DAVINCI GLIDERS / HULA

6. Lines
7. Accelerator system
They come in different diameters of Kevlar and Dyneema with sheathed cover. They must be inspected
every 100 hours or 12months maximum.
In the case of Brake lines, it was cut a little longer, so every pilot can adjust it according to his personal taste.
But you must always leave 10cm before the brakes line starts acting in order to avoid trailing edge
deformation when the wing is fully accelerated. In case the brake handle comes loose during flight or any
brake lines are cut you can use the C riser softly for directional control instead of the brake line.
The accelerator has been limited in travel up to a safety point, however, you can gain 8-12 km of extra speed.
The speed system length is 12cm (S to L) and 10cm (XXS and XS).
You have to adjust the harness to the speed system so you can use all the speed travel.
To do so you have to be seated in the ground meanwhile you are in your harness and adjust the lines by
pulling up the risers with tension. Another person’s helps to do this is recommended. Make sure also that
the speed bar is not pulling down the risers when you are not using it.
Once all the gear is rigged you have to test the whole speed travel in calm air. The use of the speed system
reduces the angle of attack and the canopy may be more sensitive to collapses therefore do not use near
the ground or in turbulent air and in case you are hit by turbulence remove your feet off the speed bar as
quickly as possible. Always far away from the ground when using the speed bar.
5. Risers
HULA has 3 risers. The A riser has a red cover to easy identifi-
cation. There is another line with red mailon. There is A’ and
is for the big ears.
