I have had two attempts at kevlar hinges so far, and both were an astonishing amount of fuss. The first was a complete failure. The second one, on a wing that is in service now, I eventually got to free up and articulate sufficiently freely to fly it. It tooks many hours work, (and lots of cursing) over several sessions, to get them functional. I eventually had to resort to burning them with a heated wire to get them to articulate.

I have a set of wings in the building stage now with kevlar hinges. I'm hoping that they will free up like in the demo videos to be found on utube.
After long discussions in person with successful builders, and much discussion online here, I'm still not totally clear what the problem was. Nor are they, for that matter! The only possible suggestion is that I had too much resin in the hinge line.

I hope you get it right first up, unlike me.
