I am using BF 4.4.3 VTX presets with Rush Tiny Tank and OSD shows R8 but practically the signal is only on F7 , no matter what I do. I tried MSP with Display port as well as  Smart Audio in Ports tab.

Sounds like the VTX Table is incorrect. Change the VTX to match the table below. There are a bunch of pre-set table in the GUI. Otherwise you just have to manually enter it. 

It sounds like the ELRS transmitter controls the video transmitter.

Still the same , VTX is F7, and OSD shows R8. The table is updated

OK, I don't think you have VTX control properly setup.

Let's check your wiring. Photos of your wiring from VTX to FC. Post dump file.

And what radio controller do you have?

I have RM Zorro, see wiring and cli dump below.

Hi niuk,

Try to confirm the pulldown options in your BTFL VTX preset. The "show CLI" table for TinyTank does not have Lowrace available, thus only 5 bands in the CLI.
The diff you posted might be for one of the Race Tank versions. I could only verify that none of the reviews or sales literature describes the lowband feature but it is "greyed-out" as available on request.

Might be worth a shot??

Again. Dump file. Not diff.

Photo of how you wire, not a diagram from the manufacturer. Trying to figure out whether you did something wrong.

These are not vendor pictures, I wish there was one. I took it from the build, was not easy to find out

I just want to see photos of the wires going from the VTX to the FC. I don't need to photoshop and diagram it.
