Advance EPSILON 6 Série Manuel D'utilisation page 48

If, by setting the speed bar line lengths, a first adjustment of the
speed system for leg length and harness does not result in the set-up
described above, fine adjustment is possible by changing the 2 stage
settings on the risers. By moving the knots which locate the gear-
change balls (see illustration) the speed system travel and loading
can be adjusted.
Example: If the knots are moved downwards the changeover
from the 3:1 ratio to 2:1 occurs earlier, raising the loading but
shortening the total travel. Conversely, moving the knots up-
wards delays the gear change, and lengthens the total travel
of the speed bar.
The EPSILON 6 speed system is arranged so that the profile shape
of the wing is fully retained over the angle-of-attack range of the
speed system. This maintains the beneficial qualities of the profile at
high speeds.
