Robart Hinges and Tite-bond
Did as suggested above, took 2 pieces of Balsa, four hinges and Titebond wood glue. Let set over night and pull tested the next day. Wood seperated away from hinge point, barbs on hinges still had balsa attached.
Using on Dynaflite Citabria, has 10 flights and the hinges are tight. (Just checked to be sure)
