Awesome price drop on these great FPV goggles. If you know, you know.
290g Compact and Portable Design
Dual 1080p Micro-OLED Screens
Diopter Adjustment from +2.0 to -8.0 D
1080p/100fps Video Transmission with Latency as Low as 30 ms
Wi-Fi Wireless Streaming Supporting DLNA Protocol
I suppose CASA requires that drone operators maintain a visual line of sight, so drone goggles are illegal to use in Australia, or is there change of the rules recently?
You can use with another person as a spotter legally
I don’t believe this is (any longer) the case. The most recent regulations say that you must maintain visual contact “with your own eyes”. I don’t see any legal way to fly FPV in Australia.
Drone operator doesn't necessarily need to be the pilot.
So i can throw away my meta quest now wooo
Why it's so? Did you use meta quest with DJI before? Honest question as I thought only DJI googles can be used with DJI drones.
And mine is the OG mavic pro, so looking for cheap google solutions here.
Do you need the motion controller as well?
Doesnt list compatibility with the Mini 4 Pro - likely due to different transmission protocols? (O4 vs O3+)…?
They may do a firmware update later to add compatibility - they've done that with the Mini3/Pro from memory, and maybe even the Mavic 2 series with previous goggles as well. It's not been a common thing to allow backwards compat in the past however they have made a few exceptions with their more recent products.
Motion controller isn't required but certainly makes it all come together.
Do the aerials on the headset give you range extension? I have the Mini 3 Pro with the RC controller.
Moved to Walksnail for cheaper air units and more stable latency; no regrets.
From O3 Air? I think O3 Air Unit is superior to anything else.
Visually, yep.
But they still opt for quality over latency.
Walksnail drops quality sooner, to keep latency less dynamic.
Latency is OKish in both. But in penetration tests I saw on youtube, everything except O3 Air loses its shit completely when behing any building.
@nuker: He had zero LOS in that test.
Latency is OK, just notably less stable on the DJI system though.
As i said, better picture, but it achieves that from a more dynamic latency.
I prefer the fixed 'steps' walksnail uses.
Not everyone is latency sensitive, so to each their own.
He had zero LOS in that test.
You need to unpack this, really. Zero LOS is when you sit on your drone, lol. You probably meant obstructed LOS? That's when stuff really matters.
@nuker: He had no line of sight at several points.
Ideally I'd run HDZero on all my quads, but sometimes I value some video error correction.
Of my 6 currently working 5" quads, only 1 has HDzero, only 2 have an o3, and the rest have walksnail.
Im also very used to planning my flight correctly. I would not position a brick building between me and my target.
If you're curious, you can see the difference when packet sniffing the transport streams.

Walksnail drops quality sooner, to allow an error correction buffer (likely in the transport layer, of the protocol).
DJI uses error detection over correction, to dynamically keep the quality as high as possible; but this comes at a cost of unpredictable latency.
As I said, to each their own. I'm a 'predictable performance' type of fella, over all else.
found it. This is newer video than what I remember, newer firmware. Walksnail now gives a picture behind the building, but still very shitty one compared to O3 Air (1Mbit/s vs 15 Mbit/s for O3). In older test Walksnail just lost the video.
Hi I've got a noob question, is this compatible with a TBS Tango 2 controller? I would need a DJI air unit too?
You need O3 Air Unit for this. Then you connect O3 Air to your flight controller (FC) via serial. If your FC runs Betaflight you’ll get nice OSD overlay in Goggles 2.
Tango is irrelevant here, it talks to FC, not to O3 Air or goggles. I use Jumper T Pro ExpressLRS 1W and small ExpressLRS receiver.
Thanks Nuker,
I've been recommended a Dialtone F722 FC/ESC combo, which I believe is compatible with the Betaflight. It's all a bit daunting but glad to know it will all work once connected.
722 is good CPU, other one is H743 but more money. It does not need to have dedicated DJI connector, you can use any serial port for O3 Air. And check ESC max amps is ok for your drone/motors size.
I've had an Air 2S for 18 months and have used it extensively so I thought I knew what I was doing then I read the comments here about TBS Tango, T Pro Express, Express Reveiver, Walksnail etc and I just realised, I am worse than a newbie and know sweet FA.
I can always rely on the amazing smart people on OzB to always destroy any confidence I build up :)
ur welcome! any time lol
Wow! Awesome review and website. There goes another few hours!
Thanks Nuker
