hi

I'm wondering about the wiring, as I heard there can be noise from ground loops etc.

power to the git2:
I guess it's best to use the git2 internal battery to avoid noise issues?
If do not use that battery, what's the input voltage trough the av output mini usb cable? Do I need any filters on that input? I have a 3S battery on my quad, an sbec that converts 12V to 5V and a kk 2.1.5 flight controller that can send 5Volts I guess.

video signal
Should I worry about noise on the video signal. As far as I understand, this is mostly a white/yellow copper cable? Should this be shielded or made as short as possible?

Also, how to connect to the transmitter? Can I plug the servo plug into the transmitter, ignoring the dc out red and black slots?
The input does not seem a standard servo plug. What kind of plug is that? I probably have to adapt the AV out cable myself to fit that plug? Can I buy something that is ready made?

So this is the AV out cable:

This is the transmitter:

At least I hope the lag is fine on the git2 for fpv flying.

Thanks!

Please use only 5V input.
The AV out cable pin out is same as Hero3+.
We have't heard noise issues from other users, don't think it is necessary to shield the cable and short it.
