yoodoo Posted August 30, 2014 Share Posted August 30, 2014 Can anyone advise on a cheap FPV set up? Not knowing a great deal about this I have looked on HK site and it's a little confusing to me. What do I need? I just wanted to shop at HK or Banggood..not interested in the high end market. Thanks. Also what is 500mw 5.8Ghz etc and the range needs to be about a mile.

smeghead28 Posted August 30, 2014 Share Posted August 30, 2014 (edited) Okay,straight off it is worth bearing in mind that the limit of transmission on the 5.8ghz band is 25mw,anything over that is technically illegal although most people use more than that. It depends what you want to do exactly,personally I dont find the idea of wearing the goggles a very good idea as most of the time I fly alone so I have no idea if someone is about to walk up behind me and bonk me on the head and pinch my stuff! In its most simple form you need a video transmitter along with a camera on the vehicle, On the other end you need video receiver along with a monitor of some kind to see the image on,such as the mentioned goggles or a separate screen. Bear in mind that both of these also need their own power supply. Most of the stuff runs on anything from 6-25v so a 3S lipo or similar could be used to power it. You can also get a small circuit board that you plug the lipo balance lead into that gives you a stable power supply for the transmitter end. Most popular stuff is made by Immersion RC and Fatshark. if you look at this it gives you an idea of some of the parts involved. http://www.troybuiltmodels.com/ns/images/items/FSPREDATORV2.jpg In that case the goggles have the receiver part built into them.

smeghead28 Posted August 30, 2014 Share Posted August 30, 2014 (edited) Couple of mine Gopro is used for the FPV picture and also for recording at the same time. The board behind it is the transmitter,it is powered from the lipo in the Phantom and is fed video from the Gopro. On the other end. Silver box is the receiver and it is stuck to the back of the monitor that is mounted to the transmitter. Both are powered by a single 7.4v 2S 1000mah lipo The view I get. It is worth noting the battery percentage in the top left. If you are going to fly a long way off it is worth knowing how much battery you have left. That information is overlaid from a separate box in the Phantom,it also shows distance,height etc. You don't have to use the Gopro,you can get a smaller,cheaper camera to get a FPV view.

yoodoo Posted August 30, 2014 Author Share Posted August 30, 2014 Great,thanks. I dont want the goggles, as you said it a security thing with mCan the go pro be used as a FPV camera or do I need a separate one? Do you have any links to this gear? Thanks Quote Link to comment Share on other sites More sharing options...
smeghead28 Posted August 30, 2014 Share Posted August 30, 2014 Gopro can be used as a FPV camera. Mine is a Gopro Hero +3 I got a USB lead plugged in the side of it that feeds video to the transmitter. http://www.ebay.co.uk/itm/281299818844?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT You could transmit sound as well if you wanted to. Bear in mind there are also different USB leads for different Gopro versions,some will also supply power to the Gopro with certain models but you cant do that with the Hero +3 I got my stuff from all over the place but will provide some links Monitor https://www.rcgeeks.co.uk/equipment/first-person-view/lilliput-fpv-high-resolution-7-lcd-monitor.html Transmitter (which is technically illegal) https://www.rcgeeks.co.uk/equipment/first-person-view/fatshark-250mw-5-8ghz-fpv-transmitter.html Receiver http://droneflight.co.uk/products/immersionrc-uno5800-single-90dbm-receiver?utm_source=googlepla&utm_medium=cpc&gclid=CJSolKOWu8ACFazItAodYlkA2g Fatshark and Immersion RC is cross compatible and the transmitters use the same wiring layout. Also I have hacked around leads quite a lot to get it all to fit behind the transmitter which includes hacking into the wiring coming out of the monitor which couldn't easily be fixed if you got it wrong Quote Link to comment Share on other sites More sharing options...
yoodoo Posted August 30, 2014 Author Share Posted August 30, 2014 Top man,Cheers mate..I'll look into all this now I have a good idea. So if I get a 500mw transmitter that would be a good,strong signal? Quote Link to comment Share on other sites More sharing options...
smeghead28 Posted August 30, 2014 Share Posted August 30, 2014 Top man,Cheers mate..I'll look into all this now I have a good idea. So if I get a 500mw transmitter that would be a good,strong signal? Yes but bear in mind it is illegal Also when the signal is in the air as it were it travels a lot better than on the ground where you need constant line of sight,therefore you can get away with less power in the air. The supplied stock aerials work okay but something like this works better apparently. http://www.quadcopters.co.uk/immersion-rc-fatshark-58ghz-antenna-set-v2-464-p.asp I haven't had my set up going in its current form yet other than just turning it on in the house Quote Link to comment Share on other sites More sharing options...

smeghead28 Posted August 30, 2014 Share Posted August 30, 2014 Also be sure that the aerial is always in place when you turn the video transmitter on. Leaving it off can cause it to fail. I have forgot to put it on once and noticed within a second or so and it was fine so it doesn't just fail instantly if you forget. Quote Link to comment Share on other sites More sharing options...

turok007 Posted September 13, 2014 Share Posted September 13, 2014 the 900mhz is against the law in the UK so never post a video of yourself using it. lol or mention it again ever. but everything else looks good. Quote Link to comment Share on other sites More sharing options...
smeghead28 Posted September 13, 2014 Share Posted September 13, 2014 900mhz band is a no no for transmitting on http://www.fpvuk.org/things-explained/video-frequencies-for-fpv/ Quote Link to comment Share on other sites More sharing options...
yoodoo Posted September 13, 2014 Author Share Posted September 13, 2014 But it would work if you were say...abroad with the specified equipment? So what would give a good range and a clear picture the is UK legal? Thanks. Quote Link to comment Share on other sites More sharing options...
yoodoo Posted September 13, 2014 Author Share Posted September 13, 2014 Also they say the MOBIUS would give "Live feed out" I take it this means you can FPV from the Mobius? Quote Link to comment Share on other sites More sharing options...
smeghead28 Posted September 13, 2014 Share Posted September 13, 2014 Well based on the link I put we are technically limited to 5.8ghz for various reasons. I wouldn't use 2.4ghz. My mates Phantom 2 uses Wifi on 2.4ghz and my radio gear transmits on 2.4ghz and we do get some cross interference so there is a chance you would get the same. 5.8ghz has proved reliable depending how far you want to go and if you can maintain line of sight. The ariels play a big part in this as well,the stock stick ones work okay but better range can be had some cloverleaf types. At the moment I am only using 25mw and can get a good 200metres with no issues. I am a bit afraid to go much further away,I still like to be able to see the quad Quote Link to comment Share on other sites More sharing options...
smeghead28 Posted September 13, 2014 Share Posted September 13, 2014 Also they say the MOBIUS would give "Live feed out" I take it this means you can FPV from the Mobius? I would assume that to be the case by the look of the description. Quote Link to comment Share on other sites More sharing options...
turok007 Posted September 13, 2014 Share Posted September 13, 2014 as smeghead28 just said 25mw is the law. also in the UK you need a spotter. so you cannot fly to far anyway. in the USA they have systems that go for miles. well at the moment they do . lol Quote Link to comment Share on other sites More sharing options...

turok007 Posted September 13, 2014 Share Posted September 13, 2014 (edited) how far can you get with the 25mw also in the UK a major FPV shop says anything under 600 is legal. lol Edited September 13, 2014 by turok007 Quote Link to comment Share on other sites More sharing options...
yoodoo Posted September 13, 2014 Author Share Posted September 13, 2014 Great post on the frequencies.I appreciate the help you are giving me as I really do have no clue,just what other members put up.Also....(you see,there is more ha ha) I was going to go for a head tracker so I can lock GPS and use the tracker.Can you fellas advise me on that too.All this has to be compatible with the NAZA V2 as well. Gracias seniors. Quote Link to comment Share on other sites More sharing options...
smeghead28 Posted September 13, 2014 Share Posted September 13, 2014 how far can you get with the 25mw As I said further than I like to fly. I can get about 200m away but by then the quad gets tougher to spot. In the event of any incident I would still like to be able to physically see where it has gone.

Gracias seniors. Seen it but have no idea on it myself,sorry All I would say is how complicated do you want it to be Mine is used purely so I can see what I am filming,not into setting distance records or anything like that. Did this the other day,did 3 5 minutes flights and loads of editing to get this Might redo the flights at some point when I get a bit better.

Yeah it is,I was lucky as I had sold some expensive stuff just before I bought it so didn't notice the cost as such. The Phantom is going to be the camera platform and I am going to use the F450 for fun,I might stick a FPV set up on it but wont be filming with it.
