Walksnail is really stepping up as the "jack of all trades" of FPV. They've got a vTX for micros, a vTX for bigger quads, a firmware for racing. What can't they do???
Is the camera mounted a bit wrong? You can see the left motor more than the right, which sometimes happens when the camera is tightened offset
@joshuaBardwell What foam are you running on you goggles
@@EagleFPV43this exists on almost all caddx cameras
@@ramchandyalamanchili8258 interesting
They can't do opensource or sub 10ms fixed latency. I'd rather buy walksnail than DJI though for sure.
I used to say “I don’t notice latency” until I switched from DJI to hdzero
Same here man, even with the old school fatshark hd scout hdzero box goggles there's such a noticeable difference between the two and you really only feel it when flying hdzero for a bit. It just feels way more fluid
I stil remember some of LeDrib's words: "Oh, so that's low latency??.... it feels like flying a better battery".
This makes me appreciate HDZero even more. There's no compression loss in the grass and trees that turns them into a featureless green mass. I need that detail, especially in racing, because it's crucial information about my altitude. It's harder to gauge how high I am if I'm flying over a muddy sea of fuzzy green blocks.
Yup. Looking at this, Walksnail's "race mode" (and by extension, this video) is actually one giant ad for HDZero.
The resolution doesn't have to be great when your on a race track. All you have to see is gates and other quads. Also i feel 540p90 HDZero looks better then this new 540p race mode from WalkSnail. Im excited for the future of racing baby! Cheers and thanks JB!
The 540p mode also gives you better range on the old VTX with upgraded antennas. Better than the original DJI AU! Cheers 🍻
Sorry JB, already ordered one for testing before you posted the links. Thanks for the review, I like where this is going!
Ask your local race director if you can fly walksnail at the race! Lots of places won't let you fly it because it negatively impacts other racers and most popular timing system can't accurately track the weird power outputs. Transmitting from the goggles makes it really difficult to integrate in a race environment.
It sucks to have new guys show up with these systems to a race and having to tell them they have to sit super far away from everyone else and their lap times won't be accurate. It's very discouraging for them after having spent however long just getting the drone to fly and finally getting confident enough to come out to a race. We always try to accommodate them, but these things never get mentioned in videos like this so they have no idea
Hey Joshua, you must try analog, it's amazing!
I think running a track would have been a better test environment. Especially with other racers on the track. "Coming out of the fog," pretty much sounds like analog level to me.
When I saw the first images in 540p and the branches popping up my immediate reaction was "I'd just continue to fly analog at this point" ahah
the most versatile system became even more versatile. And I love that there is product development going on at walksnail
l liked the video info on the Walksnail system, I am probably going to get one.
Completely off topic, please tell me where you got the long screwdriver bits and adapter for your DeWalt screwdriver? I have been searching for this exact set-up.
Thanks for the review. I was torn between the older 1S vtx and this new v3 one. I am a little reluctant to buy the older one because both you and madstech bricked those vtxes during review. Can you test out the durability improvements of this new VTX? Especially if we can limit the output power, remove the casing and have a more durable 1S vtx for 1-2S toothpicks?
Also is the camera that comes with this vtx a newer variant? The document says it's supposed to have better night mode noise reduction.
And you're right.
With HDZero, I used to be frustrated trying to watchout for thinner things like electric wires, thin branches etc..
With Walksnail, I seem to be worrying about latency spikes.. I am noticeably more slower/cautious with my walksnail build. I have been trying to avoid tinier gaps etc.. but that may also be because i only have one walksnail build and i don't want to wreck it just yet. Or maybe because i fly walksnail in 16:9 mode mostly..
Really cool they made this system work in fixed latency... But it looks notably worse than HDZ... and in some scenarios even worse than analog... somehow for fixed latency analog is still a really strong link - especially if you account for the compactness, price and robustness of this system in comparison to the digital divas ;)
If someone has shown me the WS 540p footage and I didn't know any better, I would've said that might be the best analog video I've ever seen.
Meanwhile, I've watched tons of 540p HDZ videos and recently got the nano 90 camera for myself and although 540 is a noticeable drop from 720, at no point have I ever confused HDZ footage for analog and that speaks volumes.
In general, I think it would be good if every system (DJI, WN, HD0) had these 2 modes. Variable latency for slowly exploring the location in the best image quality, and the fixed latency for sbang tricks, bando and racing with the best latency... I think most people like to do both...
The overall latency of the Avatar system is relatively low, but you really do feel it when it jumps around. After flying a lot of analog this summer and going back to WS, it’s the variable latency that kills the fun a bit for me.
I just updated the firmware and can’t wait to gives this a try! I’ve been waiting for this for a while now.
I just watched some of the HDzero dvr, and honestly they both look similar quality. The HDzero breakup is probably the hardest thing for me to get past. Maybe it’s worse when watching the dvr on a monitor? Kinda like analog.
Bitrate looks good too. I’ve got 2 quads with v1 and a Cinelog35 v2 and both of my v1’s drip to 14mbs and stick there as soon as I get 50’ away. I’ve replace antennas and resoldered everything. All on newer firmware. 🤷🏻♂️
Being honest, this doesn't get me any more excited for Walksnail, but it does get me excited wondering if HDZero could introduce a mode that retransmits missing data packets to improve range at the expense of latency.
They've already shown the awesome versatility and performance of HDZero and I would love to see a "quality" mode.
HDZero couldn't do that without a total hardware redesign.
They are forced to do that now imo to keep their market share...
You didn't say anything about the camera - it has 4:3 native sensor it that nano size so it's more preferable for racers to see more on the top and the bottom of screen. AND, it's race mode, not cpt.Vanover freestyle mode, not fancy beautiful joy mode to perfect see every branches it the dark behind your barn - it's for race, when gates are clearly visible from the space and it's pretty enough for it. So it's not a cons.
Sounds like what you might want cold be really environmentally dependent because of how the compression works. For example, If you dont have branches to worry about. HDZ is trying to give both too with the 1080p mode.
Does this work with all walksnail vtx?
Fantastic flying and review, Joshua! Thanks!!! 😃
If it still records in 1080p while you fly in this mode... It seems like a non brainer!
Anyway, stay safe there with your family! 🖖😊
The onboard always records in 1080p, only the goggles will have a 540p recording
@cotillion1687 Yeah, that's exactly what I meant! In this case, fantastic! 😃
I hope some day they make a way to record at higher quality, even 2.5k... But until then, it's more than good enough. 😊
It would be cool to switch from 1080p to 720p to Race mode with a switch on your radio. So you can explore and take in the view and then rip balls in close proximity all on the same pack.
The problem with that is between 720p/1080p, the SoC needs to update the display resolution on the goggles, and they straight up restart when going into race mode. Could be wrong about the race mode reboot tho, that's what I saw from another video last night about the new firmware
@@mythrillium2 just a thought. 🙂
@@MudflapNichols definitely a cool thought, I'd love to be able to change video settings right from my radio too
Just loaded this up on my 1s walksnail in a 3in Ceaser Frame and and Walksnail goggles then ripped the back yard. ABSOLUTLY LOVE IT!!! No blur, studder, or signal loss. I also have some switchbacks Running HDZ and i cannot see any difference in latency or "Feeling locked in" between them. The only difference i see is HDZ colors are better and 540pwalksnail video clarity is far better than HDZ 720p. IF walksnail keeps this up i may start racing with them over HDZ.
I only run 720/100hz on my walksnail goggles with 1s VTX/cam. Ive always felt like my DJI v2 goggles with vista and 720/120hz felt way more consistent but i hated the weight and size of goggles/vtx. If this can run on my 1s kit the only complaint ill have left is the size of the lenses which are the smallest in industry. To help see better ive removed the face plate and put velcro directly on the goggles which did help but not quite enough. It also lets a little light in around the sides now but im hoping some wedges or a 3d print wedge shape with velcro glued to it will help.
the coolest dude on fpv community
Lmfao
I got my drone tag bs module and I installed it! It was a pain with no instructions but I did it and I made 3 videos on youtube.
It's certainly an interesting feature, but it's definitely getting killed by HDZero when it comes to lower resolution. The compression and light handling are just destroying the image too much.
On a side note, did the extra weight kill your PID tune? I'm hearing some nasty oscillations whenever you punch out.
Good comparison between the modes. Very clear difference in picture quality. I do think we all need to worry less about the latency numbers we watch in the corner of our eyes and have more fun flying. Just like gamers who watch their fps while playing games lol.
Low latency = High fun
Not if it looks like trash lol. WS race mode looks like analog practically. I'd rather take the 3ms avg increase in latency and see more clearly@@miquelmarti6537
I went walksnail because i think they are going to have most options, today I'm so happy i made the right decision! Ive been flying the ws 1s the most on my 2s 85mm whoop, otherwise i just liked analog for really ripping. I also hear walksnail should be having a vtx with 4k recording soon can't wait, Walksnail keep it up!!!
WS can do a lot, but it does nothing really well.
I think the reason why you can't select the higher bitrate in race mode is because it has to use a narrower band to fit into the race frequencies. So they can't use so much of the spectrum.
nice news, but what about 1080p mode on hdzero?
I'm mostly running hdzero lately, but hey.. at least they're trying.
Building a LoFlo MikeX edition wich is a real tight frame.
My V2 vtx just squeeze's in.
Gonna wit for this v3 to be available and try again ( or else it'll go in a small fixed wing).
I think 540p mode will feel like switching from a WS quad at 1080p to one of my HDzero quads with the normal cam.
Sure the HDzero race with a nano 90 will be better for racing, but a smaller quad with the WS V3 put on 540p mode... With the penetration benefit... Think caddx is on to something for freestylers that use an action cam for footage, but want the fixed latency.
500mw will be enough for most, I hardly use 700mw anyway as I fly proximity but there's enough trees and walls that need the penetration to be good.
Bardwell... I know I give you a hard time, sometimes... but, in reality, I sincerely appreciate your existence.
can you review the new iflight defender20 when it comes out?
please compare with analog (rapidfire + ORQA or DJI v1/2 DVR) and HD zero: picture quality/ and latency
Race VTX V3 FTW.
Brother I need help Please! i have a 3.5 in quad that was working perfect until i crashed it and broke a motor. i replaced the motor but now the quad acts like i have the motor output limited to 10% . it will arm and it followes the sticks like rocking it back and forth or side to side with the sticks. i have checked everything. all is set right. but no mater how much throttle i give it it is not enough to take off from the ground. i have re flashed everything and tried older versions. checked the esc's in blhelisuit. nothing makes any difference. Do you have any idea where to start> have you ever seen this before? Please help! By the way i build quads for the public so i know what im doing. but this one has me stumped. im to the point of just randomly changing parts. i thought maybe the new motor was weak and the Fc was dumbing down the other motors to match the week one so i took it off and it still does it. it never tries to freak out or anything all seems correct.
Need to put up gates and a timer when testing stuff for racing, as the biggest question when evaluating racing parts is, will this help me get either better or more consistent lap times?
You're going to need a better pilot than me before the video system makes a difference in my lap times.
Is the displayed latency accurate now? I was of the impression that it was usually showing less.
This makes Walksnail the universal and flexibility king ! And in the golden middle position. However, if you want the best 1080p and the fastest latency, you probably have to go with DJI o3 and HDz and walk around with 2 goggles and 2 quads...
I like the comments about not seeing details never raced anolog only. F that, anything better than anolog has my vote
I think this needs a side by side with HDzero
hahahahah I went back too analog the Rush tank 1.6 watt vtx is incredible with the new cameras and the penetration blows any digital away not clarity but man the blocky dji in trees is bad ,, almost crashed trying to fly through trees with DJI far away more open stuff where as the Rush Tank screams barely any static its crazy , DJI latency after flying 1,6watt analog you can really tell the difference ,, and I love digital too 😭😭😭😭😭
I'm confused, does this mean I can use my Fat shark Recon V3 analog goggles??
Anyone every have a whoop seem to lose thrust later in the pack for no apparent reason. First 1.5 minutes it flies amazingly, then suddenly feels like it barley wants to go. So, I have another identical build and it flies great all 3 minutes. I’ve tried new motors, reflashing the firmware, escs. I’ve also flashed the other boards diff all over . Even tried brand new lipos. Nothing seems to help. Possibly board going to shit?
The resolution doesn't have to be great for racing, but you need to see the ground instead of that fuzzy camouflage blob. Anyway WS will be a no-go at any race event.... because the googles do transmit and will disturb any other pilot nearby with sharp interferences. I feel such a basic point should be mentioned in this video.
Why don't use ws 1s module for race setup? It's smaller and lighter. You can install pro camera or v2 micro.
In my opinion, it won't have enough durability to stand up to racing.
I would be curious to see your experience with HDzero 1080p mode. I hear the latency is higher, but it's also fixed. It would be a nice comparison between two systems which both give you a choice between resolution and latency
Isn't that 30fps only? That would give more latency than this
@@Martoriass from what I understand it is 30 ms latency. You wouldn't use it for racing, but I don't see walksnail as a viable racing option either. The fact the goggles still transmit would be a nightmare at a race.
Most of the reviews of HDzero 1080p come from people who usually use HDzero and prefer lower latency. I'd be curious to see what a pilot who uses variable latency systems thinks
@@rhyswyber797 man if you have to ask what his opinion of that would be I'd have to assume you don't watch him much lol. no offence but jb doen't like hdz.. i know i know he tries but he hates the system yes I used a strong word
@@rhyswyber797 33ms from the framerate alone + something for processing so yeah sounds about right. I haven't tried it but from gaming at 30fps I don't think it would feel good but then again, maybe works better for fixed wings etc?
Just tested it myself...... Feels good.
And image resolution reduction i thought would be ok.
However the compression is dreadful, really makes flying over grass look terrible.
Hdzero need not have anything to worry about.............
You say we can have 1080p... I have Walksnail on my Hdzero goggles and 1080p is a stuttering mess......
ASUS TUF Gaming Video Capture Card still not cheap but will work at 100Hz
Does everone knows if these affects the fly on the Fatshark Recon HD with 60 fps?
The reason for “Standard” bitrate only is that high bitrate is twice as wide - which is why you only get 3 channels. This is not race friendly since you cannot fit a double wide channel into a racing channel.
Hdzero looks soo much better
So if race mode is locked in at high frame rate, does it mean that it won't work with vrx modules on hdo2 goggles?
I think so. Because the goggles can't use 100 fps.
I believe that not having props in view will have an effect on the latency. Since the firmware has to re-render that area with every frame
The complexity of the scene does not affect the render time at all. The render time is always less than the framerate. If the framerate is 60 fps, then the system must send one new frame every 1/60th of a second.
@@JoshuaBardwell I might have worded it wrong, sorry (english isn't my first language).
But the image in that area contains new information that changes with every frame, even if the copter/scenery is standing still.
Wouldn't that affect the image transmission?
Rendered image fogginess maybe, latency not.
When they all now gonna implement 2 modes they maybe need to bring out new optimized hardware on market. So i'm happy i have still not invested in digital....
Help.........i was update firmware my walksnail google, and i fail update it, now my google just boot loop freeze in screen, please hekp me 😢😢😢😢
A big issue with DJI was not the latency ... Race organizers don't really care about what latency the racer's themselves have. They care about the systems playing nice with each other. With DJI, the big issue was that the Goggles would interfere with other racers in the line. Is this also an issue with Walksnail?
2:25
This is your answer.
Not anymore.
@@jaysonrees738 That's just the frequencies. What I am talking about is the Goggles transmitting. There should not be any RF being transmitted from the pilot lineup.
@@oneeyefpv I guess I didn't consider that. Not going to run the tests myself as I've already got too many things to think about, and I don't do any racing myself.
Yes the Walksnail goggles also transmit. The workaround is to move the pilot farther apart. This is something that some race organizers have solved, but not all want to go to the trouble.
Fixed latency and changing the frequencies to be more Raceband-like are not the only issues for racing.
Timing systems miss laps with DJI, as it has something to do with blips of public channel. Does WS not suffer from this?
Also, as you realized, getting DVR is problematic with either DJI or WS.
People who race tell me that WS output power is consistent and does not have the same issue DJI does with dynamically changing and screwing up the timing threshold. The goggles still transmit (like DJI) so you need to space out the pilots more to avoid interference.
@@JoshuaBardwell Thanks for the good info!
Notification bell definitely works!
YT: "11 seconds ago, 1 view"
Why do cameras show more motor on the left. Am I the only one that notices this
Hdzero is king ❤
Looks like a good analog system, just slower 🤭
No range comparison?
Guys so basically, if I'm using the Walksnail VRX with a SkyO4X or an HDO2, I basically can't fly in race mode?!
sounds like your props are bent or pitched too high for the motors
Still better than analog 😊
If you need to go down to 540p, it makes me think video quality won't be much better than analog. So is it worthy?
You can judge for yourself. There's sample footage in this video.
This is strange because according to legato website the cam link 4k can support these settings
3 840 x 2 160 up to p30
1 920 x 1 080 up to p60/i60
1 280 x 720 up to p60
720 x 576p50
720 x 480p60
Yes, and 720p @ 100 fps is not compatible witht he listed settings. But it works.
@@JoshuaBardwell good to know. Thanks
Are there many trees, branches and bushes on race tracks?
Not sure I would lump dji into the haze issues. I know it is there to some extent, but it is FAR better at resolving things than walksnail IMO.
Would this work with the standalone vrx on hdo2?
No because HDO2 can't take the 100fps signal.
@@JoshuaBardwell that's what I was afraid of 😢
Now Imagine what hdzero could do with a non fixed latency
That will probably never happen. It's build with fixed latency from the ground-up. What we could see is a new High Latency mode, but it will be fixed latency.
I hope its possible, more versatility from each system is good.
@@Voyajer. For variable latency the googles would need to transmit, wich don't. To me a higher fixed latency would be more interesting.
Fixed is good in my book. At the end of the range I'd rather see some snow than have stuttery sticks. YT can't show that.
Could I pay you twenty four bucks for a year sub or would I have to pay in monthly increments?
Currently the only way to sub is monthly, through patreon.
Can you elaborate on the analog the new 34.??.?? Is saying it has I'm interested in sharing walksnail with non fpv people with a set of analog goggles is this a possibility
No it's not possible. And it won't be possible. Unless you run a hdmi cable into the analog goggles.
@JoshuaBardwell then y does it say analog in the new system update weird I new it was a long shot but thought I would ask. Side note a video on how to share walksnail with others would probably be a big hit in the community just saying thank you for all you do you are amazing
It just means the WS channels are now the same frequency as analog raceband, not that WS can receive or transmit to analog goggles.
My understanding is the 1s or lite version3 should be a game changer due to the voltage requirements should be as high as 13v. I will be a total convert if this happens for real
Yep 3.1 - 13v range.
Yeah it's true plus it's got 500w output now too
This one is still too heavy for what I need. The v2 still puts me at 258g. But some of that is the tpu sled I needed to draw to mount it. But, on 2s, I don't need to worry about dropping below 7v or 6v LiIon battery power. Wish I waited a few more hours before hitting the rdq order button yesterday
Maybe decasing it?
@@Mupshot Do share your findings once you decase it . I'd be very reluctant to de case this because it can theoretically go up to a higher transmission power, and i don't think that will go well with the durability.
11:52 there was 1862291ms of latency :D
Wery racemode
There is a new version. 😆
I really don't think you feeling higher latency with standard mode (even when the output doesn't show much difference) is placebo.
Way more likely that the walksnail goggles are not reporting latency accurately. And even if it were "accurate", they could have 60 fps reported at only, say, 10 Hz, which means each report is 6 frames put together and if they've just used averaging, then the latency in those spots might actually be a set of "23, 22, 23, 23, 100" or something that averages out to 33ms which then ends up being what they report. But that one frame at 100ms latency - and usually right in a sharp turn where you most need low latency - would definitely affect you.
Standalone vrx on hdo2 worx?
Yes
Sir, you’ve inspired me to build my own F1 car just to make sure Lando Norris is better than me at racing.
Jesus. I just bought a V2 receiver and bow i gotta buy a V3. Damn this hobby.
You really don't. Just keep using the v2.
Im not getting whatsmell
what is the frame name/model ?
533 switchback
Since you took the effort to show how the vtx did not fit then why not around 9:42 show us your solution? I wanted closure. I wanted to see your solution. I don’t know how I will move on from this part of the video.
I switched to longer standoffs to raise the top plate.
Walksnail bringing you “Analog Mode”
I fly for fun, It doesn't look fun to have a terrible image in my goggles. I don't care if the latency is so low it takes me into the future, if the image looks that bad I don't want to go!
low latency is good.
@@nedstudtlow latency is good, yes, but a great image is also good. I'll definitely try the race mode to see if I notice any difference in flight, but I'll be sticking to 720p 100fps in the long run
Latency that take me into future ;-) rofl... but constant is good... I have both and is a terible pilot but still think hdzero is more direct k a quad. But walksnail has for sure better penetration. The blured gras is a bit anoying on walksnail... so my choice is hdzero for quadz and walksnail for planes..
having variable latency gives you better image but your sticks will gitter at the end of the range, having better latency gives you more control but the image will get snow. I preffer control and you should also. But I get why new people that were not even exposed to analog have no clue about what a low latency system gives. Also that DJI-like sharp image is a very good advertisement, as most of us discovered fpv by watching youtube.
the only mode I want to see is "don't be a dick" mode. I love flying digital, dgmw, but I've basically stopped even bothering to bring my analog birds to group flies, because they knocked out EVERY TIME now instead of once in a blue moon back when the system was just yelling out what channel you're on.
DJI O3 Auto mode is "don't be a dick".
I am on your team 😅
@@JoshuaBardwell dji03 auto stomps all over analog 25mw. I tested it in the spring. It's better with analog 50-100mw, but we race at 25mw
and by better I mean you can get a couple guys who don't mind horizontal lines all over their feeds to fly with the dji guy, but it's still shitty.
Not to presume, but if you're seeing horizontal lines, IMO you're putting the DJI pilot too close to the analog pilot. DJI goggles transmit, so like any transmitter, it doesn't matter what frequency you're on, if you're up in their face, you will get stomped. Analog works the same way. The DJI pilots need to be about 15' from any other pilot who is in the air and the lines go away (in my experience). Where I have seen this issue is if the race organizer puts the DJI pilots in the same seats as analog and therefore they are 2' away from the analog pilots.
As I just decided to pull the trigger and bought a bunch of HDZero gear a month ago, you're all welcome. 🤣
One day dji will also make a race mode 😊
🤣
its evolve but in reverse go back to analog better price
Am i the only one experiencing really low frame rate? looks like you recorded @24p with visible shutter
The latency is an improvement, but the mushy picture is terrible, at least from here - IDK how good it looks through the actual goggles.....
Can't get dji in the US anymore. it has been blacklisted. Can't buy the FPV goggles
That's completely untrue.
@@JoshuaBardwell thanks for the reply. Their website told me that tis product isn’t available in my region. When i tried to order the goggles.
Hello Josh. I just want to i update this post. I found out that the only certain goggle is not being sold in the us due to rfid requirements. Thanks
the video quality seem not good. they focus only to latency .
What sucks is the older we get the less we notice latency...
walksnail looks like trash imo... especially with this vtx in 540p, ive never been a fan of how walksnail video looks but great video on it JB!
High bit rate is likely disabled because it uses 2 channels to get the wider bandwidth. And JB can you stop misinforming people about WS and DJI latency being due to them restransmitting video frames. No realtime video system does this! The latency is simply due to dropped corrupted frames. HDZero has the ability to display partially corrupted frame hence the stable latency.
I wanted to be sure I wasn't spreading misinformation so I went back to Walksnail and asked their engineering team to confirm. I asked, "Does the Walksnail system retransmit data," and they said, "Yes, the Avatar system will do that. Goggle asks vtx to resend lost data on lost data."
Thanks for the opportunity to double check.
@@JoshuaBardwell apologies, in retrospect I was out of place there to suggest you're spreading misinformation. Thanks for following up with Walksnail on that and providing clarity, and also the humility with which you've handled my critism. This really does come as a surprise to me because coming from an communications perspective, realtime voice/video streaming protocols like RTP are generally transported over UDP (which unlike TCP does not retransmit) because they prefer low latency over reliability. While protocols like RTP can themselves implement retransmission on a per usecase basis, in a bandwidth constrained wireless application like FPV I wouldn't expect that to be the case. Especially given the fact that the system adaptively reduces video quality/bitrate (I.e. the smearing) to respond to reduced bandwidth due to reduced link quality. Retransmitting failed higher quality video frames over a link with reduced bandwidth makes no sense to me. But I guess we're just going to have to trust that the person at Walksnail actually knows what they're talking about. 😅
Quite prophetic of uou to say a new firmware would come out as soon as you record. The newer 35xxxxx firmware is a bit better than this
Maybe so but that's what happens when Walksnail releases new firmware the same day the product comes out.
Yikes with image quality like that you might as well fly analog. HDZ delivers the lowest latency with a much better image at a similar price than snailsmear.
