Elevator pushrods
The elevator pushrods are kinda interesting....
There is an outer tube (fibreglass or CF) which is secured in place inside the fuselage - pretty normal stuff there. The inner, moving, portion however, is rather novel.
Inside, is a music wire (which we will solder the connectors to). That music wire fits inside a Nyrod inner, and then there are a series of small o-rings spaced along the outside of that Nyrod inner. This whole assembly - wire, nyrod and o-rings - slides along inside the outer.
Perhaps a photograph will make this clearer.
