Spartan Twig (Black)

This build was inspired by two things - the Diatone GT R349 which I think looks badass, and zip tie frames which fascinate me.
I wanted a bare minimum, spartan look to it, but with components I like.

The frame is a Twig racerX frame, and the top is made out of 4 zip ties and heat shrink. A lot of the inspiration comes from Youtube: Quad 66 - who also has a great video series on it.

Since you will see all the guts of the quad, I wanted a clean look. A big help was the tbs toothpick mounting board, which keeps wires short and tidy.
Also, I tried to reduce the weight with a mini immortal T and the tbs micro race antenna - sacrificing a little range (but not much)

The build is intended for 2-3S, I think it will perform light & nimble around a 2S 350mAh

Weight without battery is 50g

Any chance you have a wiring schematic for the Toothpick mounting board? Looking for the wiring for the vtx and rx to the fc as manufactures seem to leave this out. Love the build and have a few frames laying around that I may do like this. Awesome build!

You're welcome! And thank you for validating the findings :). It's a neat little board.
Regarding your question; I'm referring to page 8 of this manual:

It says that the Unify PRO32 has a full serial interface which has extended functionality compared to Smartaudio. This interface needs two connections:
Crossfire Nano pad named channel #3 ← Unify PRO32 (CRSF TX = big long one marked as 'B')
Crossfire Nano pad named channel #4 → Unify PRO32 (CRSF RX = regular smart audio signal wire)

If all solder pads are connected to the mounting board, the connection between Unify and CSRF Nano works out of the box. I'm not sure what the 'extended functionality compared to SmartAudio' exactly entails, but I use it for switching channel, band and powerlevel on the Unify without any flight controller connected. To do this, you can use the Crossfire LUA script on the controller. It will automatically show 'Unify Pro32 Nano' in the tbs-devices menu after binding/updating.

Thats awesome . I have the normal lua working so far, but I may try this additional functionality on my next build. TBS cloud is sounding like the glue that is going to tie all this functionality together. It will have the ability if you use the TBS fusion fatshark module, to automatically change vtx/module channels in sync via wifi, among other things. Not sure what the current state of affairs is with regards to functionality, but heres one basic setup walk thru.

Thank you!

for a couple of zip ties and some heat shrink tubing this thing is clean as hell. curious to know how sturdy the camera mount is though. any noticeable jello?

Samw85   Feb 17, 2020 

I have no jello, really happy with the result (make sure you tighten the zip ties good)

not sure about crash resistance, we will see, or hopefully not ;)

some sort of weatherproofing would be a good idea. clear nail polish works for me, a lot cheaper than conformal coating. I'll be getting a twig xl in a few weeks, may end up doing something similar as this looks badass.

This is really cool! Very good use of the zipties while keeping the build clean!

thank you! I'm really happy how it turned out.

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
