So, just like how pretty much every other drone manufacturers drones already work. Somehow people only give DJI shit over this and develop a curious blind spot about everybody else.

It is trivially easy for anyone with thumbs to kit-build a drone with no regulatory compliance whatsoever, in nearly any size, with absurd range and capabilities, for just a few hundred dollars. Despite that state of affairs having been the case for years, this has mysteriously failed to cause the Earth to fall out of its orbit into the sun.

IDK, most of the kits require soldering (because the industry is fundamentally braindead) and if you go look at the various online communities, you'll quickly see that this is one hell of a filter.

i'm scared of the magic cancer smoke

Just get the lead free solder and no clean flux, it's much less cancer

Oh 100% magic. And SMT hot air soldering is voodoo magic

Yeah that's the real answer...

Yeah lead free solder is perfectly fine.

Where I live, lead solder is even illegal to sell and buy unless you have a permit which is impossible to get for individuals

Lead free sucks ass and you can pry my leaded solder from my cold dead hands.

Seriously just wash your hands.

Fumes don't contain lead, it's not nearly hot enough. Those fumes are flux burning.

[–] [email protected] 1 points 3 days ago (1 children)

That's good.

But I still don't get why someone would willingly use lead when lead free works great.

I mean the RoHA for example exist for good reason.

Leaded is objectively better for everything except health/pollution. Which is the point of RoHS.

Leaded solder has a lower melting point, flows much better, easier to visually see bad solder joints, and doesn't form whiskers. Also less brittle, so cracked joints are less likely.

Sure but it works well enough if you have just a little skill.

[–] potatopotato 6 points 5 days ago

Interesting, I haven't heard about that.

For systems that...may experience some degree of vacuum...it's common to use lead solder still because it doesn't tin whisker so unfortunately it's still around for some of the stuff I've worked on.
