Maybe I wasn't as clear as I thought.....my explanation is for a set-up where a bellcrank is not needed, and by "stepping" the rudder servo up the elevator pushrod is below the cables, and between them, so is fairly accessible. (Again, talking about the fuse upside down). It is possible this way to get the pushrod and the cables all centered on the fuselage center line, and keep the geometry pure.
