Please take a look at my post above and tell me if you know what is the distances with each TX!
It really doesn't matter between 200mW and 800mW(which is probably
500mW), i'd tell you to get a 200mW because its half the price and won't be
such an overheating module, but really it's not that big of a deal. Those are
fine powers to have. It's the 1W and 2W people that are really asking to get
spanked.

Depending on your "list" that I should take and be simple, the only extra that I have is the OSD. Maybe the Video TX is big
but ok I might take the one with less power. Antennas are needed to get the best signal.. first flights in FPV and bad video
signal is big problem... So a video recorder and video splitter are not that much. Pan/Tilt will be used in the future but the
Mount is really good and I will use it only to set the Camera in it. Except the TX and OSD what else I have more than I need
in this list? Thank you very much for your interest and for your help. I really appreciate it!

Yes you could start with that stuff but nobody can tell you what your range will be... could be 20 miles, could be 20 feet. I don't know much about using 5.8

I wouldn't try 5.8 ghz as a beginner. It's basically unusable unless you buy CP
antennas for it. Try 900 mhz or 1.3ghz, even 2.4ghz. You also don't need pan
or tilt starting out, that will just complicate your flying. And you should check
out the AIPTEK MVPR+ 3MP recorder. It's $40 and is one of the best recorders
out there.

Hello and thanks for replying. My Radio is in 2.4GHz, Can I use the 1.2-1.3GHz Video TX? Many said that is not working so good...

This is a video camera recorder? It costs 100USD, I have the wrong item in mind?

If I will use 5.8GHz I have already have in mind the CP Antennas. By using 1.3GHz, isn't Antenna Tracker needed
for the ground station? Whats the difference with 1.2GHz? Will I have any Problems with my 2.4GHz radio?
Or with Cellular network or something?

Don't know where your at (no location listed) so cant say on the cell phone thing. Do a search and see what freq they use in your country. In the states, 1280 works great.

That's fine if you were planning on using CP for 5.8ghz already, I was just
reminding you that it only works well with CP so linear isn't really an option.

You need to look into your countries frequency allocation chart and find if
you can broadcast on those frequencies and what licensing is required. You
don't need an antenna tracker for 1.3 ghz, you can use omni antennas like
any other frequency. There is no real difference between 1.2 and 1.3 ghz,
they all (normally) refer to the 1280mhz band. If you're using a 2.4 ghz radio
you are going to run into problems trying to FPV with it, especially spectrum.

Nevermind, actually they appear to have gone out of stock indefinitely.

I would look here though at what other ground recorders are good.

It is worth taking a buddy for "joyflights" while you fly line-of sight until you are VERY confident with the set-up and balance. Have them read off what they see in you OSD if you have one.. Mark in the battery/electrics bay exactly where the component sit, including the exact battery so you don't have CG changes to wrestle with.

That way you get to know what range you have before picture fuzzes, you know if the picture improves or worsens as you turn for home and all the other things that cause sphinctal cringing when you just start out.

Nothing seems to move that fast when you fly FPV.....until it all goes wrong !

Okay, rather dumb question. Just got my FPV system from BevRC, and I'll be wiring it up over the next week or so. Now that I have it, I notice nothing has labels showing the polarity of the power hookups it needs. It's all 12V DC with standard barrel plugs, but the power receptacles on the VTX and VRX aren't labeled with polarity. Should I just use the standard of positive on the center pin and negative on the outer part? I'm also not sure how to tell which wire goes to which on the bare ended pigtail cables I got to solder battery connectors on. One wire is completely black, and the other has gray dashes on it. Which one of those goes to the center pin and which to the outer part? Hopefully there's a standard way to do this, as the last thing I want is to do this wrong so I immediately fry everything as soon as I plug it in.

I live in Greece, and from what I know 900MHz and 1800 Is for the Cellular network. Why 2.4GHz for my radio is a problem? I have Futaba 7C.
Why I cant use 5.8GHz and I have to choose 1.3GHz?

Okay I figured out that the VTX, VRX, and camera all have polarity with center pin positive. Just had to try it and hope it works. Still not sure about soldering the power cable that came with it (I tested the video system using other power adapters), but I read elsewhere the wire with a white stripe usually is positive so I'll assume that goes to the center pin. I'd test it with the multimeter I bought, but the thing doesn't appear to work.

So anyway, new question. I tested the video system and it worked, but any sudden movement of the camera (especially that caused exposure to change from light to dark) or moving the VTX much caused my screen (a Coby DVD player with video-in) to go black and hunt for a signal. So I'm assuming this is the "black screen of death" problem people have talked about. The guide on the first page of this thread talked a little about solving the black screen issue, but not in enough detail to be helpful. Can anyone give tips on how to prevent the screen from blacking?
