Test report on the "Nucleon xx" motor screen      

Series No.: P119431 from 06/2015 / tested on the 09.09.2015 / drive: FB SportiX / take-off weight 128 kg / wind swaying from O with approx. 10 to 28 km/h - on the ground very strong, gusty air / pilot: Jupp Meis

The company Dudek has already quite a long time the Nucleon in the program, which in its last series as WRC was very well accepted by the market and still will. Now you have an additional "Nucleon xx" constructed here, and where does it belong?? It is also the hadron and the snake in the program.Dudek_Nucleon_XX_1 Now that has also to Dudek Shark nose The new "Nucleon XX" is equipped with this. The profile nose has been completely redesigned here. I quickly realized that there is no modified WRC in front of me. This "Nucleon xx" is completely new and different. That is why the WRC will not be replaced, because there is probably a completely different pilot circle to be addressed here. This new wing is suitable for sporty ambitious pilots. This also seems to be the target direction of Dudek for this very athletic stretch-motor glider. The

"Nucleon xx" is a motor glider in pure reflex design. Fine plastic sticks are neatly worked into the profile nose and do not go too far into the depth. These plastic rods also stabilize the (profile nose) shark nose. This is a pure traction. There are now liner under the motor umbrellas, but these are then Semireflexprofile and no pure reflex profiles as with Dudek. A pure and clean reflex profile needs other distractions to ensure a clean profile. The lines are very robust in the important lower strap area, where there is the cage contact etc. Only further up in the forks will these lines be installed in thinner finishes. I started the "Nucleon xx" in flat terrain forward and backward with strongly changing wind directions. The wind strength on the ground was at the 09.09.15 around 5 to 15 kmh, just a very changing east. In about 300 mtr. MSL I already had a value of up to 28 kmh. I have the "Nucleon xx" Fly free, strong Wingover, ears folding with pull one side and both sides. The steep spiral of 12 m/sec. has flown several times, swinging and rolling and all this with strongly gusty east influences.

Screen lay out and start

It is easy to lay out the "Nucleon xx". As usual with the newer motor umbrellas, simply lay out a slightly curved shape. There is a benefit here that the wing is small and therefore quite manageable. It doesn't even have to be designed very cleanly. The start that set up the wing is a breeze. Easy with closed trimmers that take front a-straps and consistently move forward. The glider simply rises (does not shoot) up to the vertex and stands with little brake. A total of stress-free starting behaviour until the start run. Once the wing reaches the vertex, a sporty start starts, but who surprises it? At 22 m2 area, 128 kg load and little wind, this can not be any different either. We start with some wind 5 kmh to

10 kmh, it all looks much more relaxed. Here is clearly recommended, raise, speed up and then use the brakes with approx. 20 cm at full throttle and already the wing lifts you off the ground. At the startup run itself, one should get used to making only slight tax rashes, as the wing follows very directly to the control rashes. The climbing behaviour of the "Nucleon xx" is quite good despite the small area, would indicate a good middle value. The Dudek standard, elaborate carrying strap is very robust, which also facilitates gripping and overview. There is nothing mixed up, as is often the case with the very filigree and soft belts. The wing top control is operated by a well-grasped loop. I'd like a hose with bullets, but that's just a taste thing. Intuitive gripping with gloves is better with the hose ball grip option. However, this is more of a matter of habit, affecting the control's stop control has no.

Flight characteristics:

The Dudek "Nucleon xx" can be piloted very directly, with short tax paths. The wing hangs very directly on the Brakes and you do not need large control stops in normal flight. Since the wing is acting directly around the axis, there is a need for a more active style of movement in restless, moving air. This does not mean that you have to actively encounter rattling, no just that it does not glide as quietly as a Nucleon WRC. With this "Nucleon xx" you don't have to worry about anything, it is very stable and that with closed and fully open trimmers. I found the factory brake adjustment to be quite successful, as far as the braking distance and the brake grip height are concerned. I personally do not like it especially when the brake handle is almost only with strong (obviously everything is also connected to engine, seat, arm length etc.) to operate arms. The "Nucleon xx" can be controlled easily and efficiently via the brakes with closed trimmers. With a semi-open trimming process, the brake pressure is of course harder. From this semi-open trimming to completely open, the wing tip control should be used. Since we still have the 2-D control over the brake handle, we can also control the brakes inwards, towards the body, quite well. 

The wing tip control is operated by a handle loop which is good (also with glove) to grasp. So we can control the "Nucleon xx" with the normal braking handle (2 D) or even in combination with the wing top control, which makes this wing really manoeuvrable. So we have to make a clear distinction here and ask ourselves what do we want??  The pilot, who sometimes flies a little round or even a slightly larger distance, but otherwise for the Sky Turner not so much left, this "Nucleon xx" is rather not built. This new "Nucleon xx" is very agile, resembles a little of the snake. In restless air, it easily runs around the axis, but remains calm around the longitudinal axis and does not roll. The nick movement around the axis is very low, which has astonished me with the small area. It is always quiet (no roll) with closed and fully open trimmers. The "Nucleon xx" is designed about 22 sqm in size and the permissible, specified weight range is 85 to 120 kg. I've been overloaded with that. The control pressure in the normal working distance 10 cm to 15 cm is very pleasant, it only later increases progressively with larger tax rashes. As with all smaller screen sizes, the stall point is to say that it cannot be as late as a wing with a larger surface depth. Due to the progressively increasing brake pressure, an unintentionally induced stable is hardly possible here. This would have to be done in a very coarse motor. Many large and deep braking maneuvers, did not bring me into the danger of the flow demolition, provided that the brakes are also released again.... 🙂 takes off abruptly gas in flight, the "Nucleon xx" nods slightly, then to give himself at the instant gas to do a little job. The movement of this maneuver around the axis is rather low for this lively glider. Since this "Nucleon xx" is very agile around the high axis, you can feel a little more about the engine torque. However, it was never a problem to control the engine torque even in the climbing phase, as the wing has a very willing curve behavior. As with Dudek, everything is usually produced in Europe.

.... the strap of the "Nucleon xx 22 – 2d"


With the takeoff weight of approx. 128 kg I came to the following speeds, measured at a height of approx. 250 to 350 m/MSL, with GPS. The trimmer completely closed about 41/42 km/h, only so much gas that the height could be kept, so no rise and no sinking. After fully opening the trimmer, the speed increased by approx. 12 km/h, which then lasted about 53/54 km/h. These measurements were made several times and these averaged values are the result. The "Nucleon xx" is thus one of the fast motor screens. The additional foot accelerator has not been tested. I personally am interested in the speed on the glide

Motor screen not at all, but ultimately it is only relevant how fast you travel on the same level. The foot accelerator should only be used with an open trimmer or the 2-D control. This "Nucleon xx" is a completely independent wing and really has nothing to do with the series Nucleon WRC. It is possible to have sporty, rapid ground maneuvers with this wing. My FB Sportix did not have to exert excessive strain on fully opened trimmers and a flight speed of 53/54 km/h despite the small area. When you get out of the normal flight the trimmers completely dissolves, the "Nucleon xx" whistles properly and one is inclined to push gas after immediately. However, this has been done after about 2 seconds, as it hardly requires more gas than closed trimmers. The system has then been recorded and the new profile with its adjacent current is doing the rest. Despite its small area, the "Nucleon xx" has a very good gliding polarity.

Descent behavior:

Folding the ears is quite simple at "Nucleon xx". To do this, take the respective outer a-line and fold it by pulling down this leash, the wing tip. Folding is quite simple, it does not require particularly high forces. When loosening the A-line, the ear mostly rolled out independently. However, it may be that something has to be helped with the brake. The Steilspiraleneinleitung goes very fast and swiftly. The 2-D control allows you to accelerate this manoeuvre by pulling the brake line inward. I have the steep spiral each flew with closed trimmers and with about 30% open trimmers. The trimmers close, weight to the inside of the corner and use the brake with additional (2d control) train inward and after a turn, it goes down.  The spiral was repeated several times around the 12 mtr. Flown. Due to the small area and the high dynamic, the brake insert should be soft and round. During the discharge, it was enough to slow down the inner brake. The Wing is self-directed and returns to the normal trajectory. However, the discharge should be controlled by a few revolutions. Do not simply allow the wing to be pulled out of its dynamic circular with an open brake. When discharged, slightly support the outside of the wing so that it does not stop too much in the part. Landing with the "Nucleon xx" is not a problem, as this wing is very well flaeren.

Because of the small wing surface, however, do not slow down too early at landing, as when loosening the brakes the wing will immediately repeat its speed by dipping. Here, the brakes are a bit sensitive to works. This is a peculiarity of all the very small areas that one should know, so as not to be surprised. Simply let the "Nucleon xx" fly up to a good meter above ground, then slowly use the brakes to flatten the Sinkkurve. So the landing is not a problem either with running or stationary motor.


The "Nucleon xx" from the House of Dudek is a completely redesigned motor glider and has to do with the Nucleon WRC, which you might believe is nothing to do nothing at all. Now the shark Nose (ozone patent) has also been introduced. In order to train the SharkNose in the profile nose, sewn-in plastic sticks are continuously installed over the cross.

The wing is supplied with a motor strap and it is fitted with trim and speed system (accelerator). The wing tips control integrated separately into the riser works very smoothly and is operate together or separately with the brake handle and access. About working with this little

Grip strap can be divided. I personally mean nothing like a hose cover with ball or balls there, because without having to look to intuitively better access.

Pilots who intend to move to a faster and more manoeuvrable wing because they think they are out of their present, should take a closer look at the "Nucleon xx" and fly a sample. As mentioned earlier, such a test flight should not be handled in 30 minutes, that is not enough! It should already be two, three hours Airtime, otherwise the peculiarity of these new wings may not be understood correctly and comes to false conclusions. To get the full potential of these new wings, you just need more time. The new "Nucleon XX" series is available in many colour combinations. The brake grips on the test screen were too small for me, but can be replaced by larger Dudek. The DGAC approval has already been granted.



Who believes to be outgrowing its medium-sized motor screen and want something exciting which should take a look around here and test flying. The latest findings are installed in this wing and the wing is robust, which is not unimportant for the paramotor flying. 

The leading edge is very clean with your shark nose. The sticks that are built there keep them clean in shape, which is also responsible for the light starting behaviour of the plane. The carrying straps, which are custom-built with Dudek, with very light-weight and high-quality pulleys and trains, also have a positive effect here. The "Nucleon xx" is not the right wing for Wenigflieger, but the more a wing for pilots who want a track wing with a lot of dynamism. The "Nucleon xx" is offered in five sizes from 75 kg to 160 kg. This wing is likely to find his friends.
