For pinned hinges, I've always had an issue with the glue being wiped off the hinge as you insert it into the slot. It always made me leary of the amount of glue that is actually in the slot.
My friend came up with (or at least suggests) using a small syringe (he uses one that came with a tooth whitening kit) filled with glue and flattened on the end to fill the slot with glue.

By the way, he submitted his idea to Tower Hobbies and they gave him a $20 credit for his next order. Something to keep in mind.
