Review: Caddx VISTA VTX for DJI Digital FPV System

We complained about how big the DJI Air Unit is, and they listened! The new Caddx Vista VTX is a much smaller Air Unit for the DJI Digital FPV system, making it easier to install, and compatible with even smaller drones.

Closer Look at the VISTA VTX

The VISTA VTX is a collaboration between Caddx and DJI, and fully compatible with DJI’s HD FPV System. It’s much smaller, lighter, and $30 cheaper, and yet the maximum power output matches the the full size Air Unit. However the full size air unit can be hacked to do 1200mW, and we are not sure the VISTA can do the same yet.

You can tell the new VISTA VTX is made for smaller FPV drones, the mounting holes are 20x20mm which means it can be installed directly in your FC stack. They do claim to be compatible with whoops and toothpick class, so that’s interesting.

To reduce weight, the VISTA uses only a single antenna, but claim to have maximum 4KM of range at 700mW, which is the same as the full size Air Unit. Not bad at all for smaller drones! However we expect the full size Air Unit to have more reliable signal because it has one extra antenna.

Frequencies are exactly the same as the full size Air Unit, it still uses the same 8 channels. It also supports the DJI remote for radio control if you don’t want additional radio receiver in your drone.

Another big change is the input voltage range, it now supports up to 6S! When DJI was first developing the digital FPV system, nobody was running 6S back then, and it was too late for them to change the design when the system came out. It’s great that they fixed it  in their latest product.

You have to solder your own wires to the Air Unit. The solder pads are pretty large for easy soldering.

It uses IPEX (U.FL) connectors for the antenna, and they provided a holder to secure the antenna connector.

No SD Card Slot / 1080p Recording?!

One of the biggest downsides with the new VISTA air unit would be the lack of recording capability. It doesn’t have an SD card slot, and therefore you can’t record 1080p HD footage inside the air unit, you can only record footage in your DJI Goggles.

That means the best footage you could get with the VISTA is only 720p 60FPS or 120FPS?

Another concern with the lack of SD card slot is that you cannot change FCC/CE mode, which means if you are from Europe, your VISTA VTX will be locked to CE mode. With CE mode the max output power is limited to 25mW. In order to use 700mW you have to change it to FCC mode and so far with the full size Air Unit, it requires an SD card to do so. Not sure if there will be an work around for the VISTA, I hope so.

FCC Unlock & 1200mW Power Hack

It’s been confirmed that the switching between CE and FCC mode, as well as the 1200mW power hack can be done by accessing internal storage via USB cable.

Power up the VISTA, then connect the USB cable, an external drive should pop up on your computer. Then put the .txt file in there as usual.

    I really want the caddx vista on my emax buzz to get high quality footage and low latency, but I dont want to buy the expensive DJI goggles. Is there a way to stream the footage to a tablet/phone, some kind of receiver?

    to set unit in FCC mode even in Europe, just spoof your position in the PC with assistant using a VPN. set the PC like it is in north america or canada, check with, then connect the unit (s) to the assistant. both air units and googles. works perfectly. at least with my units in Italy. spoofed position with VPN and it goes like a charme

    Also. Beware for european user, the SD card trick to change the power to 200/500/700 will not work here. Hello glitches with 25mw

    @Oscar – what you’re thinking is an SD Card is the side of one of the heat spreaders on a chipset. There’s no SD Card slot on this unit.

  5. Jim Tapp (Protonus)

    There’s no MicroSD Slot on the Vista, so there is no on board recording. Recording will be goggle DVR only, which is 720p 60fps.

    An important note is that the camera cable is now 2cm shorter and lacks the insulation over it, that the stock air unit camera cable had. The back of the camera is changed out for a black one as well likely due to this cable change. Why they did this I’m not sure but I suspect an OEM or racing circuit approached them with these asks.

    The power output is listed as being the same as the normal Air Unit, not sure why you noted diminished power output. We assume that there will be less penetration / bandwidth behind obstacles, since there is single antenna now.

    Max range should be identical. The air unit has a technical limitation of 4 mi / 6.4 km – the system won’t work farther than that. If you have good enough antennas on both ends, I see no reason the Vista won’t go the same distance.

      Thanks for the info I was misled by the image as there is no mention of the lack of SD card slot.
      The full size Air unit can now do 1200mW, so far we can only assume the VISTA can do up to 700mW due to the lack of SD card slot.
      Having two antennas we should expect better signal reliability.
