Here is my toughest nose gear linkage. It is on my SPAD Swept-Wing Canard. I love landings and probably do 10 of them every flight. The front of the Canard sometimes slams down very hard. The arm at the front gear also kept breaking on me so I made an arm from a Kitchen cutting board. My arm is jammed into the spring coil of the front gear. Has never broken. The control rod is made of 1/16 diameter music wire and has a coils spring built into it. I always also use a nylon clevis as double insurance for the servo. The rod length almost never requires adjustment.
