The speed system uses an action/reaction system. Released, the speed-
bar is set to neutral. When the bar is pushed using the feet, the wing
accelerates. The speed can be regulated by varying the pressure on the
bar. Once the pressure on the bar is released, the speed system returns
to the neutral setting.
The speed system is efficient, sensitive and precise. The pilot can use the
system whenever they want during the flight. In the neutral position the
glider will fly at the standard speed and glide. Using full speed-bar, the
wing will fly at maximum speed, but the glide will be adversely affected.
•Released speed-bar: the A, B, C and D-risers are aligned.
•Full speed-bar: the difference between the A – D risers becomes:
16 cm in all sizes
Please note!
The use of the speed system results in changes to the speed and
reactions of the wing. For more information, please see the certification
report.
2.5.1. Speed system assembly
The speed-bar consists of the bar that the pilot pushes with their feet, as
well as the two cords that connect it to the speed system components
on the risers. Once you have chosen the type of speed-bar you prefer,
you must install it. Some considerations:
• You should use the type of speed-bar you consider appropriate,
depending on the type of harness, personal preferences, etc.
• The speed-bar is detachable to facilitate its connection and/or
disconnection to the risers as well as subsequent adjustment.
• To connect it to the harness, please follow the instructions of the
harness manufacturer. The majority of harnesses have a speed system
pre-installed.
• The standard connection of the speed-bar to the speed system is via
Brummel hooks, where two slots in the hooks are interlocked, making
their connection / disconnection easy. However, any connection system
that is safe may be used.
2.5.2. Changing the riser cords
In spite of the speed system having pulleys with bearings to reduce
friction to a minimum, the frequency with which the speed-bar is used
causes the cord to wear and you may need to replace them.
In all Niviuk gliders the speed system cords on the risers are completely
removable and easily replaceable. You can use the Brummel hooks, not
use them, remove them, use another type of connector, etc. It is even
possible to fix the speed-bar cords directly to the speed system on
the risers. This last option makes the connection / disconnection more
laborious, but means the cord has maximum travel without obstructions
or restrictions which is very useful for some models of harnesses.
2.6 TRIMMERS
Using the trimmers:
The trimmers are an adjustable profile modification system. They are
activated by releasing trimmers. To open the trimmers, press the trim
tab inwards until the tape is released. Release the tape until it is in the
desired position. When the trim tab is no longer pressed, the tape
is locked in that position. Colloquially this is known as “releasing” or
“opening” the trimmers.
Once it is locked in that position, it will not release automatically and
return to its initial position. The pilot is solely responsible for opening and
closing the trimmers.
To close the trimmers, pull the tape down using the handle - without
touching the trimmer tabs. Release the handle when you reach the
required position. Colloquially this is called “closing” the trimmers.
The trimmers must be applied symmetrically.
