Product Description

Nucleon WRC

Nucleon Cabrio WRC is a top drawer, modern PPGG canopy. It is very easy to launch, fast to fly, effective to steer and has wide speed range on trimmers. It will satisfy both pleasure pilots, seeking safe and comfortable sightseeing, and ambitious competitors or record hunters.

Nucleon WRC is the essence of reflex profile in a new costume, applying Flexi Edge technology. Cabrio WRC is stable and safe both at low and high speeds. It is sturdily built of the best materials available.


Slight changes in design as compared to traditional, non-stiffened Cabrio brought to the paralider increased agility. Smart connections between mylar reinforcements and synthetic rods (like in e.g. Hadron) result in easy inflation and stiffer leading edge.

The paraglider launches easily and smoothly rises over your head. With good trimmers configuration and sufficient engine power lifting the A risers may be not necessary (canopy rises by itself) – a veryimportant feature for trike pilots.

Speed ranges of the trimmers have been slightly widened. Top speed was increased too.

Another news is  the ALC+ (improved ALC steering system) – it is more effective and balanced, so that steering appears to be smoother.

Despite rather minor changes, Nucleon Cabrio WRC is not covered by the standard version certificates. Therefore all pilots caring for flying certified paragliders should stay with original Cabrio, which will remain in regular, serial production.

Nucleon WRC is an Action/Reaction class paragider, built around the idea of linear acceleration characteristics and limited reflex at slow trimmer settings. The result is a 100% reflex, solid and comfortable canopy of great performance, exceptionally safe in its class, with handling characteristic similar to classic profile paragliders (in low speed range).

A light version of Nucleon WRC is available too. It was designed with tandem foot launches in mind and was named the Nucleon Duo WRC. It is virtually identical to Cabrio, the only difference being lighter cloth – Skytex 32 Evolution+. In result the inflation and launch is even easier, what is of special importance for foot-launched tandems. Duo’s weight range: 170-240 kg. Note – light cloth is available in following colours only: white, grey, maroon, orange, blue. That’s why colour schemes differ from the standard version – clear that out when placing your order.


Push & Relax Technology

The Nucleon incorporates a number of proven and some novel concepts improving flight comfort and performance.

FET – Flexi Edge Technology


Upgraded Nucleon features Dudek Flexi Egde technology. Precise shape of the leading edge is ensured by reinforcements of laminated cloth combined with synthetic rods, which significantly improve launch performance and protect the paraglider against collapses at high speeds.

CSG – Canopy Shape Guard


Unique system controlling canopy coherence along its entire wigspan, practically eliminating any lateral movements.

Most of all, the CSG oversees three key factors:

  • it forms the canopy, so that its shape remains as close to designed 3D image as possible, with equally distributed loads. Lack of attention here would result in irregular surface with balloons instead of flat cells (unfortunately, stil quite a frequent sight, even owing of ‘renowned’ manufacturers).
  • CSG stabilizes canopy in flight. No pilot likes to see his wing moving like an accordion, especially as it does significantly hamper its performance.
  • CSG improves durability of the paraglider. Simple designs pay for locally accumulated stress with deformations – the most dangerous are those visible as lateral faults on the upper surface between suspension line rows. With the Nucleon WRC that danger is practically eliminated.

CSG consists of following subsystems:

  • VSS (V-shaped Supports) - densely placed diagonal supports, bolstering each rib on both sides (most wings have only one-sided supports). Their size, shape and placement make sure that no lateral folds will occur – a vital point in preserving laminar airflow, especially at high speeds.
  • RSS (Reinforcing Strap System) - an independent reinforcement net on lower surface, strengthening and stiffening the whole canopy.
  • OCD (Optimized Crossports Design) - the intercellar openings of carefully designed shapes, optimally placed between stress lines in the ribs.
  • CCS (Closed Cell Structure) - This is a number of closed cells in the most important places. Its goal is to hinder the backflow from the cells out, thus facilitating their refill and canopy recovery in case of a collapse.

The only flaws of the CSG are the increase in weight (about 1 kg), material- and labour consumption, and of course overall cost. Yet it is well worth the sweat, as in turn we get a no-compromise product of highest performance and quality, able to keep its original parameters for a long, long time.

Laser Technology:

Laser Technology

Nucleon WRC is manufactured in new technology, utilising capabiities of precise laser cutter. The entire production process takes place at our Kowalewo facility, ensuring European quality and personal supervision of the designer himself.


Upper surface is made of Dominico Tex cloth (38 and 41 g/m2 weight).
Lower surface features the same cloth of 34 g/m2 weight.
Ribs are made of Porcher Skytex 40 Hard covered with E29a impregnate.
All reinforcements are made of laminated SR-Scrim cloth.


All Nucleon lines have coloured polyester sheath. Due to low number of lines we’ve made sure they are strong enough by choosing brown Technora core. In this way rigging remains strong and reliable.

Metal Parts:

All quick-links between risers and suspension lines are made of polished stainless-steel, with proven durability and restiance to corrosion. We use exclusively the attested quicklinks of  French Peguet company. In our opinion and that of many other leading companies these are the best products available.

ACS – Auto Cleaning Slots:

On the wingtips you can find dedicated slots, automatically removing dirt from the canopy.

ALCNucleon is equipped with a new version of the alternative steering  system. ALC+ is more efficient and affects the canopy in more proportionate way. In effect steering appears to be smoother. System allows for aggressive turns even at full speed, withour spoiling the reflex profile. This is especially important in bigger sizes, without dedicated solutions plagued by big steering forces and poor agility.

The steering toggle is a red ball, position of which you can easily adjust to your needs and preferences. Additionally, the ball and line system has been sorted out as much as possible, in order to minimize possible tangling into risers etc. Of course you are free to use just the basic steering handles – with ignored ALC ball the whole system will stay inactive.

TEA (Torque Effect Adjuster) 
TEAThe task of this feature is to counteract the effect of engine torque, that tends to make the paraglider turn in the direction opposite to the propeller’s rotation. TEA balances the torque by adjusting the length of some wingtip lines, and it can be adjusted to match you specific combination of paramotor/propeller. Simple to use, effective and easy to toggle on & off in the air.

TCT – comfortable and universal steering handles  
TCTBeside modern look, TCT feature swivels, Easy Keeper system (strong neodymium magnets) and handles offering easy conversion from hard through medium to soft brake handles.

EK – Easy Keeper
ekEasy Keeper is our home-grown way to hold the brake handles at the risers.  Strong neodymium magents keep them firmly in place, while both attaching and releasing goes smoothly and easily.
Exact placing of the magnets on the risers is adjustable.

TRIMTrimmer afects speed range similar as the speed-system (ca. 10 km/h). It consists of a buckle and a properly marked tape (red – slow and blue – fast trimer settings). Trimmer is designed with fast and simple replacement of the worn-out or damaged tape in mind.
