Seems like there isn't a whole lot of information regarding this goggles. I was actually using this before my replacement 04X Pro showed up. My First 04X Pro had a big piece of rubbish inside the lens/screen. The box was also opened and the goggles seemed like it was a returned item. So I sent them back and getting a replacement. In the meantime I bought the 04O Pro from AtomRC which seems like the same company as Skyzone. The price was good at $360.

The main difference seems like the 04O Pro has 10 degrees less field of view and does not do 720 100 fps. Neither was an issue for me and I actually like the narrower field of view. For that matter I fly analog with a 4:3 format which is a smaller box anyway.

The focus adjustment is slightly different. The 04X Pro I didn't have to go to the hard stop to get a good focus where as the 04O I had to push to the end of the hard stop to see clearly. The screen clarity is just a tiny bit less quality then the 04X Pro. The focus on the 04X Pro is more evenly sharp in all area. Whereas the 04O Pro has some waviness to the image where certain areas are less sharp. Like may be the corners. Since Analog images are never perfectly sharp anyway it is pretty hard to judge.

Here is a comparison table from Skyzone.

 

So I am using both my Skyzone goggles and I actually prefer the 04O Pro over the 04X Pro because of the narrower field of view. I have the SpeedyBee VRX on the 04O Pro and the RapidFire VRX on the 04X Pro. The Speedybee seems to reject interference just a shade better in my backyard over the Rapidfire. Both are way better than the VRX from Skyzone.

Do you also have the Walksnail goggles (Fatshark Dom HD)? I wonder how that compares, it has 46 degrees FOV per Caddx specs. Not sure the specs are comparable between different brands, but if they are then it would seem the 04XPRO with a WS VRX would give the widest FOV and still support 100fps mode.

Yes I have the Fat Shark Dominator HD also. I found that too wide for my vision also. So in the last few days I actually changed the format on both my Walksnail quads to 4:3 instead. I still have a hard time seeing the signal strength on the bottom right hand corner. Not sure if I can move it since it is part of the Walksnail OSD and not BetaFlight.

I also have the Walksnail VRX module to "hang" on either Skyzone goggles. However I bought the Fat Shark because I found the Walksnail VRX module increased the nose weight so much that it is uncomfortable for me. Then again the Fat Shark Dominator HD is nowhere as comfortable as the Skyzone goggles either.

I just can't win on comfort. I am not too worry about the 100fps feature since I don't use it at all. 

I rarely keep an eye on the signal strength, but I guess I don't fly long range. You will see the red borders when signal is low, or you can also try focus mode, then when the edge turns into minecraft you also know your bit rate is dropping. There is a zoom out setting, don't know if they got that working now.

If you ever try out the VRX on the 04XPro, would be curious to know how the FOV compares to your Fatsharks.

I don't fly long range either. In my backyard there is a spot where I get a lot of interference from the metal chain link fence and I did see the signal strength dropped one bar. No big deal so I don't pay much attention to that either.

I tried zoom out mode. It didn't do anything.

I also tried the Walksnail VRX. Problem is that my BetaFlight OSD are all over the place when I did. If I want to use it I have to go into BetaFlight and reset the position of all the OSD data. So I was too lazy to mess with that.

For the Betaflight OSD, you can move the centering around in your goggle settings (so you should be able to match up your VRX to your goggles). However the pain with that is if you fly both normal (ie. BF 4.3 or below) and HD OSD (Bf 4.4 up) then it gets messy as the goggles only remembers one position, so one will be out of place.

Hmmm.....can you explain that a bit more. I am not that well versed with BetaFlight. I am still learning about all the different parameters. I am using 4.4 exclusively.

I built a 3" quad and decided I want to use my Walksnail Pro setup on the quad. I banged my head against the wall for many hours trying to get the OSD working. Finally I stumbled on a YouTube video (I couldn't find it again) that said something about using a preset. I did and it worked. 

With Betaflight 4.4 I have HD box checked in OSD. The OSD worked fine in the Fat Shark Dominator HD even when I switched over to 4:3 format. The OSD centered itself. However when I connect the Walksnail VRX module the Betaflight OSD scooted all the way to the right.

If you only use HD then you should be good. For your VRX, just adjust the centering in the goggles.

Quote:Inside the goggles, you might have to go the the goggles settings, Display, OSD Position and move the red box around to get the OSD screen centered properly.

That's what I thought. I could adjust it for the VRX but that means I have to put it back when I use the Fat Shark. Maybe I can save the OSD setup for the Fat Shark as a configuration file. Changed the OSD to fit the VRX and save that as a separate config file. That way I can swap back and forth a bit easier instead of having to move every item on the OSD screen every time I change.

The OSD centering position is saved on the goggles/VRX itself. They should not affect one another. However if you do swap between the two, you need to rebind the VTX everytime you switch.

Yes I do. I need to rebind between the Fat Shark and the Walksnail VRX but that is a very simple process. 

I read through Oscar Liang's tutorial. I did read it once. I just have to find that red box in goggle settings to see if I can move it around.

I am going to test it now.

Will report back.

Just like Bardwell said, I am going to learn something today and I sure did.

I connected the Walksnail VRX module to the Skyzone 04O Pro. I went to goggle setting, OSD position and sure enough I found the red box. Moved it around and now I have the BetaFlight OSD centered.

The other issue crept up and it has to do with format. The Fat Shark will let me use 4:3 format on the camera and it just resized the display for me. However with the VRX 4:3 format on the camera returned a squished image. I set both the camera to 4:3 or even 4:3 full and the Skyzone to 4:3 from the Skyzone menu and the image is still squished. So I have to use 16:9 on both the camera and the Skyzone goggles.

I think I may like the 04O Pro a bit better than the 04X Pro in that case since the 04O Pro has a narrower field of view. I will test that in the 04X pro just to confirm. Right now even at 16:9 the image looked a bit squished on the two sides. Maybe it will be better looking at landscape instead of my work bench.

At least the OSD is doing ok now. So I have more to tinker. Thanks for the help.

Gee I have an AOS 3" tooth pick frame on the way. I was trying to make a decision to whether to build it analog or Walksnail. I do have a Walksnail 1S setup new in box ready to go in but analog is so simple. Plus I really like the Caddx Ratel Pro camera for flying after dinner.  Decisions, decisions, decisions.

If you like to fly after dinner during dusk I recommend the HD pro camera from walksnail/caddx.  All of their cameras are compatible with all of their vtxs, a bonus with the walksnail system.

Your Skyzone goggles have 16:9 screens (like the Fatsharks), so you should leave them set to 16:9. However you should be able to change the camera aspect ratio to 4:3, that will simply shrink it to fit in the 16:9 screen and add black bars on the sides. The 4:3 FULL I believe is if you have a native 4:3 screen, basically the VRX will stretch the image horizontally to fill up the 16:9 frame, and when displayed on a 4:3 screen it gets compressed back.

As for the Ratel Pro, I read that it has a very narrow FOV, possibly not suitable for drone flying if you are plan on doing proximity flying. I actually find the WS VTX a lot easier to install, basically just plug it in and load a BF preset. There are certainly more steps in setting up analog video (solder camera to FC, solder VTX, setup VTX tables, setup SA or IRC?, etc).

I may already have the HD Pro camera. However I have not flown this quad too late in the evening. I did fly a Caddx Ratel Pro in pretty much pitch black condition outside. The image was black and white but I could distinguish between trees to avoid them. Not the branches but the whole tree.
