Hello Mr./Mrs. Problem solver,
I'm Harshvardhan
recently i had built a race 5inch quad
using OMNIBUS F4 V2 Pro ( https://robu.in/product/omnibus-f4-v2-pro-flight-controller-with-sd-card-slot-bec/ )<distributor in my country
I'm using eachine tx805 VTX ( https://www.banggood.in/Eachine-TX8...-OSD-or-Pitmode-or-Smart-Audio-p-1333984.html ) which supports smart audio
i flashed it and completed the entire build but i cannot see a vtx section or the tab
please help! below is the screenshot of the ports tab and u can see all the tabs except for the Video Transmitter tab even when i enabled expert mode i cant see it. Even the version of betaflight which im currently using is 4.2 above (10.7.1)

Wake up! Time to fly!
Does this omnibus come with a betta control flight? As in controls from the transmitter?


Most modern flight controllers come with a Betaflight .hex configuration file flashed on them. Usually the will specify a different one was used on the sales page for branches of Betaflight like Butterflight and Raceflight.
