This is my first long range build so there's probably a very obvious answer to this question, but which port do I plug a crossfire 8ch into on a TBS Wing Layer? The plug fits into the BST port but when I power the plane the receiver doesn't get powered. I can power and update the receiver just fine but I checked it with a multimeter and the BST port just isn't getting powered. Everything else seems to be getting power fine though so I don't know what I'm doing incorrectly. Does anyone have any ideas about what might be wrong or if I'm just doing something wrong?
