RISERS
05
The risers feature long range trimmers; stronger brake handle magnets; TST and 2D
steering systems; fully adjustable brake pulley height settings and coloured A risers for easy
identification.
The risers are simple and easy to use, the full foot-operated accelerator range
is always accessible irrespective of the trimmer position. Unlike some other PPG wings, it is
safe and possible to use the full range of the speed system even with the trimmers in the fully
slow position without reducing the inherent stability of the profile.
Trimmers
The long range trimmers feature a series of coloured stitching lines to aid the pilot.
The lower green line is the neutral position where all the risers are of the same length. For
take off and good inflation behaviour we recommend setting the trimmers between the two
green lines. When set to the lower green line, the wing inflates smoothly and cleanly, slightly
slower than when set to the upper green line but the wing generates more lift, requiring
less speed for take off. This setting is recommended for lower powered engines, high wing
loadings or high altitude take offs. At the upper green line, the wing inflates slightly faster.
The ‘best’ setting depends on your own personal preference.
The double red stitch lines indicate the maximum limit where it is safe to use the brakes for
directional control without reducing the inherent stability of the profile. When flying faster
than the red line, whether by further releasing the trimmers or applying additional speed bar,
do not use the brakes, instead use the tip steering system for directional control.
The fully slow position is ideal for climbing under power and whilst thermalling or free flying,
the brake pressure is at its lightest and the handling, sink rate and glide performance at its
best. This is the most suitable (safest) position to set when flying in very turbulent air, the
wing is easier to manage and the post collapse behaviour at its most benign. To increase
cruise speed you can use the accelerator system, release the trimmers, or do both.
Due to the long trimmer range you must NOT shorten the factory set brake lengths otherwise
you risk engaging the trailing edge when the trimmers are released.
