Hey! I’m new to fpv and purchased the iFlight Nazgul 5 (4s) as my first drone, only to be unable to bind it to my transmitter. When I put the Qx7 in register/bind mode then power on the receiver while holding the bind button, I get a solid green light like I should but my transmitter says “waiting for Rx” and will not show up in betaflight tab either. It could be something very simple as I am new. Let me know if you have any suggestions, thanks!
