CADDX VISTA HD vs DJI FPV Air Unit: Best FPV digital system

CADDX VISTA HD vs DJI FPV Air Unit: What are the differences?

Last year, DJI announced their first digital FPV system ecosystem which promised to provide the ultimate first-person view experience. DJI’s FPV system has 4 main parts: camera, VTX, goggles, and a remote controller. The biggest problem of their FPV Air Unit was its large size and weight, which makes it difficult to use it in smaller drones. While the CADDX VISTA HD is smaller, lighter, and $30 cheaper than the DJI FPV Air Unit, it provides about the same performance (range and latency).

Featuring the same DJI FPV camera with 1/3.2” CMOS image sensor and 2.1mm, it should be no difference, in terms of image quality, between CADDX VISTA HD and DJI FPV Air Unit.

One of the biggest downsides of the CADDX VISTA HD unit is the lack of on-board recording capability. It doesn’t have an SD card slot like the DJI Air unit. The only way to record footage with the Vista is with your DJI Goggles.

For sure, the biggest advantage of the CADDX VISTA HD over the DJI FPV Air Unit is the smaller size and lower weight. With 20×20/25.5×25.5 mounting holes can be used on smaller Toothpick and TinyWhoop style FPV drones.

Despite that the VISTA HD VTX has only one antenna input, it promises the same range as the DJI FPV Air Unit with two antennas.


  1. I have flown my 5.8 analog with other guys running both air and vista. The air units play fine with analog pilots, but the vista stomp all over my video!!

    • I bought an AU back in May from Visions electronics (web & shipped from Vancouver) and then they went out of stock. seems to be the last few of the DJI branded AU, Everything is out right now and closest you can get is a vista or AU with Caddx’s polar starlight camera which can only do 60fps and has a 16:9 which is not to my liking. I have 2 quads sitting & waiting for the Nebula Pro to come back but don’t think anytime soon – they can’t source the chip in the pro camera that does low latency mode. You can still buy the polar kit from Rotorlab FPV (Vancouver), Airblade UAV (Vancouver), and Rotorvillage (MB). All good shops domestically and i bought from all of them before. They should have this in stock at the moment.

      P.S. I’m in YYC too. Do you know of anyone else locally into FPV? it’s such a small community so i fly alone most of the time, and most ppl from FB are photo drone ppl. Hit me up if you’d like to meet up.


    • Compatibility if you already fly and have dji goggles and non-fpv dji remote then you can bnf all iflight hd or any air units

  2. I’m trying to pairing the V2 goggles and Caddx Vista without luck. Any advice on how to make these two things work together.

  3. I’m about to start my FPV journey, and from research, the HD digital versions of everything seem so much better and efficient than 5.8G analogue, I’m going to get the Dji V2 goggles soon are these older DJI Air and Caddx Vista units 100% compatible with the new goggles?

  4. Anyone using the Caddx Vista in a ground platform (4×4 car) and having issues with overheating? Does DJI Air unit have the same problem? Or maybe the bigger size provides better heat dissipation?
