Dudek Snake, User Manual

NOTE! 
Please read this manual carefully before your first flight 

Very important!

Before use it is vital to check in which configuration the steering lines and pulleys 
are currently set (lower or upper hangpoints) and adjust them to your preferences if 
necessary.
The risers have three points to fix the pulleys on – lower, middle and upper one 
(see risers on page 11). On each main steering line there are points marked, 
to fix the steering handle corresponding to the middle position of the pulley. Position of 
the handles should be adjusted according to your pulley setting. 
Steering lines must not not push down the trailing edge when not operated – this must 
be observed in all possible configurations of trimmers and speed-system. Steering lines 
must have a couple of centimeters play before they engage affect the canopy (see 
section 3.1 on the proper adjustment). For sake of safety it is always recommended to 
set the brakes rather too loose than too tight. Make sure they are set symmetrically, too. 

Ill-adjusted steering lines may cause you to misinterpret the canopy’s 
behaviour in flight, and may cause dangerous collapses in accelerated flight 
when set too short.

Speed system of these risers is by default integrated with the Power Attack

system.

During numerous tests it turned out that in case of certain slalom

tasks it is better to 

restrain the trimmer a bit, so that it won't become

totally released when acting jointly 

with speed. Such settings make it possible to use the main brakes for

steering in 

accelerated flight, without collapsing tips.

Correct operaiton of the Power Attack requires releasing the trimmers beforehand by at 
least 6 cm and not more than 9 cm.

Using the speed system combined with Power Attack results in big surge of

the sink. 

This can surprise an unexperienced pilot, causing dangerous

situation when close to 

the ground.

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

 CM!

When flying at full speed (trimmers opened / trimmers opened and speedbar 
pushed),  in rough air, it is highly recommended to steer the paraglider using alternative 
steering methods like TCL ( (Tip Control line) and conected TST toggle .
With increasing speed an effect of „inverting” the profile when trailing edge is being 
pulled down emerges. That effect can cause dynamic collapses, especially at full 
speed.
The safest way to change your course at high speeds is to use the TST and TCL lines, 
or (in the order of safety) the outer lines of the 2D steering system. Any steering inputs 
should be smooth and easy, without sharp and/or deep movements. Such actions can 
dynamically change pressure distribution over the airfoil, leading to collapses.

These warnings affect every paraglider and the Snake XX is no exception!
