RE: Linkages, Horns, EZ-connectors, Z-bends Etc.
I have used EZ connectors at servo horn for over 20 years on some 50 planes, up to 150 glow sized planes, but most were 40 to 60 glow at 6 to 8 lbs. Have never had one fail. I use the metal clip not the plastic ones, and leave about 1/2 inch of the wire pushrod sticking past the set screw. Tighten the set screw as tight as possible, rods are piano wire in plastic tubes. Again no problems. Just my experience not an endorsement or recomendation.
