Look at it a different way: Is that 10 pounds worth being 10% stronger? I know the structure shown on the plans is strong enough for a plane flown at 175 mph with a 65 horsepower engine, but what about that same structure flown at 220 mph with a 140 horsepower engine? While I'm thinking about weight, does anyone know how much the plywood skins on the fuselage weigh? Very roughly calculating it the foam/glass I'm using instead weighs 12 pounds for both sides and the floor. I found one reference that said birch plywood is about 56 PCF but I don't know how much I trust that number. Originally I thought that the foam/glass might weigh a bit more, but it's starting to look like it'll weigh less, possibly a LOT less, and I have no doubts that it's substantially stronger. I'll be building a couple of test panels to destroy before I start building, but I'm confident that it'll work best for me. -- Steve N205FT mystic...@swbell.net He who seeks will find, and he who knocks will be let in.
