Maybe Stereolithography will make balsa-bass wood scale kits that take two years to complete obsolete. Just imagine you order a 1/3 scale Sopwith Camel all framed up by a computer using a supper strong light weight plastic or composite material. All you need to do is cover, rigging engine and radio installation and of course painting your favorite color scheme. When this happens I guarantee the only conventional scale builders will be scratch builders from plans or other means.
