TEST: RT-2/C-600 3D 5.8G FPV bundle

INTRODUCTION

Today, I will review an unsual FPV product for me, a 3D goggles+3D FPV camera combo, to be more precise the RT2/C-600 system. Here, no dual screen and dual channel to display/transmit the 3D, but one unique screen with high frame rate alternating the two views. The 3D goggles welcomes a 32CH 5.8G video receiver. The 3D FPV uses also a unique band so by consequence will reduce the original quality to transmit both views with the same channel bandwidth.

BOX CONTENT

null

+ 1 x RT-2 (with XT60 battery connector)
+ 1 x Colormix C-600
+ 1 x 5.8G linear antenna
+ 1 x DIY cable (for the C-600)
+ 1 x USB to XT60 (for the RT-2)
+ 1 x Menu navigation module with JST connector (for the RT-2)
+ 1 x Instruction manual (English)

OVERVIEW

3D FPV goggles

The RT-2goggles are large and have to be powered from a 2S source via the USBtoXT60 cable. Not that the RT-2 is pure 3D goggles while the RT-2C can be used in 2D/3D modes.

null

The cable offers also a JST plug to connect the menu navigation addon.

null

Via the menu, you will be able to tune brightness, contrast, color, aspect ratio (16:9,4:3) and language

The total screen resolution is 800×480 with a refresh rate up to 75fps so much more than twice 30fps.

-Side view

null

On unique miniUSB is present to power the goggles. No AVin or AVout for example ….

-Upper view

The big white CH sticker in practice is a channel/band selection. A short press selects the frequency Inside the selected band, a long press cycle between the 4 bands.

null

You can find also two sliders tuning the pupillary distance individually.

null

A SMA connector to welcome the 5.8G linear antenna.

-Rear view

null

Surrounding the goggles border, a soft foam is installed and its relatively confortable to wear dispite the weight of the RT-2

null

Impossible to render 3D effect with a simple photo, but the image is crisp. Close distances object (< 5m) are "jumping" foreground versus background. It announced to have a 90 degrees of FOV but in practice I am not amazed of the immersion feeling. It's good but not amazing. null

-Weight

More than 500g for the RT-2… IMHO heavy

null

Camera module

-Front view

null

2.5cm of distancebetween each lens

null

-Rear view

3 USB slots are here: 2 micro and 1 mini. Only the mini is used to power and collect the video signal for the transmitter. I don’t know the role of the microUSB ports … maybe to update camera firmware…. There is also a miniswitch. When turned to the right, the video signal is send to the white wire, when turn to the left, no signal either on the white or green wires. Maybe you have to disconnect the internal camera plug to other port (see below)

null

with the original DIY cable installed via the mini-USB port

null

The DIY cable after JST connector installation

null

With a 200mW VTX attached. The white wire is the Video signal

null

null

-Weight

null

138g …. not really compatible with a 250mm quad.!!! A diet is needed.

null

Disassembling

2 screws to remove and 1 cable to disconnect to access to the main PCB

null

null

null

By default, the camera is plugged to the left connector

null

null

A Samsung chip to encode video frame

null

The main PCB is only 36g !!!!

null

null

the metallic casing standalone weights close to 50g !!!

null

Finally, only the electronic weights just a little bit than 55g

null

I am pretty confident by removing the last metallic element, it will be close to 50g

CONCLUSIONS

3D FPV is interesting only for proximity flights with clearly seperated objects. Here with this combo, the 3D sensations are here but the price is a slightly degraded image versus original PAL/NTSC transmission. The good news, we can’t notice any ficklering linked with the stereoscopic alternance between both sources. Actually the main drawback of the bundle is probably the overweighted 3D camera module, at least for < 250mm racers due the metallic housing. A must to do mod would consist to print a lighter housing.

UNBOXING

PROS

+ 3D effect efficient for close range objects
+ Novolty in FPV
+ Working out of the box, few home work required
+ Tunable pupillary distances

CONS

– 110g 3D FPV camera
– > 500g goggles
– No AVin/AVout

    Bonjour

    J ai acheté ces lunettes et j ai un soucis avec le hubsan x4 fpv h107d.

    Lorsque je suis en mode 3d l image est dédoublé (ce qui est normal vu qu il n y a qu une camera)
    Mais lorsque je switch pour avoir la video en 2d l ecran devient noir et blanc avec un contrast enorme (beaucoup de luminosité) et le signal se coupe au moindre mouvement du drone.
    Par contre en 3d (meme si c est pas du tout exploitable), le signal est super stable.
    Ensuite en 3d toujour, l image est zoomé, c est bizard, mais peut etre normal vu qu il n y a pas 2 camera.

    Mon probléme c est surtout la 2d qui donne ecran noir et blanc avec fort contraste et un signal tres instable.

    J attend un eachine falcon 180 et une micro camera fpv, j espere que je n aurais pas le meme soucis.

    Pouvez vous tester vos lunettes rt2c avec une de vos camera s il vous plait ? Pour voir si vous avez le meme problème que moi.

    Sinon je l utilise avec une lipo 2s en 5200 mah, au cas ou ce serait ca le problème.

    Merci beaucoup

      Avez vous testés avec des sources en PAL ? Je crois que les Hubsan sont en NTSC

      • AURELIEN says:

        Non pas testé, j ai rien en PAL pour tester.
        C est tout de meme incroyable, sur les sites il est marqué PAL, NTSC et quand tu recois les lunettes tu regarde la notice et il est marqué PAL.
        C est quand meme une erreur de pas avoir fait un produit compatible PAL et NTSC

        • SeByDocKy says:

          D’une manière générale, je te conseille de passer en PAL, la résolution est un peu meilleure ….

          • Aurelien says:

            Ok merci, oui je me suis renseigné sur la différence entre pal et ntsc.
            C est que j ai acheté une micro caméra 5,8 ghz pour la mettre sur un inductrix … Et elle est en ntsc …. Ils ne la font pas en PAL.
            Par contre oui je serais en PAL sur mon autre multirotor.
            Je pense que c est important de dire que ces lunettes ne font que du PAL contrairement a ce qui peut etre marqué sur les sites de ventes ou il est indiqué PAL / NTSC.
            Merci pour les réponses en tout cas c est cool

          • SeByDocKy says:

            En fait, j’ai reviewvé que la version 3D… mais bon oui c’est important de signaler que ca marche qu’en PAL
