/diy/ - Do It Yourself

Thinking of building a long-range fixed wing FPV drone.

Haven't built fixed-wing in over 10 years, and back then I built with balsa. That design was a relatively short wing, but a long range is going to require a large aspect ratio. Is balsa still the preferred option?

Couple of threads ago I said I someone reached out to me and offered to pay me to model a building and print a few copies of it. I was okay with this, and just said buy me a coffee and we'll call it quits.

Turns out they liked it a lot and now want x50 items printed, to which they said they'd pay. Eacg print is ~15 hours and 150g of filament
This job would eat up approx. 40 days of printing on my Ender 3 v2, plus the hassle of not printing much of my own stuff in the meantime. How should I charge for this?
