Speed system
It is important that the speed system is
connected correctly, and the length
checked, to ensure smooth operation in
flight.
The link between the foot stirrup and the
risers consists of two cords and two
brummel hooks. The speed stirrup itself is
composed of a foot bar and webbing with
loops sewn on either end to attach the
cords. These cords should be run up
through the eyelets and pulleys on the
harness to connect with the pulley system
on the front of the risers (see illustration).
This illustration refers to the UP harness,
but many harnesses are similar. If in any
doubt, please ask the harness
dealer/manufacturer.
The length of the cords should be set so
that, at full leg extension, the pulleys on
the risers are just touching each other.
Any shorter and the stirrup will be difficult
to reach; longer and the top of the speed
range will be unavailable.
During take off it is advisable to fix the
accelerator stirrup underneath the
harness to avoid any danger of tripping
over it.
Suitable harnesses
The Kibo can be flown with any
harness with the main suspension
point at around chest height. The lower
the suspension points the more the
harness will respond to weight shift.
The recommended distance between
the karabiners depends on the pilot
weight:
<50kg: 38cm
50-80kg: 42cm
>80kg: 46cm
The harness design should also
guarantee that it is possible to
accelerate the UP Kibo up to the
maximum speed.
Please note that different harnesses
can cause very different wing
