P.S. The KR-1 and KR-2 are not Rutan designs. They were designed by Ken Rand a few years before the Vari-eze. Construction is somewhat similar, but not identical. The KR-1 and KR-2 were transitions from “wood and cloth” to “foam and fiberglass” construction using a little bit of both. The Vari-eze was “all-the-way” foam and fiberglass.
