BTW, last time I wanted to stop pushrod bending, I didn't bother with pieces of tubing. A piece long enough to reach from the exit hole in the rear of the fuse almost to the rudder servo worked great.

Pulled the clevis off at the rudder end, and ran the tubing into the exit hole over the pushrod to about 3-4" from the servo arm. Put a brace on the tubing right inside the fuse at the servo end. Used a semi-hatch halfway to the tail to put in a 2nd brace. Pulled the wire then so I could glue the tubing at the exit hole. After the CA set, the protruding stuff was razored flat to the fuselage side. 3 supports and a professional looking job that took maybe 15 minutes.
