Quote:Great stuff! Thanks!Where did you source your fiberglass Nomex panels from?Making a polygonal UTA from prepared CF-honeycomb sheet using this cut-and-fold technique looks interesting:http://www.acpsales.com/Cut-and-Fold.htmlA variation on this would be to use those pre-scored end-grain balsa sheets, laminate it with CF, and then cut on the outside make them foldable. Applying a non-stick treatment to the pre-planned EGB joints would be needed so that they aren't glued together. After they are cut and bent, an patching compound would need to be troweled end (preferably also resin-based) and covered with CF tape.
