@@GiantAntCowboy yes diy, 3d printed, i use a 1.5mm2 domestic electrical copper cable and the base is 1mm thick copper plate. I forgot to mention that is with the old dji unit, two hglrc antenna.. it's awesom yes, first time for me that i reach as much km.. i would like to test 10 or 12km the next time, with 6000mah i fly more than 20km flat
I was already missing your videos and waiting for a new one. You edit them in calm, esthetic, pleasing manner. They are like ASMR, I enjoy them even if content is not relevant to me. For example I do not have and do not fly DJI.
Hey man thanks, I appreciate you on-going support! I wish I could produce more videos, but my obsession with details and lack of free time limit my production capacity to like one video a month… which system do you fly the most? I have a few videos in the works.
@GiantAntCowboy I enjoy flying fixed wing planes line of sight. I also enjoy technology, so I occasionally fly FPV to learn technology and try new systems and setups. Curently, I use Walsnail V1 goggles with different Vtx.
@@Mr.Laidukas cool, I haven’t built a fixed wing yet, though I used to fly RC Planes years ago. It’s on my “to do” list! WalkSnail is perfect for fixed wings, can’t believe some of the range tests I’ve seen!
Yea, curious what the O4 or the future of other FPV systems will bring. Even after years of doing these tests I’m still amazed by the capabilities of these systems!
@@Arcticfawksie No hate, just to put some counterweight here: I am amazed by the Goggles 3! Best and lightest fit for me, don't even feel them on my head and face! The picture, range, screensize and over all handling has reached the furthest optimum possible. Will never upgrade again (lol)! The Avata 2 is a good longrange cruiser and an amazing explorer with all its functions! But not suitable for true freestyle at all. Can't wait to slap some 04 Air unit on a built!
Yea, “take it with a grain of salt”. There were some variables that may have affected the results. All the antennas I used were Linear or LHCP, but since the X2-Airs are RHCP I had to use a different set of Helicals & Omni antennas which were connected using UFL-SMA connectors. So these variables could have created performance issues, however as mentioned i did have similar glitches in my original HDZero tests years ago. This X2-Air setup did perform the best through the gantlet though. It’s hard to do perfect tests with all these variables. Thanks for watching, appreciate the comment. Cheers!
Yea the stock VTX antenna works great, I just found it loses performance when turn due to its size. Using two tall Omnis isn’t necessary but does offer some performance gains. Appreciate you sharing your experience!
@@farisnazeri9841 thanks, appreciate the support. If WalkSnail wants to send me a setup I’ll test it. I’ll reach out to them. However feel free to send them a message too, it always helps when others recommend my channel. I’m certainly interested to see how higher power performs in these tests!
Thank you so much for the great work, the way you set up the screen is super professional now! I would have preferred some more "usual" upgrade patches only instead of the multiturn-helicals. Did you ever try the Maple Wireless Mjolnir? I have them laying around, waiting way too long to finally build a O3 setup with the Goggles V2 for them.
Thanks, appreciate the comment. I’d love to test more antennas but decent high gain antennas are expensive. This video will only make like $3.50 in ad revenue… so I can’t justify buying antennas just to test. These Helicals only cost like $5 each to make and perform great! Are they’re any antennas you’d like to see me test though? You mentioned the Maple Mjolnir setup, maybe I can reach out to some companies for samples to test. Thanks for watching, cheers!
Interesting. You should try 4 helical antennas: you'll probably get an even better bitrate and lower latency at that range. I use 2 Pergoda triple feed patches on top with the Iflight Crystal plate and get reasonable range, but not as much as you got with the helicals.
Yeah I bet quad helicals would work great. I’ve used that setup on my HDZero and WalkSnail quads in previous videos. For this setup I’d like to use the iFlight Crystal antenna simply because it fits so nicely. Quad helicals are tricky to attach & aim properly and have to be removed after each flight. Thanks for watching, appreciate the suggestion and maybe for testing purposes I’ll make two more LHCP Helicals. Cheers!
@@user-qs7hz9se2w sure do, here’s a basic process - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TS4fYcT3DEE.html Very easy, been making/using them for years! Cheers!
@@user-qs7hz9se2w yes, and no. The DJI FPV uses both 5.8ghz & 2.4ghz for video and control link. These antennas are designed for 5.8ghz so you’d be reducing the 2.4ghz performance. Additionally the DJI FPV uses linear antennas, and these are circular polarized, so there would be some loss there as well. However if you ran two helicals on top, and kept the stock antennas on the bottom you’d probably see some performance gains.
Did I miss the control setup? The one with stock DJI v2 antennas on the goggles all the way around and the stock o3 antenna on the drone... Thats how I do ALL my LR now and I don't need to worry about turning my head to aim for signal. With MIMO we can have gain through beamforming, and when we swap to antennas that don't take advantage of that we have to rely on the antenna gain by itself (no MIMO gain!). When using stock v2 antenna, the best drone antenna I found is the long FlyfishRC o3 antenna.... Also, food for thought: I was just flying tandem with a buddy with patches and true rc stubbies on the goggles and long truerc sma antennas on the o3 in the drone and when he had signal issues a few km out I had perfect video. he lost video and had to ascend, while I was just following him up wondering whats wrong 😂
You’re basically saying that using Linear antennas allows the system to use multipathing, or bouncing signals to strengthen the signal. While using CP antennas eliminates the ability to use these bouncing signals? I would think this would be more useful in a parking garage or bando situation than in long-range where higher gain directional antennas should perform better. (Though theoretically directional linear antenna would be best). In my tests my high-gain CP antenna setups seemed to perform better. Regarding your buddy’s setup, I wonder if he wasn’t aiming his patches well, or if there was just a general issue with his setup. Eitherway great info, appreciate you watching and sharing feedback! I continue testing and recording results, but let me know you thoughts.
@@GiantAntCowboy multi path interference is not a problem with DJI digital transmission, the packets are serialized and it knows time of flight for the packets over the air, so there's no concern of displaying the slightly older and out of phase reflections. Antennas as the engineers designed allows the o3 to use creative phase offsets in the transmission and reception of signal and this forms constructive interference to boost this signal. Aiming antennas really can be a thing of the past!
@@BrandonBeans but you’re saying this only works with stock linear antennas? I didn’t actually test the stock linear antennas too much because I didn’t think performance was so great in initial testing, especially through “the gantlet”.
Great Tests! Regarding the long range part, do you prefer the DJI Goggles V2 for your daily flights to the newer models or is it just that they have a better mounting interface for the different antennas to run the tests?
Thanks man. I have actually tried the Goggles 2 or Integra yet, so I can’t speak to them. The V2 goggles are great because swapping antennas is simple, I can fit glasses under if I’m not wearing contacts, and I got them used for a good price!
@@GiantAntCowboy With the Googles 2 & 3 range improves. But have the feeling; the V2s still offer a better immersive experience of them all during flight.
@@GiantAntCowboy curious if your DIY ones are as good. They definitely don't look too, too hard to make but the OTR have nice laser cut acrylic and the craftsman is very good. The problem for me is finding decent male to female plug ins for the goggles 2.
@@Paulwhittingham here’s a video I made years ago showing how simple it can be to DIY. ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TS4fYcT3DEE.html ) However if you want more detailed explanation tutorials, search @ModelRCReviews or @FalconRad, both have excellent video with detailed steps. I’ve been making and using these for years, cheap, simple & amazing! Let me know if you have any questions, cheers!
@@Robocopter_fpv OTR look very professional, and I assume they do some sort of tuning so theoretically they should be better than mine; however mine have always worked very well, I’ve made a dozen over the years, and they only cost about $5 each. FPV shops have adapters for the Goggles 2 that convert them to SMA or RP-SMA which could be a good option. Here’s a simple DIY video I made years ago - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TS4fYcT3DEE.html
the old goggles uses h.264 encoding, while the goggles 2 (new one) uses h.265. you can punish it with very low bitrate still remains very flyable, even with the stock antennas. (I use x-airs tho.)
Interesting point, thanks for sharing. These retransmission systems (DJI/WalkSnail) make me nervous because they can disconnect when pushed too far. For mountain surfing I’ve always used Analog or HDZero, which have fixed latency/resolution, static feedback, and can’t disconnect (per say). However I’m obviously impressed with the DJI O3 system and will be testing it more in the mountains.
@@awerks12 thanks for sharing, good point. I’m guessing O3 looks better/ can transmit the extra pixels because the h265 encoding. Is there any disadvantages to using h265? Link stability for example?
The hglrc hammers are my worse antennas. I found thay the transmit anytnna frkm the wuad is pretty improtant maybe even more than the receieve. As for the true rc patches without them i have the woorse oerformmance on hdz
Interesting, I got these HGLRC antennas because the were the longest antenna with a UFL connector I could find. At the moment pretty happy with the performance of this setup.
At the moment I can’t comment on the Vista performance. I might pick up a Vista at some point for testing though, at which point I’ll post some comparisons. Thanks for watching, cheers!
@@vk2icj no, because the O3 system only uses 5.8ghz for FPV video. The 2.4ghz signal is for the DJI RC Link. The DJI FPV drone (and maybe Avatas) however can transmit video on 2.4ghz and does have noticeably better performance.
