Dudek Cabrio Synthesis, User Manual

We feel safe to declare the Synthesis Cabrio to be the best wing available in 
its class.

The fundamental feature a good PPG and PPGG wing should possess is its 
great stability and tuck-resistance. When this is achieved, the user does not 
have to concentrate all the time on steering, thus saving energy for other 
purposes like navigation, taking pictures or simply enjoying the flight. In 
addition the faster and safer your paraglider is, the more often you can fly.

While the Synthesis Cabrio was designed to retain all features of a 
conventional paralider, application of a reflex aerofoil section added several 
new qualities. First of all, using that profile means that the wing stability does 
not depend exclusively on the pilot's weight and actions anymore. It 
maintains its own pitch attitude, rising and sinking through thermals while 
remaining stable above your head, without need for so much pilot input.

Generally speaking the reflex profile is a special kind of aerofoil section. 
Specific static pressure distribution creates a situation where at low attack 
angles only the wing fore part (some 60% of the chord) is producing lift, 
while rear 40% of the chord creates an effective stabiliser against excessive 
decrease of the attack angle. The trimmer system allows you to considerably 
raise the airfoil’s rear part, thus effectively reducing projected chord and 
surface area by some 30%, giving the paraglider a higher wing  loading and 
increased speed without change in the angle of attack. The centre of 
pressure also moves forward, adding enhanced pitch stability. Such a shift of 
loading gives the wing exceptional tuck-resistance and increases its 
projected aspect ratio, resulting in much better flight data (especially at full 
speed).

Should you require more lift at lower speeds, the rear section can be pulled 
down to restore a full airfoil, effective along the whole chord.

Piloting the Synthesis Cabrio actually reminds flying a conventional powered 
aircraft more than a paraglider.

Below we will try to give you a closer look at some of the remarkable 
Synthesis Cabrio features.

CONSTRUCTION

Synthesis Cabrio is basically a Synthesis, yet a Synthesis that was 
redesigned, enlarged and adjusted to special needs. Retaining the same 
planform it has four cells more, strenghthened structure and enhanced 
rigging. Additional V-shaped mylar reinforcements contribute to exceptional 
durability and perfect aerofoil reproduction.
