Hi guys,
Maybe someone here know why there is what's looks like as a two versions of the carboon fiber arm?
I attached 2 photos, in eatch one of them the craboon fiber arms looks very defernt? is it the same matirial?

It's the same material just from a different supplier. As is mentioned in another thread

Thanks
I tried to find information about it with no luck.

They are the same quality? It seems like a big deference between the two

Found some info on carbon fiber Weave's On bike's but still interesting. Looks like the larger UD weave is stronger.
I'm certainty no expert but hopefully helps a little

Thanks a lot.
I will look into it

Early batches of Inspire 1 had these filament-winded, "camouflage" carbon fiber tubes, later replaced by more commonly available braided type. There's no clearly defined advantage or disadvantage of one vs another, the difference is in manufacturing process.

The mention of bike companies and filament winding led me to this thread. I am in fact quite familiar with the process of filament winding since we use it to make rims (the others that were linked before do not)

This for example: https://www.venn-cycling.com/en/product/venn-rev-35-tuc-tubular-carbon-rim/

The main advantage of filament winding versus using braiding (not what DJI is doing) or woven fabric (this is what they use) is that filament wound fibers are stacked on top of one another, not bent to go around each other. Thus a well made filament wound tube will always outperform a well made braided/woven fabric tube in terms of stiffness and tensile strength.

Here is a bit more about the winding technology: https://www.venn-cycling.com/en/venn-technology/
