I have an AE XP-120 that seems to bind to the receiver, but, the ESC won't calibrate, and just flashes steady green. I tried a Redcat RX/TX, and it calibrated with no issues, so, any idea how to verify if it's the radio or the receiver? I don't have the actual AE pair plug, but, I made a jumper, and did it exactly how the manual said to, and no matter what way I try doing it, it doesn't seem to want to work.
