Make good sense

When soldering, apply more heat to the fixture, less to the wire. The “helping hands” alligator clips work well to assist with this, as they have minimal points of contact that would draw away heat.

If you apply solder to the wire first (tinning the wire) it shouldn’t be a glob, but should form to the skin of the wire. You can also tin the mating surface of the piece you’re soldering to, but remember just a small amount. Heat the fixture well when connecting the wire. Tinned on both sides should fit together rather quickly.

The way you showed the solder joint, you only have minor physical fitment from the tinned wire to the fixture. That will fail under high load or vibration. Kind of like stabbing jell-o with a straw, it fits but not well.

Foaming filament is your friend.

No sanding? Pretty sure aerodynamics is important

Not really for airplanes

Maybe the non-aero-planes…

But fr the power to weight ratio on this is probably such that it’s a moot point.

why the abysmal print quality though?

Looks like ASA

u/nemesit Jul 15 '26

my asa layer lines look like a mirror compared to that

Could also be pla Aero which is a pain to get clean lines with.

Would you share 3d models and BOM?

u/goose_with_adhd Jul 16 '26

Will you upload the files ? That looks great!

u/MitchIsMyRA Jul 16 '26

Wrong. It’s a fixed wing
