2. Safety Information
- Battery Safety: Always use the specified battery types (8 x 1.5V AA batteries for the transmitter, 4.0-6.5V DC for the receiver). Do not mix old and new batteries, or different types of batteries. Remove batteries if the device will not be used for an extended period.
- Operating Environment: Avoid operating the RC system in wet conditions, extreme temperatures, or areas with strong electromagnetic interference. Ensure a clear line of sight between the transmitter and receiver.
- Proper Handling: Handle the transmitter and receiver with care. Avoid dropping or subjecting them to excessive force. Keep away from small children.
- Pre-Operation Check: Before each use, verify that all connections are secure, batteries are charged, and controls respond correctly.
3. Setup
3.1 Unpacking and Components
Carefully unpack all components and ensure the following items are present:
- 1 x Flysky FS-GT3B Transmitter

3.2 Transmitter Battery Installation
The FS-GT3B transmitter requires eight (8) 1.5V AA batteries (not included).
- Locate the battery compartment on the bottom of the transmitter handle.
- Slide open the battery cover.
- Insert eight AA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Close the battery cover securely.
3.3 Receiver Connection
Connect the receiver to your RC vehicle's components as follows:
- Channel 1 (CH1): Connect the steering servo to this port.
- Channel 2 (CH2): Connect the Electronic Speed Control (ESC) to this port. The ESC will also provide power to the receiver.
- Channel 3 (CH3): This is an auxiliary channel for additional functions if your model supports them.
- Ensure all connections are firm and correctly oriented.
3.4 Binding the Transmitter and Receiver
Binding is the process of linking the transmitter and receiver so they can communicate.
- Ensure the transmitter is turned OFF.
- Insert the included "Code Matching Line" (binding plug) into the BIND/CH3 port on the receiver.
- Power on the receiver (usually by connecting the ESC to the battery). The receiver's LED should flash rapidly, indicating it's in binding mode.
- While holding down the BIND button on the transmitter (located near the antenna), turn the transmitter ON.
- The transmitter's LCD screen should display "BINDING..." or similar. The receiver's LED should turn solid, indicating successful binding.
- Release the BIND button on the transmitter.
- Turn off both the transmitter and the receiver.
- Remove the binding plug from the receiver.
- Turn on the transmitter first, then the receiver. The receiver's LED should be solid, confirming a successful bind.

This video provides a comprehensive overview of the Flysky FS-GT3B transmitter and FS-GR3E receiver, demonstrating their features and basic operation, including the binding process and various settings adjustments.
4. Operating Instructions
The FS-GT3B offers precise control and a range of adjustable settings via its LCD screen and control buttons.
4.1 Basic Controls
- Steering Wheel: Controls the direction of your RC vehicle (left/right).
- Throttle Trigger: Controls the speed and direction (forward/reverse) of your RC vehicle. Pull for forward, push for reverse.
4.2 LCD Display and Navigation
The LCD screen provides access to various settings and real-time information. Use the buttons and the rotary knob to navigate menus and adjust values.

4.3 Advanced Settings
The transmitter allows for fine-tuning of various parameters to optimize performance for different vehicles and driving styles.
- Model Memory: The transmitter can store settings for multiple RC models. Navigate to the "MODEL" menu to select or create new model profiles.
- Reverse (REV): Adjust the direction of each channel (steering, throttle, auxiliary). If your servo or ESC operates in the opposite direction, use this setting to reverse it.
Video 2: Adjusting Reverse Settings
This segment demonstrates how to access and adjust the reverse settings for different channels on the Flysky FS-GT3B transmitter, allowing you to change the operational direction of servos or the ESC.
- Trim: Fine-tune the neutral position of steering and throttle. Use the ST.TRIM and TH.TRIM buttons to make small adjustments.
- Dual Rate (D/R): Adjust the maximum steering angle or throttle response. This limits how much the servo or ESC will move from its neutral position.
- End Point Adjustment (EPA): Sets the maximum travel for each channel's direction. This is useful for preventing over-steering or over-throttling, protecting your servos and ESC.
Video 3: Adjusting End Point Adjustment (EPA)
This video segment illustrates the process of setting End Point Adjustment (EPA) on the Flysky FS-GT3B, which limits the maximum travel of steering and throttle channels to prevent over-extension and protect components.
- Exponential (EXP): Adjusts the sensitivity of the control around the center point. A negative EXP value makes the control less sensitive around the center, and more sensitive towards the ends, while a positive value does the opposite.
- ABS Settings: Provides anti-lock braking system functionality for RC cars, allowing for more controlled braking.
- DSC Port: A 3.5mm port for outputting PPM signals, often used for simulators (VRC - Virtual RC).
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the transmitter and receiver. Avoid using solvents or abrasive cleaners.
- Storage: Store the RC system in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries from the transmitter if storing for long periods.
- Battery Care: Always dispose of old batteries responsibly. If using rechargeable batteries, follow the manufacturer's charging guidelines.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Transmitter does not power on. | Dead or incorrectly installed batteries. | Check battery polarity; replace with fresh AA batteries. |
| No control response from vehicle. | Receiver not bound to transmitter; loose connections; receiver not powered. | Perform binding procedure (Section 3.4); check all cable connections; ensure receiver is powered by ESC. |
| Erratic or intermittent control. | Interference; low transmitter/receiver battery; damaged antenna. | Move to an area with less interference; replace batteries; inspect antenna for damage. |
| Steering/Throttle operates in reverse. | Channel reverse setting is incorrect. | Adjust the "Reverse" setting for the affected channel (Section 4.3). |
