How to bind the transmitter to the receiver? 1). Check and make sure all wires are properly connected and the remote is turned off. Insert the plug into CH3 on the receiver. 2). Turn on the ESC; you will see the receiver’s red light flashing. 3). Press and hold the button on the remote, then turn on the remote. 4). Observe the transmitter light change from flashing red to solid red, and the receiver light also become solid red. 5). Once both lights are solid red, the transmitter and receiver are successfully bound. Remove the plug from CH3 (this step is essential for the remote to set throttle midpoint and enable fail-safe function). 6). Test the connection by turning off the transmitter; the receiver light should start flashing. When you turn the transmitter back on, the light should return to solid red. Before operation, test the fail-safe function by turning off the remote. If the motor stops, the fail-safe is working properly. If the motor continues to run, repeat steps 1 through 6.
