Default RE: Laminate Thickness

I usually use 1 layer of 48 grm amd then 1 layer 200 grm.
I don't use gel coat but just spray the paint into the mold and lay up on that. Saves weight. About 5 thin coats dusted on. Here in Thailand they make a paint that dries very quickly which is the secret to easy release.
What really stiffens it up is a few lightweight bulkheads strategically placed for wing mounts, tail fixings etc.
Better to use a few bulkheads than make the whole thing heavy.
You can always use an extra layer of 200 around structural mounting point areas.
Wings have to be a glass/foam/glass composite done with a vacuum. Then joined with the spars in place.
