Phoebus A as a first glider
Steve,
Page 57 of the 1997 SSA Sailplane Directory says; "The 16.5 meter Diamond built by FFA was the first all glass fiber production sailplane, not using balsa or other wood sandwich between the fiberglass layers". Have you seen a core inside the 16.5 wing? The 15 meter wings were built by Glasflugel and did use balsa cores.
