https://brodak.com/finishing-products/monokote-covering.html This appears to be the monokote that other teams were talking about at comp

Any hobbyist store would sell it, I found that https://rickyshobbycorner.ca has a lot of selection and is in Canada, they sell a variety of UltraCote

Seems like most people find Monokote harder to apply compare to Ultracote
https://www.rcuniverse.com/forum/kit-building-121/5595054-monokote-vs-ultracote.html However, it seems like Monokote holds up better long-term
I think it’s worth using Ultracote for development as it’s easier to get started and will be faster for making a bunch of wings
In the future, we can look at using Monokote for a final product to make it more durable and look nicer (more colour selection apparently)

Alison’s thoughts so far:
These are looking great!
Disagree on 12g being a small weight savings! 16th ribs > 1/8th ribs imo → this is 24g overall for the drone!
Don’t design around prusa dims, we should have bambu labs printer back
Unless you have a reason not to, I would make the cutouts larger but keep more vertical supports (more material in the vertical direction will help reduce bend more than more material in the horizonal direction, think like beam bending)
...
How are we thinking of adding ailerons to these?
How are we spacing out the ribs?
maybe LW PLA spacers?
TE print could probably be bigger, LE slightly thicker
How are the LE and TE prints attached? → glue
End cap + print that bolts to spar to keep wood on aluminum (shoutout Sohee)
You may want to make a test rib to check tolerance of the square cut-out after laser-cutting, talk to the person who does the laser cutting to find out what tolerances you can expect → exact sizing almost never just works for mating parts
tbh you addressed most of my concerns in design updates (no more second spar)
