So, I am using Omnibus F4 FC, I soldered and powered up everything, when I connected the receiver, I see the roll and yaw going beserk, without any inputs from transmitter, both those axis keep on, here is the video :

Looks like wrong firmware.

Oh yeah those "omnibus f4" boards from banggood are actually Chinese clones of the original airbot omnibus f4 boards. I actually had one of those catch fire mid air lol.

@aloneseeker yah would suggest double check firmware version like @Dugdog47 said very likely has the wrong target flashed to it and so doesn't have the pins mapped correctly, on newer version of BF after flashing it will ask to apply a config on first reboot of the FC and connection you should tell it Yes apply the board specific config. After that has happened you should be good to configure things.
