I'm Tom, from Erie, Colorado. A small town north of Denver along the front range of the Rocky mountains.

In some form or another I have been involved with flying models for 51 years now. From putting together little balsa kits together to 1/3rd scale planes, to helicopters and now multi-copters for fpv/aireal photography.

I'm getting ramped up to build my next project, fully immersing myself into fpv.

Here's the plan.

XAircraft Hexa frame
DJI WKM for control
tm2216-900kv motors
tm 30a esc's
mc6500pro camera mount
Foxtech AIO goggles
Haier 7" monitor, on a tripod
Foxtech 5.8ghz 500mw vtx
Foxtech pocket reciever mounted to the tripod for the monitor
GoPro H2
IBCrazy cloverleaf antenna's

Haven't decided on the fpv camera yet.
What I would like to do, before I decide, is to hook up the GP to live feed and see how it would look as a fpv camera.
Tried a test yesterday, but was unsuccessful, not to sure on the cable pin out, or how to do this, really.

I'm assuming I use the TV composit out?
The pin out on the composit connector, from the tip to the cable meters out as;
1 = red wire
2 = white wire
3 = yellow wire
4 = ground

At the tx connector end, I arranged the pins by color to match the 1/2 cable supplied with the tx, right to left;
ground, power, video, audio

Not positive on the cable pin out, and this is where I can use some help?

Read smewhere the the camera needs 5v, so I installed a bec on the battery for this, but think that is mt second mistake, as the tx needs at least 7v.
As I see it, my options are to either remove the red wire and let the battery on the GP do it's thing, or install the bec to the red wire to feed power to the tx?

Want to figure this all out before the frame shows up next week. See what the GP looks like on the monitor and goggles first to decide if I want to use it for fpv or a dedicated camera like the Sony 700.

Also, curious what others are using for fpv cameras?

Any help here would be appreciated, don't want to burn up the GP upon powering it hooked up!

Most people here don't use the gopro's live out to fly fpv for several reasons, but the main reason is it doesn't expose dark areas very well. Best to use a separate standard def security camera. Personally I like the $26 one from securitycamera2000.com (I have 2) but really any will do.

Welcome to FPVLAB!

You can run the vtx off the battery's 12v with a filter or something and just hook the ground and signal wires up to the camera. Then take the BEC + line and hook that up to the camera and terminate the ground, you don't need it.

Welcome! Lots of us FPVers in Colorado!

Thanks guys! Found the problem, thanks to the vid.
The video cable is the one next to the ground, the wire color is red. Once I re-pinned the connector it came on line.
It was midnight, only the tv and one lamp on, so not much light. Going to retest it again and select the best channel on the tx/rx for reception.

Under the goggles, I was quite pleased. I had read that the GP live feed was 16:9 display and black bars top and bottom, limiting the display. Confirmed it does, however, it's really minor and looks to be quite viewable really.

Will give it a good going over today and then decide if this is what I want for fpv or not.

Appreciate the help.

FWIW this is a GoPro FPV video feed from my X8 project:
