To those who have lots of FPV experience, which is the best frame recommended?

secondly, to have a good FPV system, please recommend:
  1. Motors
  2. Props
  3. ESC
  4. Video Transmitter
  5. Video Camera
  6. TX Antenna
  7. Receiver side
  8. Goggle

And anything else needed.
Thanks!

Frame: hoverthings.com has 2 versions available. One was released early last year, and the newer version a few weeks ago. 

Motors: Avroto and RCTiger are good. Depending on build weight, flying style, etc. you can look at 700 to about 1000 kv. Check out Clubheli.com and MontoRC.com. 

Props: GemFan carbon-filled nylon are nice.

ESC: Simonk-flashed ESCs are getting good reviews. ZTW's are available pre-flashed at http://www.shop.aglhobbiesllc.com/Mo...SC-SimonK.html

For video, check readymaderc.com...excellent support and selection. Much will depend on things like the distance you intend to fly, the terrain (open space, vs forest), etc.

Thanks. can you elaborate what's the purpose of selecting lower KV when it comes to certain style of flying? In fact I see the lower the KV, thed more expensive the motors are. What's the relation?

You should look into the TBS Discover frame as well, they have a lot of FPV videos up and a great frame.

Generally you can get better efficiency with larger props moving at slower speeds...

There isnt really one perfect setup, it all comes down to research!! Check out others builds forums posts, ect. I myself spent almost 1.5-2 years researching and gathering parts (slightly because quads arent cheap) Also your equipment kinda matters on your budget, you could spend a few hundred to thousands on a FPV Quadcopter, depends on what you want to use it for. Again research.

If you want you can check out my current build:

Thanks! Yes, I've been in contact with Raphael.

Is it better to go with quad or Hexa for FPV?

Also need to consider the flight controller, too. Some choices are based on MultiWii (Quadrino board and others), Naza, and OpenPilot CopterControl (original CC and new CC3D). All have good support and user-base.

One other place to check out is http://www.openpilot.org, which supports the CC and CC3D. Quite a few FPV'ers there.

I'd say tri or quad. Less motors = more flight time. More motors = more lifting power.

Most cases with fpv you want to maximize your flight time.

I have a tricopter with 600kv tiger motors and 14" props. I can lift a t3i and still get 10 minute flights.

As far as a camera for fpv, I'd say go with a GoPro. It offers the ability to record decent quality video of your flight at the same time as giving you a video feed for flying. The GP2 would be fine if you can't afford a 3.

One trick I've learned is to power the gopro off of one of your ESCs bec. Create a cable that goes from the ground and power of the bec to a USB connector, and you can power the gopro that way and not have to ever worry about its battery dying on you.

Depends on the flying style want and how much wight you want to carry. If your just doing a small FPV camera or GoPro stick with a quadcopter, if you want to carry something heavy in addition to FPV like a DSLR camera you will need more propellers for more lift.

The more propellers you have the more stability and lift capacity but your also looking at more power consumption more to configure and troubleshoot ect. Also quads look a little more nimbull than hexa's.

If this is your first build I would say stick with a quad, look around at quads that have a proven success and model those. Think about your budget how far you want to fly ect. Calculate your estimated total weight based on the equipment you want to carry then look for a motor/prop combo that will give you a good efficiency for your weight, there are a number of forum posts and articles that you can find and use to help figure out what would be a good power setup based on your weight.

NICE!

Also FoxtechFpv.com now has a gopro 3 FPV adapter with power on it.

Basically, lower Kv motors would be used with larger props. A 770 Kv Avroto on 3S is optimal with a12x3.8 APC slow-flyer. Lots of thrust to lift a large load. A 900 Kv RCTiger works well with 10 or 9 inch props, is better suited for a lighter build, but would be a bit more "sporty". Even more so as the build gets lighter and higher Kv motors are used (1100 Kv with 8 or 9 inch props).

To get an idea of power requirements, prop size, thrust and motor, check out my blog. I did some static thrust tests with different props on the Avroto 770 Kv and RCTiger 900 Kv motors. While the motor selection is limited to those I use, I was able to look at a few different props.
