Quadmula DJI O4 Air Unit (Lite) - Camera + VTX Mount

I wanted to mount the new O4 Air Unit (Lite, not Pro, there are plenty of options for mounting a Pro) onto my Quadmula Siren F3.5. Unfortunately it was already at 250grams with an analog camera and an o4 Pro would have pushed it over 250g. The o4 lite is only 10g so this seemed the ideal choice.

However, there are almost no parts and guides for the O4 Lite yet so here is mine:

• You will need to replace the standard mipi cable between the VTX and the camera with a longer one if you want to mount the VTX at the back. A 15cm or more cable does the trick. I got mine from Amazon (the Runcam one) but any other mipi cable made for the O4 or the O4 Pro will work. 
  • (I originally tried to do a triple stack: ESC+FC+VTX and the o4 overheats in no-time so save yourself some time and keep the VTX in the back)
  • Carefully remove the glue on both side (camera and VTX side)
  • Replace the cable
  • Make sure to re-glue both side as the mipi cable doesn't stay in place by itself. I used an epoxy glue but a glue gun should work as well if you are careful
  • The camera side seems to have a connector “adapter” so make sure all 3 pieces are glued together (cable+adapter+camera).
• Print two of the of O4 Air plates (one regular and one with mirroed X). This is straightforward to install (you want the cable to come out of the camera at the top)
• Print four of the Screw O4 VTX. Quadmula should have given you M1.6mm screw to attach the O3 VTX originally, you can reuse those screws and you don't have to buy M1.6 nuts. (or you can, this will probably be longer-lasting, I was lazy and had a 3D-printer).
• Run the cable ideally between the bottom plate and the ESC. Alternatively, you can also run it in between the ESC and the Flight Controller.
• You can reuse the antenna holder that Quadmula provided for the analog VTX (otherwise you can find it in their model: https://www.printables.com/model/314165-quadmula-siren-f3f35-series
• Enjoy!
