I had posted a while back asking about using 2-56 threaded rod so that I could use a clevice on one side and ball link on other side for pattern flying. Learned that threading entire rod weakens it. So would it be safe if i switched out all of my 2-56 push rods and used 4-40 threaded rod instead? Would the extra thickness make up for the difference in strength? Its for a patter plane that originally called for 2-56. Thanks!
