This is a packet of 24 pre-cut CA Hinges from Great Planes. They feature an improved laminate material which increases CA wicking for a stronger bond.
CA Hinges are quick and easy to work with, and really simplify the hinging process. CA hinges can be used with foam or balsa models.
Simply cut a slot in the centreline of the flying surface and the mounting point, slide the CA hinge into position, and place a drop or two of thin CA glue on the hinge line, and you have a strong and virtually unbreakable hinge.
