FPV Beginners Reference Mega Thread...

well with wallet wide open, i've made the plunge into fpv by ordering a pair of fat shark aviation goggles.

i've scanned through many threads and am a little frustrated how spread out the information is and i'm hoping this thread will be more of an opinions/review of your experiences with various components for FPV.

to begin with can people list what they started with and what the pro's and con's of those setups were, then what they recommend upgrading to?

Frequencies:
It is my understanding that 1.2G is legal in the USA but requires a license. See http://www.scribd.com/doc/4549372/p...d-amateur-radio for details.

Legal bands (some power restrictions at some frequencies). Note that the ends are off limits because it spreads over a range so 1.240G would actually spread from maybe 1.238 to 1.242.
902-928mhz
1240-1300mhz

Some places call 1.2G the range from say 1.1 up to 1.2 and the they call 1.3G the range from 1.2 up to 1.3, so 1.3 is the range that you want from them.

ARRL further specifies (strongly suggests, but may not be a legal requirement???) that you only use these for "amateur television":
909-915
921-927
1240-1246
1252-1258
1276-1282

This is for USA.

So for goggles most of the threads recommend the fat shark aviators or headplay. it seems headplay is though that have better picture quality, color range but the fat shark has a wider field of view (FOV). headplay seems to be tolerable for some who wear glasses but most people say the fat sharks wont work with glasses (which i do), so it looks like i'll be getting contacts.

i ordered my fatsharks from http://www.readymaderc.com
shipping prices were cheap but from the threads and their page it looks like the owner may be backlogged. hopefully they will ship quickly.

here were some good reference threads with peoples opinions about goggles:

UPDATE:
i forgot to mention how quickly they shipped the fatsharks. i ordered them one evening and they were in the mail the next morning.

REFERENCE:
fatshark data sheet: http://www.gowiththeshark.com/RCV922_spec_A.htm
receiver frequencies:
#1 2414 MHz
#2 2432 MHz
#3 2450 MHz
#4 2468 MHz

Headplay supports 720P (depending on input source - far more than needed for FPV) and with the HPPCS50 discount/promo code, costs US$361.3 shipped (no taxes included) in the US (US$399.95 without discount and shipping) from headplay.com. That is far lower than the US$495 you mentioned.

That sucks that the Headplays are cheaper than Fatsharks. I wish this deal was around 2 months ago... DA*M

thanks for the info aa78. that definately makes the headplays more attractive with the lower cost.

i kept going back and forth between the two.... from the other threads it looks like it came down to this:

fat shark: larger field of view, better fit, better connectors, but worse resolution/color, less connectivity

head play: smaller field of view & flimsy connector & more ambient light & and external computer module but higher resolution and better connectivity for non FPV uses.

one other issue that may be a big one for me is the fat sharks aren't supposed to work well with glasses while some have had success with the head play.

Even though you may feel the need to scimp out on certain things you shouldnt. If you do make big purchases like goggles and rX/Tx you might as well go all the way and get quality stuff. There are some many compnents to this little project and all it take is one to fail to send the whole thing crashing down.

Something interesting from the HeadPlay forums: http://www.headplay.com/forum/index.php?topic=459.0

They are planning the next generation of the goggles with HDMI inputs so they will most likely resolve the other issues too.

RC_Ron: No particular advice except to read the stuff posted here on these forums. There is a ton of information and I am still going through it bit by bit. I haven't transitioned to FPV yet but fully intend to do so. I believe there are many more people here who have far more knowledge and are far better capable of advising and helping you.

What I have preliminarily decided is to get the 900MHz 500mW Pro Series video transmitter and standard video receivers (qty 2) from DPCAV (one with a 8dBi patch and one with a 3dBi dipole), DX201 or KX-191 camera (I strongly suspect KX-191 to be a Telepix board camera) and Headplay goggles. Tx/Rx for controlling the airplane will be 72MHz. OSD and other stuff should come later once one has mastered normal FPV flying. Eagletree has a very capable OSD (Pro version) and when combined with the upcoming Eagle Eyes, it would be an even more capable FPV platform:

There are separate threads in this forum for both; OSD Pro and Eagle Eyes. Other options for OSD are RVOSD and eZOSD among still many other DIY ones.

So that a beginner won't get frustrated or disappointed, I would delete anything made by intelligent flight and refrain from making any reference to their store. Mark Harris is the manager and the last time he ever posted anything here is June 29. There have been some complaints about service, mainly people sending their money to them and receiving nothing.

Unless someone from intelligent flight would care to resurface and respond now.

Newbie should buy one of those combo set that includes everything for around $500. Once you have tried the basic gears, everything in the forum will begin to make sense.

Here are the pitfalls I fell into as I started fpv:

1) I started with a 900mhz 500mw video transmitter and an 8dbi patch from rangevideo. Flew it for a while, up close it had a noise free picture. At 1.5 miles it got kinda fuzzy and at 2+ miles it wasn't fun to look at anymore. Then I tried a 2.4 ghz 1 watt transmitter with 14dbi patch. Man what a difference. I've been way further out and still had good clear video. Wish I had the 2.4ghz first. But now that I remember I wanted to use my 2.4ghz FASST system as the control, but soon upgraded to the Scherrer LRS and so that problem was solved.

2) Recording the flights, at first I was using a set-top dvr recorder which worked but wasn't convenient. Then came the handheld hard drive recorders, it worked, but I just wasn't satisfied with the quality. Finally I found a hard drive based sony handycam with av inputs, and this is what I use now.

3) Cameras, not knowing any better I started with a kx171, and thought it had a great picture until I started seeing videos with more color and contrast. Then I bought a dpc-480a, a 100% improvement, it'll take an upgrade to HD to get me to change cameras again.

4) I use a Sr. Telemaster for fpv, so the power requirements are not only different but greater. I use the A123 cells and have played with different arrangements and methods of charging them. I have several "packs" that I can use or combine together to make a long flight pack. I have always had my fpv power separate from the motor and esc power so I haven't had any interference issues.

5) Goggles, don't buy the r-vision goggles, they have a good picture, but they will break at the hinge, mine did, no warranty support. Then I went with headplay.

6) OSD, I almost made a fatal mistake last year when two osd's were due to come out. When Eagletree gets their ground tracking station developed, their entire osd pro system will be the thing to get.

thanks for the input carlyle. i came across that camera but hadn't seen any comments on it, plus it was a little pricey. i may have to look it up again because i have yet to buy a camera.

i was just reviewing headtracking systems and decided to go with the DT-3K Damntronics/Flytron head tracker. http://www.rcgroups.com/forums/showt...ighlight=dt+3k

it is cheaper than the magtrak2 and trackr2 and judging from comments seems to work well. i got it for $96 at flytron http://www.flytron.com/21-dt-3k-hybr...nsmitters.html and it comes with a hitec plug.
