Hadron 4 is the new generation of a high-performance PPG wing, created for experienced pilots who expect a sporty character, high efficiency and confident behaviour during everyday powered flying.
Hadron 4 is a wing for pilots who want to move beyond the Nucleon class and are looking for a more dynamic design for ambitious PPG flying, without giving up the comfort needed for regular use.
Hadron 4 develops the concept of a fast XC wing known from the previous generation. The new version has been refined primarily in terms of launch behaviour and flight economy — the wing rises above the pilot more easily and predictably, while its aerodynamic efficiency allows better use of engine power during longer routes.
Hadron 4 is intended for experienced PPG pilots who know the character of reflex wings well and want to move to a higher level of performance. It is a design for pilots who fly regularly and are looking for higher cruising speed, better use of engine power and a more sporty response to steering inputs.
Compared to Hadron 3, the new generation has been refined in areas that have direct importance in everyday powered flying. Improved launch behaviour makes it easier to bring the wing above the pilot, while better flight economy helps reduce power and fuel demand during XC flights.
Strong lateral and longitudinal stability supports calm wing behaviour across a wide speed range. As a result, Hadron 4 performs very well in fast XC flying, where not only speed matters, but also predictability, comfort and reduced pilot workload on longer routes.
In the Dudek range, Hadron 4 sits above Nucleon 4. It is a natural choice for pilots who feel they need a more advanced, faster and more efficient wing, while still wanting to use it for regular, everyday PPG flying.

FET - Flexi Edge Technology
The leading edge is closed to the airflow, and its precise shape is kept with laminated cloth reinforcements, incorporating synthetic rods. The rods make the leading edge stiffer and smoother, bringing improvements in many areas – from easier inflation, through stiffening the canopy in flight to improved general airflow.
Airtakes designed and executed in Shark-nose technology meaning specific, concave shape of the reinforced profile area at its leading edge (the name comes form the very shape, reminding shark’s nose).
Leading Edge Double Reinforcements are additional reinforcements between the cells, which stiffen the leading edge and keep the profile ‘clean’ during the flight at full speed.
Mini ribs speak for themselves – they are additionally introduced in the trailing edge between main ribs. Their task is to decrease ballooning (expanding and deformation of the cells) in this vital area af the aerofoil.
Keeping the rear part in shape reduces the drag induced behind trailing edge, thus improving general airflow and increasing airspeed.
DRA – Dudek Reflex Airfoil -applied in PPG wings fully autostabilised arofoil, based on long years of research and experience. In our variant we managed to get rid of typical flaws associated with these aerofoils.
CSG – Canopy Shape Guard – is our unique system controlling canopy coherence. It is because of this system that our wings are equally tensioned, smooth, stable and… simply remarkable.
Capabilities of the laser cutter allow for serial cutting of complicated shape narrow elements in large numbers, their optimal placing in relation to structure of the textile and highest possible precision of cut.
The LE3D uses a system of additional cuts on the top surface of the leading edge along the wing chord, which minimize fabric wrinkling and more accurately reflect the designed shape of the aerodynamic profile in the crucial zones, where most lift is generated. At the same time drag is minimised; all in all the glide ratio of the wing is improved.
A trimming system for additional angle of attack regulation. Used mainly in PPG wings.
This system features replaceable trim straps. After prolonged or intensive operation they need to be replaced, as they get damaged by buckle edges.
A system of lines and pulleys sewn to the appropriate straps, connected to the bar hanging under the harness. It enables smooth adjustment of the angle of attack during the flight.
The 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.
2D system is generally similar to the classic one – pilot has but two main steering handles to steer. However, it’s operation is significantly different. Due to division of main steering lines (there are two for each side now, with one of them going outside of the pulley), an experienced pilot can modify steering progression according to his own preferences.
Indigenous way to hold the brake handles at the risers that keeps them firmly in place, while both attaching and releasing goes smoothly and easily. Used in most of our handles (TCT, ACT, SCT).
