I donāt think thereās a proper way to do a patch job so Iām wary about giving advice. You can wetlay CF cloth with laminating epoxy easily there are some good YouTube tutorials, itās just difficult to do a pretty job. You might need to sand the enclosure first to get good adhesion. Stiffness not matching might be less than ideal.
I had pretty good luck with skinning a thin and weak enclosure in a few layers of cf, itās been tough enough to hit curbs and the steep edge of a road, supporting my weight scraping all the way to a stop, and adding an aluminium patch with leftover araldite 2014 thereās 1.5mm deep gashes and itās still on.
Itās slightly flexible which is often more preferred on a deck that flexes but also itās transparent to radio, whereas carbon is opaque to radio. Carbon can also short batteries and other things, and glass wonāt. The only thing worse about glass fiber, is itās less svelte.
That makes perfect sense ā super helpful, thank you. I actually have another carbon enclosure on hand too. Is best practice just to insulate everything with fish paper in those cases? I honestly didnāt know carbon could short out the batteries.
You can add a gel coat on the inside if it doesnāt have it already, and use fishpaper, both of those work, I would do both honestly. There are other ways as well but fishpaper is really good.
