Apex DJI O4 Lite Lens Mod XT60 Mount Kit | FPV

I fully converted my Apex frame to the DJI O4 Lite system and designed a few custom TPU parts – including a mount for the O4 unit and a Mario5-inspired XT60E plug holder (panel mount version) with antenna mounts. The parts were designed around the knockoff, but they should also fit the original ImpulseRC Apex just fine – same mounting dimensions.

For the lens mod, I used the DJI O4 Lite Gai Ping Lens Adapter (M12):

I modified the adapter to fit an M8 Caddx Polar lens (FOV 165°). It works visually, but I’ll probably go with M12 next time – image quality is a bit cleaner.

You’ll need M1.2 x 4 self-tapping screws for the lens mod – I reused some from an old lens.
You’ll also need an XT60E (panel mount) connector for the XT60 holder to fit properly.

Since the Apex is built for freestyle, I added the Axisflying CNC case and extension cable for extra durability. You only need those two parts from the kit 👉

I used an O3 antenna since I didn’t have another one around – only connected one port, but it works perfectly fine.
I also included a front standoff mount for the RP1 Radiomaster ELRS antenna.

Lens adapter printed in PETG, the rest in TPU.

Parts are split across multiple build plates so you can mix and match as needed.

Have fun & happy flying! – McFly.fpv
