color:navy'>John, I can’t comment on Kevlar. I have only used steel (.021” Sig
control line cable). I also use internal bell cranks to eliminate cable tension
load on the servo mount rubber grommets and shaft. This way I can run the
cables quite snug. Short ball link connectors connect the bell cranks to the
servo. By using different holes in the servo wheel or bell crank I can use the
full servo travel, and reduce the control surface travel without resorting to
non-parallel linkage or transmitter endpoint and accompanying resolution
reduction.</span></font></span></p>

color:navy'>I haven’t been totally happy using dual elevator servos so I cable
them as well, connecting all 4 cables to a single bell crank. It is quite easy
to balance the travel, center and end-points by adjusting the threaded control
horn and cable length. When I started doing this it yielded the tightest system
I ever used.</span></font></span></p>
