Assembly

Arms

The arms are attached to the top plate with one short bolt (one from the ZMR kit will do) and 3 long bolts (25mm m3). Use the short bolt in the hole closest to the center of the quad to have as much space as possible to put electronics in. Arm spacer placement is quite obvious.

Side spacers

Side spacers go onto the sides, again with 25mm m3 bolts.

Naze32

Naze is attached to the top plate with plastic/nylon m3 bolts and the spacers. The spacers in this thing are made to get the naze as close as possible to the top plate while still keeping (just) enough clearance to be able to plug a cable into the USB socket. 4mm standoffs would accomplish the exact same thing.

Camera

To use the camera holder you will need to make a cut into the top plate to make space for the camera. You can use my cutout as a rough guide or you could look at the top holder and do a lot better. Make sure the short screw on the front arms is secured before installing the holder as these will be covered up by the holder. Check if the camera fits before installing. I had one exact fit print and one that needed a bit of sanding to fit the sides of the cam board. Install the top half first, using 4 3,5cm screws (replacing two arm screws). Slide in the camera and take out the front screws. Now slide the bottom part in and replace the front screws.

Finally

Wire everything up. Pop on the bottom plate and put on all the lock nuts.
