My misunderstanding...having only seen the thin CA hinges before on the trainer, I didn't realize the nylon ones went internal as well...glad I asked before I glued
I did a quick bench test on some scrap wood, and yeah, you wouldn't want them laying flat on the control surface, you can peel them off pretty easily.
Thanks,

Those nylon ones are almost as easy to install as CA hinges. If you use hinge glue that is. They are a pain if you install them with epoxy, and you can wind up with a disaster. Hinge glue solves all that.
There is a trick that makes any glue hold those hinges very solidly. The holes in the hinge flats. Make sure those holes are filled when the flat is being pushed into the slot. Actually, make sure you got some glue into the slot first, and that you smeared the flats both sides, but those holes are the clincher (pun intended). When they carry a plug of glue in with them, the glue winds up drying and creating a bridge from one balsa face to the other. In a sense, the glue becomes a pin sticking from one side to the other.
Hinge glue that squeezes out into the hinge or hinge gap is easily wiped away. Epoxy isn't. And epoxy that seeps into the hinge ruins it. Hinge glue doesn't. And if you wipe with a wet paper towel, is diluted and removed.
If you've ever fought epoxy this hinge glue will amaze you.
