Everything I got wrong and left out of my DJI O3 Air Unit review

[@AfterFPV]

The healthy dose between honesty and accountability is so hard to judge. Don't ever beat yourself up you're appreciated.

[@hertje21]

i would really appreciate a 20 minute video off fardwell beating himself up. 2 minutes would also be very wel recieved.

[@namr2000]

Bardwell does a better job with journalistic integrity than almost any KZbinr and certainly most big outlets. This is why you're one of the most beloved creators in this hobby!

[@ArtusMucFPV]

He makes a lot of efforts to sell and makes money - and we all know it. He is an influencer of the mainstream “DJI”.

[@erikflies]

And he also has a great sense of humor 😁

[@Jubijub]

It's actually so refreshing to see someone admitting when they are wrong, and factually correcting things and moving on. I think every hobby needs a Joshua Bardwell, and FPV community is lucky to have you. As a noob to this hobby, your content is absolutely essential to avoid tons of mistakes. /me is off building your 5" drone :)

[@CarbonGlassMan]

How cool is it to know that you're one of the world's most helpful people for those in the FPV hobby?

[@daryoushborja5115]

You are the best gift to FPV

[@McTurha]

In winter if the goggles are too cold, they fog also from the heat of your face. I use hand warmer to warm the lenses if they are too cold and are getting foggy.

[@JoshuaBardwell]

Good tip.

[@MCsCreations]

Thanks for the updates, Joshua! 😊 Stay safe there with your family! 🖖😊

[@ror-ys3qp]

Another important point missed. O3 system needs an armed signal to output full power. Same for upgraded vista type AU as well. This makes O3 system useless for wings without a FC.

[@MactacFPV]

FYI I believe that that the newest beta firmware (the one that gives you backwards compatibility with vista) for the goggles (and therefore likely the air unit) might disable the ability to use the hacks, so we might lose that as the firmware updates roll out.

[@creationlabsinc.189]

Purely speculative

[@WanneSomeSoup]

Don't worry, there will be new hacks

[@aviatoFPV]

@@creationlabsinc.189 Check out mads tech, he shows that the hack doesn't increase the power as it did on earlier firmwares. I'm pretty bummed.

[@andytroy]

@@aviatoFPV Check his comment underneath the video, he says he got it working again

[@onepiston5956]

“If” DJI somehow enabled remote ID in their products, they would have to make it so they user could enable/disable it. This is because many people are using their products (goggles/air unit) in sub 250g drones for recreational purposes where RID is NOT required by the FAA.

[@geeH2oS]

I think what you said about the v2 goggles not having a fan is incorrect.

[@WillFly4Food]

I was thinking the same thing. I have a pair of V1's and V2's and both have a fan. It's hard to believe the Goggles 2 were designed without a fan.

[@dupfpv14]

The new goggle 2 have no fan.. v1 and v2 have a fan 👍

[@leroycarter7183]

This is understood. Just goes to show that we're all learning about this new product together and while we might encounter some concerns, it's great to discover solutions and get best results later on

[@squintsfpv]

A quick and dirty way to share the video via HDMI is screen sharing via a Chromecast dongle. You can also use an Android TV box for an HDMI out. Runs all the apps needed, including analog apps like FPV viewer. You can also plug up an OTG analog receiver right to the box.

[@JoshuaBardwell]

This may work for casual viewing, but for those looking for a high quality feed, including professionals using DJI FPV on set, it's not usable.

[@squintsfpv]

@@JoshuaBardwell Oh, I totally agree and that's why I prefaced quick and dirty. Lol

[@squintsfpv]

@@JoshuaBardwell I'm also curious if you were to use a USBC dongle that has HDMI out but also a USBC 5gbps input instead of sending the signal USB c to usba to USBC like you did in your video

[@JoshuaBardwell]

The problem with the adapter is that the USB host device switches when the DJI fly app is used. It's not about the speed.

[@gandaulf_fpv6925]

You will always be the man. That will never change.

[@WR3ND]

Thanks. I'm the sort of guy that likes to deep dive into specs, so this is great.

[@MrTimmyGT]

One thing that you didn't get wrong but didn't mention is if you are new to HD and have bought into the new system with Goggles 2, unless you bought the goggles from DJI directly you will be stuck staring at your 03 air units sitting on your bench until mid January because DJI decided to withhold their retail partners stock until then. Guess they are hurting for money and really needed to get those initial sales....🤦‍♂️

[@fpvgiggles]

Order from DJI, they ship super fast.

[@Philomathe]

[@rotardx]

Building my first drone, didn't know anything abt drones a week ago but now I'm building my own, couldn't have done it without Bardwell.

[@ror-ys3qp]

NOTE: using V2 when you switch back to Vista type air units you can not use audience mode until you bind with a Vista.

[@j005u]

The reason HDMI dongles don't work with DJI Fly is because the goggles and phone have to reverse the USB host and gadget roles due to the Android Accessory Protocol. Fly should work if you plug the dongle into the Goggles side, but obviously HDMI won't do anything like that.

[@woodfpv2764]

Bardwell da goat

[@simp502]

Thank you for the clarification. Good to know more about the O3.

[@hornyj1]

On the being wrong theme… I wouldn’t be so quick with stating O3 would run on 25mW in non-FCC regions. It has automatic channel switching logic built in, so it should be eligible for 100mW max RF output in most European countries now! (not sure what regulations are in other non-FCC regions). Not saying 100mw is all you need for everything, but some people could actually live with that much better than with 25mW. Especially if you add the more efficient codec O3 is using (H.265) that provides reasonable image quality even down to 3Mbps…

[@ronniequalls7217]

Yall finally got me , just ordered the DJI Goggles 2 😂

[@drewdyess9241]

Very helpful in-depth info, the O3 is very interesting indeed! Been a while since I was serious about my fpv setup but this one's making me so curious.

[@MaxRovensky]

[@steadiged]

Ohh yeah 😃😃 My o3 is arriving tomorrow... And I am happy that I have DJI RC PRO remote to have clean feed from V2 thru HDMI ))

[@gregorydahl]

21:30 The 4:3 footage got mislabeled as 4K60 here. But it is marked 2.7K60 on the phone card, and you do point out afterwards 4:3 can't do 4K.

Good catch.

[@runpuppyfpv5744]

Do you think this new system will be your new daily driver?

[@Guenounovitch]

Enjoying remote id apparently

[@luemas3219]

Very helpful and appreciative of all the work you do. Some thoughts on hacking the unit to obtain additional channels and cautionary tale. The frequencies these units operate at is within the wireless networking range and has been limited to what appears to be non-overlapping or least interfering frequencies. Either you could be causing your neighbors to become very annoyed with you, or perhaps negatively affect your own wifi without even realizing it IMO

[@tomaszboril]

Hey Joshua, please include the link for the USB-dongle you are using on Android devices for HDMI out with affiliate link. I am not the only one who would go for it after watching this video I believe. Cheers!

[@sarunoatama]

The in-goggle view shown seems to match the wide FOV not the normal. Is this what you meant?

[@quadthingcopter5984]

After testing the 03 today, i was pleased with the goggles dvr view and also the penetration of the video signal, it was not going blocky in the trees where my vistas usually do, the image in the goggles had no jitters but the footage from the 03 air unit had jitters when using rocksteady, i read that this can because the esc's are at a similar frequency, i have 16bit esc on my aircraft so it is not possible to change this as they are not 32bit, well i think this may defeat the object less stabilized video with stabilization on! also the 03 seemed to stop my gps from finding satellites where i had no problem of getting a link with my previous vista, this maybe down to the gps module mounted above the camera and maybe The 03 camera is giving out noise where as the old camera did not affect it. I may upload a comparison video of the dvr and the 2.7k 60fps recording with the inbuilt 20gb storage so not an sd card issue. I hope these issues can be rectified, don't want to think i have wasted money and time.

[@jdrone]

I'm glad I got the information I was curious about. The part about nuclear and the part about the output of Jimmy Lee will be the biggest issue. I watched the video well.

[@agtjackbauer]

No fan is a deal breaker for me. Kinda sucks was going to get them.

[@sakuratears9731]

There is latency information in that srt file. Below the timestamp, there is a “DiffTime” and that is the latency. Actually the timestamp itself shows the latency, you just ise the second timestamp and minus the first one.

[@bestbattle]

Are you sure? How is the air unit supposed to know the latency at the receiving end?

[@bestbattle]

If you look at them, 33-33-34ms, it just tell you the delta T between log entries

[@JoshuaBardwell]

It seems like only the goggles can truly know the final latency since only they know when a packet was finally received. But in the other hand, only the vTX knows when a packet was sent, and it's not like they sync their clocks or something. It's a bit of a mystery.

[@tomsop]

I am waiting for the OS 4 which is supposed to be cross compatible with HDZero.

[@seb-depp]

Love it that you corrected mistakes and added info. Seems that the new beta killed the hack again. Won't buy it if it can't be hacked... Just had a thought: If you update or active the Air Unit using a VPN "being" in the US shouldn't the Air Unit think to be there and switch to FCC?

[@aviatoFPV]

Nope, the DJI app checks your carrier and stuff, you can't activate without sim card.

[@seb-depp]

@@aviatoFPV Dang!

[@JoshuaBardwell]

That makes no sense since activation is done on pc and doesn't require you to plug in your phone. Right?

[@ollie_fpv]

[@GAMINOES]

O3 died just after 3rd short flight. Light (GREEN/RED) turns on and quickly turns off. It was working fine (activate/update/bind/link).O3/Goggles V2/RC2 link went off and LED light on O3 unit turned off. Now when powered on via FC (GEPRC F722 40A AIO, 6S battery) - LED on O3 comes on for a split of a sec, goes off and then nothing. My drone got crashed because O3 got off while in the mid of the flight, i lost goggles video feed. Then if i remove the battery and plug it back in the green light comes and goes in a second. Connecting O3 directly to the computer via USB cable (same computer, same USB port/cable that used to work before): 1. O3 LED turns GREEN for 2 - 3 sec 2. While the LED is on, Windows Device Manager shows "Unknown device" 3. O3 LED turns off 4. Unknown device disappears from device manager 5. DJI Assistant 2 does not see O3 anymore 6. O3 internal storage does not show up in Windows file explorer 7. O3 get a little bit warm (not hot) if I keep it connected to USB cable This exact same problem someone else had and posted on DJI forum. and now i m having the same issue. Who else do have? any fixes?

[@singlesidedfangz]

I think you said the screws were M2 on the air unit. I believe they are M1.6 used to replace with longer screws to screw the air unit to frame.

[@ndcapper]

There seems to be a bunch of small features that they should implement i.e clean video output option. I guess feedback is just provided via a support ticket.

[@socksincrocks4421]

Hi Josh, is the O3 exclusive with DJI's goggles? I'm new to the game and want to put together a high quality FPV camera that can function also for action filming. 1. Can you use a third party video receiver with the O3? like a Moneagle monitor? 2. Are there any video systems that are encrypted / secured end to end? I don't like the idea of anyone tuning in to my vtx and spying on me. Thank you

[@JoshuaBardwell]

You can only use the DJI Goggles 2 and DJI FPV Goggles V2 with the O3. Nothing else. The O3 air unit is not encrypted as far as I know (maybe it is I'm not sure) but the O3 system doesn't have "audience mode" where anybody can tune in. You have to manually enable the option to broadcast your signal to viewers.

Similar to Mini 2's camera, but better, and can fit in a 4" quad LR cruiser.

That's correct, I just checked, goggles always show wide FOV. Thanks!

[@JohnCuppi]

I get a feeling they are not going to fix the lost bind bug - because, if they port the vista and air unit connection to the V2 goggle firmware, they likely ration that you should not need to boot into the older DIY side OS anymore. 🤷‍♂️

Hi, my airunit O3 is very hot, I can't figure out how powerful it works. I have the FCC hack installed. The power meter showed ~4w in lower state mode and ~12w without it. Can I see the transmission performance in some software? I didn't observe dynamic power changes. The power consumption doesn't differ when in close proximity, even when the signal has almost disappeared.

[@PIDtoolbox]

Great video, thanks for this. One question, at time 20:20 the explanation of the FOV does not line up with what you are showing. maybe I am mistaken, but I'd be grateful for some clarification here. What I am noticing is the FOV changes when you arm if using > 60fps. For example, if I am in 4:3, 2.7k, 120fps, when I arm, the image FOV goes down (zooms in). If I select 100fps it zooms less, and at 60fps there is no zoom, the image looks same as when not armed. The same is true if using 1080, 120fps crops most, 100fps less, then 60fps does not crop at all. Again, this only happens at the moment you arm. after you disarm, 10sec later of so and it goes back to wider FOV. Has anyone else noted this. I am running o3 firmware 01/02.00.00 (latest as of MAR 10. 2023) , on V2 googles (firmware 01.06.00.00).
