Runcam Phoenix Hd Link Air Unit Dji Fpv System

Remember Runcam announced partnership with DJI a few months ago, to release DJI FPV compatible hardware? Well, they are finally here! The first VTX is the Runcam Link Air Unit, and two new cameras, Runcam Phoenix HD and PhoenixHD Nano.

Runcam Link Air Unit

The Runcam Link Air Unit is IDENTICAL to the Caddx Vista, basically the same thing just under different brand. You can see my review of the Vista for more info.

It’s also compatible with Caddx Nebula Nano and Polar, the original DJI camera. All are plug and play. Check out this tutorial on how to replace ribbon cables and cameras.

It’s currently sold with Runcam’s own camera, the Phoenix HD as a bundle.

Image Quality

Image quality is very similar between the full size and nano Phoenix HD FPV camera. Compared to the Caddx Polar, the image is brighter, the image colour is more vivid and has a warmer tone.

Fpv Camera Testing Image Quality Runcam Phoenix Hd Nano Falcon Caddx PolarThe Nano has a smaller lens, that’s probably why sharpness is less than the Phoenix HD. But the difference is negligible and only noticeable when you really zoom in.

Fpv Camera Testing Sharpness Detail Runcam Phoenix Hd Nano Falcon Caddx PolarLow Light

As a low light camera for the DJI FPV system, the Caddx Polar is probably still the best in my opinion.

If the Polar gets a 10/10, then I’d give the Runcam Phoenix HD an 8. The main difference between these two is the noise level in the dark, the Polar’s image appears to be considerably more crispy. But if you don’t fly at night, then it’s not really a huge problem.

With that said, the Phoenix HD is still a better cam than the original DJI camera and Nebula Nano for low light.

Does it work with the DJI v1 Goggles?

Can the runcam air unit onboard recording in 1080/60 FPS with other camera like nebula pro?

Oscar 23rd February 2022 - 5:21 pm

Yes it can. It’s basically the exact same air unit as the DJI one, just rebranded.

Hello Oscar. There were any video footage of this nano sized camera. So I have ordered it just depending on your review. And after the order it seems like runcam removed it from their website. Do you know what happened ? Why there is no footage available at the moment?
