Linkage Length & Setup
Compass Model ball links are build up on
the tight side. This allows you to adjust them
to your personal needs. Use a ball link
sizing tool to adjust the ball links. Clip the
ball link on the corresponding ball where it
will be later and test if it moves freely. If not,
clip it on the ball link sizing tool and rotate it
a few turns in different angles. Test it again
on the ball. When you level the whole
linkage horizontally, the linkage should
almost flip downwards by ist own weight. Do
the resizing in small steps and test the
fitting every time. If any ball link has
clearance on the ball, change it and do not
use it again.

It can damage the ball links and
result in failure. Screw them on by
hand or use special tools.
All ball links must be clipped on the
balls with the Compass writing
facing to the outside.
The length of the
plastic drive tube can
be changed easily by
turning the ball link in
and out.
Check all ball links for clearance
and damages everytime you go
flying and change worn ball links
early.
Tip: You can make your own ball link sizing tool. Just use a Dremel with a
thin cutting wheel to cut two slots opposite to each other into a ball
you don´t need. Stick a screw through the ball and screw a nut on the
other side to fix the ball. You can clip ball links onto this tool and use
it as described above.
