First FPV Quad

Hey All,

I would like to build a cheap but good FPV quad. I don't know much of anything about quads. I looked at the Low Cost Mini Quad build videos with the ZMR 250, and I'm sold on that unless there's something better. I'm almost ready to start ordering parts and trying to get this thing together, but the video doesn't mention FPV gear or radio transmitters. I don't have any RC stuff, but I do have access to a great workshop and lots of nuts, bolts, wire, and electrical bits. I'll need to get some sort of FPV goggles or a screen, as well as the radio controller (or whatever it's called—the thing with the thumbsticks that I'll use to control the quad.)

Is that low cost ZMR 250 build the best? (
) Are there slight build modifications that are reccomended?

Also, I don't understand how all the hardware works. Is there somewhere an article or video which explains the basics of ESCs and the compatibility of different recievers and things, firmware, software, etc.?

I want cheap, but not so cheap that it's trash, and am willing to figure out firmware and software stuff as long as I'm not having to do something like write my own code.
 
It looks like it should be relatively straight forward.. Just solder and bolt everything together like:

I'm sure if one was to follow the tutorial video they'd get a good quad, but there are a couple things missing from the video. I don't know what type of battery to get. I'd like to have something that lets me fly for as long as possible. I also need a Radio Transmitter and FPV stuff, as I mentioned already.
 
So, it seems, for the DYS BE1806 2300kV motors, that I'll want a 3S LiPo battery. I don't know how much mAH I need to get a good flight time, also I'll need a charger. The Naze 32 has voltage monitoring, which seems to be a good thing. Presumably I'll need compatible radio gear so that I can see my battery level on the Radio Controller.
 
So I did a web chat with some guy from HobbyKing and got some reccomendations for a Battery, Charger, and Radio Transmitter/Reciever.

For battery he reccomended a 2S or 3S 1300mAh. (Although now that I'm looking at them, they all have 'C' values, and I don't know which I should pick.)

For a charger he reccomended either of these:

http://hobbyking.com/hobbyking/store/__58314__Turnigy_P403_LiPoly_LiFe_AC_DC_Battery_Charger.html

And for a cheap radio he suggested this:

So, the motors have a max current of 8A, which multiplied by four is 32A. So, for a 1500mAh battery I need >21.3C, so I'm planning on getting a 1500mAh 3S 25C battery.
 
Sorry, I glanced at your post and saw all of the replies I assumed someone was following your thread. Anyways, the Turnigy 9x is a great radio if you want the most band for your buck. The Turnigy battery charger you sent looks great, I'd get that one even if it is a little more. If you get the quantum goggles definitely get the combo, I have tried to make it cheaper by making my own parts, and it is nearly impossible to beat that price.

Mutistar batteries are usually a little lighter than other batteries and they are made by Turnigy specifically for muti-rotors.
