I have been thinking about the advisability of buying a 50 year old Glider and several things came to mind. There were 3, first generation ships, Diamont, Phoebus and 301 Libelle. Two of them used balsa wood wing core and the other didn't use any core at all (Diamont 16.5 & 18) and one used a wooden box spar (Phoebus).

Minor correction, JJ. The Diamant DOES use core in almost all of its skins.. It uses PVC foam, not balsa. But, it DOES use core in its skins.
