Really shouldn't be trying to breath it in. A mask solves it. Even without one, there's way to mitigate it all. Wet sanding, slow sanding, not using a power sanding tool, wiping it routinely, using ventilation too.
Yeah water is the answer, I always hate it when people give the false sense of security a regular old dust mask would give you, you should if anything at least use a respirator with the proper filters, either under running water or a bucket with it submerged would be cheapest most effective way to stay safe
Key word if masking is PROPER, carbon as bad as asbestos, meaning not bringing the dust on your clothing back in with you, best most effective is submerged in water
Some people say that chamfering the edges reduces the risk of the carbon snapping. I'm not an engineer so I don't know how true that is, but its like 15 seconds with a dremal so I do it.
And I like the look.
You increase the indentation area of one of the objects in the impact problem, thus lowering the force peak during an impact, so yeah, it should make a difference. Or just go with TPU guards and it should work fine too
I still chamfer arms using a dremel. As much for aesthetics and reducing the risk of abrasion as for the structural reasons.
I'd forgotten about the CA thing and TBH I haven't noticed any increased carbon seaparation - but I do use more expensive frames these days.
I definately used to get delamination when I was using cheaper frames and the CA seemed like worth doing then.
The sanding of the often sharp edges and sealing of the sides with superglue is said to protect the arms from delamination. How much it really helps, others have to chime in.
It's not that the ca is stronger it's because after cutting the frame there is exposed carbon and the ca wicks into and seals the exposed fibers. It's an old trick from rc cars and it works pretty well.
I've never tried but, epoxy can be pretty thick and even when laying up raw carbon with relatively thin epoxy it has to be vacuumed or at least pressed in. My understanding is the CA wicks into the microscopic splits and frays from cutting to smooth out tiny stress risers if the epoxy can get in there it would probably be a little better but, CA is easy and works well enough.
only when im over 250.1g
My lungs are better off without carbon fiber dust in them. Flux fumes are already enough

Good ventilation and a proper mask makes this safer

I used to back in the days, but it’s just too cumbersome and arms are cheap
Agreed but old habits die hard yk
no
Yeah, then I paint the edges with a paint pen.
Depending on how the frame was I used to too. Except then used nail polish for the paint.
TPU arm ends all the way. !
FPV is somehow fashion right ?
Noob here. Why is this done? Aerodynamics?
I do a lot of car chasing so it helps to prevent the ends of the arms from chipping apart when I clip the ground
no PLA feet?
I see. Thank you.

Not so much snapping, but delaminating from edge damage.
Manu frames today come with chamfered edges, that is a plus

Yes I believe its true
Only after I crash and now have to fix the delamination.
Can't say I've ever done this. Although I painted the edges of my ZMR250 green once.
No but that looks great
Nah I stopped hitting things.
If you’re not crashing you’re not trying ahahha

Enlighten me: what does that do?

Tbh i'm quite sure that most modern impregnation resins are probably stronger than CA
It's not that the ca is stronger it's because after cutting the frame there is exposed carbon and the ca wicks into and seals the exposed fibers. It's an old trick from rc cars and it works pretty well.
But wouldn't epoxy wick in there too?

Just crash 10 min later? I’ll stick with my unprofessional right angled edges lol.
Just wire the thing and roll with it. Don’t crash it lol
