You answered all the questions I could have asked, thank you. You probably also saved some people time by not having to try different cable configurations. Thank you!
You covered pretty much everything in a nice and concise one Ian, thank you! Here’s one for you, what about the OG mipi cable from the original DJI camera/Polar/etc? That connector is the same and it’s wired differently than the walksnail one.
Is the FCC hack really moving the goggles over to the US mode or is it more a “power/channel unlock”? In Europe, I heard that the 5.2Ghz band is available/used. Is this still the case after the file is placed ?
What does the wiring look like on an RC car? Can I connect plus minus from the air unit directly to the battery cables that lead to the ESC? or is it better to take a second battery?
people told you about the quality of the image yes it is very good in recording, put on the o4 lite in direct vision while piloting it does not go at all with the N3 mask and this fov of 117.6° of the camera of the o4 lite, those who want to pilot not make images of videos past your path, if you piloted on vista before you will be very disappointed.
Thanks for your awesome information as always, Ian. Regarding longer cables for the 04 camera - I have the Chimera 7 04 conversion kit coming from iFlight, and they told me a longer cable is included in their upgrade kit for the Chimera 7. Perhaps iFlight already have stock of longer cables. 🤷♂
Please, please can you visit the OSD issue, I nav and betaflight fonts and the OSD work around. Sure many people are confused like me jumping from O3 where the OSD does work albeit with?. Thanks for the great content.
Great review as always ! Do you know what mipi will fit the o4 lite , I want to use it on my 5” quad and it’s too short with the kit. Will vista mipi fit
Quick (maybe dumb) question... I have the Googles N3 and the motion controller 3 (that I use with my Neo). I'm planning to buy a BetaFPV Pavo 20 Pro drone with an O4 air unit. Will I be able to use the motion controller 3? Or will I be forced to buy the FPV Controller 3 to do that? 😀
Having trouble recording the goggle view flight stats at the end of a flight AND onboard recording at the same time. In order to record the flight stats, it seems I have to disable "auto record on takeoff" because it stops recording at the end of the flight as soon as you disarm. But the flight stats don't show up until after you disarm. So, you can get it to record the flight stats by disabling "auto record on takeoff" and then just manually hitting record before a flight. BUT, it doesn't seem to record onboard video also. Even though I have record "both" enabled. I suspect it may have something to do with being in low power mode while waiting to take off. If I turn off low power mode, that might work (haven't tested it yet) but it may overheat while waiting to takeoff. So, is there an easy way to do this? Or is this another one of those DJI "features"?
Hey Mad, thank you for all the hard work. What I wanted to know as a walksnail user. Why is dji not able to differentiate fps between what is recorded what is given out as the live feed? Isn`t walksnail doing this already? Flying at 720/100fps but it can also record at 1080/60fps on board recording? Am I missing something?
@MadRC I'm running 04lite on G2 am i right in thinking that at this moment only 1080 -100 and 4k - 60 work correctly with the G2. I have tried the other 4K option but i'm getting frame lag. Think you have mentioned this before Ian, Ive just forgotten. Thanks for all your work man. Cheers Pooka.
great video. I would like to use the O4 pro for a particular project. Do you think it is possible to somehow receive the signal on a monitor (ex hdmi) or is it only (and will always be) compatible only with googles?
Great video like always! I finally upgraded from the dji Caddx vista lol but with the 04 pro unit i dont seem to get low battery warning from my lipos in my goggles N3 ? I can see the voltage etc but no warnings is this something 0mitted on this ver? My osd setting's and battery info thru betaflight all look good
The cutoff voltage is crazy strange. Some people say it goes down to 3v without a BEC, you and other testers show it cutting out at 3.6v. Why this massive variance?
Maybe it's dependent on component tolerances (i.e. some air units will go down lower than others) as well as configured power levels, wire gauges, measurement accuracies... quite a few variables in the mix here...
@pfeerick id like to think that dji had better component supply and QA to prevent that. Seems like something you'd expect walksnail to do but this is quite reliable at 3.1v cut out. I guess it's to do with the options/vtx output/framerate etc...
@@Tokyo_Dom that would certainly mitigate some of it, but even so, you have 10% standard component tolerances, and aren't these being run below spec'd voltages? So rather than binning (categorising) like with CPUs, DJI just state a higher minimum voltage.
how is the range and penetration effected in race mode, not something I've experimented with would love to know. could we in theory still fly long range but in the low latency race mode
If i use racemod 25mw, how much mw does the goggles produce? from the video can it be twice as the O4 Air Unit? (im not a good reader of spectrum analyzer LOL) on a race that could still kill other pilots if they sit next to you, or mess with the timing system for that band.
Amazing Info, really appreciate it. got a question about antennas(O4) they seem a little to small. maybe putting 1 antenna (FlyFishRC Dual-Band 5.8Ghz/2.4Ghz UFL Antenna For DJI O3 (145mm)) Will get better range/penetration? what do you think about it? i mean, getting longer antennas on o4? Thank you
@@Cornusse Same. Even though the G2 is not a worse set of goggles than the G3 and has its reasons to compete with it for different people and use cases, I doubt dji will invest in “old gen” in any way going forward.
(edit). I commented before completing the video. Apparently not. That's fine, I'm happy with the 03 air unit. Maybe next year when they make the 04 obsolete.
Remember, a lot of us are also well invested in V2 tech. But!, the N3 goggles are only $229 and the 04 lite is only $109, so for about HALF of what the V2's originally cost, we can have the N3 goggles and the 04 lite VTX with camera! Equip a quad with 04 for a mere $339 - get 20ms latency - Pretty awesome! :)
@@KOrnhOliO1 the range on the light absolutely sucks and so does the camera angle there’s no possible way that you would buy it for $110 and like it. So yeah you’re gonna go with the $220 version.
I've encountered a red flag "connect to dji fly outdoor" message that limits the mbps on g2/04 combo, has anyone else experienced this? I'm waiting on dji to look through my log files to isolate the problem. I had to go to manual channel selection and select 40hz to fix the mbps problem, but still have the flag. I''ve updated goggles twice and cleared memory, air unit twice, consumer drone series, and connected to the app.
I had the lite o4 yesterday flying home on 2s went down to 3v per cell Bit low as I was exited how does this new unit perform 😅🙌🏼 Thx Ian for all your wark and support
Can someone tell me if these are accurate? Integra + DJI RC Motion 2 works with: O3(Mini 3 Pro/O3 Air Unit), O3+(Avata/Mavic3/Classic/Cine/ProCine), O4(Mini 4 Pro/Air 3/Avata 2/O4 Air Unit) Goggles3 + Motion 3 only works with: O3(Air Unit), O4(Avata2/NEO/O4 Air Unit) The Integra works with O3, O3+ and O4. The NEO is the only updated drone that does not work with the integra + Motion2 combo. And, by all indications, this can be fix in software. THEN WHY buy the Goggles3+Motion3 over the Integra+Motion2 OR if you already own the Integra+Motion2 ?
I’m interested in the 04 for long range. Any idea if the range would be longer with the goggles 2 or 3? Leaning towards goggles 2 since the antennas can be changed easily, but not sure if that would be the longest range option.
I know you covered the 03 RF power in the video but did you check after updating the 03 to this new FW? Is there any chance the new update eliminated the need for an arduino armer for 03?

Thats my favorite flytribe shirt! appreciate the great info, as always!
Thanks for the clarification Ian 👍🏻
4:10 Just clarify, previously it was possible to use the Goggles 2 as Master and Spectate to the Goggles V2. Is that still possible for the O4 system?
No. The reason G2 and V2 could was it was the same RF system. You can not spectate between O3 and O4.
Is the ham file necessary in the US with the 04 pro?
can I attach a better antenna on the O4 Lite?
Is the FCC hack really moving the goggles over to the US mode or is it more a “power/channel unlock”? In Europe, I heard that the 5.2Ghz band is available/used. Is this still the case after the file is placed ?
I believe it fits the tanq frame from Rotor riot as well
Nothing to say about the lost of the 4/3 @ 100fps at 2,7 k ? I fly at 4/3 , and i have only 1080p @ 100fps.

How about compare Air Unit "lite"and caddx ?
At 2:35 I expected you to throw back the 2 dji remote controllers...😂😂😂
8:20 - i did not know about the arming command to kick O3 in full power mode. how would i do that?
Connect 03 to a flight controller
@@grampafpv ah ok, well i do that with all my air units, thanks!
There are also products like the "O3 Armer", and I believe ELRS either already can or will be able to also send this command with ELRSv4.
I´m very sad to know that v2´s are not compatible. Dji, pls consider v2´s update to bind with new O4 system!
What does the wiring look like on an RC car? Can I connect plus minus from the air unit directly to the battery cables that lead to the ESC? or is it better to take a second battery?

do the O4 have linear Antennas?
is the power level, you can chose, a max value of dynamic power or is the o4 always transmitting with this value?
It's always at that power
What is the advantage of using low powers? since everyone wants to use everything at its maximum. thanks for the audio I.A always
you save energy. and why should you transmit always with full power, if less is still enough?you only disturb other pilots, wlans etc.

The lite unit is almost unusable with such a narrow FOV lens. I hope (but don't expect) they'll eventually sell an updated version with a wider FOV.
Does it matter which goggles are connected for low power mode to work correctly? i.e.: does it work correctly with Goggles 2?
thanks ian, can we use the o3 naked whip antenna on the o4 pro ?
I cant wait to tey the o4 pro with long range and see how it compares to my o3.
What is the difference in penetration distance compared to the 1200mw of the v2 goggles and air unit 1?
You’re legend. Thank you. So technical but no ESD protection?
Thanks for a nice video! Normally, O3 will overheat its processor without moving air. Does O4 overheat on the ground like O3?
