I'm trying to fix a broken arm/strut on a Blade Nano and have also seen videos suggesting reinforcing the other small drone I've just got.
Looking at stuff on YouTube etc they often use Welders glue for repair and strengthening. We don't have the same brand in NZ, does anyone know a good product for the purpose?
Super glue wasn't much good and my first try with Araldite didn't work (though I'll have another crack).

Btw are there any dedicated drone/fpv forums lurking around that have NZ specific content?
Searching here found a few questions but not too much activity.

Cheers
Craig

UHU por glue comes up in some Welders glue replacement discussions. It is for gluing expanded polystyrene to various things.

Clean the superglue and araldite off thoroughly first.

Eurochild: Super glue wasn't much good

For everything but a few rather narrowly-scoped situations, you don't want to use cyanoacrylate glue, it's best for bonding relatively wide flat surfaces that fit tightly together but not much else - if you remember the setup for the "every drop holds a ton" demo, that's the perfect artificial situation in which cyanoacrylate glue shines. It can't fill gaps like almost any other glue can, and has low ductility so is prone to fracturing/shattering on impact or even stress. For fixing a broken strut as you mention you definitely don't want to use it.

I have used this stuff before, https://www.jaycar.co.nz/bondic-liquid-plastic-welding-kit-with-case-and-uv-led-light-for-hardening/p/NA1530

UV-cured adhesive is great stuff but the Bondic-branded product is outrageously expensive, you can get the same stuff much cheaper from Aliexpress or similar.
