Overview

This 130mm micro build uses my own frame design, cut out of 3mm carbon fiber on a Bantam CNC mill. This frame design is the 1st iteration, with the goal of easily fitting all the electronics without having to do any workarounds, and keeping everything out of the way of the propellers.

Overall weight was 80g dry, 132 with my battery of choice. Not exactly a toothpick, but then again the arms are really beefy, and the roll cage should give me better protection.

Frame

The design of the roll cage is roughly inspired by the HGLRC Hornet. It uses just 2 spacers, and slots into the bottom plate. Arms are replaceable, which I haven't seen much in micro frames, but I really didn't have a choice because of the size of my CNC mill. I'll call it a feature.

Otherwise, I wanted a lot of slots for zip ties, to give many options for securing parts, antennas, loose wires, etc.

After cutting the frame out of the CFRP sheet, I roughed up the surface in a sand-blasting cabinet, followed by priming and painting. Painting definitely is something I need to do better next time.

Electronics

This is the first time I used a buzzer, and I gotta say, it's annoying to configure and troubleshoot when every time you remove the battery you get a delayed 110 db in your ear. I used the iFlight SucceX micro because it seemed almost exactly the same as the GEPRC Stable F4 mini, which I love and have used before, except a few bucks cheaper. So far I'm not impressed: the VTX won't get out of 25mw mode. Hopefully I'll be able to get a replacement.

The frame was specifically designed to have enough space for the FrSky XM+, with slots for a zip tie to hold it in place.

Motors

I used the 1104s because of weight, and it's more than enough power for this frame. These HGLRC Flame motors have been reliable for me, so I'm using them again on this.
