The only guy I know who made his own triple stick was helipilot. Reach out to him if you have any questions. I'm sure he'd love to give you details on what he did and what he would change if he did it again. I know he would have changed some things as I was under his truck with him for 5 hours on top of a mountain trying to fix a shifter that was jammed into low gear after his motor mounts broke.
