The Tettra Pull-Pull system is easy to
install. Simply cut the copper tubing into 4
equal parts, to use as crimps. Next, thread
cable through the eyes of the servo arm
couplers, then loop it back through the copper
crimps, as shown above. Pull the slack out of
the loop, then crimp each copper tube with pliers,
taking care to keep the loop of cable out of the
jaws of the pliers (see above). When properly crimped,
the cable will remain tight.
Adjust pull-pull
tension by turning threaded couplers.
