Hello all,

I’m new to the flight community, and started my first build with an fpv 5inch quad. I have been struggling to bind my transmitter and receiver and would love another set of eyes on what I’m doing. I have the taranis qx7 access transmitter, a speedybee f405 fc, and the frsky R-XSR. I watched some videos and read some forums, updated the firmware on the qx7 (2.3.15-otx) and on the receiver ( and am using the proper D16 mode to bind but the receiver and transmitter still won’t bind… anyone have an ideas?

… anyone have an ideas?
FrSky has a bunch of firmware versions for different parts of the world & different sub protocols, both the Tx & Rx MUST be using the same.

Here is a video that explains.
