Carbon Cubs have had some broken tail wires. All the airplanes designs from the 1920s, 30s and 40s that had an adjustable tail for trim had the load attach point for the wires on the center of the stabilizer rear spar, which is the center hinge line for the stab. So that when the front of the stab is going up and down with trim changes it does not move the location of the wire attach point. The Carbon Cub moved the wire attach point to the stab/elevator hinge pin. That looked like a simple solution when I first looked at it but now I think it's going to be a problem area thats going to have to be redesigned by CC. I'm no engineer, what do you think?
This is what the brackets look like on the one with the broken wire.
Just thinking, looking at this photo above, the hinge line for the elevator is just aft or off center of the rear spar for the stablizer. And the rear spar is the center line hinge point when the stab goes up and down when you trim. So as you trim the stab up the rear spar rotates CCW and the wire/elevator pin goes down pulling harder on the top wire and vise versa when the stab goes down.
