Baby Nazgul 73mm binding issue.

[Tech5960]

I bought a Baby Nazgul 73 mm and i tried binding it with my Taranis QX7 ACCST thru Betaflight and the quad will not arm and the receiver tab shows my quad spinning. I can sure use some help as i have a feeling the frsky D8 receiver in the Nazgul is not matching the ACCST qx7 so i don't know what to do?

I am in the same boat. Did you get an solution. I even have the 4in1 moduel on the back , and I still can't bind the same drone as you.
I have a feeling that it is something like the firmware doesn't match or something like that . But I have no idea how to check
