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. <SPAN
style="mso-spacerun: yes"> </SPAN>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.<o:p></o:p></SPAN></FONT></SPAN></P>

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.<o:p></o:p></SPAN></FONT></SPAN></P>

<DIV>I like that idea for the elevator setup.</DIV>
<DIV>What type of bell crank is it that you use?</DIV>
