Shopping list for FPV (Please advise)

Hello all,

It's my first try on FPV and after spending a lot of time on reading forums, articles and watching videos, I made the following shopping list:

ImmersionRC 600mW 5.8GHz A/V Transmitter
RMRC-700XV 700TVL ATR CCD Camera
Duo5800 A/V Diversity Receiver
Bluebeam Whip Antenna Set (RHCP)
11 dBi Flat Patch Antenna
EzOSD
FatShark Dominator Goggles

The above setup will go on an F450 quad with Naza GPS.
The quad has stock DJI motors, ESCs, 10" Graupner Props and a 2200 mAh 3S battery.
I'm using a Futaba T8FG Super R/C Transmitter with a Futaba R6208SB Receiver (2.4 GHz).

Now, the questions (stupid one goes first!)
1) Will the Naza GPS work with EzOSD GPS or interfere each other?
2) I will go for 2 batteries setup. One for the quad and another one for the on-board video system. Can I monitor both batteries with EzOSD?

Any other advice will be greatly appreciated.

lets start with your shopping list........ usually the vTx winds up being mounted on it's side, that said your gonna want the right angle connector one like this
http://www.readymaderc.com/store/index.php?main_page=product_info&cPath=11_45_49&products_id=596

on a diversity rx, if your gonna do it, do it right. When you run a bluebeam with a flat patch, be back to talk about that flat patch in a minute, you wind up with this constant switch back and forth between antennas. when it does that, it makes a flicker, totally sucks. The whole idea behind this is to not get flickers, anyways, if your gonna run diversity from a ground station without tracking, get a couple of these
http://www.readymaderc.com/store/index.php?main_page=product_info&cPath=11_45_49&products_id=936
put two of those side by side pointing off 45 degrees from each other and you'll have 90 degrees of field covered. Those antennas got like a 10-15 mile out in front, 2 miles to the side (unmoved) and a mile behind them again, (unmoved). The guy that makes this stuff has ran his like that since he figured em out

OK, RHCP vs flat patch. RHCP stand for right hand circular polarized. The flat patch you selected there is what's known as horizontal or vertical polarized. You want RHCP all around, esp. on 5.8. the two don't work well together and that flat patch won't just flicker through static, it'll just quit in the middle of a flight

question 1, good question. They definatley don't work as a team sending info to each other, but the interferrence thing is a good question

#2, yes it will.

With everything said here, you got everything to fly off into the sunset except a long range system. You'll be fine without it to get going, but to use what you bought, your somewhere between half way there and full blown fpv. for another $300 RMRC has the EZUHF kit, killer little system for the money, miles of range. The ezosd connects to it with a digital plug, shows rssi on both antennas if using a diversity rx, etc really clean EZ setup. Your futaba is gonna go somewhere between 2000 and 3000 feet comftorably. Those distances don't need a patch anything, wouldn't mess with a diversity vrx if wasn't getting the uhf part, the built in rx in the fatsharks and a skew planar on them would be more than enough

no uhf i'd get

The only other advice i can think of is if your an older guy, you might enjoy this better through a monitor. the goggles can be "weird" to some. I put mine in ski goggles and life got alot better (43 yo old guy) but the monitor i fly with is off the hook. they come in 15" to 22", can get without the dvd player, saves a few bucks. As long as a system is outputting static with a chance of coming back, mine has stayed out of black screening and shown everything so far.....

mine is this one
http://www.jr.com/naxa/pe/NAX_NTD2252/

but they go down to like this
http://www.jr.com/category/video-tv/tv/flat-panel-led/n/4294346589/

with that you'd ditch the goggles and 5.8 module for them to get this instead ran off a uno or diversity rx.

the tv works pretty good in sun light, looks like this in use
[video]www.youtube.com/watch?v=BzXQoj4LsJs[/video]
that is immersion 5.8 diversity on cloverleaf and helical on a tracker

I don't own ezosd but alot of people ***** about the sattelite link up taking forever. The have a mod that uses a different sat chip with a battery so it remembers last location like change a battery, links right back up instead of waiting 2-3 minutes each time. Eagle tree OSD pro is instant

Thank you kloner!

As I mentioned in my first post, I'm a newbie. So, for the time being I will not go for long range. Actually, how far can I go with my Futaba 8FG out of the box?
Although, I want to get some equipment which I could use it in the future.
When being more experienced, I could go with a Helical antenna, tracker and the EZUHF kit.

Will I have flickers if I use:
A Cloverleaf Whip Antenna (RHCP) on the vTx
A Skew Planar Wheel Whip Antenna (RHCP) with a 7dBi RHCP Patch Antenna on a diversity vRx?

Thanks again for your time answering me and yes, I had already read the post and the doc file.

Will I have flickers if I use:
A Cloverleaf Whip Antenna (RHCP) on the vTx (right angle one)
A Skew Planar Wheel Whip Antenna (RHCP) with a 7dBi RHCP Patch Antenna on a diversity vRx? YES, on top of that, the patch antenna you selected has a note under it stating it's not truly a CP patch, it is dual polarized, no good. get a uno receiver and a skew planar wheel for now. it'll just reach about what your radio will. The goggle module will almost reach as far but will have more flickers to it. best to run a wire

there are thousands of post at fpv lab about diversity receivers and how to use them, you won't find many people into it that use diversity. better off with one receiver, one antenna and have everything as good as can be. just a 3 lobe clover on the multi and a 4 lobe skew planar on the receiver will get you about a mile to mile and a half all around ya. 5.8 will have flickering when things get between ya like branches, leafs, cars and tree trunks completely block it out

Very nice advice kloner! im doing an fpv setup on my f550 as well. I got a lawmate 1 watt 1.2 tx to start with and a 1 watt 2.4 ghz booster for my spektrum tx. Good for a few miles im hoping, but with naza+gps I should always just return to home if I loose signal anyway.

Hi Kloner,
I have the above setup already purchased and waiting on the TBS Discovery (with Core) to arrive so I can migrate my bits over to the new platform. I *think* they will all fit on the standard F450 frame, but once I saw the TBS Discovery - I ordered it immediately. I have the EzOsd also, but will hold off installing it until I can test it for interference with the NAZA GPS.

I'm flying with a Futaba MZ14 (used with my heli's) converted to 2.4 - so the range of the system, as you stated is safeky 2000 ~ 3000 ft ... maybe a bit more? Anyway, I have two types of questions:
1. Platform Range (motor / battery / esc / prop): I'm flying the standard DJI motor/esc with the Graupner eProp 8.5 on a Hyperion VX-G3 2600 mAh LiPo - flying time is 9:00 flat
Question - even with my helicopters it was difficult to find the 'right' combination (I know that there's a 'witched woman' and some voodoo involved here), but what bits do I need to change to get the maximum flight time? I'm looking at purchasing ~5000 mAh LiPo's, but am not convinced that battery capacity alone will really get me the longer flight times that I think I need. I guess the point here is that it doesn't seem to me to matter so much if I get the longest range setup for my Vtx/rx if a. the radio doesn't have the range and b. the platform (motor/battery/esc/prop) can't go that flight distance/stay in the air longer than 9 minutes.

2. Vtx/rx: with the FatShark's, I've played around with them (not on the MR) and had some fun and after the initial adjustment (I'm 53) when I first put them on, haven't found them to be "too difficult" to use. I like the monitor setup that you have but it's more "stuff" that I have to carry with me, so I haven't chosen to go that route (yet?).
Question:
a. will the two http://www.readymaderc.com/store/ind...roducts_id=936 antennas provide more clarity at closer range - not just distance?
b. can they be hooked up to the FatShark?
I have a wooded area that has a stream running through it that I am "itching to explore' with the MR so I want to prioritize "signal clarity" over a (relatively) short distance as I will be basically stationary vs longer distance anyway.

Thanks for this. I've found your post and the suggested fpvlab doc very informative.

Dale.

Very informative thread, thank you very much for the info Kloner. I also plan to equip my F550 for FPV in the near future. I already own a GoPro Hero 2 attached to an Aeroxcraft gimbal. Three questions:

Would you recommend the GoPro as an FPV camera?
Will EzOSD work with the GoPro?
The Cloverleaf antenna from your wish list would be for the TX of for the Fat Shark goggles?


Thanks,

Javier

1.I've had really good luck with my hero2 on the system

2.yes it will

3.the goggle would use the receiver version clover leaf, for that you want a four lobe one, newer goggles want the 90 degree ends. older versions need the straight one. They moved the antenna port from the top to the front. I really really liked using a directional 5.8 on my goggles this weekend. used my head as a tracker and i really really like the reception on a small patch like that versus the clover or in my case, skew planar. Those just aget a little more rejection, doesn't cover as far and the patch has a lot better penetration, makes 5.8 almost bearable
