I currently have the DJI Avata 1 with the goggles 2 and the FPV controller 2. I am wanting to purchase a custom built drone that will work with my DJI equipment, newbie here so any and all suggestions are welcome.

I know I can use the 03 system but what do I choose as far as pnp or elrs? What will and won’t work out of the box? Thank you
