4 Miles of Walksnail
ฝัง
- เผยแพร่เมื่อ 22 ม.ค. 2023
- I mounted the RushFPV Cherry antennas to the Walksnail VTX, and took it out to 4 miles. The Eagle flew great despite the wind. Walksnail made it out there and back just fine, but I don't think it has a whole lot left in the tank at 4 miles... lol I was hoping for a bit more, though I am still at 1080p. I think dropping to 720p will give it a bit more headroom, and we still have the Tripple Feed Patch arrays I can mount up to the receiver, rather than the smaller TFPs on it now.

Fantastic flying, Keith! 😃
I'm really liking this system! The image looks great!
Stay safe there with your family! 🖖😊
Amazing ,love it that you did it in 1080p❤❤

I did 5.3 miles yesterday with my aeroscout and walksnail system, using the same antennas your using on the vrx but I have some lollipop 4 on the vtx , got back home I was in the air for 23 min , flew another 8min around home on stock setup , 3400 li ion pack
What bitrate and resolution are you using? I think the consensus is pretty much that you get better range on 720p at 25Mbps. I'm still at 1080p for now, 25Mbps. I honestly don't see a ton of difference in picture quality between 720 and 1080 unless I pause the video and look close at the fine details... That's ground testing though, might be different in the air.
@@bonafidepirate I'm on 720p 25mbps , 1080p is noticable in the goggles at least I can tell
@@bonafidepirate is that overlay tool something you install on the goggles?
@@jimmytheriot8978 The overlay took takes the files from the VRX/Goggles SD card, and puts the OSD onto the video file. What you see here is the HDMI output from the VRX recorded on my PC, no overlay tool used for anything.
Here's a demo of how the tool works th-cam.com/video/Geou1lFER_g/w-d-xo.html
Im a FPV Drone pilot but i totally enjoyed this video, well done mate!!+❤
I found it to be absolutely critical, to have both high gain patches facing the plane. One on an RX port and the other must be on the TX port of the VRX or goggle. To maintain maximum signal strength, and best range.
I'm using the VRX, and have my two TFP on the top ports, built in patches for the other two antennas. One of the top ports is the Tx, they're all aimed together and pointed at the plane as best I can get it... lol To be honest I think I'm just kind if finding the limits while flying with the lower gain antennas (as opposed to TFP arrays or something else relatively high gain) and staying under 400ft. With more altitude I could certainly go farther, but we'll save that for another time, and place... ;)
you could build a little antenna pole at the loveshack ? every meter above ground makes for a better reception and fresnel zone,innit ? crazy flat outthere btw - i only have hills and valleys around me here :)
Probably worth bypassing the internal patches which are probably crap anyway and putting two more sma connectors on there.
But honestly i would expect range to be better on 1200mw.
I hope the VRX is not less sensitive than the goggles.
I've had my VRX doing the business at 7.4 miles so far with two 150mm triple feeds and the stock patches. Another couple of TF patches on SMAs would deliver mad range, like Wesley Varty's findings.
Thanks!
This is very much appreciated!
I flew my quad yesterday on just 200mw with no issues. Betaflight of course but absolutely no flickering of the OSD. I am using the overlay tool from GitHub though to render the video. Maybe the flickering is because you're recording the live feed directly on your PC?...The HD feed has opened up a new world in terms of detail. Imagine what overhead Summer sun will bring?
I noticed the onboard video memory ran out again...😳😏😏😀😀🇬🇧👍
I've played around with Kirek's OSD overlay tool a bit, the flickering is there too. It's flickering while flying live on my monitor as well. The recording just records what the HDMI is pumping out... lol It doesn't seem to be related to low signal or whatever, you can see it when the plane is sitting on the runway, before and after switching to low power standby mode.
Oh and that small onboard memory is one of the first things I suggested they change when submitting feedback to Caddx! lol More storage or an SD card slot. 8GB is not enough for planes that stay in the air more than a few minutes. For now I'm happy recording on the ground though.
@@bonafidepirate Maybe the flickering is an Arduplane thing then.?..I don't think the cherry antennas made a huge difference?
Great to see it all working though...I'd like to see some Giroflow stabilised footage using the blackbox SD card data at some point in the future? Be a good video subject IMO. ..🤔😳😀
I don't have any flickering with the latest betaflight
@@MachuPichuu Mystery solved, his flickering was caused by the onboard VTX DVR recording...see later clips...🤔😳😏😏🇬🇧
If you decide to put it on the AR Pro, I’ve designed a nice little 3D printed bracket for the VTX and antennas for the “HD hatch”. If you want, I’ll put it on thingiverse. It’s designed to take it apart very easily if you want to remove it or move it to a different plane.
Yeah for sure! I bet other will find it useful too... lol
@@bonafidepirate I'll upload it tomorrow and share the link. Bedtime now... 😴
Curious if the video receiver was setup outside on a mast or something. Impressive how the tech has evolved in recent years.
Yeah I always have my video receivers outside. I doubt you'd make it very far with it indoors... lol I have a 25ft HDMI cable, the VRX sits on a tripod with a battery powering it.
kinda seems like the stock tx antenna arent as bad as they used to be. cherry's did about the same range wise eh?
There wasn't a ton of difference I think. Maybe one day I'll drop the power back to 700mW and fly that same 2 mile path where I was starting to get some loss of quality and compare.
For more range just fly at higher altitude? Maybe objects in the way.
Yeah more altitude will definitely give you more range, if nothing else just for not violating the fresnel zone... lol I'm just looking to see how this performs in the same way I fly 1.3G analog really, which can definitely fly farther at less than 400ft despite the larger fresnel zone with it's lower frequency. The better penetration makes up for it in that case I guess. Honestly 4 miles under 400ft isn't terrible for 5.8GHz, even more so considering the bandwidth used for HD.
Almost as good as tye old fpv blue hey!? :)
Keith, is that pan and tilt on head tracker or just radio dials?
So far, this has better image quality and a bit less range than I got with that one. It's certainly smaller and easier to mount on smaller craft... lol I know I've seen others getting more range than I have though, so that may be something I can remedy.
@@bonafidepirate yeah se certainly are very spoilt with all this digital systems, I'm on DJI and the new o3 looks beautiful but at the moment not much for osd!
@@rotormasher The biggest reason I never picked up DJI was the lack of a stand alone receiver. I think everyone would be surprised if they made one at this point... lol BTW I missed the bit about pan/tilt before. It's on the sliders on my radio (TX16S) no tracker.
@@bonafidepirate I know it's like Apple, they want you to get you heavily on their system.
But I think in terms of image quality there's nothing else like it 😜
so i'm new to fpv...i'm on the verge of buying the new hdzero goggles that aren't even released yet($500)...opinions? bad idea? i like what i see in this video...and this is about all i ever want in regards to a flight experience; perhaps another mile or two out, at most.
i currently have no fpv gear whatsoever, just a new/unused matek flight controller.
I pretty much never fly with goggles, just monitors, always have. So I can't comment much on the goggles, but everything I've seen lately seems to suggest most people that have used them like the HDZero ones. For just starting out, I'd say build something cheap and fly it and see if it's something you want to dive deeper into. On the other hand, nice gear would be easy to resell later, and if you stick with it you only have to buy once. There's always two sides to every story... lol
on RX was only omni antennas, is it correct?
No, no omnis on the receiver, the two built in patches in the VRX and two small TFP on top.
The 150mm TFP antennae should at least double your range.
Yep, but at the expense of a narrower area to stay in while flying. I have two of them that I'll try eventually, but always liked the "beam" on the smaller ones. I fly with similar gain and pattern on my 1.3G antennas for the same reasons.
@@bonafidepirate Have you considered the SMA installation hack on the VRX? Seen a few people do it but I'm a bit scared to butcher my VRX at the moment. Would be interesting to see how 4 triple feeds worked if the additional pair were angled out slightly for a wider beam.
@@wattage2007 Yeah I've seen some people removing the built in lower antennas and replacing them with SMAs. I'm more interested to see how good it can work with minimal modification first. I haven't even mounted the large TFP arrays yet, still using the smaller lower gain ones.
What's your altitude above sea level at your location
About 50ft, so pretty much at sea level
Bonafi you have to help me. I want to buy walksnail VRX but I dont want connect to my analog goggle (skyzone)
I want to conect with HDMI to my cheap FHD 12inch lcd monitor. Will this work?? I fly long range like you only so bigger delay is no problem but I want the full potential of the image ( 1080p) . VRX will be above my shed roof around 1m so I need 3m HDMI cable
Thanks
That should be completely fine. I'm using a 25ft HDMI cable ran back into my shop, and I have a HDMI splitter to connect to my PC that I record with, as well as a small monitor used to fly with. Works fine for me!
@@bonafidepirate great :)Can you tell me what HDMI did you buy....any link ?
@@nucleo1772 No sadly I dont... lol I bought it in 2017 when using the fpv.blue system. I looked back at my old orders on eBay, and the listing is gone now. It was just listed as a 25ft HDMI 1.4 cable for $6.95 with free shipping, so it can't be anything special. ;) I'd guess any decent cable should work. You'll need an adapter, the HDMI connector on the VRX is a mini size, not full/normal and not micro. This is the adapter I have amzn.to/3R4PAOG
@@bonafidepirate thank you so much :)
I did 17.8 km for now, here is my 16 km. Preparing better plane and battieries to go beyond 20km
th-cam.com/video/fHHXh9k-SGg/w-d-xo.html
I saw that flight, I think in the Hooligans group... lol Are you using 720p or 1080p? Mine is currently set up at 1080/60, 25Mbps, and 1200mW. I think if I drop to 720p it will do a bit better with more headroom for bandwidth. I haven't tried 50Mbps yet either, I assume that will demand even better signal to try and maintain that bandwidth over two channels at the same time. I could be wrong though! lol Is your video the files from the VRX or VTX? I didn't see any breakup at all there.
@@bonafidepirate i subscribe your channel since i saw you had Binary, which i recently had bought. Before that whatched a lot of vids ♥️ i am suprised that you remember my video!
Its gogles DVR, 720p/50mbs/1200mw, i had a little break up while returning home ;)
@@bunk.w420 Watching again now I see when it was breaking up a bit. I forgot the VRX/Goggles just throws out the bad frames and skips over them... lol It doesn't show as much as in real time when the video pauses for a bit before coming back.
@@bonafidepirate yeah, and also doesnt show pilot standing with gogles on face and heart attack in chest if video comes back😂
@@bunk.w420 lol Yeah, it's a bit of a strange feeling at first when it freezes. I think I'll start playing around with bitrate and resolution next.
