Robart hinges are certainly good hinges, especially on large planes, but the Dubro flat nylon hinges with steel pin work really well on smaller planes and places where there is not enough thickness to accomodate a Robart Hinge. I use the Pacer hinge glue, no extra pins, and wild horses can't pull out these hinges. I seem to be able to get less hinge gap and hinge is less noticable than Robart, but robart looks more scale in some cases. Guess that is why they make more than one type. I am over CA hinges, they work ok but just never liked using them. My $02 worth.
