It seems to be an old, dead project, but today I found the MakerPlane, a project to build an open source plane design that seems to have been abandoned unfinished 5 years ago. (makerplane.org) The thing that seems really interesting to me is the CNC cut composite construction, but I am having trouble finding information about that construction method. Does anyone know of other projects using that construction? Any books or websites I can find about CNC cut composite (or just cut composite) construction? Thanks for any information you can offer.
