technique, while quite reasonable on a free-flying wings as it allows for
quick pilot reactions and reduces sink, is not advisable on reflex-profile
paragliders. When you pull the brakes, the Snake XX profile loses its
reflex characteristics.
If you have a variometer or altimeter aboard – watch it. In level flight it is very
easy to start climbing unintentionally. The instruments will help you optimise
speed your and fuel economy.
Good knowledge of weather conditions (e.g. wind at different altitudes) and
smart use of thermals, convergence or other kinds of lift will help you greatly
reduce fuel consumption and increase flight range.
Trimmers and speed-system operation
The reflex wing airfoil enables the Snake XX pilot to use a wide range of
trimmers and speed-system action. You are free to experiment with all
possible settings, as long as you keep safe altitude.
Speed system of these risers is by default integrated with the Power Attack
system. If you intend to operate the trims independently of the Power Attack
system, you have to disengage the hooks joining the PA and the trimmers.
DO NOT USE THE SPEED SYSTEM WITH CLOSED TRIMMERS OR THE
POWER ATTACK SYSTEM BLOCKED! SUCH ACTION MAY CAUSE
VIOLENT COLLAPSES!! !
CORRECT SPEED SYSTEM OPERATION REQUIRES RELEASING
TRIMMERS BY AT LEAST 6 CM! (especially in lower part of the weight
range)
Trimmer and reflex profile
In the Snake XX, use of trimmer affects the aerofoil geometry. Closed
trimmers result in a profile featuring increased lift and reduced reflexivity (as it
is in Nucleon). Releasing the trimmers increases the reflex characteristics
proportionally.
To avoid stalls when braking with closed trimmers, their movement is
restricted by the tape sewing (Note: it is possible to push the sewn tape
through the buckle with both hands to replace it, but normal operation range
is restricted by said place!).
Speed system alters the attack angle. In contrast to the trimmers, it does not
affect the profile geometry. If the trimmers remain closed, speed system will
act more like in a classic paraglider, inclining the whole profile (with one
difference of not having a stay between A and B risers).
