First off i'm not a GoPro expert, but i can tell you this.

FPV is not an exact science.I highly recommend you do some research, Watch some how to videos. Then do some more research. After your head starts to hurt, take a break. Then do some more research.

I know i didn't answer your questions, But i've been kinda into FPV a while and there are lots of options out there.This is probably not the best forum for FPV info but i'm sure there are many here that CAN help.

Start here, this guy has some good how to videos.
How to be successful in FPV Part 1 - What is FPV? (3 min 29 sec)



Quote stolen from ^^^^^^^^^^

Quote:
The range equation - Use this equation to estimate how far (in miles) you will be able to achieve:

Range capability in miles = 1/2 + number of hours under the hood/40 + number of study hours/100 + hours spent talking with an experienced FPVer/20

Thus if you have 24 hours of airtime experience under the hood, 50 or so hours of research, and an afternoon talking to a highly experienced FPV pilot, you can expect to be able to make a 2 mile flight successfully.

Have fun in your ventures,

I can start you off with some information, but Tailspin90 is correct in directing you to pre-existing sites with information. A lot of redundant issues get addressed in these threads, when there are entire sites dedicated to providing comprehensive information.

The GoPro2 and the GoPro 3 have different outputs. The 2 version has a 3.5mm composite video output jack. The GoPro3 has HDMI and USB outputs. In addition, some systems like the DJI OSD can use a ribbion cable to connect directly to the GoPro3 rear connector.

You will need a transmitter and a receiver for the video signal. These are available in 900MHz, 1.2 GHz, 1.3 GHz, 2.4 Ghz, and 5.8 GHz. Cheap vs. Expensive are all available.

The Tx module (which) goes into your aircraft, will require one of two inputs: A 2.5 mm composite signal (such as on the RC Logger Tx/Rx combo) or a 3 pin JR/Futaba servo style. (Some even use proprietary input configurations)

Cables are sold for every combination. The GoPro2 is going to be more limited because it's output is composite video signal. The most simple setup for you would be the RC Logger (no, I don't work for the company)

RC Logger's Tx/Rx combo is in 5.8 GHz and comes with 3.5mm and 2.5 mm jacks as well as RCA connectors.

I have made my GoPro2 work with other systems, but soldering and cable fabrication was required.

Once I purchased a GoPro3, my options expanded considerably.

Again, search the web for FPV sites for basic information. Use forums for more advanced or specific questions.

Remember if you are flying something like that, use a quality product. You will want a good high power output video TX. Not for range but link quality, as when you zip around traveling fast you dont want to lose video for 1 sec. As a blanket statement the AMA requires all FPV models travel at or below 70 mph.

Goggles vs LCD is a preference. I prefer goggles because its immersive and I can shut out the world and just fly the model.

I got the Predator V2 kit and that worked just fine for me until I wanted to push past 2.5km. I purchased the Blue Beam Ultra antennas for circular polarization. This allowed me to get a good signal regardless or orientation or movement.

Start with quads.

Easier to fly in FPV. Easier to repair in case of a crash. Cheaper parts.

Go to a site like ReadyMadeRC and purchase one of their beginner packages.

Go with the highest spec 5.8ghz bundle/package you can afford.

Why 5.8ghz? Because this will most likely be legal in your country/state.

Install and fly.

Or the other way to go about it is to buy a phantom quad from DJI - take it out of the box plug in the battery and fly.

The easiest thing for me to fly in FPV was a foam glider. Its already cheap in PNF and crash repair is hot glue. Its great to use to start out with.
