Do FrSky Omnibus Boards run the 'regular' Omnibus Ardupilot firmware?

Hey, I’m not sure which tags should be used for this question.
Our use case is a quad copter, hence the ArduCopter tag.

We’re looking into purchasing one of these FrSky FC.
Specifically, one of these two:

  • R9 MM-FC (OMNIBUS F4 V6)
  • R9 MM-FC (OMNINXT F7) (probably the better choice)

I was wondering if the Ardupilot FW for ‘normal’ Omnibus flight controllers should work, or we’ll need to re-build the code for these controllers.

Anyone has experience with these?
