Special attention has been paid to the position, area and shaping of the cell •
openings to ensure high stability over a very wide speed range (ie angle
of attack). Graduated-sized cell-openings help to increase stability and aid
pressure distribution within the glider.
For better distribution of the forces within the canopy, diagonal segmented- •
rib technology is used. The forces in the wing are carefully calculated and
balanced to give a flawless sail presentation and an intuitive feel to the flying.
A special three-level line concept with progressively differing diameters means •
the top-level lines are made from very strong Dyneema Liros DC. All lines have
the advantage of spliced loops giving maximum overall strength, durability and
the lowest possible drag.
Four sets of lines (A, B, C, D) are used for the upper suspension system. The •
upper C and D lines then combine lower down, so the glider has only three
risers. This helps to reduce drag and gives a simple line layout, which pilots
will appreciate during pre-flight checks and on launch.
The main C-lines are connected to the karabiners through loops, allowing for •
easier adjustment when your glider is serviced.
The Golden3 is certified to be flown with a foot-operated speed system. The •
standard speed system comprises two pulleys for each side with a working
range of 13 cm (size 28).
Gradient has paid attention to details too, including: new low-drag micro •
attachment points on the wing tips; clearing holes on the wing tips; split
A-risers with special karabiners; and a new rucksack, inner bag and riser bag.
