Setup and Binding
To establish communication between your transmitter and receiver, follow these binding instructions. Ensure all components are powered off before starting.
Binding Procedure
- Connect the receiver to a power source (e.g., ESC with BEC or a separate receiver battery).
- Power on the receiver. The LED on the receiver should flash, indicating it is in binding mode.
- Power on the transmitter.
- Locate the "BIND" button on the receiver. Press and hold the "BIND" button for approximately 3 seconds.
- Observe the LED on the receiver. Once the LED changes from fast flashing to a solid light, the binding process is complete.
- Verify binding by connecting a servo to Channel 1 on the receiver and turning the steering wheel on the transmitter. The servo should respond.
Video Description: This video demonstrates the binding method for a DUMBORC X4 Radio Transmitter with an X6F Receiver. It shows how to power on the receiver, then the transmitter, and then press the bind button on the receiver until the LED light becomes solid, indicating successful binding. A servo is then connected to verify the binding.

Operating the Transmitter
The 2.4GHz Radio Transmitter features several adjustable controls to fine-tune your RC vehicle's performance.
- Steering Trim (ST/TRIM): Adjusts the neutral position of the steering. Use this to make the vehicle drive straight when the steering wheel is centered.
- Throttle Trim (TH/TRIM): Adjusts the neutral position of the throttle. Use this to ensure the vehicle remains stationary when the throttle trigger is released.
- Steering Dual Rate (ST D/R): Adjusts the maximum steering angle.
- Throttle Dual Rate (TH D/R): Adjusts the maximum throttle output.
- Steering Direction Reverse Switch (ST DIR): Reverses the steering direction.
- Throttle Direction Reverse Switch (TH DIR): Reverses the throttle direction.
- Trigger: Controls forward/reverse movement and speed.
- Control Wheel: Controls left/right steering.
- Power ON/OFF: Turns the transmitter on or off.
- LED Indicator: Shows the power and binding status.
Troubleshooting
If you encounter issues with your HAIBOXING 2.4GHz Radio Transmitter, refer to the following common troubleshooting steps:
Throttle or Steering Not Responding
- Check Binding: Ensure the transmitter and receiver are properly bound. Refer to the "Setup and Binding" section.
- Adjust Throttle Trim (TH/TRIM): If the steering works but the throttle does not, adjust the TH/TRIM knob to the neutral (center) position. The ESC may not recognize the throttle input if the trim is off-center.
- Adjust Throttle Dual Rate (TH D/R): If the motor does not respond or moves slowly, adjust the TH D/R to its maximum value.
- Adjust Steering Dual Rate (ST D/R): If there is no steering response, adjust the ST D/R to its maximum value.
- ESC Calibration: If the issue persists, check the Electronic Speed Controller (ESC). Calibrate it and ensure it is in the correct two-way working mode.
Video Description: This video addresses common issues where the throttle or steering may not work on an RC vehicle. It demonstrates how to adjust the throttle sub-trim and throttle dual rate (TH D/R) on the transmitter to resolve these problems, ensuring the ESC recognizes the throttle input and the motor responds correctly.
