Which FPV goggle works best with Walksnail vRX? I tested them! 

A good way to test digital? How is 46ms latency a good way to test digital FPV? You really think you'll like flying with 46ms BEST CASE SCENARIO latency? Like JB said, that's the least you'll ever feel and most of the time, when actually flying FPV, you'll be getting 10 - 15ms more latency...so, more like 56 - 61ms latency in actual use. Not flyable really unless you just fly wings. Also, the 04X's cost $529.99 and the OLD price on the DJI V2 goggles was $569.99 with 4 antennas and a battery. So, how did you feel the V2's goggles were an "absurd price?" At least you would have gotten BY FAR the best image quality, range with clarity, and penetration digital FPV has ever achieved...and for only $40 more than what your 04X's cost. But, would it have been more when I don't think the Skyzone goggles come with antennas or a battery. Plus, the new price on the V2 goggles is only $429 USD! Just so ya know, that "breaking of compatibility with older products" is old news! DJI now supports forward AND backward compatibility with their new 03 digital system and the Vista/Link VTX's from the past. Both the V2 goggles and the Goggles 2 work with both of these VTX's. Full compatibility and then some added little features we weren't expecting but DJI gave users anyway.

@@KOrnhOliO1 For me the latency is fine, skyzone's came with everything I needed, except battery, but u can use a powerbank. When comparing the price I also took into account the transmitters, they are notoriously more expensive than the analog counterparts.

@@KOrnhOliO1 I also went with the sky04x instead of dji because of the RIDICULOUS price. Back then the DJI was 600+ eur and I managed to snatch the sky04x for just a bit over 300 on a sale. New price of dji for peasant europeans is still 570eur = ~625 usd. The DJI compatibility means they connect but based on reviews I have found then the Goggles 2 with vista are utter shit.

What's about the latency? I also have a pair of 03o s laying around. Can you recommend the setup?

@@elogamer102 definitely worth a try. I'm happy

How do the OG HDO goggles handle the 16:9 input? The HDMI specs say they support 4:3 input over HDMI (which matches the screen dimensions). Does the image get stretched vertically like in the Skyzone SKY04X goggles (when those are set to HDMI 4:3 mode) as shown at time position 4:07, or do the HDO goggles automatically letterbox the 16:9 image in their 4:3 screens?

@@snowleopardfpv Surprisingly they handle it pretty well. It is automatically letterboxed with the VRX is set to 16:9. When set to 4:3, it gets stretched pretty heavily but that’s expected.

Thanks for the info friend! Been trying to find what people's experience with OG HDOs is.

@@greatmanofscience Glad I could help! Coming from analog it’s night and day better performance. It’s definitely not up to the standard of my buddies DJI V2 goggles feed but I’m more happen than I expected from the setup.

You still reading this? :-) So, I have the skyzone 03o which also ONLY does 4:3... So you set the vrx to 4:3??

Because they both run at 60fps there isn't any difference in latency from the vrx side. Only the goggles might make a difference.

Would quality of the hdmi cord play a factor? I.e. if I use certain USB c to USB c on my black magic pocket, it won't record frame rate correctly.. (lots of dropped frames) however an identical looking cable, though slightly thicker, gets the job done.. something to consider?

Quality of the HDMI cord won't be a factor. Either the digital signals get there or they don't.

@@JoshuaBardwell how about if adding an elbow connector to just tidy up the wiring a bit so I can set down the goggles on a table.

@@BabaBlacSheepFPV same logic applies. Either the data signal gets there or it doesn't.

Same here

I don't think the 4:3/16:9 option changes the aspect ratio put out by the vRX. It was originally put in the menu to control the aspect ratio of the camera, but it's been a "dead option" since Walksnail has never made a camera that supports 4:3. I have tested it in the past, and I tested it with the vRX, and in all cases, it seems to have no effect.

but now the DJI V2's are $200 refurbished or store demo 120 fps vs 60 fps stretched screen I dont Know I went with DJI V2 and Falcon Vista 120 fps under $400 I use the SkyZone O4L analog and love them but to get walksnail with LCOS screens would not make sense same screen's as the DJI V2

It definitely doesn't look smaller to me, when looking in the goggles.

But it *has* to be smaller... since when displaying a 16:9 image, a 16:9 native screen with 46 FOV stays 46 FOV, whereas a 4:3 native screen with 46 FOV will have a smaller FOV due to diagonal being smaller. In this regard HDO2 and O4X would be the same but HD0 would win for biggest FOV @ 16:9... no? however, the real question there is how much difference do those 4 degrees really make?

I think the real question is how accurate even are the manufacturer quoted FOV values

@@pfeerick It doesn't make a huge difference. I tried to post the link to the FOV comparison tool but my comment gets deleted everytime. You can search for Oscar Liang FOV comparison tool. Its really easy to compare FOVs with that

@@nzmfpv I also like the FOV comparison tool, but you have to take it with a grain of salt. It takes manufacturer reported FOV as accurate and then runs some math. There is also value in putting a camera in the screen to show the actual effect of the optics etc on the FOV.

even with hdzero vrx the cobra x latency already 50ms.

@@moesotaku Yeah, but I'm not going to buy a 800$ (CAD) goggles just to fly only Walksnail. It's also why I went with the VRX. I wanted a cheap entry point to see if I would be interested. I already have the HDZ goggles preordered because I know that's going to be my jam for HDZ and Analog. Walksnail is just going to be something on the side, and there's a good chance they can improve the encoding rate or transfer delay.

I'm in the same situation!!

Did you find that you get an extra black line on both sides of the image, further reducing the image size? (Not just the letterbox lines at the top and bottom which are expected because of the 16:9 image on a 4:3 screen, but also on the sides of the image.)

@Vousie I did not see any reduction in image to the left and right of the screen. From the v6 view, only the top and bottom were cut off due to the 16×9 presentation, but as you stated, that is normal. I wish there was a way to add an image to this thread.

@@neopro2783 Hmm, having checked again, I wonder if it's a compatibility issue with my laptop. When I just switch it to HDMI mode without an input, the blue image covers the entire 16:9 area in the goggles, yet as soon as I plug my laptop's HDMI out into the goggles, the image is slightly smaller (i.e. it adds a black border all around the edge of what was blue before)... This is even with the laptop set to only output to the goggles. Edit: Huh. Just tested it on a second laptop, and that one did cover the full 16:9 area... Looks like it is a compatibility issue. Now to figure out how to fix it...

Did you happen to try out your EV300o?

I've only managed a few flights with my vrx and the CobraX v1. The numbers don't lie, but as wing guys it's not as big a concern. I've had no issues

I have some Dom V3, no issues at all with the walksnail ?

I do take averages, but the latency measurements are always within 2, or in rare cases, 3 frames of each other, and the average is usually the same as the mode. In other words, a typical data set would look like: 10, 10, 10, 9, 10, 10, 11, 10, 10, 10, 9, 11, 10, 10, 10, etc.

@@JoshuaBardwell Great explanation, keep your hard good work... 😉

I don't think that's correct. The 4:3/16:9 option is supposed to be for the camera, but has never been implemented. Walksnail doesn't sell a camera capable of 4:3. It's just a dead menu option that has no effect.

@@JoshuaBardwell this might have only changed in the latest firmware update but I've actually toggled the setting in the camera sub-menu of my VRX and seen a visual change. The 4:3 option just clips the width of the image.

It can’t do 4:3 right… I have a stretched image under both settings in my Skyzone 03o’s. I can’t fly it despite trying to get used to it.

Anything that relies on an HDMI capture device will have too much latency to fly off of.

That best case latency, from the chart, and then adding 10 - 15ms for flying FPV and you'll get the idea that really high latency is going to be a huge concern.

Personally I wouldn't find that setup very usable due to the additional latency.

@@JoshuaBardwell thank you for your attention. And saving my $ 350 . 😁

did you check? i thinign about VRX to my skyzone 03o but not sure if its gonna work well

@@MrrQuake its been working really well so far

I too have the Attitude V6 been looking for that info also...

Joshua, I believe the above comment is phishing. Can you delete and ban?

I also have the FXT Viper goggles V2 and have been wondering how they would work with WS. I'm somewhere between beginner and intermediate flyer so nowhere near the racing and free style you see on YT. Probably closer to beginner. Wondering what you get for screen size, latency, etc.

Commenting to see any replys on this.

The latency shown on the DVR or the sensor to display latency? You can reduce latency over HDMI by inserting more fps into the channel.

What do you mean? 42 ms vs 67 ms for the HDZero goggles...

Those goggles were loaned to me by somebody so I don't know the answer.

I was hoping the Dom V3 was going to be included.

But, remember the latency would be sky high!

aren't they 800x600 o.O

also work on aomway commander v1? thanks

Yeah unfortunately the set of Dom HD3 that I received wouldn't take any HDMI input at all, not even from a laptop computer. I sent them back to the owner with my thanks, and he said they immediately worked fine for him. I have no idea why.

@@JoshuaBardwell I had a similar problem with my Dom3s at first. They won't work until you flip the little switch to turn off the analog module. Works fine now. I just flew with them 10 minutes ago. The FOV still sucks compared to others but it was super clear. I'll happily use them until my HDZero goggles get here in March

@@gadgetmerc oh man, you're answering my question! I've got the old Dom V3s, and I was curious how they'd hold up. No issues? Latency isn't a deal breaker?

@@MoonManMetals I don't feel latency until i go behind something. Feels like it drops off a cliff fast. I assumed it was due to the shit walksnail antenna. I'll test with slow-mo and an LED tonight. I'll follow-up here.

@@gadgetmerc you are absolutely the man. Are you running with their antennas on both the VTX and the VRX? Will you bother upgrading, what with your new goggles coming?

Yeah I think people are just comparing them to OLED screens, but when you are using them, they are great. You camera compresses the dynamic range so much you lighten the shadows and darken the highlights that its not like you can see more with OLED. Its a just a reviewer issue. The Cobra X screen is great.

I have both the Coba X and the X2. Only power supply board and DVR of 30 fps vs 60 fps are different. I'm quite sure latency is the same. The Cobra's have 7 image modes and the brightness, contrast, saturation, hue and sharpness can be adjusted. I do not recognise the dimm picture of JB's Cobra X2. Love the vibrant picture of my screens, many hours on them. For sure they cannot deliver the same picture as the Oled screens, but it's not as bad as JB's picture 😊

Yeah for sure!

But, as you probably know, the latency is most likely right around the BEST CASE SCENARIO on his chart of around 75ms latency. Like JB said, that's the least you'll ever feel and most of the time, when actually flying FPV, you'll be getting 10 - 15ms more latency...so, more like 85 - 91ms latency in actual use. Not flyable for FPV really, unless you just fly wings.

@@KOrnhOliO1 I can't give any numbers. I was using EV900D as analog years ago and I felt the latency. And I was flying them as analog goggles few times recently since my friend is having them. There is a setting deep in the menues where you disable certain option and after that there is less latency using them as analog goggles. I definatelly felt that. Latency was still big (for analog), but it was better. And I was flying them recently since he bought Walksnail vrx and there was less latency for sure compared with using them as analog with that option disabled. I would say little more than using high quality with DJI. I would definatelly pick that over analog. And again, that gigantic 1080p lcd screen in there is the best looking lcd screen I have ever flown. And I did flew a lot of various fpv goggles. When Walksnail sorts out zoom out option it will be even better. That is, if you can live with 50+ ms latency.

@@mihavuk That is, if you can live with 50+ ms latency...that is gonna be a tough pill to swallow for many. 😟

i also would like to know, i have skyzone 02c also ...

Yes there are lots of other videos on YT io people flying proximity with Cobra X's with Avatar VRX's I think JBs sample size of one makes these tests pretty useless but are appreciated. But either way his cobra X's he tested seem to be an outlier.

So after flying with the Avatar HD goggles for a few months I decided to go back and try my CobraX + VRX combo. It definitely felt different for the first couple packs but after that I was doing all of my normal baby-freestyle stuff so I think our brains are able to compensate/adapt as necessary. I'm keeping that combo as a backup now. The CobraX aren't as comfortable and I have to wear glasses with them, so not all great.

@@LargeNuts I'm thinking the closer you are to being a top pilot, the more this will matter to you. But for us mere mortals - probably not as big an issue as being discussed :)

Remember, the GoPro exposure was calibrated to the OLED screen and was locked, to give a sense of the difference between them. This is how much brighter the OLED is.

Yeah I tried it but it was not a usable image.

This is v2, but the only difference between them (if I recall correctly) is the 60fps DVR on the v2. The display is identical.

If you're happy with the brightness of your Cobra screen on analog, then it won't be any different on Walksnail. Mine was dimmer than the other goggles I use.

@@JoshuaBardwell Cool thx JB. Guess the latency is the only thing that's really worrying me now.

I think I address this in the video but maybe it got overlooked. The HDZero HDMI input is still being optimized. The 720p100 input signal was first to be optimized. The 60fps inputs are still not optimized and have higher-than-expected latency, which is planned to be fixed in future firmware updates.

@@JoshuaBardwell But as of now, HDO2's have as good performance on 60FPS as hdzero does on 100FPS, so saying that hdzero is the best choice to run walksnail is not true, yet...

@@JoshuaBardwell Yes, but if you just look at HD Zero 720p100 and HDO2 720p60 they both finish "delivering" the image at ~41 ms. Now, at 60 fps an image takes ~16 ms to refresh. At 100 fps it's only 10 ms. So to finish the picture at the same time, the HDO2s must start "delivering" the image 6 ms earlier, meaning their HDMI link must be faster. Or am I missing/overinterpreting something here?

And just to make that clear: this is not meant as a negative comment on the HD Zero Goggles (I still think they are the most interesting goggles on the market right now and I will pre-order them in the next two days) I just think that's interesting and maybe there's still a little bit of potential for improvement there.

I think that the latency measurement of HDO2 vs. HDZero is not as significant as it seems, because of the limitations in my test method -- the ability to only measure 4 ms precision and not to be able to distinguish between first-pixel and full-frame latency. This is the best I can do, and I disclose that and show the results I get. But if you look at Chris Rosser's results (with 1000fps camera and 1 ms precision) then I think you would see something different.
