Covering Weights and Skeleton Ratios

Once you have a skeletonized airframe part, fuselage or wing, or tail, you need to cover it or skin it with something. The two main choices are some sort of mylar or film covering or thin foam. Here's a table with weights per square inch for various foams and covering materials. By combining these with a skeleton ratio of how much foam material can be removed in the skeletonizing process you can estimate your airframe parts weight and how much weight you have saved.

See Post #11 for an example of how to estimate the weight savings over solid foam from using the skeleton method.
