I understand what your saying about installing the CA hinges with a mark to get the CA hinge straight, but any builder knows to use a pin to find the center of the hinge. They even tell you this in most instruction manuals including the GP Patty Wagstaff Extra instructions. If you use a grease pencil on your CA hinge your asking for it to break. Glue will not stick to grease. You want to get a even flow of CA through out the hinge, even in the middle. The little CA that's in the middle will not make the hinge not flex. In fact glue will not stick to plastic either. So what ever bit of CA is in the middle will break off when the hinge is flexed.

On my 33% and 40% planes, yes I use Robart Super Hinge Points. And there will be certain folks who will debate what glue to use to hold them in, swearing that one glue is better than the other. That's fine, but we don't go around telling these folks they are a novice flier. In fact saying something as pompous as that only strengthens my case. I've even seen some folks use CA hinges on their 33% size planes and up. It's whatever works for them. And longevity has nothing to do with it either. My 'Patty Extra' is over a year old and the CA hinges have not failed.
