I am building the Goldberg Ultimate Bipe and I was going to use the "live" hinges that came with the kit. I have never used this type hinge in all my 30 years of building, I almost always use Klett of GP flat hinges but I was doing a pull test and to my surprise the hinge came out of the rudder trailing edge. I did clean the hinge with acetone to remove any mold release and scored the flats of the hinge with 60 grit sandpaper so the only thing I can think of is I did not get enough epoxy in the hinge slot. I have used the live paper/plastic hinges before but the range of movement was a lot less than I needed and the control surface was really hard to push on at it's max through. I have a bunch of Robart medium size pin type hinges but the hinge barbs sticks beyond the wood to a point where the barbs are no longer touching the wood.
I am open to any new or old ideas so let me know what type of hinging you have used in the past.
