Try this guys.
Remove Steering servo and ESC.
You want to bind Tx and RX only. Use the battery cage(AA batteries that come with System) to power up the RX. Follow 4PLS manual. Hold down button on RX till grn LED. Turn off TX, connect Steering servo & ESC. Then Calibrate your ESC as to ESC manual if needed. Most Brushless motor has to be done.
Good Luck!!
