R2Teck DVL-1 Full HD FPV video system - review and initial testing

[@alexwang007]

Add a bandpass filter on the output of the analog Tx; Use the channel that is the furtherest from the channel the digital one uses.

[@ArxangelRC]

Don't really mind not using an analogue system along with this one! :) Might be a good idea to get a 2.4Ghz video system at last... :)

[@alasdair4161]

Trust.. difficult with any untested technology. I run a backup video transmitter on one of my long range planes set to a different frequency (band), after a few events getting wiped out at long range it makes for necessary insurance. rather than wasting power running both 5.8ghz and 1.2ghz and needing a video DA, I just use a micro double pole relay with a pwm switch on a spare channel, it switches video and power between the transmitters and adds very little weight. You could do same to stop cross interfering, even just switching on or off the analogue system will work. Thanks again for an excellent review.

[@ArxangelRC]

Nice idea mate! Will give it some thought... although I would prefer to have the analogue system working full time because of my antenna tracker! A 3.3Ghz video system would be fine, just need to find the time to mount it on, and for the weather to improve, so I can have a nice flight!

[@alasdair4161]

In case you decide to try, this is the switch I use.www.banggood.com/RC-Lander-LNSRC-1A-Single-pass-Electronic-Switch-For-RC-Models-p-997192.html?rmmds=search&cur_warehouse=CN.

[@ArxangelRC]

I actually have a few similar On/Off switches... although mine are up to 10A... and I think the voltage is higher! :) Might give it a try, although today I flew with a 3.3Ghz 1W video system, and the HD and this one did not interfere with one another! :)

[@Ekirea]

I'm new to your channel and I like it a lot- great troubleshooting too!

[@ArxangelRC]

Thanks! :)

[@marioskalogeropoulos7054]

HOW CARES ABOUT THE PRICE?HD FPV IS NOT READY FOR THIS DECADE.GREAT PRESENTATION AS ALWAYS A.RC

[@ArxangelRC]

:) And yet DJI has done it! :)

[@marioskalogeropoulos7054]

@@ArxangelRC I'LL BUY A MAVIC PRO FOR 1K REMOVE VTX AND PUT IT ON BUFALLO FX79 FOR 7KM FLIGHTS!OHH S..T I NEED THE VRX TOO! DAMN IT'S 5.8G I'LL STAY ON 1.3G FOR NOW!WE DON'T HAVE TO CONVINCE EACH OTHER UNTIL FREQUENCY AND DICTANCE CHANGE~20KM(I'VE NEVER FLY MORE)LET THE PRICE ON ME,IF IT'S WORTH IT YOU GET WHAT YOU PAY/OR YOU SHOULD.BUT NOT YET!

[@ArxangelRC]

Buying a mavic and scrapping it for the video system and gimbal is always an option... although you will still need a second radio for control... might make things a bit clunky! :) A directional antenna on the ground will surely get you out to 20kms in HD... but it is a heavy DIY project... and my idea is to find an off the shelf solution that everybody would be able to use! I don't see a problem with testing out these systems... at some point one of them might become a big surprise! :)

[@robertnicoll9712]

Good vid mate, you might benefit from having a crude spectrum analyser on hand, something like the RF explorer 6G combo.

[@ArxangelRC]

My friend has that one... and we do use it quite often to be honest! :)

[@senhaiser]

whether the information written on the monitor can be lost all the OSD so that this unit can be used as a wireless camera shooting

[@ArxangelRC]

Meaning can you switch off the OSD overlay?

[@ArxangelRC]

Sounds good mate! As long as you are getting the results you are looking for, its all good! :) The MFD AAT works for me, but I do enjoy the cheap price of the Omnibus F4 Pro boards running ArduPlane, compared to the 200 USD price tag on the MFD AP or the Vector... so don't mind doing a bit of soldering to get the planes outfitted! Besides... truth be told, if I had 2 planes, perhaps would be OK with a more expensive AP because of simplicity to setup... but I have 6-7 planes fully equipped with APs and full FPV gear, cameras, etc., and if I had to shell out 200 USD for AP alone for them... it would get quite expensive!

[@samuelsalomao4263]

Hello @ArxangelRC, Would you have any update on this system performance with no analog interference?

[@ArxangelRC]

As a matter of fact... I just published it! kzbin.info/www/bejne/l5DMi6WDh8RkoJI

[@aldoyosbel1728397263]

Had someone else try this system, what do you think? Thanks

[@ArxangelRC]

I think people that are using it on copters for short range work are quite happy with it.

[@aldoyosbel1728397263]

What is the one that you use on you own plane

[@ArxangelRC]

I mostly use 5.8Ghz analogue systems, right now I am testing the CUAV Hack Link on the Believer... :)

[@aldoyosbel1728397263]

When u test it let us know, do u still using li ion battery or lipo on u own plane

[@ArxangelRC]

Will do of course! Yes, I use a LiIon for my Clouds, but the battery is too small for the Believer, so I am still using a Lipo there, but am planning to make a LiIon for it as well soon! :)

[@alejandromartinolikatuchin7714]

Hi, how do you respond in a football stadium, with so many people, does it interfere? Greetings.

[@ArxangelRC]

Haven't tested it in such a situation, so can't really say!

[@LA6UOA]

Nice review!

[@ArxangelRC]

Thanks! :)

[@TechTronic9000]

Interesting results, too bad that the analog FPV jams the HD stream. Reminds me of an event a few years ago on a car road trip, my GPS unit had a wireless revering camera and along the road there were some gas stations using apparently the exact same wireless video units and my GPS would switch to reverse mode and show me footage from the security systems of the gas stations ! I can only imagine how secure is such kind of a "security" system :D

[@ArxangelRC]

Well... it is not unexpected actually! Both are in the 5Ghz band and the antennas are very close to one another! Will do more tests next week or the one after that will get to the bottom of this, but when the analogue is off... it looked very promising!

[@cherrywang4382]

I totally agree with you,analog FPV is totally too bad.

[@mimlomiani6949]

very nice :) But the price really out of many peoples range :(

[@ArxangelRC]

True, but it is still new technology! Will get cheaper as it develops and gets more popular!

[@mueller9539]

yes ouch on the price, but i do have a dream of having an HD link someday... ...someday.

[@ArxangelRC]

Hahaha, back in the day I thought $400 was too much for an antenna tracker... until I spent yet another flight trying to aim the receiver antenna at my plane at distance... without much success! Right after that flight it was clear that I will have to pony up that $400... and to be honest I have not regretted a single cent spent on that antenna tracker. Now... I don't want to have to wait so long to find a working HD system... so I am at the point where I am willing to invest a bit to find a working one even before the technology is fully developed! In all honesty it should have been developed a long time ago, as the analogue systems we are now using are ages old technology... they should have been made obsolete a while back!

[@mimlomiani6949]

Yep..:) I agree Totally with you that it should have been developed a long time ago. I think some people who have many Good idea's but not that much capital are not so willing to risk in a world where the big and powerful dont play it fear, well most of the time. What I mean by that is lets say that you have a really good idea for a google. You know that if you dont do anything about it not so long from now someone else will because it is just so easy and helpful, but you know too that you can not produce it localy and if you do the prices doesn't match with the world today. So one has one option, have a trip to china and that is start of all your problems. Because as soon as you come there with your idea if you dont have enough capital to produce many before the copy makers start on you too :). So I can understand sometimes the price must be high if you want to be one of the first to have the system and a reliable system too. So maybe 400 is not that much when you look at it...:) Anyways thank you for sharing.Looking forward to see some good video's from you, and I really hope that you will have many subscribers because you deserve it...

[@mimlomiani6949]

I really Hope that your dream come true :), I too wouldn't be sad or anything if one day I find one at a good Price.

[@universerc7045]

Great video ! waiting for range test with a FullHd screen +)

[@ArxangelRC]

Haha, thanks, but problem is I don't have access to a full HD screen that I can take with me to the field... :(

[@aerofpv2109]

I'll be looking for your next video which you will have better success. Always great to have another option for HD vTx. I am liking the FPV Blue we have here in the states tho.

[@ArxangelRC]

FPV.Blue is nice, but it is on the 1.2Ghz band, and I really would like to stay away from it, as I want to keep using 2.4Ghz control for the time being. The benefit of a 5.8Ghz system is that it doesn't interfere with anything, and is a lot more user friendly than 1.2Ghz with all the filtering, etc., that it needs done!

[@lesjack137]

I take your point regarding 2.4, but here's a comment from fpv.blue when asked if their system will work with 2.4 control: 'The harmonic, even if 100+ MHz away, is still enough to overload many 2.4 GHz RC receiver frontends. A low pass filter on the transmitter will solve the problem entirely (and again there is one already on the PCB that is gonna see it's number of stages going up for the next batch).' So it's designed to work with 2.4, we'll soon find out if it does. It has the range that 5.8 just can't match.

[@ArxangelRC]

Right... at this point I really don't want to spend over 400 Euros just to troubleshoot that system IF that in-built filter doesn't work! It is not a problem for me to either wait to get confirmation they have fixed that and there will be no issue with 2.4Ghz, or wait until they release the 2.4Ghz version, at which point I will just use it with the FrSky R9M system. Right now, I know for certain that the 5.8Ghz band of the DVL1 works well with 2.4Ghz, so will keep to that, and will hopefully get some nice range out of this system in the coming days! :)

[@alerx94]

sorry if i bother, you seem prepared on this topic so i ask. is there any problem using 433mhz rc link and 5.8ghz fpv ?

[@aerofpv2109]

No not at all. Those freq are far apart. I've had success with that setup. Separation is also key.

[@alfonsoirwin8372]

Good video as usual... I'm interesting to get one of these high-definition fpv systems but they are just to expensive know.. Especially this one that you just reviewed.. The FPV blue is the best on the market now IMO. It will be nice if you can review it...

[@ArxangelRC]

Thanks! FPV.Blue is working on the 1.2Ghz band, and for the time being I want to stay away from that one. That frequency causes issues and I will have to move to 433 controls, will have to use filters, etc., just don't want to have to get into that ordeal right now! Might give it a go when they release the 2.4Ghz version!

[@alfonsoirwin8372]

ArxangelRC Oh. I didn't know that was that complicated.. I look at bonafidepirate vid. And I don't see him have any problems.. Maybe because he is using different systems.. Anyways, I think is better to wait some time so those HD system get better

[@ArxangelRC]

If one usually flies with 1.2Ghz video... he will have all the necessary gear and filters to negate its effects. I do not, and really don't have the desire to get into that at this time!

[@cherrywang4382]

FPV blue is only 720P resolution and the lantency is not that pretty much good.I can not see how terrible is the FPV Blue bad Video quality

[@EnglishTurbines]

Why dont you try moving your 5.8G Analog VTX to the very front of the plane, right now they are right on top of each other? It may be enough to stop it, although having two 5.8G VTXs on the same plane is never going to work is it..? I still say 5.8G will never be any good for Video downlink, even DJI use 2.4G for control and Video, difference is, its encrypted. 1280mhz is actually an amateur TV HAM Band here in the UK, but you are not allowed to have an airborne transmitter.

[@ArxangelRC]

Actually, for the separation test I will move the HD system up front, so I can use it for flying as well, and see how it feels. Easiest way to do this would be to them just replace the 5.8Ghz analogue Vtx with a 3.3Ghz one and test again to see how they will do together. 5.8Ghz is very user friendly as it doesn't interfere with 2.4Ghz control, and I would like to keep using that. As for DJI, older systems were on 2.4Ghz, but their new systems operate on both 2.4Ghz and/or 5.8Ghz, and getting spectacular ranges even without directional antennas! We have done some pretty amazing stuff with the 1st DJI Lightbridge here, but since it is 100mW we needed some pretty big antennas!

[@EnglishTurbines]

The answer is to use a 1280mhz analogue Video Downlink.....I predict that the killer here for this 5.8G HD system will be its distinct lack of range, I'd like to be wrong, but Im guessing I won't be. Its why FPV Blue is using 1.2G, it has enough bandwidth to carry the HD signal, but it has range too, due to the lower frequency. Those 5.8G receiver antennas just won't be good enough.

[@ArxangelRC]

Actually this system is not new, I think it has been sold since Jan this year, I only found out about it recently! Everybody that has it and I have talked to is actually quite happy with it, and there are a few videos around with it, showing it could do a few hundred meters at least, so I am optimistic! Next week I will be testing it with a 3.3Ghz Vtx system, the two shouldn't interfere with each other, and we will see! End of the day, I could leave on it on the plane... but will have to be brave about it and trust the iNav to bring the plane back! :)

[@docromano]

@englishturbines Problem being that those frequencies are used for mobile GSM services in most parts of Europe, especially between 900 and 1800Mhz..

[@ArxangelRC]

Actually around 1280Mhz is not for the GSM band... but around my parts we have a pretty strong radar on top of the mountain that operates close to that frequency, so trying to fly at those frequencies is not a good idea around here!

[@docromano]

GSM! Not gps ;)

[@ArxangelRC]

Yeah, that;s what I meant! Sorry for the typo! :)

[@jamestran347]

Theres nothing wrong with it you set the the 5.8G to 5.2G that is out of range, anthing under 5.5 is very bad, it must be above that? the higher the megahertz, the greater the lower the latency, it was a bad setup))

[@ArxangelRC]

Could be... will have to test that on the new one! :)

[@imemyself2820]

$570 I can get 4 x TBS systems for that price.

[@ArxangelRC]

That is true... but is the TBS an HD system?

[@imemyself2820]

To be honest, I dont like TBS, it is too easy if you have the money. But at least it works like they said it would. It would have been nice if this worked, now all your work was for nothing.

[@imemyself2820]

I have my vTX (that may be SD-ish?) for in-flight transmission then I have a 4K camera recording. What more do I need? :o

[@ArxangelRC]

Trust me... it is a COMPLETELY different experience to see the image on the ground in HD while flying! Quality can't even begin to compare, contrast, etc.! Not even on the same planet!!! As for my work... hasn't been for nothing! The system has shown that it is capable, just need to mount the antennas better and go out to see just how capable! :)

[@imemyself2820]

Well, it is still seem a bit redundant and expensive to me but I think we will see more consumer-priced products in a year or two. Happy flying :)

[@jamestran347]

yOUR 5.8g IMAGE TRANSMISSION IS ON 5.2g 5220g, THAT IS BAD!!,

[@ArxangelRC]

Will test it on the new system! :)

[@georgitushev]

Great work! To test the range you can use your arduplane, send it on autonomous mission around. Just an idea:) NAZDRAVE

[@ArxangelRC]

That is another option, which I will consider, but my EVE needs to have its motors replaced, and the Clouds needs some rewiring, so if I don't get the time to do any of them, I will keep the system on the Believer and just use a 3.3Ghz Vtx for the analogue bit... or fix my iNav, so it doesn't try to crash the plane on RTH! :D

[@Ryuuken24]

Conclusion, it's shit and waste of time, hdmi connector only when 720p cams have under 30ms delay. I'd rather fly analog than be looking at a 100ms screen.

[@ArxangelRC]

I am not done testing this... later tests have actually proven the 2km range, and now I have improved the positioning of the antennas... so should do better!

[@franklee90]

Its expensive !!

[@ArxangelRC]

It is... at first... but if it is really capable of reaching at least the 4kms promised... it will be one of the cheapest per km of range HD systems on the market, and most certainly the cheapest one operating on the 5Ghz band.

[@franklee90]

Thanks, Does it need to change antennas to circular polarized or not??

[@ArxangelRC]

At the time I need to do more testing to see what the stock antennas are capable of, but I've contacted R2Teck about this, and they claim that they have done tests with circular polarized antennas, and supposedly the system does not work well with them. Linear polarization is preferred!

[@franklee90]

Thanks again. Im so passionate about FPV. Have a nice day !!

[@ArxangelRC]

Thank you! Have a nice day yourself! :)

[@andyantomr9696]

don't buy R2Teck product. this is worst rubbish product. i have bought it and use it. the resolution has been down. i connect my full hd laptop to my full hd tv using this product. but the image not so clear. like have some distorsion. very very disappointed. not same like what the sales marketer said. mine are R2Teck DVLM100.

[@ArxangelRC]

Sorry you are having issues with that system! Depends on what you will be using it for though!
