Hi everybody,
After several hours of research i decided to post here...
I try to bind my BetaFPV Cetus (and manual...) with my Taranis X9 Lite (with XJT Lite D8 external module)... but without succces ! 
Here the FC off my drone : 

• Flight controller: Lite 1S Pro brushed FC
  

and the original transmitter in the pack :

• LiteRadio2 SE Transmitter (Frsky D8 Protocol)
  

When the drone is in binding mode (green led flashing) and i select "bin d" on my Taranis... nothing's happen ! 

Here are the settings on my Taranis External RF) :

• mode : XJT Lite D8 module
  
• Ch. Range : CH1-8
  

Thank's for helping.
Regards.

Yvan

How are you getting the quad into bind mode?

Plug in quad. Wait for complete boot up, then push the bind button?

Hi,
Thanks for reply.
I did exactly like you said... But is not working... ?

Try updating the external module. I assume you don't have another quad.

Hi,
Thanks for reply.
No... i don't have another quad... and it seems is not possible to update...

Yes, you can update the XJT lite module. Actually more accurately downgrade, in your case. I think I know the problem. Your XJT module probably comes with 2.x firmware which will not work with third party D8 receiver. Go to link below and download the pre-2.x.x firmware and flash it to the XJT.
