Warning the hinges on the kits are not glued but pinned But the pins do not go through the hinges all the way Also the slot is cut 1/8 by 5/8 inch and the hinge just floats around in the gap not very good QG These are the Seagull kits The hinges they use look like the Dubro hinge and come installed and pinned from the factory. If one were to look at the bottom of the wings you would think they were glued and pinned. But the pins pot out just with a finger nail under the head and then the hinge falls out by itself The pins look like the scale rivets that Sigs sells the ends are not pointed just cut flush
