The use of ball-collets makes it possible to attach double ball-links to the flybar; this automatically sets the correct rocker spacing.
The double-ball on these ball-collets also provides an adjustment facility for the VR-22 rotor head, as the double ball-link can always be set vertical by connecting it to the inside or outside ball - provided that the linkage allows this; the same applies to the mixer lever.
