c-cat

Might have been a good idea to glass all internal's in sheet form before building. Even the sheeting (inside) could have been laminated prior to building. I'm really surprised many don't do this on their max-cat or v builds. Balsa in sheet form tends to absorb a ton of resin which means wetting out the wood before glassing can begin. Otherwise balsa will draw resin from fiberglass making it useless. I would consider first sealing with resin. Then perhaps some carbon veil in general areas inside, along with a medium weave twill for running surfaces. The twill drapes and conforms real easy while building glass weight and strength like traditional glass.
