Intro

Goal was to something a little smaller and less loud than my 3" beast - including HD capabilities.

Running 2.5" props on 1106 6000kv and 2-3s lipos, I will try 4s at some point but not sure if the Zeus will explode (can only handle up to 13a current draw on 4s).

I ended up at 103g dry and its a little pocket rocket!

Karl makes awesome frames and he already redesigned the sides for his br 2/3 frames to support a full stack + runcam split mini.

I am going to build a 4" using his br3 frame (which supports 3-4" props) next, using the new sides and a split mini but for the br2 I had already bought a zeus a while ago, so for this build I will stick to the "old" side-plates for now.

3d printed addons include the bumpers as well as some generic standoffs all printed in filaflex TPU.

Some painted highlights on the frame and red M3 screws and standoffs and paracord for the motor wires carry the color scheme further. I wish the runcam split mini came in red/black but for now this will do (maybe I'll repaint it someday). If you don't care about hd - a predator micro is a perfect fit!

R-XSR got depinned and is hooked up with full telemetry running F.Port.

Update after maiden

Had some issues with the split mini freezing at random times during my maiden. Video would still record and the red dot would also keep blinking as well as full OSD and quad control but no fpv feed (frozen still).

After inspecting I did notice that one of the brass nuts from the split stack was gone - not sure if it was the softmounting, the lost nut or voltage issues I decided to fix everything at once.

I changed the wiring and connected the split directly to one of the 5v pads of the Zeus FC, and moved the r-xsr to be powered by the vtx03 5v out.

I also swapped the top brass nuts for nyloc nuts and tightened them properly.

FPV feed was immediately clearer (less horizontal shadow lines) and all problems are gone now - no more freezing!

Initially I had problems with betaflight not being able to start/stop recording by switch - a firmware upgrade on the split mini solved that tho.

Flies very nice both with 2s and 3s 500-550mah lipos :)

Update on the VTX Mount

I ended up mangling my uxii and designed a vtx mount that keeps the vtx super safe, see link below.

The stl is actually a better version that I have yet to install compared to when I took the picture which is still from an earlier draft of the mount.

The new version prints perfectly without supports and gaps anywhere.

Update - new sides and caddx

I ended up swapping the sideplates for the taller ones and the split mini for a caddx. Unlike the split I get practically no jello anymore (even on bent props :D)

Will probably post a separate log later on but here's a pic. Also sub 100g now :D
