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.

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.
Update (14 Jan 2020)
It’s been confirmed that the switching between CE and FCC mode, as well as the 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.
Do let me know if there is anything else you’d like to know!
