Very good work Ian, you're going above and beyond to help generate knowledge for this awesome community!

[@lifebehindtheselens]

I appreciate people like you who have the balls to open up equipment like this it scares the shit out of me let alone don't have the money to even fuck something up like this

[@FAQUERETERMAX]

The technology DJI has packed here is amazing! It seems like magic to me. They're dealing with extra low latency and very high definition, while also keeping it extremely light.

[@speeddemon467]

Just imagine where the technology will be in 5 years (10 years?)! It's a good time to be alive (and a geek ;)

[@meotyda]

To be honest i wonder, now we have a 4k streaming between router and wifi router, why is it so hard to make a 4k air unit

[@FAQUERETERMAX]

@wave4308 basically two things: distance and latency. It's pretty easy when devices are close enough and not moving, with few obstacles in between, but as things get further, signals get weaker. Also, 4k streaming doesn't need to deal with latency, so you can buffer the video to account for lost data packets. Doesn't mean it's not possible, I mean these kind of systems seemed impossible a few years ago

[@peterkleborg3048]

These types of videos are just so wonderful! Thank you!

[@Falcon1fpv]

Very much appreciate your efforts and detail in this tear down, WOW, couldn't take my eyes off the screen, Thank you!

[@vk2icj]

Gee Whiz I learned today that I’m never opening a Dji goggle. Thank you Ian for making this video. It was fascinating!

[@baggszilla]

Jesus criminy Christ the complexity of these goggles is amazing! Thanks for this Ian! Cheers!

[@frankeversley5541]

Awesome video Ian! I learned a lot about workings of these new goggles.

[@anlpereira]

This is absolute insane. Great Deep Dive. Thank you very much. 200mW (23dBm) is a great update in output power.

[@KmonCentz]

Fascinating teardown... nice job brotha

[@pabloabbate6970]

Great video, thanks for sharing these precious info with us. 😉

[@user-ks5jh1rp6d]

I enjoyed watching and sharing this great video. Thank you.

[@T-kind]

Thanks Mads (Ian), great teardown and explanation!

[@MadRC]

Thanks.

[@FPV-Drones]

Great video master!

[@jakekisiel7399]

Wow! He’s not scared to take it apart at all.😮

[@honeybeedrones5510]

Great work thanks for what you do

[@MadRC]

Thanks.

[@fpvkevlar8101]

Great tear down.

[@NunoFPV]

Great video ! Thanks 😉

[@erlandfpv]

The digital potensio meter have help me a lot, to do and rember my focus point, you know what, googles 3 have a more precision focus that i experience, i have struggle a lot when adjusting focus on my google 2, but veey thank tp dji to add a digital number when i adjust my focus number,

[@LehtusBphree2flyFPV]

DJI knows you do teardowns and they sent you the extra glued GOGGLES just to fuk with you

[@richardamiss7000]

Same thought...haha. Alrhough, actually DJI aren't bigs fans of Ian, and he buys them himself with Patreon funds. Would be funny if DJI figured out which pair he bought and added glue though 😂

[@LehtusBphree2flyFPV]

@@richardamiss7000 🤣🤣🤣🤣💯 EXACTLY

[@loabrasumente2283]

The Chinese on the ZV902 labels says 额头天线, which means "antenna on the forehead". which says nothing about what it is. lol

[@MadRC]

Haha brilliant

[@redreefbud]

Wow man 🤯 very intricate. So much stuff packed in there 🤯 i have integras but don't like them. I can't seem to get correct focus. Tried all the inserts. 1 of my eyes is different than other 🤯 still can't get totally clear and full picture. Maybe if i make screen smaller. 🤔 Think I'm already at 90% I'll have to try 80 😉 great video man 😁 very interesting

[@Raptor50aus]

By the way after reading the manual these goggles are also fantastic for watching movies in 2D and SBS 3D. Audio via USB-C dongle.

[@Jimbo-in-Thailand]

👍👍Mads Tech - Great teardown video! You're definitely a fearless man! I'm glad Goggles 3 includes diopter adjustments a la Goggles 2. I'm curious why DJI opted not to include it with Integra. I tried on both Googles 2 and Integra at the mall when I bought my CE M4P last November. I loved the clarity and the convenience of individual diopter adjustments, vs Integra's less accurate lens kit trial-and-error approach. I'm wondering, range-wise, what improvement O4 Goggles 3 brings vs O3 Goggles 2 in CE member nations. In fact, I don't even know if I'm getting full O4 capability (2.52Ghz band) here in CE Thailand. Do you think the extra cost of Goggles 3 in CE mode is justified vs finding a deal on the older Goggles 2? Thanks!

[@quadmods]

Very cool to see! Isopropyl alcohol releases that hot snot glue very easily. Cheers 👍

[@tattoosatan]

thanks for the video, and now, is the foam the same from the goggles 2?

[@Sir_Hubris]

You live up to your name ... this is really "Mad(men)'s Tech" ¶ ; - )

[@CarbonGlassMan]

I still have the V2 goggles but I took most of of last year off from flying. Probably only flew 30 or 40 packs last year. Ready to get back to it and thought about getting rhe goggles 2, but maybe I should consider the goggles 3? I like the external cameras like my skyzone 03o goggles have.

[@Spyder2010ify]

Super Video.

[@rubengarciajr7560]

Great vid there Ian. Was wondering though, if the remote controller doesn't transmit to the drone (only goggles to drone), why do they have the HD and RC strenght on 2 meters on the telemetry.

[@danielson101]

nice!

[@71wiked]

@madstech ... wondering if you can unscrew the lens to swap them out for some lens that have a better FOV. They look like they can be some M8 lens 🤔🤔

[@Ice-FaceMedia]

Yes sir , definately appricate the full tear-down....the world can now go-ahead and tear them down....lol🏋‍♂

[@BerjalanDiatasAwan]

Can you make a video to replace the battery?

[@vernelfpv]

tried the foam of the 3 into the goggles 2, it did not fit

[@RichardBerish]

I'm working on taking the front two camera IR filters out so then in 3D mode it will have also night vision.

[@shuflie]

Electronic measurement of dioptre adjustment probably gets sent back to DJI to let them know settings most people use. Could be sent back to them and they can then use this data to help reduce cost in future versions. Als DJI webpage for the Goggles 3 list only 2 transmit antennas and 4 receive.

[@MadRC]

DJI spying on your eyes.

[@MadRC]

On the antennas only 2 can transmit at once. And 4 can receive at once but thst can be a mix of the 6.

[@peterklemenc6194]

Was considering a purchase between the 2nd gen and this 3rd gen Goggles. But the Goggles 2 have 51deegrees FOV versus the 44degree on the Goggles3. Aren't the 2nd gen, in this regard, better for FPV flying? (this is considered with the pairing w/ O3 and eventually O4 units.)

[@DianKuChannel]

What type of glue is in the antenna connection?

[@orlandojam8]

a good mod is changing the pip cam with wider fov lens and make the hinge go up to 90degrees 😂

[@CraigLevine]

How do you remove the goggles 3 antennas to replace them with ORT Helicals?

[@JPspinFPV]

A certain KZbin personality adamantly disagrees with me, but I think its entirely possible that dji could include gps and RID on future air units. Considering the hardware exists in the new goggles and how ubiquitous DJI systems are on bind n fly models, it could mean an easy method of compliance with Standard RID for manufacturers going forward. I'm looking at you, iFlight.

[@silesiabiker541]

May I ask - in Goggles 2 are there two tx/rx antennas or is it more mixed? So changing only the foldable antennas to something better is enough or would it be wise to do something with the internal patches too?

[@ChrisHarmon1]

Hi Ian, the optics look larger then my Integra's. Do you know the diameter of the lens? Is the entire area of the lens viewable or is it partially blocked like the Goggles X lenses? it's a little hard to tell from the videos, but the lenses look 100% clear. I'm hoping these have a slightly better viewable area(see corners well) over the Inegra's. I managed to put a Walksnail V1 goggle pad on my Integra's, with the nose area cut out of the foam, and this got my eye close enough to just barely make out all four corners. If DJI would release a 10 gram 1s capable VTX/camera I would 100% switch to DJI. The lightest I can get my vista and cam is 12.xx grams.

[@axm2689]

Do these goggles do rID with o3 air units somehow?

[@petermorrill9410]

I want to remove the speaker, but didn’t hear you point it out. See any issues if I try this?

[@Quad_Father]

Hi Mads Tech - can you please help explain the battery in the AVATA 2. It’s a 4s lipo (I think) that is over 2000 mah capacity but only weight 146 grams. How is it so light and such a high capacity for a 4s? And gives such long flight times. Have you torn the battery down yet?

[@jakekisiel7399]

Send it back to DJI under warranty?

[@typxxilps]

SIYI A8 mini 4K - any updates of that product cause there had been updates announced for fixed wing mode especially for inav ? I had searched for the video cause in that live stream a year ago you had mentioned a full review I could not find at least today. I always found them interesting solution cause here the drone flying is becoming impossible cause everyone can call the police and the usual action of the police is a confiscation to investigate things further which I do not like at all. I need to move ahead and fixed wing is the solution sooner or later. I can only fly fpv from the inside of a motorhome otherwise people will come over start discussions, debates, acusation or ask kindly questions about flying and the footage or how it looks and feeels.

[@vk2icj]

I would be interested in seeing if the controller connection to the goggles introduces any latency compared to the goggles 2 and controller 2. When I fly longer range I prefer to lose my video signal prior to my control link. This way I have the opportunity to try and get some altitude and regain video connection. I imagine that you will lose both video and controller connectivity at the same time with this new goggle system.

[@gurmiro]

you're right. however, the signal connection is quickly restored while doing RTH.

[@danielson101]

that screw?

[@BlueDroneBlues]

I was hoping you’d figure out if maybe one of the cameras that weren’t working might have been spliced by mistake during assembly?

[@MadRC]

One cam only works in 2d mode. In 3D you get both cams.

[@robertlow9287]

If the goggles were left in the Sun could you replace the displays?

[@Mde7FPV]

OMG this video makes me very uncomfortable 😂. Thanks for that interesting in- sight. Seems to be a lot going on under the hood.

[@planktonspongebob7746]

the battery side ?

[@supermortal]

Could it be possible that the forehead antennas are made for the remote control (and RC3) ? (not for the VTX?) My guess is according to the dead zone test ,there is no significant difference between G2 and G3

[@MadRC]

No they are SDR. The rc antenna is in the front bottom corner

[@janfalke2350]

Anyone knows if goggle 3 Antennas are suitable for Long Range ? Or rather Stick with V2 and Patchys ?

[@captain.sandro]

Is there any technical possibility that the googles could tranfer any data to DJI passiv, so not intended by the user while it is used and disconected from any peripherie?

[@canadiangemstones7636]

Yes. The CCP is watching every move you make and every breath you take. Also every cake you bake and every smile you fake.

[@sptrader6316]

I am concerned about the cable connection to the battery. Constant flexing of the cable being on the head strap could cause breakage. I Much preferred the Goggles2 battery setup.

[@MadRC]

TBH this wont be an issue, its a robust cable in the strap.

[@ricyjo]

so the optics are exactly the same then?...

[@hamlonhamlonsson505]

Ian, what will happen if you disconnect the GPS? Will the goggles continue to function and just show a message abut the GPS or stop working alltogether?

[@treloar_photography7401]

Love to know if you found an answer to this

[@jakekisiel7399]

It’s easy to pull apart, but can he put it back together?

[@jakekisiel7399]

Just play the video in reverse?

[@Mupshot]

a shill for opening up electronics

[@hi_desert_rat]

Open shill you might say.

[@idiotsnifff]

Lol

[@quadthingcopter5984]

Cannot find any info they are compatible with the 03 air units?

[@MadRC]

Not at this time.

[@Alex-ms1yd]

does it still work if gps antenna is disconnected due to some unfortunate failure?

[@MadRC]

Technically yes however DJI may block take off. I don’t know in FCC

[@rjbishop12]

I doubt the Avata will launch as it would be aware of a GPS failure in the goggles.

[@Alex-ms1yd]

I see, guess we wait for airunit behaviour before goggles purchase decisions 👍

[@sr-prod]

what about some aluminum foil over the gps antenna, would it make it think it’s indoors or something?

[@WildpixFPV]

Is there any way you can measure the transmit power that these two antennas at the top put towards our foreheads? I'm worried about frying my brain during a flight day.

[@gurmiro]

most of goggles antenna design is focused on maximizing reception capability. perhaps the tx power is very low..

[@WildpixFPV]

@@gurmiro I hope it is. 🙂

[@haka8702]

Quite crazy if you look how outdated the optics are. Oculus from 2016 had significantly superior optics and since then we've had 5 optical generations, all significantly improving on headsets..

[@fezfpv]

That liltle fan need to upgrade

[@travislindgren7158]

It's all about the DJI OcuSync 4.0 Drones. O4 Sync Transmitter is a game changer! Cheers 🥂 🍻

[@jaybomb5022]

Any idea why my screens may intermittently work on my Goggles 3? I see a flicker when they power up but there is a 30% chance that they stay on.

[@MadRC]

TBH this sounds like either your proximity sensor is not working or they are faulty.

[@jaybomb5022]

@MadRC Thanks! Good thing Amazon has a good returns policy lol. I ordered a new pair to swap out.

[@Wizzzzz81]

In the googles 3 exist GPS antenna, for what it is?

[@gurmiro]

auto RTH.

[@Fermen80]

Are the external antennas removable?

[@MadRC]

No

[@25milliwatts]

dji glued UK first batch only 😅

[@janzajicek9246]

There is (almost) no chance change atnennas to circular😢

[@PatrioticQuadriplegic]

Tear down the motion controller to learn about its head tracking sensors

[@MadRC]

It’s glued together sadly n

[@Arri.]

The issue i have with the goggle 3 is fov 😢

[@FAQUERETERMAX]

Too much or too little?

[@gavinzheng1486]

4:46 That Chinese says:"forehead antenna L and forehead antenna R"

[@jakesdronelife6307]

Junk ill keep on rocking my goggles 2 I just don’t like the fact there’s no straps not like they work with anything I have anyway can’t use them with my 03 units or my avata 1 but when if they do a update I’ll get the avata 2 if they be on backwards compatible with my controller 2 and goggles 2

[@jakekisiel7399]

Fat shark is watching this video, closely. 😂

[@maxsteal1982]

Hay how about make a video to target. Why do we need so many controllers? DJI IS NOT being environmentally friendly. You KZbinrs must reach out to DJI to also have the controller 3 compatible with others drones like the Mini 4 and Air 3 Or the RC 2 compatible with the Avata 2. This seems so logical why hasn't DJI done this? It's all O4 so it should just be a software update.

[@MadRC]

Money.

[@lilgbz28]

F..k remote ID. Fly safe my friends
