I am considering buying a stick built airplane. The trouble is, it has sat up in the owner's garage for about 10 years without flying. I am wondering if the yellow carpenter's glue he used to build it is still strong. Does it become brittle or weaken over time? I am concerned the flexing that will occur while I am flying it might cause the glue joints to break because they have become brittle over time.
