Have any of you tried a UV (activated) adhesive?

Sounds almost to good to be true...

Yes. It's pretty good but sets HARD, so if you like CA, you will probably like this. I prefer an aliphatic or straight PVA with a bit of 'give', and sometimes use UHU POR on balsa and foam airframes for the same reason.
Poor points, the battery for the UV LED seems not to last very long, and although the light seems as bright as before, it can than take much longer to cure. It is a thick glue, so probably a bit on the heavy side. You need to be able to shine the LED on the glue line, which rules out some joints.

I seem to recall my dentist used UV curing adhesives. I imagine he tried it in his model airplanes also. If you can find a good medium, ask him about it. It might be easier to ask your own dentist, though.

I've used it to glue translucent foam flaps on indoor gliders. It works really well for that.
