I have a little side project I'd like to try using very light construction to build an 8" diameter or larger low power rocket. I've considered a carbon/honeycomb/carbon tube and a balsa stringer and dope construction and don't much fancy the complexity of all those stringers even with a laser cutter handy. I've seen John Coker's honeycomb rocket article so that seems promising but the times I've tried honeycomb cores for fin stock they came in way over weight as the honeycomb absorbed a lot of excess epoxy. A divinycell foam core should solve that problem at the expense of weight since I can't find anything lighter than 3 lb foam. Does anyone know of a source for lighter flexible foam sheet or have tips for reducing epoxy over the honeycomb? I should mention I'm shooting for a one wrap of 4 oz 1K per layer but I'll build a practice tube or two using 5.9oz 3K just because I already have tons of it. I'm comfortable with prepreg too but couldn't find light 1k fabric.
Thanks,
Scott
