@@APS-yo8oy Yep exactly! I tried HDZero and didn't care for it, as it was marginally better than analog. If you are flying quads than I can absolutely see the advantage as even a bit more res is better than analog especially when navigating gates at 70mph, but for fixed wing it's a hard pass. I have flown the same 90mm Viper with DJI and a custom FC from Blackstar and this summer converted it over to a FC with Walksnail and INAV as I like the OSD better and INAV is just more capable. I absolutely disagree in regard to the latency argument and would counter the only time it would be important is during takeoff and landing, which on a Viper 90mm is 30-35mph so a non issue.
If your brain can feel 25ms of delay you’re not human. I’d take a tiny bit of extra latency in trade of superior range, penetration, and superior video quality. Pilots have been installing the DJI air units with head tracking for years. This isn’t anything new
@@APS-yo8oy I've been using DJI for a few years now and the latency -vs- analog (for example) is 100% noticeable and I doubt many with experience in both would argue that. HDZero latency is about as close as you can get to the analog experience (on paper at least - I've never used HDZero personally). Every little bit of latency reduction helps and adds up - whether that be latency in the video system, RC link, etc. Optimization of latency absolutely can and will affect reaction time. As you pointed out, there are tradeoffs and different people prefer different setups for different reasons. I think it's great to have options. PS : My original comment was about the cool visualization of latency.
Head tracking is one of the coolest things you can do in FPV fixed wing. Great demo and setup video, with the HDZero goggles + ELRS it is so easy too. I love that little reflex HUD too, really awesome.
Couldn't agree more! There's so many guys flying fixed-wing at clubs that could have an incredible experience flying fpv with head tracking. I hope we see more
Ryan, Thank you so much for these head-tracking videos! Your videos are inspiring me to set up a head-tracking fixed wing plane. This video was exactly what I need as I'll be using BetaFlight. Dave Messina
As someone new to FPV and looking at whoops your example of the latency helps me in deciding a goggle option and spending the money on HDZero. I'm still going to start with a box analog set and computer sims for now though but at least I know the upgrade path I want to go after I'm comfortable flying and want to stick with the hobby.
Thanks for your video, I’ve had the hardware setup on a Marlin for a while and couldn’t figure out the channel mapping. Great video, looking forward to the hard wear set vid.
Hell yeah awesome job! Its funny I recently put out a video on how to FPV head tracking as well XD, excellent video man! (also motionsic gimbal *chefs kiss*)
I run 03 on all my scale fpv jets, Im actually about to finish the new 70mm f22 with fpv head tracking in it as I type this! (jealous of yer 90 tho) hell yeah!
I am absolutely thrilled with your video. Question: which OSB did you use and how did you project the telemetry data into the OSD? Where does the OSD get the speed from?
I'm glad you liked it. I am using a INAV flight controller that sends OSD text to my goggles to overlay on top of my FPV video in real time. Speed and altitude comes from a 10hz GPS, but for best results an air speed sensor can be installed (pitot tube)
Very nice setup! The holo sight is a very nice addition. Too bad the wireless setup is not more reliable, the less wires you have flopping around the better.
Great stuff brother. Btw I needed help with headphone use on Hdzero goggles with the live drone on board microphone. Would you be able to redo the tutorial? With updates? Thanks 7:11
@@RyanQuellet yes so. For starters, I simply hooked up my headphones thru 3.5mm (headphone-in, next HDMI-out). I’m using foxeer extreme with built in microphone. But I don’t get any audio. Is there a setting I need to enable?
@SbangFPV for analog audio to work, you first have to switch to expansion bay at least once to initialize analog audio / video. Expansion bay power must be enabled too. Then go back to hdzero source once you have analog audio working
Note that the files need to be placed in a folder called ELRS which is in the root of the SD card. If you put the files in the root, the flash will not find them and we fail. See the first sentence of the instructions that you linked.
Nice video. Some criticism to the tape measurement though: iirc the 3ms latency is only achieved with the nano 90 camera (540p90 mode). However, the setup states it uses the micro v3, which only has the 60hz and 30hz modes. So the calculations and measurements and what you actually do are somewhat off. Also, the 3ms are only first pixel latency. I'm not entirely sure if the 30ms on DJI are also first pixel (never flown DJI). But if it's full frame, I'd call the comparison ... lacking.
3ms is the latency of micro v3. Nano 90 is actually as low as 2.5ms. All latency measurements for all video systems are first pixel change, not whole frame. Since video is continuously updating from rolling shutter cameras, this is the proper measurement
It's the reason i want HDZero Perfomance, and its build-in gyro( or accelerometer ) inside the goggle. To run RC like this. Hope HDZero also available in my country, sofar it price problem. If hdzero also build Very lowend goggle but with headtracking and low latency solution, how it would be looks like ? Will it also keep quad antennas ? We need digital penetraration of hobby fan, to suppress price to play with. want this. Want this. Want this HDZero goggle.
nice video, i also want to build HDzero in my Avios Super Tucano soon. why did you leave out the cockpit glass, because of the view or because of the cooling of the VTX?
You can always use the 3.5mm trainer cable. If you want wireless, then the ELRS TX must have backpack functionality. Most newer radios that have ELRS inside have Backpack
Most open sourced projects tend to be finicky with only the most tech savvy to figure it out. Never are they “follow these simple steps to get a hassle fee experience”. You may have to fiddle with it relentlessly
@RECK_Adventures darn. Try it again and see if it works. To test if backpack works at all, I set dvr recording to manual, then in backpack LUA, I set recording to my arm switch. Then I tested if recording started and stopped on a switch. If that doesn't work, then backpack isn't working. Also try using 333hz mode with 16/2 ch mode

I don't know if you noticed, but this dvr video is hdzero. It looks nothing like analog and you'd be hard pressed to find people that say this dvr footage is analog. Lots of us do fast 100mph passes 2-3ft off of the runway (it's fun). Please do not attempt a maneuver like this with 4.5ft of delay on a system like O3 - it is dangerous to people that might be picking up a plane on the runway and a last second correction is needed. 4.5ft is a fact, it doesn't change based on our experience (sorry)
I would NEVER fly fast at 2-3 ft above a runway near pilots as that’s just irresponsible. All fast flying is done well away from any people or runway so not concerned. If you are worried about making a 4.5’ correction at 120mph then you are already behind the reaction curve. I did really enjoy your video though and your setup is pretty awesome.
Safety is important for sure. I've had a near miss before, so it's on my mind. Still, we all fly our jets fast and low to the runway - especially line of sight guys. This is no different (mostly)

Yup would like to see sport jet on inav with red dot and head tracking. And reverse thrust 😊
Comparison of latency with ruler was epic.
At 120 mph a foot or 2 of difference you won’t feel nor see. This is a salesmen tactic to sell an inferior product compared to DJI
@@APS-yo8oy I feel dji latency. Very much. And also his minecraft graphics. Not even close to HD.
