Axisflying O4 Air Unit Case Set (20mm)

The Axisflying O4 Component Set is a CNC‑machined adapter & cooling kit designed to mount the DJI O4 Air Unit cleanly into your 5″ (or 3″) freestyle/HD‑FPV frame. The 20 mm housing standard makes the O4 much easier to install, while the included heat‑dissipation elements protect your video unit during intense flights.

Features:

- 20 mm standard camera housing: Ensures broad compatibility with frames that support O3/O4 mounting patterns.

- CNC-machined aluminum & nylon components: Lightweight yet durable, to withstand crashes and rough flying.

- Active cooling shell: Helps dissipate heat from the Air Unit, reducing risk of overheating under load or during long flights.

- Slim, compact exterior dimensions: Finished adapter shell measures roughly 33.5 × 33.5 × 9 mm (for the heat‑sink/VTX housing); camera housing around 19 × 20 × 19 mm.

- Lightweight: Total kit adds only a few grams (~8.7 g for housing + heat‑sink).

- Easy install on O3‑compatible frames: No major frame modifications needed; ideal for converting older frames to digital‑FPV ready without hassle.
