Closer Look

When I took the Runcam Racer 4 out of the box, it didn’t appear to be anything unusual than a typical FPV camera.

Exact same connector on the back of the camera, and you can do all the usual stuff like Joystick control and UART control etc.

But only when I saw that “DJI FPV” ribbon cable in the box, I realized it also supports digital! Taking the back plate off reveals connector for the ribbon cable.

The connection and wire are exactly the same as the DJI FPV camera and Nebula camera.

In the box it comes with a spare black back plate, there is a little hole for the ribbon cable to pass through.

The Racer 4 has the same size and capability as the Caddx Nebula Micro (as well as its Eachine Edition). The weight between the Racer 4 and Nebula Micro is about the same, however the Nebula Micro uses a M12 lens while the Racer 4 is only using M8 lens, bigger lens should always generate a nicer image. The Racer 4 is however about 2 grams lighter than the Eachine edition Nebula which weighs 8.4g.

It comes with an adapter, so you can mount this camera in a frame that only takes full size FPV camera with 27mm width (original camera width is 19mm). This is the one thing that is quite annoying with DJI’s FPV camera because of its non-standard 20x20mm width.

Not An Official Camera For DJI?

Right now, the Racer 4 works fine with DJI FPV system, but according to DJI, the Runcam Racer 4 is not officially supported. Here’s a statement from DJI Support on Facebook.

Caddx, the official partner with DJI who released the Vista VTX and Nebula camera, issued a rather serious statement, saying that they would block the Racer 4’s “UID” in the future so it cannot be used with DJI FPV system.

At the current firmware of the DJI FPV system, the Racer 4 works as expected with the DJI FPV system, but it’s hard to say if they will stop supporting it in future updates, guess we will have to wait and see.

But if you are getting the Racer 4 just for analog, it doesn’t matter at all. Runcam will soon discontinue the Racer 3 so the 4 would be the only option in the Racer series from Runcam.

And even if DJI doesn’t support this camera in the future, you can still use it for analog, so it’s not going to be completely useless. But I really hope Runcam and DJI can work on this together.
