Iflight chimera 7

Hi new here please forgive my lack of knowledge with forums !
I have little experience had dji mavic pro but wanted to fly fpv .
I live up a mountain in Wales want to fly with insta cam on board so went with 7 inch iflight 6s using cross fire nano receiver
And jumper t18 radio . Dji air unit
Do I need to turn off dji air unit receiver or do I just bind with Cross fire
Hope that makes sense

nope got same setup myself ( you carnt turn off anyway) just dont solder the yellow ish(orange) wire to anywhere. just fit crossfire nano and bind as normal.
