Setup Guide
Package Contents
- 1 x Flysky FS-GT3B Transmitter
- 1 x Flysky FS-GR3E Receiver
- 1 x Antenna Tube
- 1 x Code Matching Line
Battery Installation
The FS-GT3B transmitter requires 8 x 1.5V AA batteries (not included). Open the battery compartment cover on the back of the transmitter and insert the batteries, ensuring correct polarity. Close the cover securely.
Receiver Connection and Binding
The FS-GR3E receiver is a 3-channel unit. Connect your steering servo to Channel 1 and your Electronic Speed Control (ESC) to Channel 2. The ESC provides power to the receiver and controls the direction (forward/reverse) and speed of your RC vehicle.

To bind the transmitter and receiver:
- Ensure the transmitter is turned off.
- Insert the code matching line (bind plug) into the 'BIND/CH3' port on the receiver.
- Connect power to the receiver (e.g., via the ESC). The receiver's LED should flash rapidly.
- While holding down the 'BIND' button on the transmitter, turn on the transmitter.
- The receiver's LED should become solid, indicating successful binding.
- Release the 'BIND' button on the transmitter, then turn off both the transmitter and receiver.
- Remove the code matching line from the receiver.
- Turn on the transmitter first, then the receiver. The system should now be bound and ready for use.

- Ensure both the transmitter and receiver are turned on.
- Loss of Control/Interference:
- Re-bind the transmitter and receiver following the binding procedure in the Setup Guide.
- Ensure no other 2.4GHz devices are operating nearby that could cause interference.
- Check the receiver antenna for damage and ensure it is positioned correctly and not obstructed by metal parts.
- Operate within the specified RF range.
- Incorrect Steering/Throttle Response:
- Check the 'REV' (Reverse) setting for the affected channel on the transmitter's LCD screen. Adjust if the servo/ESC is moving in the opposite direction.
- Adjust 'TRIM' settings to center the steering or throttle.
- Verify servo/ESC connections to the correct receiver channels.
- LCD Screen Issues:
- If the screen is dim or flickering, check battery levels.
