  • Page 2 TEA lines, or TST handles connected to the ALC+ lines. 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 Nucleon WRC CABRIO is no exception!

  • Page 5: Introduction

    Please read this Manual carefully and note following details: The purpose of this Manual is to offer guidelines to the pilot using the Dudek Nucleon WRC Cabrio wing and it is by no means intended to be used as a training manual for this or any other paraglider.

  • Page 6: The Wing

    2. THE WING Who should fly Nucleon WRC Cabrio? Nucleon WRC Cabrio 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.
  • Page 7 Moreover, the faster and safer your paraglider is, the more often you can fly. While the Nucleon WRC Cabrio was designed to retain all the features of a conventional paraglider, application of a reflex aerofoil section added several new qualities.
  • Page 8 Another feature of the Nucleon WRC Cabrio is the Flexi-Egde technology. The leading edge is closed to the airflow, and its precise shape is kept with laminated cloth reinforcements, incorporating synthetic rods.
  • Page 9 SR-Scrim fabric. Rigging system All of the Nucleon WRC Cabrio suspension lines are sheathed by a coloured polyester layer which is covering a brownish Technora core. Low number of lines required such composition, featuring high strength and stretch- resistance of the lines.
  • Page 10 THE RISERS For the Nucleon WRC Cabrio we have chosen four-way risers equipped with: ELR (Easy Launch Riser) system. This is an specially marked A riser (yellow ribbon), manual speed-system affecting A, B and C risers when engaged, equipped with a handle and trimmer buckle to lock it in desired position;...

  • Page 11: Flight Operation

    General rule is simple - higher hangpoints require longer brake lines, lowerhangpoints require shorter lines. Before you take your Nucleon WRC Cabrio in the air, we strongly advise to try out everything first. Hang up the entire PPG unit with ropes (in case of a trike it is enough to clip the risers in), sit in and have someone pull up the risers.
  • Page 12 Easy Keeper (EK) Easy Keeper is the name of our proprietary system to hold the brake handles at the risers. The strong neodymium magnets keep them firmly in place, while both attaching and releasing goes smoothly and easily. With Easy keeper you can easily secure the brakes in flight, thus minimizing danger of their contact with the propeller.
  • Page 13 USER MANUAL Tip Steering Toggles (TST) ALC+ allows for aggressive turns even on full speed, without modifications of the reflex profile. This is of special importance when flying in turbulences with open trimmer and speed system engaged. Additionaly it is important for bigger canopy sizes, without handle special solutions demonstrating...

  • Page 14: Take-Offt

    The essential difference between Nucleon WRC Cabrio and classic paragliders means that due to its increased tuck-resistance (both during start and flight) and greater speed range it can be safely flown in strong conditions. Generally (and paradoxically from traditional point of view) the faster you fly, the safer is your flight.,...

  • Page 15: Landing

    TST handles can be used at all trimmer settings. 3.2.3 LANDING With closed trimmers Nucleon WRC Cabrio lands like any other paraglider. The brake forces, initially low, are growing proportionally, giving ample warning before stalling. Still you should be careful when flying at low speeds until fully familiar with brake operation.

  • Page 16: Take-Off

    First flights In order to get familiar with your wing we recommend flying with trimmers set slow, because in this configuration Nucleon WRC Cabrio behaves as a classic paraglider. Flying like that try pulling the brakes some until you feel resistance, usually it will be at about 1/4 of the range.
  • Page 17 USER MANUAL back can cause some lines to get in the propeller). Possible tripping and falling is dangerous (and costly due to probable propeller loss!) so this should be avoided at any price, even that of some damaged lines! During launch, when you feel that the strain on both risers is equal, open up full power and lean back to counter the engine thrust, so that it can push you rather forward than towards the ground.
  • Page 18 When the trailing edge gets some three meters above ground and both risers are equally loaded, open the throttle fully. Preferably you should not be using the brakes during launch at all and let the canopy rise as it was laid out. If you see it getting off course, give a delicate counter brake and steer your trike under canopy root (center), while maintaining general take-off direction steady as possible.
  • Page 19 Another reason not to try climbing too steeply is the risk connected with engine failure at low altitude. Although the Nucleon WRC Cabrio in a steep climb does not stay back so much as conventional paragliders do, low speed can easily lead to a stall.

  • Page 20: Level Flight

    When you pull the brakes, the Nucleon WRC Cabrio airfoil actually loses its self-stabilizing features.
  • Page 21 Trimmers and manual speed-system operation The reflex wing section enables the Nucleon WRC Cabrio 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 are on safe altitude.

  • Page 22: Landing

    - so it has to be done right! With or without power Nucleon WRC Cabrio better copes with turbulence on open trimmer. So, if the conditions are rough, it is better to make an approach with greater speed, plan a lot of space (as for a hangglider) and wear that speed off before touching down.

  • Page 23: Golden Rules

    USER MANUAL Landing with power off requires much less space. In case of any doubt, practice the landing until you feel totally safe. 3.3.4 GOLDEN RULES! Never place the power unit downwind of the paraglider. Check, double check and then check once again if there is no fuel leakage.

  • Page 24: Big Ears

    QUICK HEIGHT LOSS 3.4.1 BIG EARS In order to get the big ears you have to pull down the outer lines of the A' risers (usually distinguished with neoprene) by about 20-50 cm. While inducing big ears you should never never let the brakes out of your hands.

  • Page 25: Acro Flying

    On quick and symmetrical releasing B-lines the airflow will reinstate and the wing will surge forward, returning to normal flight. In contrast to classic paragliders, in case of Nucleon WRC Cabrio there is no need to counter this surge with brakes - yet another feature of the reflex profile! CAUTION: see Parachutal Stall.

  • Page 26: Frontal Collapse

    3.6.2 FRONTAL COLLAPSE The reflex profile of the Nucleon WRC Cabrio makes it practically impossible, especially at higher speeds. During tests we succeeded in creating this situation only with fully closed trimmers and using special measures. Such forced collapses can lead to extremely deep collapses, so recovery will require decisive pilot action (short and equal application of both brakes).

  • Page 27: Line Over And Cravatte

    USER MANUAL 3.6.4 LINE OVER and CRAVATTE Nucleon WRC Cabrio is a modern wing which, in order to decrease drag, has fewer suspension lines and greater distance between them. Therefore it's always possible that after a tuck stabiliser may tangle in the lines. Usually a couple of pulls with a brake settles the matter.

  • Page 29 USER MANUAL when packed in a bag, it should not remain in the sun for long. Suspension lines consist of Technora inner core and polyester sheath. Submitting them to excessive loads in flight should be avoided, as it can cause irreversible damage. Keep the paraglider clean, since getting dust in the lines and fabric will reduce their durability.
