Introduction
The Flysky FS-GT2B is a 2.4GHz 3-channel radio control system designed for RC cars and boats. It utilizes the Automatic Frequency Hopping Digital System (AFHDS) technology, ensuring reliable and interference-free operation. This system operates within the 2.400GHz to 2.4835GHz frequency range, divided into 160 wave bands, providing excellent anti-jamming capabilities and high receiving sensitivity. The transmitter features a built-in antenna and is powered by a rechargeable 3.7V Li-ion battery, offering low power consumption and stable performance.

- Channels: 3 Channels (CH1: Steering, CH2: Throttle, CH3: Auxiliary)
- BIND Port: Used for binding the receiver to the transmitter.
- Antenna: Single antenna for signal reception.
Setup
1. Transmitter Battery Installation and Charging
The FS-GT2B transmitter comes with a built-in rechargeable 3.7V Li-ion battery.
- Open the battery compartment cover located at the bottom of the transmitter.
- Ensure the included 3.7V 800mAh Li-ion battery is correctly inserted with the polarity matching the markings inside the compartment.
- Close the battery compartment cover.
- To charge the transmitter, connect the supplied USB cable to the Micro USB port (labeled CHG or F) on the transmitter and the other end to a USB power source (e.g., computer USB port, USB wall adapter).
- The POWER LED will indicate charging status (refer to the LED indicator section for details).

2. Receiver Connection
Connect the FS-GR3E receiver to your RC model's electronic speed controller (ESC) and steering servo.
- Connect the ESC's throttle cable to the CH2 port on the receiver.
- Connect the steering servo's cable to the CH1 port on the receiver.
- If using an auxiliary device (e.g., lights, winch), connect its cable to the CH3 port.
- Ensure all connections are made with correct polarity (signal, positive, negative).
- Mount the receiver securely in your RC model, ensuring the antenna is positioned away from metal parts and as straight as possible for optimal range. Use the provided antenna tube if necessary.
3. Binding Process (Code Matching)
Binding is the process of linking the transmitter and receiver so they can communicate. This only needs to be done once per receiver.
- Ensure the transmitter is turned OFF.
- Insert the provided binding plug (code matching line) into the BIND port on the FS-GR3E receiver.
- Power on the RC model (and thus the receiver) via the ESC. The receiver's LED should start flashing rapidly, indicating it's in binding mode.
- While holding down the BIND button on the transmitter (located under the protective cover), turn on the transmitter.
- The transmitter's POWER LED and the receiver's LED should both become solid, indicating a successful bind.
- Release the BIND button on the transmitter.
- Turn off the receiver (by turning off the RC model's power).
- Remove the binding plug from the receiver.
- Turn on the transmitter, then turn on the receiver. The system should now be linked and ready for operation.
Operating Instructions
Basic Controls
- Steering Wheel: Rotate the steering wheel clockwise to turn right, and counter-clockwise to turn left.
- Throttle Trigger: Pull the trigger towards you for forward movement (acceleration). Push the trigger away from you for braking or reverse movement.
Image: Diagram illustrating Steering Wheel Control. This image shows how rotating the steering wheel left or right corresponds to the RC vehicle's steering direction.

Adjustments (Under Protective Cover)
Lift the protective cover on the top of the transmitter to access the adjustment knobs and switches.
Image: View of the Flysky FS-GT2B Transmitter with the protective cover open, revealing the adjustment controls. This image clearly shows the trim knobs, reverse switches, and dual rate dial.
- ST TRIM (Steering Trim): Use this knob to fine-tune the steering neutral position. If your RC model pulls to one side when the steering wheel is centered, adjust this trim until it drives straight.
- TH TRIM (Throttle Trim): Use this knob to fine-tune the throttle neutral position. If your RC model creeps forward or backward when the throttle trigger is released, adjust this trim until it remains stationary.
- ST REV (Steering Reverse Switch): Flips the direction of the steering channel. If your model steers left when you turn the wheel right, flip this switch.
- TH REV (Throttle Reverse Switch): Flips the direction of the throttle channel. If your model goes in reverse when you pull the trigger forward, flip this switch.
- D/R (Dual Rate): Adjusts the maximum steering angle. Turning this knob allows you to limit how much the wheels turn, which can be useful for controlling sensitivity or preventing over-steering.
- CH3 Button: This button controls the third channel. Its function depends on what auxiliary device is connected to CH3 on the receiver. It typically acts as an on/off switch or a two-position switch.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the transmitter and receiver. Avoid using solvents or harsh chemicals.
- Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care:
- Charge the transmitter battery regularly, even if not in use, to maintain its health.
- Do not overcharge or deep discharge the Li-ion battery.
- If storing for an extended period, charge the battery to approximately 50% capacity.
- Antenna: Ensure the receiver antenna is not cut, bent sharply, or damaged, as this can significantly reduce range.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to transmitter | Battery not charged or incorrectly installed. | Charge the transmitter battery. Check battery polarity. |
| No control over RC model | Not bound, receiver not powered, or connections incorrect. | Perform binding process again. Ensure receiver is powered and all cables are correctly connected. |
| RC model moves in wrong direction | Channel reverse switch is set incorrectly. | Adjust ST REV or TH REV switch on the transmitter. |
| RC model does not drive straight or stop at neutral | Trim settings are off. | Adjust ST TRIM or TH TRIM knobs until the model operates correctly. |
| Limited range or intermittent signal | Receiver antenna placement, interference, or low battery. | Ensure receiver antenna is straight and clear of metal. Avoid operating near other 2.4GHz devices. Charge transmitter battery. |
