I started a thread recently in the Dynamic Soaring (DS) forum regarding pros and cons of swept versus unswept flying wings designed for DS. I'd love to hear some more input from any of you who may have something to add.

To avoid repetition and confusion, please don't post in this thread but over in this one:

EPP is not strong or stiff compared to others. Wood is very strong and stiff compared as EPP. Mylar is very strong and stiff compared as EPP. Carbon is very, very strong and very, very stiff compared as EPP. The EPP is best for crashing. EPP is not for aerodynamic reasons. The pure EPP structure could not even DSed with no Mylar, wood or carbon. Why use EPP for aerodynamic reasons?
