with 67 channels ensures strong anti-interference capabilities and a stable control distance of up to 400 meters. Multiple users can operate simultaneously without interference.
• 5 Channels and Programmable Dual Mix Control: Designed for various RC vehicles including crawlers, tanks, bashers, and boats. Two arbitrary channels can be configured for mix control, with an ON/OFF switch.
• Integrated R6FG Gyroscope: The included R6FG receivers feature a built-in gyroscope for enhanced vehicle stability, preventing high-speed drifting. Gyro sensitivity is adjustable via the RC4GS V3 VR switch, ideal for drift and on-road cars.
• 30 Model Memory & ID SEED Function & Cruise Control: Stores settings for up to 30 models. Each model can have separate low voltage and low RSSI alarm settings. The ID SEED function allows assigning one vehicle to run when powered on. Compatible with R7FG/R6FG/R6F/R4FGM/R8FG/R8FGH/R12F/R16F receivers.
• Vehicle Voltage Telemetry: Real-time vehicle battery voltage and RSSI information displayed on the RC4GS V3 radio screen. Requires an R7FG/R8FG/R8FGH telemetry receiver for this function.
• Powerful Functions: Includes voltage telemetry, EPA (End Point Adjustment), ABS (Anti-lock Braking System), fail-safe, dual-rate, timer, cruise control, FPV head tracking, low power alarm. Channels CH3-CH5 are customizable for VR and tactile switch functions.

4. Setup

4.1 Battery Installation

The RC4GS V3 transmitter supports 6x AA batteries or a 2S-4S LiPo battery. Batteries are not included.

1. Open the battery compartment cover on the bottom of the transmitter.
2. Insert 6 AA batteries, ensuring correct polarity, or connect a compatible 2S-4S LiPo battery to the JST connector.
3. Close the battery compartment cover securely.

Figure 3: Battery installation options for the RC4GS V3 transmitter.

4.2 Receiver Connection

Connect the R6FG receiver to your RC vehicle's ESC and servos. Ensure correct channel allocation (e.g., CH1 for steering, CH2 for throttle).

Figure 4: Example of receiver and telemetry cable connection.

For real-time voltage telemetry, connect the telemetry cable to the receiver's telemetry port (2-pin) and the other two plugs to the vehicle's battery and ESC, respectively. Refer to the receiver diagram for port identification.

4.3 Binding the Transmitter and Receiver

To establish communication between the transmitter and receiver:

1. Turn on the transmitter.
2. Press and hold the binding button on the receiver while powering it on. The receiver's LED will flash rapidly.
3. Release the binding button. The LED will continue to flash.
4. On the transmitter, navigate to the binding menu (refer to the operating section for menu navigation).
5. Initiate the binding process on the transmitter. The receiver's LED should turn solid, indicating successful binding.
6. Power cycle both the transmitter and receiver to confirm the connection.

5. Operating Instructions

5.1 Basic Controls

• Steering Wheel: Controls the steering of the vehicle.
• Throttle Trigger: Controls forward and reverse movement, and braking.
• Display Screen: Shows current settings, telemetry data, and menu options.
• Navigation Buttons (Exit, Dec(-), Inc(+), Enter): Used to navigate menus and adjust settings.
• Switches/Knobs: Customizable for various functions (e.g., dual rate, auxiliary channels).

5.2 Dual Rate Function

Dual Rate (D/R) allows you to adjust the maximum travel amount of a servo. This is useful for limiting steering angle or throttle response for different driving conditions or skill levels. The adjustable range is from 0 (minimum travel) to 100 (normal travel amount). If a switch is assigned, you can toggle between different travel amounts.

Figure 6: Dual Rate in action, allowing adjustment of servo travel for various driving scenarios.

To assign a switch to control Dual Rate:

1. Power on the transmitter.
2. Long press the "Exit" and "Enter" buttons simultaneously to access the setting page.
3. Navigate to menu item 13, "D/R" (Dual Rate).
4. Select "SW" (Switch) and choose a switch (e.g., LK-D) to control the dual rate.
5. Adjust the travel amounts (ST for steering, TH for throttle, CH3-CH7 for auxiliary channels) for both the "UP" and "DOWN" positions of the assigned switch.
6. Press the assigned switch to toggle between the configured travel amounts.

5.3 Telemetry Function

The telemetry function provides real-time feedback from your vehicle to the transmitter screen, including battery voltage and signal strength (RSSI). This helps prevent over-discharge and potential damage to your vehicle's battery.

To utilize telemetry, ensure you are using a compatible receiver (R7FG/R8FG/R8FGH) and the telemetry cable is correctly connected as described in Section 4.2.

5.4 Model Memory

The RC4GS V3 can store settings for up to 30 different models. This allows you to quickly switch between various vehicles without reconfiguring settings each time.

1. Access the model memory menu through the transmitter's settings.
2. Select an empty slot or an existing model to edit.
3. Configure all necessary parameters (e.g., EPA, D/R, sub-trim, channel mixing) for the specific model.
4. Save the settings to the chosen model memory slot.

5.5 Cruise Control

The cruise control function allows the vehicle to maintain a set speed without continuous throttle input. This can be useful for long, steady runs or specific maneuvers.

1. Activate cruise control via the assigned switch or menu option (refer to your transmitter's specific menu for details).
2. Set the desired speed using the throttle trigger.
3. Deactivate cruise control when no longer needed.

6. Maintenance

• Keep the transmitter and receivers clean and free from dust and moisture.
• Store the unit in a dry, cool place away from direct sunlight.
• Remove batteries if the transmitter will not be used for an extended period to prevent leakage.
• Regularly check all connections for secure fit and signs of wear.
• Avoid dropping or subjecting the transmitter to strong impacts.
