The SuSi concept has proven over the years to be light, durable, safe and fun. Achieving EN-A ratings at normal loadings for the SuSi 4 opens up new opportunities for teaching as well. So, the SuSi 4 will also replace the Eazy Superlight in AirDesign range. With the certification from A to D depending on the size and wing load it is a great toy for all kind of pilots, same all fun from beginner to expert and pro.

The past 5 years, the Susi 3 was a role model in its class so not only AirDesign kept all the good things like agility, handling, loading options, speed, durability, versatility – but AirDesign have managed to improve it all on the SuSi 4.

SuSi 4 – #Superlight4all

"Going out, where I love the most being, out in the skies over snowcaped mountains. I love it. I love it when he’s taking me there!
– Wake up, little SuSi, he’s telling me, today is the big day. Today is SuSi day, you’ll meet lots of sisters up on the peaks!
Funny coincidence: the radio is playing this cover from Siouxsie & The Banshees – The Passenger I take it as a sign for another great journey with my beloved Passenger!

Well, what shall I report about the hiking and the flying… you already know well about it. Just enjoy the nature and enjoy your flight! That’s my style. When we meet with other couples at the parking lot before the hike, I’m surprised that I have quite some bigger and smaller sisters. And climbing up in the forest, then the fields, this bit of cliffs, we all exchange about life, nature, gliding, thermalling, competitions, speeding, all the fun we have.
And true, sometimes couples can be odd: this light casual pilot with a larger sister, this sporty shapy (mmmmh) pilot with my tiny sister… all sharing a same, same but different fun at the same time, in the same place. Louise just got her licence last month. Flying with SuSi A. Johnny (aaaah, Johnny), the himalayan survival guy, top fit, flying tiny SuSi D. All these other friends enjoying also SuSi B like me, and SuSi C of course.

Time to fly now. Let me enjoy it and I call you later!
The sun sets and turns into shades of orange and finally red. What a cliché, but I love it every time! One last SuSi sister is landing with her passenger. Ron and SuSi B just come back flying a nice triangle cross country style into the flats and back. The smile on Ron’s face reminds everybody else what this simple but amazing day brought us. We all love it, and I love my Passenger!"

How to describe SuSi 4…

…in one word?

…in one image?
All these SuSi passengers being so different and sharing the same fun.

…in one dream?
Taking my passenger on a bike world tour, flying high, mountains, dune soaring, XC and so much more.

What has improved

  • Better starting behavior
  • More stable in full speed
  • More balanced feeling overall
  • EN-A for size 18-26

Construction & features

  • Double coated Skytex, doubled seams and etching tape on edges, new nose guard patches: robustness is the key.
  • Unsheathed Aramid but color-coded lines! Solidity has never been so easy to untangle.
  • Shark nose with un bendable Nitinol rods not only to save weight and increase robustness, but also to help for a more compact folding… To slip it more easily into your tiny rucksack.
  • On the leading edge, ground attachment loops help to prevent the paraglider from slipping on a steep and/or slippery slope (snow).
  • Seamless razor edge with mini ribs: all seams are internal for a cleaner surface.
  • Choice of comfy 12mm aramid or Superlight dyneema risers.
  • New BC riser control system for better control and stability at high speeds.

Designer's notes

“Again, the story repeats. The SUper SImple glider runs into its 4th generation. Development prolonged with tons of innovations like the BC-control and ratings in the EN-A. And still offering its now infamous flying sensation. I am stoked to have been able to redefine this glider and widen the usability of the wing again.
I remember the first generation of the SuSi which had no certification (only load-tested). I built it only for myself because I wanted a wing for hike&fly which should be light, simple but performing.
Today it still offers its typical flying sensations, it’s more robust than ever, and pilots all around the world can rely on the SuSi like they do since so many years!"

-Stephan Stiegler, Designer

Why is SuSi now the Superlight-option for the EAZY?

Actually, the EAZY was built from SuSi. The SuSi concept has been proven over the past years to be safe and funny – so, it was obvious to design the EAZY based on SuSi. On the latest SuSi nothing changed much from perspective of agility, speed and fun but AirDesign closed the gap to the EAZY by certifying it into EN-A – bringing the worlds together!

What’s new?

  • New profile
  • Shark nose with Nitinol rods
  • New riser system with real B-C control
  • Leading Edge Protector Patches
  • Line settings & brake system
  • Internal mini ribs

Not that much of the spirit, but in construction details, a lot!
Improving the SuSi recipe, the glider feels more balanced overall. The starting behaviour is even improved (yes!), rolling is more controlled. Full bar, the canopy has become more stable even with a glider being faster.
It got a fully working BC-riser control system over light or Superlight risers– it’s by the way a matter of weight or comfort which ones you use, it’s up to your choice.
And, in the standard loadings AirDsign still achieved an EN-A rating (on most sizes), so newcomers to the sport can confidently fly the SuSi as their first glider. Surprise, surprise!

How small can it get?

SuSi 3 16 was the smallest EN-B certified glider in the world, now SuSi 4 14 definitely takes the lead (it’s only 12.18m2 projected)! And SuSi 4 18 is certified EN-A… AirDesign is definitely the specialist for small certified gliders. There is always a SuSi your size, whether you want to fly fast and furious, or smooth and peaceful whatever your weight is.

Here are a few examples. Adance's advice: roll it up!

After having created a nice narrow strip, roll it from trailing edge up to leading edge, pushing all the air out. It’s a good way for a small volume pack, but don’t store it this way.

How does the “SuSi trimmers” work?

These trimmers are connected instead of, or in addition to your speed bar. They allow you to lock up an accelerated position, up to 30 to 50% of full accelerator range.

Note that locking the trimmers in accelerated position takes the glider out of the certification. Be aware that your glider’s incidence is making it more sensitive to collapses.

How to do stable big ears with my SuSi?

Thee Susi 4 has 2 low A lines on each side. If you grab high, pull hard, a real big ear will come and bounce onto the lower surface. Not stable. Instead, grab the exterior line just above the maillon, thumb down (palm facing outside). Slowly twist your wrist around the maillon. This generates small stable ears. Now that they are in place, pull down to make them bigger.
