Flipping the sensor 180⁰

[Roman Simon]

On my Raven I have an option to flip the sensor, but on my Weapon Helium it's not there.

How can I flip the sensor to mount the camera upside down?

I don't believe you can do it in camera any more, so you'll probably need to do it in post (and rely on a monitor flip function to monitor on set).

Per Red, it's only avail on the Epic Dragon or Scarlet Dragon:

Sensor (Flip/Mirror Scan Direction)

And Reddit seems to agree that it's missing from later firmware:
