Hi again,
I noticed that I've got one less CA hinge than required (maybe I misplaced it, dunno). So I've ordered a pack of Great Planes brand CA hinges. They should arrive in a couple of days.

The new ones are the exact same size/shape, but they do NOT have the rectangular hole in them.

I've started prepping, but I have not yet CA'd any hinges in place, so I wanted to ask, given a choice, would you rather use CA hinges with or without the rectangular hole?

As da Rock said, the rectangular hole does serve a purpose, but of course you do then have less hinge holding the surface attached. I suppose too that there would be a difference in freedom of flexing?? There are subtle pros and cons I guess.

I've re-attached the pic of the CA hinges that I have currently for reference...

Thanks for any thoughts on this
