900mhz VS 2.4ghz FPV

[@BanxyNZ]

One of your best so far. Thanks for all the hard work you put in to these projects. ...

[@patlevis2430]

This is the second great rescue I have seen from yours videos! Great job man! Next time I crash my plane, I call you for rescue.

[@dietcoke1996]

Man, I sat through all the 29 mins of this vid (1st time ever!) and I enjoyed every minute of it, especially the long walk to retrieve your FPV plane, lol. I'm also thinking of going FPV but with what you have shown that this isn't going to be easy for me either. I'm using Spektrum 2.4G and thinking of getting the Dragon link and a 900mhz FPV system but with the video you have shown, there are incompatibility issues. Dude, keep up the great job here.

[@rctestflight]

@bingobongo17 k thanks, I will have to do a sequel

[@rctestflight]

@danny9599 I know that, that antenna was built to fit the wavelength

[@catamaranman333]

Man1 That's alot to digest! Probably my favorite of your FPV videos so far!

[@rctestflight]

They are not magnets, just ferrite rings. You can get them from any FPV store.

[@User5cod]

You are one of the rc guys who makes the best reviews on youtube, thanks, keep the video comming

[@rctestflight]

@FivelingoPilotVieuw So the 900 patch shouldn't be 6" up? IBcrazy from rcgroups said that and hes a genus

[@MarkShannonroad_videos]

900MHz has a longer wavelength then 2.4GHz, so the antennas for 900MHz are longer then 2.4GHz. Not sure about the why the video gets noisy on the return trip other then maybe the antenna is tilted on the aircraft causing a different polarization? One thing you could try is mounting the antenna horizontally (Sideways) and see if that helps.

[@rctestflight]

@bingobongo17 All the way to the bottom of the ground element?

[@TuckerGott]

Very interesting stuff! Useful for my projects too. Keep it up! :)

[@gentleboy5497]

oh wow hello! didnt expect to see you here 😆

[@rctestflight]

@simio1337 when I turned around there was really nothing in between the antenna and the antenna on the ground, would a camera near the antenna line of sight do anything?

[@Rehost2]

Hilarious video dude. Rare we get to watch others do all the retrieval work. Great job!

[@heli400]

(only 7:42 into the video so far...) but where is the (stock) antenna for the 900Mhz? i see in the beginning of the video you build a "same" antenna for the 900 Mhz but did you test it? use it on the 2.4Mhz and see if it craps out like it does on the 900 Mhz. Maybe that is where your problem is starting. I know with stereos speakers you need to match impedance for maximum power transfer. perhaps the same applies for antennas. but I'm new to this so Imma going to watch the rest of the vid....

[@Johnellenberger1]

Hey I will be moving sometime in August to Salt Lake City for a job at IM Flash technologies. I understand that you live close to there? Any info on the area would be great? Any good local fields to fly at ect.? Maybe I'll see you out this summer doing one of your videos? -John

[@rcflyboynj]

Awesome!!!!! looks like you have a good setup there. Have you seen any of the HK 2.4 Ghz FPV systems?

[@mikep95133]

I've done some rf work. The biggest problem with any band that you pick is that it's very important to characterize each radio, each length of coax, and antenna. A VNA (vector network analyzer) is the best, but most expensive tool for testing coax and antenna. I've tested enough antennas to find that performance claims are a joke. Adding any coax to move the antenna away from the radio, diminishes reception and gain for a few reasons. A field strength meter walked around the plane can be useful.

[@drummerdonniedotcom]

Have you considered helical ground antennas? I've had amazing luck with my 5.8Ghz Fat Shark Predator V2 system using 3 wind and 5 wind R/H polarized antennas. I attach the antennas directly to the goggles so simply aiming my head towards the vehicle helps with reception. I've been using the stock rubber duck antenna on the receiver, which will change this week when my cloverleaf R/H polarized shows up.

[@Johnellenberger1]

Also, using diversity with both a 900mhz patch as well as a Yagi antenna gave us a 9 mile range. At least that's how far we pushed it before the batteries got low on my friends 9 pound quad.

[@opticell]

Glad to see FPV is in Utah. I would like to join up with you guys one of these days. Just getting started, and have ordered a Ritewing Zii, FPV from BEVRC (432, & 900), and sprung for a Ruby. Thanks for the video, sorry to see you have many problems, I will be going through a similar phase with my new system.

[@Manofcichlids]

Iron Mountain never looked so good! I too am near PC but have yet to build my first fpv system (reason I stumbled across your video)...hopefully I can get everything figured out and up in the air with my 6 foot telemaster build with twin engines so I can mount all my gear up front like yours. Well done!

[@JaycubL]

Do you know if you are legally suppose to have a ham lisence or not to use this stuff?

[@pagani8]

Who normally films for you? Great video, a lot of info and flight video, thanks!

[@Killerplanes]

great vids! Love the custom planes, too! I'm signed up - I've only seen a few of your vids, but I'm coming back for more! Did you finally get the 900MHz system working?

[@rctestflight]

@RoboTekno thats what this video is about, maybe if you would watch the whole thing you will find your answer

[@rctestflight]

Im like 20 miles from Salt Lake. I know there are a couple flying fields down there but I've never been to any of them. D

[@lsi624]

There is enough empty space in your plane to fit a fluffy kitten?

[@Rcschim]

Great and entertaining vid! I always wanted to see a comparison of these 2frequs. Yur sure right - one of the things that 900 can do better is go through walls and stuff. Good you got your plane after this crash. My 2.4ghz vid only went out once really bad and that was cause i let come a hill between me and the plane :-) maybe you should make your range tests on the ground with the car... Video shouldnt get bad if you face towards you... Only in hard turns... Did you leave the radio cone of th

[@daskipper]

Wow, this might be the best video on FPV. Thanks for the work!

[@420choky]

ive gotten 5 miles on 500 mw 2.4 .. 14 dbi and a 24 dbi hyper dish with a duo receiver .. good vid man ,, do you use the go pro for fpv?

[@55spirithockey]

I really like your fpv videos. What type of radio do you use for long range flying? What type of range would you expect for a standard Spektrum radio with an Orange RX?

[@jordanhuusy]

hey this might be a stupid question daniel but is it ok to be using a 2.4g tranmitter and a 2.4g video tx/rx? will they interfere with eachother? -and also just fyi i enjoy your vids of rc AND skiing cuz i ski myself. keep up the videos! thanks jordan

[@para9111]

What an adventure-.lot of fun to follow.I kinda saw that one coming.Regardless keep up the great adventures.Working through your problems makes it interesting.

[@RPProductions]

Nice Video, as always. FPV seems so confusing so I doubt I will ever do it. And you do realize how many people are going to call you after they see this, right? LOL

[@Chio_OB]

Great video, didn't think I would last the near 30 mins but it flew by, very interesting, looking forward to more like this and hope to pick up some more fpv tips before I try it!

[@rctestflight]

@rowdyrodcumming 2.4ghz antennas wont work with 900mhz or vice versa

[@aposdfzxc23]

was that a turnigy 9 channel radio that your were using for dragon link?

[@rctestflight]

@simio1337 Ok I will try that, I have taken a 2.4 rubber ducky antenna apart and all thats inside it is a dipole

[@JaredReabow]

i rec that the reason the video got worce was because the plane flies at a slight pitch which means flying away your antenna is angled down towards you, flying back its angled up away from you, maybe try angling the antenna or putting it on a balance weight to keep the aerial steady

[@jbrown21m]

Uhmm, entertaining video. Enjoyed it.

[@tqexplosion]

Hey man, whats the setup on your long duration plane? (the one with the orange wings) like motor and prop specs, what wings were you using.. anything that help :)

[@gtoonstra]

I noticed that your screen goes entire lime green when you lose a significant amount of signal? Is that how your receiver works, or are you capturing this through a laptop of some kind (USB capture card?). In the latter case, some capture cards have hidden 'switches' that allow you to keep showing whatever signal is there, even if it's noise.

[@JimBridgerHarney]

So many casual homestar runner references

[@brandon429]

what in the heck did you use to zoom in on the lost plane on the mountain>>! was that a camcorder zooming in that far and tight?

[@wettfeat]

So is the picture quality better on a 5.8GHz system vs 900mhz? I've only flown 900mhz and I know it's not the best but I also fly on a small screen.

[@lewandlo]

Gr8 stuff dude. Very informative and fun to watch. Thanks for showing..

[@jatu3683]

Have you tried any circular polarized antennas on your Rx like from IBCrazy?

[@dtiydr]

What motor and propeller did you use for the plane where you could go for an whole hour?!

[@ICEGTN]

Here are some tips: The higher you get the antenna from the ground, the better, like 5 meters high (16 feet) would be a good start. And the higher you fly, the better. Polarization: it's the most important thing, make sure both antennas are exactly polarized or efficiency will drop drastically. If wrongly polarized, the antennas may never see eachother even at very close distance.

[@sk8rboy1255555]

Any plans on testing out 1.2ghz?

[@JeroenBrosens]

Hey Daniel have you ever tried using a SPW antenna for your TX and helical for RX? It gives massive range with way less interference. Are your houses built from stone or wood? Here in Europe our stone plus reinforced steel don't like any signal.

[@rctestflight]

Yes I frequently use them now but at the time this video was made they were unheard of in FPV.

[@JeroenBrosens]

rctestflight ahh right now I see it, your video got recommended to me by KZbin, thought it was a new one! So never mind :-)

[@mrdlg2u]

Hey, I have followed your videos for quiet some time, you have come a long way!! I run a Dragon link with a 500mw, 2.4ghz video Tx. I also had an issue with being "to close" to the video receiver... here is what I did: I added a 5.8ghz to the system... the video signal coming out of the 2.4ghz receiver now goes in to a 10mw 5.8ghz Tx. Then I have the 5.8ghz receiver hooked to my video monitor/goggles.

[@rctestflight]

@mrdlg2u i just bought a 20' RCA extender

[@rctestflight]

@humanmissile any other frequency besides 2.4

[@sco215]

can you tell me how you record to your laptop? i have been wanting to do that but dont know how. thanks

[@ICEGTN]

Elevation and azimuth: dipole antennas radiate perpendicularly. So tilt the antenna to make it perpendicular to the airplane. Tilting the antenna may affect polarization, so try to reach a compromise. Banking the aircraft may affect polarization, keep it in mind.

[@slidewaze]

That was 29 minutes? Nicely done Daniel...

[@rctestflight]

@melrobRTF I get the same results with all the antennas I try

[@kuba651]

@rctestflight Can u please narrate the FPV Flights ? its awesome when you do commentary :)

[@BlackdogRRT]

One of the guys I fly with does exactly what you are talking about. He has had problems with his DL interfering with his vRX. So he attached his DL on a pole and ran some CAT 5 cable. Distance between him with vRX and his distant DL is like 20 feet or so. Works well now.

[@CBobbya]

Hi, I'm looking to record with my laptop as well along with my gopro. Question, what kind of connection device did you use to connect and record with your laptop.

[@0WHISKEYTHROTTLE0]

you make your own planes?

[@KJ4CTZ]

Nice video for comparison. I am running 900Mhz in Florida and the signal has not impressed me especially in turns.

[@rctestflight]

@LIPOPILOT funny you say that because im making a longer cord right now lol

[@Matthewandmatthewpwn]

This is going to sound really stupid but will the 2.4ghz video interfere with the

[@Matthewandmatthewpwn]

Was this using a 2.4ghz plane transmitter

[@Austinpowers46]

Hi wot program u using to record video on you laptop? Cheers.

[@almostprestove]

Awesome video man, very informative. Wanting to get into FPV when I can afford it, this was excellent for noobs and vets alike I think.

[@tomtom4867]

what frequency does dragonlink use?

[@peru20032004]

Hello friend today what the best frequency for FPV and what the best RX and TX?

[@ufochannel01]

have you tried 5.8? and use a helical antenna and airblade both lhcp. i have had really good signal using this combo. also i use immersion 600mw vtx. i also use just spektrum dx8 and satellites i have never lost signal i've flown 3 miles out no problems. new laws say we cant fly fpv further than your spotter can see your plane by line of sight. please don't give fpv a bad wrap by breaking rules to much. good job giving info thanks.

[@zyxelina]

Haha, I love how you wrote "If found call this number" on the wing of the orange plane :D

[@FivelingoPilotVieuw]

@simio1337 I agree, but here in the Netherlands it's the only legal option next to 2,4Ghz to use (FCC is stringent in my country), I am flying my bird on 2.4Ghz. Also it's not allowed to fly with long range systems like the Dragon link here, I have the intention to use a tracking device for the 5.8Ghz in the future, a circulair antenna placed on it will give much better results. At least for the moment I have a nice video quality in my goggles.

[@slimjimandpepsi]

what country do you live in?

[@bingobongo17]

Have a look at dipole antenna construction, the coax cable should be perpendicular to the elements - ALWAYS.

[@CollinRandallOutdoors]

Hey Daniel I am wanting to start getting into fpv what would you recommend for a good starter kit? Obiviously nothing long range just something fun to learn on? Any advice is much appreciated! Thanks

[@rctestflight]

@aposdfzxc23 ya but them I switched back to my dx7

[@Matthewandmatthewpwn]

2.4 control or the opposite way around?

[@RoboTekno]

What do you recommended, 2.4ghx or 900mhz

[@rowdyrodcumming]

Epic video, nice one!! Great unbiased view, keep up the good work.

[@lsi624]

Any thoughts on 5.8 ghz?

[@JeroenBrosens]

LOL at 25:35 your cat walked over the keyboard or something?

[@yxhankun]

which software is being used on the small notebook that is doing the recording, would u show us the link? Please!

[@trybicki100]

I'm looking for a good ground screen could you recommend me one?

[@jovanjanevski3747]

Was the receiver antenna 900MHz?

[@Killerplanes]

great vids! Love the custom planes, too! I'm signed up - I've only seen a few of your vids, but I'm coming back for more! Did you finally get the 900MHz system working?- OH- I just saw the demise of the plane on the mountain- no crashproofing equals no plane!! Check out the crashproof planes on the killerplanes channel- it would be worth it to protect your rx and video stuff!

[@Ultrarc]

the reason your 900 mhz is not working with dragon link is because dragonlink is 433 mhz the second radio harmonic of 433 is very close to 900 mhz

[@mikehawk4517]

But he was on 2.4 GHz?

[@Ultrarc]

is control was 433 mHz, and his video was 900mHz

[@mikacotty7607]

thank you. What a great way of explaining this for me.

[@martinba77]

Awesome video and very helpfull information! Thanks for sharing all your work! And great pictures too! Bye!

[@derbaronfpv2354]

do you use your 2.4 ghz video transmittier with yaour 2.4 ghz radio ? :O so it work fine? crazyyyy

[@RcLento]

20:10 the resom may be the hot balloons radios because everyflying object has to have radio ! Probably balloons have efected

[@alexhydea]

is 900mhz iligal?

[@Namejjvkkr]

If you have a Android phone or tablet you can download an app called WiFi Analyzer, which makes it very easy for you to see what channels on 2.4GHz that's lease used where you are. If you have an iPhone or other i-device you have to jailbreak it to download that app. If you have a jailbroken iPhone/iPad/iPod, just go to Cydia and search WiFi Analyzer and you will find it. Just a tip, because you seem to like FPV on 2.4GHz :)

[@masso172]

Im barely one minute into the video but isnt it incorrect to have same type of antennas for two different frequencies?

[@rctestflight]

@gtoonstra its my laptop

[@FivelingoPilotVieuw]

Looking forward when you are going to test some 5.8Ghz systems, pleace your receiving antennas as high as possible to cut out ground absorpsition en to enhange radiation-pattern (patterns change at differents heights), in generally for all antennas should be placed at least 2 wavelenghts high above the ground. Maybe you get a better radiaton-pattern from your plane if you can place it on the middle of the airplane. Nice experiments, very usefull !!!

[@tqexplosion]

nvm about the wings lol didn't see multiplex written on it!

[@jbx907]

your conclusion is perfect,,, nice video
