Dwango,

I glass ALL my center sections so that the glass extends past the fuselage sides. The width, 3", 6" 12" or whatever, depending on the width of the fuselage, doesn't bother me. I know that I will ALWAYS have a center section that will stand up to the stresses I will put it through. I also don't use epoxy resin for glass work. I use polyester resin because it soaks into the wood for a better bond with much higher strength, rather that sitting on top of the wood.
