Notes

Hexagonal cutouts

The hex-shaped cutouts at the end of the arms are actually the size of an M5 bolt! This means that you can use a ZSplit frame plate as a quick/emergency wrench to install or remove props on another model, or use a spare plate for handling them on the ZSplit itself!

Back plate slots

The two small circles at the middle of the back plate's sides are there to keep Armattan's Universal LEDs in place. It is a convenient solution for adding LEDs to your frame of you feel like it, but without sacrificing the structural integrity of any component.

Top plate slots

The two longitudinal slots on the top plate of the frame are meant for attaching everything that you might need to.

Want to carry a GoPro, a Mobius, a RunCam 2/3 or any other HD camera instead of a RunCam Split? No problem. Tired of having the battery on the bottom and want to take a chance at having it on the top? No worries - just strap it down tightly maybe, upper props are quite close in that case. Want to go crazy and attach a balloon on your quad before getting in a race with your friends? Who am I to judge? Thinking about this, I'd actually endorse the idea...

Screws

The kit includes twelve screws. Eight of them are needed for the standoffs, and the remaining four can be used for screwing down nylon standoffs of the FC's stack. In addition to those you'll need four (or six) short M2 screws to fix the camera to the front plates: they are usually included in the RunCam Split's packaging.

Note: the images above depict the old camera mount plates. The new ones place the camera higher against the top plate, allowing more uptilt and unobstructed view.

Tips for assembling the frame

You should start from the bottom plate: screw the motors in and route their cables. Decide where your ESCs will be positioned and cut & solder the motors' cables.

Repeat for the top plate (on which the ESCs are meant to go on the bottom of the arms) but be sure to leave generous slack for the wires: this way you'll be able to do maintenance of your electronics by unscrewing the top plate and lifting it, placing it vertically behind the back plate in a sort of an L shape. The top plate will behave like a bonnet and let you work freely while it holds the rest of the frame straight.

You have two options to route the upper motors' cables, depending on their rigidity and thickness near the motor itself: if they are flexible enough you can route them in the outer hexagon-shaped cutout, applying slight tension when soldering them to the ESCs to prevent bulging of the corners at the arms' ends. Alternatively you could bend them on the inner/outer side of the upper arms (depending on your props rotation, place them the opposite side from the one prone to prop strikes) and let them head for the FC via the underside of the arms themselves.
