So as over the year have built up my kwad myself,friend alway seem to help with the Pc config stuff,but he's not about anymore so need to start learning so here goes...
Soldering a vtx in the picture I have green and white left.
Do I solder the white to tx 6
And use smartaudio or config it in crossfire am abit confused?
Can I cut the green off, someone needs to help with what smartaudio does?

Thanks in advance

Can't get picture up?!

Thanks will but a picture up just realised the white wire is going to crossfire Rx am I right

Here is the picture hopefully

You sure that's wired up right? It looks like things are wired in the following configuration assuming this is a Kakute H7.
FC       -> VTX
Vid out -> Bat
Bat      -> Gnd
Gnd     -> Vid in

Just the 3 wire on a f7 FC
Red to battery positive 
Yellow to VO video output
And black to GND.

Alright, that makes a large difference. Without the flight controller model listed, I had to guess. Looks extremely similar to the one I'm using.

But yeah, if you plan to use SA, you can simply remove the green wire. Just pop the white wire onto a free UART TX pad and set that as VTX (TBS SmartAudio). The green and white are used if you wire directly to a TBS RX module. Voltage range is 6-25 volts, so 2-6S, which that pad should supply.

Thanks very helpful ? Now onto the crossfire Rx that should be alot easier to solder/wire up.

Hope you have success! In my opinion, that's the best 5.8GHz analog VTX, and the best proprietary control link. Should serve you very well!

Do let me know if you have troubles getting the VTX unlocked for full power. That info is strangely uncommon, despite being a requirement to get the most out of the device.
