Just finished their AT6 which they say to apply CA...  but you need to read closely, and the hinges are hard to pull out so I could see where someone might think they were FULLY pre installed.  I didn't like the plastic "No pin hinge" they used, so I pulled them out and replaced with Micro Carl Goldberg hinges.  I just push them in poke a T pin through the center to make a hole, then push a toothpick in clipping the excess off top and bottom with some diagonal cutters.  I've tried CA, but if it gets near the hinge you're hosed.
