Dudek Hadron

The equipment
I tried the Hadron 24, a rather small size for 100kgs of pilot: I usually fly sizes 28 to 31… I flew with an Airfer paramotor powered by Moster 185cc engine with 130cm propeller: a powerful combination offering 75 Kg of thrust. I had enough power for all possible flight configurations, considering that the glider was relatively small and that I would try it with a total in-flight load of nearly 140 Kg, i.e., a wing load of 5.83 Kg/m2.

Racing machine
This glider has four risers to keep the shape of the sail; they are strong and introduce some piloting elements. First there’s the trimmer for reflex, which is not too long and, although it allows us to gain 10 Km/h of speed, its main task is to increase the reflex stability. When we open it the brakes get quite hard, so we’d be better using the auxiliary controls that hold back the wingtips and leave the centre "unbraked". Piloting like this requires some practice. More "pro" pilots, like the French champion Pascal Vallee, have modified the brake system by adding a bar instead of a handle with which they can control the wingtip and the main brake line for a dynamic handling, according to the position of the arms: more open or close to the body.

Flying and turning
In the air the Hadron keeps a straight and precise course; hands free or with some trimmer it is easy and comfortable to fly, turns only by thinking of it. As I increase the speed using trimmers and speed-bar the glider requests precise inputs and slight corrections. I manage to draw my path where I want; the wing turns well, brilliantly! It accumulates a lot of energy and you need to know how to administer the speed bar to transform the energy of the surge in powerful acceleration at the exit of a turn.
Piloting the Hadron in ‘recreational mode’ does not have much complications; the wing turns well and takes you where you ask it for. Now, if what you want to do is slaloms fast as lightning, close to the pylons and cutting seconds at every turn, you have to do some efforts as this glider has a lot to offer yet it is very fast and has sensitive steering. You have to train to get the best performance of it.
Basically, as you increase the speed the small movements are intensified as well as the response to the brake, therefore we have to handle with precision if we want to fly fast and accurately. With the Hadron, over-braking or releasing the speed-bar abruptly can cause a really huge surge.
The brakes have pressure; they are direct and very reactive: even when we fly with the auxiliary commands you feel as if you were holding the wingtips in your hands. This is fine because they tell you a lot about the air. In my flights, when the air was rough I could notice small dry movements that I had to compensate meticulously to keep the desired path. It is a wing that asks you to interact.

Solid and stable
I did not find much turbulence during my test flights, the small bumps I found were unimportant and the Hadron just cut through them. It is stable in pitch, and turbulence translates into small sudden movements. I guess it is less solid than the Nucleon (a full reflex glider) on cruise, but I think that the gain in manoeuvrability is well worth the price of such "loss" of solidity. I have seen the Hadron fly to the limit in demanding conditions, like in the Fly Games World in Brazil, and the wing behaved flawlessly – although it was in the hands of great pilots like the Pole Gregorz Kryzanowsky or the French champion Pascal Vallee.
It is interesting to note that Dudek reduced the reflex section in the Hadron to combine reflex solidity with a super-dynamic turn. This means that you can actually use the brakes of the Hadron even with trimmers fully open. This is not recommended with other models, like the Plasma or the Nucleon.
The speed system is finely sort out; it slides well although it is somewhat hard. It uses strong pulleys and thick braided dyneema lines, so that it’ll never break on you in flight!
Additionally, the Hadron comes with good brake handles equipped with magnets, as well as an anti-par system consisting of a line that goes to the wingtip which we can block in the right position to help us keep a straight course in flight. I must point out that in my test flights I did not need to compensate the par.
Another thing that drew our attention of this glider is that it comes with unsheathed lines; this reduces drag and improves performance, but requires better care - we must particularly avoid the propeller hitting the lines. Now Dudek offers the Hadron with normal sheathed lines and also have a kit of lines for sale in case you want to replace the lines of your Hadron.

The +: Superb turn and good sink rate.
The -: At high speed it is very reactive and requests expert hands.

Enjoy this wonderful video where you'll see Pascal Valle with his Hadron in action:



The new advanced sport glider from Dudek was born in the heat of the slalom comps that bloom lately, and it is yet one more step in the evolution of paramotor wings. This time Dudek put the focus on manoeuvrability and turning behaviour; happily, they also took the effort to provide it with good performance and interesting top speed, with the final result of a paraglider for competition/slalom which is also versatile and fast, and does not require a super powerful paramotor.
For this test I tried a size 24 Hadron loading 138 kg. We noticed that this wing can be speedy and efficient in slalom turns, but we were also surprised to see that it does not require excessive engine thrust; it also cruises well, with high stability, it is easy to fly and offers good performance despite being a small size. The first thing that crossed my mind is that this glider in a bigger size may be interesting for the traditional paramotor competition as well, so in my opinion it should not be labelled exclusively as a glider-for-slalom.

Inflation and take-off
The Hadron has a balanced, straightforward and rapid inflation. It rises in one piece, more or less abruptly as the trimmers are more or less open, so you’d better not open them much (unless you're taking part in a race where time opens at take-off, like the Fly Games World). In "normal" mode, trimmers on neutral position, the glider inflates progressively and after a few steps we are in the air. It is surprising to see how short the take-off run can be considering the size of the wing: only 24 m2, and "reflex" as last name.

Performance
The Hadron, as well as being an outstanding glider in turn and manoeuvrability, is armed with performance in sink rate close to a free flight glider. I was surprised to notice that keeping level flight requires little gas, and that the take-off run was short and I didn't have to run like a madman. As we increase the speed, logically, we must give more gas but still less than what I’m used to; in this sense I had power to spare. This, with a wing of only 24 m2.
I would have liked to try other sizes: a smaller one, perhaps of 20m2 to explore its limits, and one of 28 m2. Maybe a large Hadron would be an "ultimate weapon" for a traditional paramotor Championships, I think the manoeuvrability/speed/performance ratio could be very good – of course, we would have to try it first.

Speeds
Hands-free and with closed trimmers I fly at 39-40 Km/h; with open trimmers I reach the remarkable speed of 52 Km/h. Combining speed-bar and trimmer I achieved a maximum speed of 63 Km/h. Although there are other models that have better top speed, the interesting thing about the Hadron is that you can combine speed-bar and trimmer in different ways to get closed turns at high speeds and fly very fast on the straight sections.

Conclusion
One of the star gliders for the present slalom comps, the Hadron also offers good performance and high speeds to navigate. It is, therefore, a very good option for sportive pilots who like to cruise and play from time to time. If we choose the right size, it can be an interesting glider for traditional competitions.
It is a 'slalom race' paraglider, easy to get you started: it is comfortable and relatively easy to fly at trim speed but requests expert hands to squeeze all its performance flying fast. It is a sensitive and very reactive wing with a totally direct handling. In fast flight it is not a padded or easy glider; its very efficient profiles give back a lot of energy in the turns, which we must use well to exit flying forward and not in useless surgess.
