Chuck,
Yes, retired military and law enforcement. I think Joe will agree, don't use the factory 2/56 stuff for pushrods it is too long and too flexible. I used Central Hobbies CF rods with 4/40 titanium ends with Dubro ball links in the servo ends. This setup worked perfectly after replacing the CA hinges with the Dubro nylon pinned hinges as Joe suggested. Very slop free and as smooth as silk. Took a little more time, but was well worth the effort.

And that's all I have to say about that, (Forrest Gump).
