This is the 6" version of the Tubular frame concept. Actually this frame was the first that i've completed and build.
It has been designed mainly for cruising and long-range. It houses a 4s Li-Ion packs with 18650 cells nicely.
Differences to the 7" version except the size: It allows for either clamping the rods together OR just using glue. I've found that glue is the best and most simple solution, which is why i've made it "glue" only in future versions.
It uses 6mm rods (i used 6x4mm in my build) only. The needed amount of rods is 1,314m.
The length of each rod:
1 x front arms 270mm 1 x back arms 250mm 2 x cross rods 160mm 2 x front stiffener 111mm 2 x back stiffener 126mm
The total frame weight is around 60-65g.
For general info and build tipps, please check the 7" version:

PS: if you plan on building one or would like to get more info, there is a Discord server dedicated to this type of frame. You'll get all the support you need there.
