WARNING: Loose, unsuitable or incorrectly tied brake line knots can cause the main brake
line to loosen and then lead to loss of control of the glider.

Incorrect adjustment

If the brake lines are too long, the speedriding glider reacts slowly and is difficult to land. The
brake lines can be adjusted during flight by wrapping them around your hands which will
improve the flight characteristics. Adjust the brake lines to the correct length after you have
landed. Changes to the braking distance should always be made in small increments of no
more than 2 to 3cm and must be tested on a training slope. The left and right brakes must be
adjusted symmetrically.
If the brakes are shortened, care must be taken that the speedriding glider is not slowed
down in trim and accelerated flight. Safety issues may arise and performance and launch
behaviour may deteriorate if the brake lines are shortened too much.
If the brake lines are too short, the following risks could arise:
there could be an early stall
the glider does not launch well and there is a risk of deep stall
the glider exhibits dangerous behaviour in extreme flying
the trailing edge of the glider is braked in accelerated flight which, in an extreme
case, could cause a frontal collapse
WARNING: Environmental conditions can also lead to the brake lines shortening. You
should therefore check brake line length regularly, particularly if there is any change in
launch or flight behaviour.
