You know you're doing a great job, OP, when the peanut gallery here has nothing more substantial to add than to critique your em-dashes; greek-latin root word mix-ups despite the common vernacular having moved on from that; and lack of title brevity. Congratulations --- this is a super cool project. I wonder if you've considered using ultralight filaments and 3dprinting the frame? PLA is stiff but brittle, and I know Bambu and a few others sell specialised versions that supposedly weigh less than normal.

Yes. And when your design is simply beautiful as this is: https://karolina.mgdubiel.com/drone/drone-img/05-30-26/cnc_cut_parts.jpeg https://karolina.mgdubiel.com/drone/drone-img/05-30-26/cnc_c...

Most filament based printed frames end up with really nasty resonance; it’s possible to engineer damping around the issue with some clever 3D design if the parameters of the prints are measured, but overall 3D printing copter frames doesn’t tend to be a straightforward solution.

I agree with your first point. The milled fiberglass the author used is a much better UAS frame material than anything from a filament 3d printer due to stiffness and related considerations.

      I will stick up for spiralcoaster. This post is direct and could be interpreted as offensive. Sarcasm both in general, and especially over text is often not appreciated. (It partially depends on culture). Yet, I think this analogy is appropriate here, and I was thinking along the same lines.

      But people do 3d print frames for drones and gliders. It's undoubtedly worse than carbon fibre, I guess, but I found it interesting enough to share that you can buy especially lightweight filaments designed for aeronautic stuff.

I wish we had some standard filament testing that most manufacturers were willing to provide results for. Until that happens, this guy here is probably the next best thing: https://www.youtube.com/@MyTechFun https://www.youtube.com/@MyTechFun Plot twist: many of the "special" filaments aren't special at all or at least very exaggerated.

> the peanut gallery here has nothing more substantial to add than to critique The comments in this thread are overwhelmingly positive by now. Watch out for the contrarian dynamic! (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&query=%22contrarian%20dynamic%22&sort=byDate&type=comment https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...). Needlessly negative comments tend to show up first in a thread, while positive responses emerge over time. (Why? well, I have my theories: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sort=byDate&type=comment&query=reflective%20reflex%20by:dang https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...) It's a fine thing to counteract that with a positive comment, but if you can, please omit the snarky bits (such as in your first paragraph). I know they're tempting, but they tarnish the positivity and substance that you correctly want to see in the discussion - and in the end they "bond" (in the molecular sense) more with the negative posts than with the outright positive ones. Your second paragraph on its own would make a much better (indeed excellent) post - and that is the best way to combat the negativity. (I know my reply here is itself an instance of the thing I'm talking about - responding negatively to the negative bits. Sorry!)

Hi! Thanks for your kind words. I actually had no idea this got posted here, I'm Karolina, and this is my project! Really cool to see some feedback here! I went with CNC cutting over 3D printing just because I wanted to avoid any stiffness/vibrational issues. I don't actually have any prior drone experience, so I wanted to play it really safe with that.
