Speed system:

The NOVA RADON can be equipped with a stirrup operated speed system.
ATTENTION: THE GUTESIEGEL CLASSIFICATION MAY CHANGE WITH
VARIOUS SIZES OF GLIDER WHEN FLOWN ACCELERATED.
CHECK CERTIFICATE FOR SIZES!
The speed system affects the A- and B-risers. In normal flight all risers have an
overall length of 52 cm.
When the stirrup is pushed out the A-risers are shortened by up to max. 17 cm,
the B-risers by 14cm, the C-risers retain their original length.
THIS MEASUREMENTS INFLUENCE THE DHV CERTIFICATION.
AN INCORRECTLY FITTED SPEED SYSTEM CAUSES A LOSS OF CERTIFI-
CATION!
How is it fitted?
Most modern harnesses have pulleys attached for speed system fitting. In case
not, it is important to attach pulleys (sewn on tabs) in such a way that allows the
pilot to maximize the power vector of his / her legs without "pushing back" in the
harness.
The NOVA speed system, including "Brummel-hooks" supplied, must be assem-
bled as per instructions.
The speed system cord is firmly attached (use bowline or other nonslip knot) to
the foot stirrup (webbing or alloy bar). The other end of the cord is run through a
pulley on the harness and then in an upward direction to be then firmly attached to
the "Brummel-hooks"!
The length of the cord leading to the stirrup should be adjusted so that it is easy to
put your feet into the stirrup in flight but still short enough to allow full speed
system travel. (Use of 2 stirrups in a ladder fashion can enable you to reach the full
range if your legs are not long enough.)
Ensure both cords on the stirrup are of equal length, to avoid putting a turn in the
glider.
Test your speed system for the correct length of cord on the ground first, with your
harness and risers, before flying with it! The full range is reached when the 2 pul-
leys join together.
