TEST: Skyzone SKY02S V+, the 3D FPV goggles rig from Skyzone

INTRODUCTION

The Skyzone Sky02S V+ represents the new revision of their first 3D solution introduced last year. This bundle represents more a bugfix release more than a revolution. You still have some LCD screen displaying 854×480 with 30 degrees of FOV, a diversity system, a builtin DVR and now a new HDMI input. For the 3D part, both the video transmitter and FPV cam lost some weight and have been shrinked.

Installed on front the VGA camera

-SIDE VIEW

The DC input accepting from 7V up to 26V, so from a 2S LiPo for example

If you plan to power the goggles via a LiPo, select the correspond number of cells in order to display the remaining battery level in your OSD informations

IPD can be ajusted via the two slider buttons

null

A lot of connexion are availble. In addition with the classic AVin/out, you have now a HDMI in in microHDMI format.

null

No problem to display a 1080p source, the downscaling processing is efficient.

null

The builtin DVR whatever the video source in PAL or NTSC format records in 640×480 at 30fps for NTSC source and at 25fps.

For a NTSC source

null

For a PAL source

null

The bit rate is low (~~6Mb)… and the bad news, for PAL source the image is partially cropped to left side and the bottom side

For example, here is the capture screen extracted from the Boscam GS922 (rescaled to 640×480 from D1 format)

null

and compared with the Skyzone capture screen

null

You can notice the few lines are removed from the left and bottom sides. It happened not only for recorded files, it’s also the case for the FPV signal in goggles unfortunatly 🙁 … Maybe a future firmware will be able to solve this point.

The total weight is 52.6g but close to 5g can be easily saved if you connect directly the 3D FPV rig to a +5V input source

Actually, the Vreg accpets only 3S balancer plug

UNBOXING AND TESTING

The first part more dedicaced to the basic of the FPV goggles, for normal 2D usage

The second video is more dedicated to the 3D elements

I had to apply following setting to have both channels in 3D mode

null

The new 3D bundle is working really well. The 3D effect is great for any abject between 20cm up to 5-6m. Above this distance, we can’t really enjoy 3D immersion. No flickerings vcan be noticed in the goggles. The refresh rate is Superior to 60hz. Definitively the 3D rig is more suitable for proximity flights

CONCLUSIONS

A super bundle, almost perfect … no more poor range in 2S like the first edition of the sky3D. The screen offers super pricize and sharp image. One can regret the 30″ of FOV less than some Fatshark model, but personally I found the actual immersion really great. The 3D rig losts a lot of weight and is efficient for proximoty flight. My tears down concern the slight cropping for PAL sources and the low bit rate for the builtin DVR.

PROS

+ Superb builtin LCD screens
+ Complete solution
+ Full connectics
+ 40CH
+ HDMIin
+ IPD ajustable
+ Headtracker
+ Builtin DVR
+ Frontal camera
+ Mask-headstrap

CONS

– PAL sources cropped
– DVR with low bit rate

    Hello SeByDocKy,
    I have a question and I hope you can help me with that.
    How does the internal diversity system work? Are there two individual RX modules inside or is only an antenna diversity?

    Kind regards,
    Steffen Gotzen

    • SeByDocKy says:

      Diversity means in theory two receivers. A micro controller retrieve the RSSI given by each receiver then switch to the stronger channel. In practice the switching is smoothed temperaly to not switch every 1/10th for example but only every second…. to avoid some potential visual artefacts

    Hi friend, I can not get an hdmi connection to my computer. Could you help me with that please? Thanks for the post very good comparison

  • Green says:

    Hi there!

    Thanks for this review, very complete and informative!

    I’m trying to confirm (or not) that two separate FPV sets (VTX+camera) can be displayed?
    Because now with 12% a coupon applying on the goggle alone and not on 3D kit, I would feel stupid to pay more if I could actually achieve 3D flying with 2 separate FPV sets that I could also re-use for other quads…
    Also did you have any problems because of the lack of a fan?

    Thanks,

    Green

    • SeByDocKy says:

      In theory you are right…. but there will be a problem of synchronization between your 2 VTX …. IMHO
