Help identify this plane
Yesterday I bought this plane at a swap meet. The man who built it just passed away at the age of 86. His son told me he had been building planes from the age of 15. This glider is a work of art really and I hate to even fly it but the son made me promise I would. It has never been flown. The guy had a Graupner speed 600 mounted but I am swapping that out for a Cyclon outrunner. The wings have a definete concave profile on the bottom and every rib must have been hand shaped. The front part of the fuse looks like it has been carved out of pink foam yet it is very strong and hard feeling. I don't know if it was coated with epoxy or what. Maybe someone is familiar with this technique. The main problem i'm having is i'm not sure what he had in mind to attach the wings. As you can see in the pictures there is a wooden biscuit for lack of a better term that the wings slide over and there is an aluminum insert in this biscuit. I hate to blow holes through the wings but I have no other ideas. Does anyone else have any? Thanks in advance.
