Yes, Gtac, those are the ones. I choose to use them only in throttle because of the flexibility issue. But, they do come in very stiff models as well. I just like the idea of having a solid metal or wooden pushrod controling my elevator, rudder, and ailerons. Just my opinion, though. This works excellent for the throttle. However, you have to be able to glue the red outter sleeve to the bulkheads in the fuse, or it will not work right. At least glue them every couple or three inches or so. A little CA works great. Then, that yellow inner rod will bend around anything. Insert the metal allthreads in each end and use. Works like a dream. Hope this helps. Good luck.
