Does anyone have the knowledge of what the weight difference is between
1 square ft. of 3 mil. plywood and 1 square ft. of 1/2" styro core composite? Or maybe someone could give me the weight of the 1 square ft. of 1/2" styro core composite? Lou |

ups.com... Does anyone have the knowledge of what the weight difference is between 1 square ft. of 3 mil. plywood and 1 square ft. of 1/2" styro core composite? Or maybe someone could give me the weight of the 1 square ft. of 1/2" styro core composite? The weight difference between Okume or Mahogany plywood and that of Finnish Birch is significant as well.

Thats true, the plane I'm building calls for 3 mil Okume. I've come
across a website of a kr2 builder who decided to install the composite/foam instead of plywood. Unfortunatly he didn't weight anything before he made this change. Also he oversized everything on the plane and made quite a few modifications. His plane is overweight, but doesn't know if it's from the redesign, the oversize, or the material change. I like how it's coming out and it promises to be a very slick machine. Lou |

Sure hope he registers it as a "Swiftfoam Special" or something other than a "Rand KR2". I can understand the toothgrinding that a designer suffers when someone substantially alters their design, yet keeps the name the same. 2 mm Finnish Birch is the equivalent in weight and strength to 3 mm Okume, IIRC.
