AD Gliders PURE S/M




AD Gliders PURE :

Introduction: AD gliders is a new brand created by designer and world champion Stephan Stieglair with Martin Gostner ,after moving from UP, to create their own dreams and designs.

I have flew almost all Stieglair designs ,from the old series of Kantega’s ,Summit’s,Trango’s,Targa’s…The feeling under those creations are unique, as it is difficult to miss it.

Today the PURE S/M arrived and I am already airborne at 94 all up with an impress 2 +…

Launching: Pulling the A’s the glider rises slowly at first 75 % then a dab on the brake is needed to stop it above my head.

In the air: I was immediately at home under this wing, as the dampened feeling of the UP Trango 3 was there. It seems that the designer succeeded also to insert his famous "shock absorbents" inside this 6.8 aspect ratio wing ! …
Turbulence is sensed but with comfort, giving the pilot enough time to cope with the conditions. Brakes are precise, as I could immediately and under some turbulence put the glider where I want .It is not the most agile EN-D wing, but the brakes and the overall feeling of comfort allowed me to handle it much better, as it doesn’t need too much time to settle above my head in turbulent thermals.

It seems that when pulling a bit on the brakes in turbulent conditions, the glider behave like the time has stopped for a while and stands still for a second, allowing the pilot more time to think how to react under it…
The turns are flat, even with weight shift and brakes. The brake pressure is medium and it reminds me of the Trango 3 .
Inside the thermals the wing really turns toward the core !,and the agility is more pronounced enabling me to turn very tight..I liked that feeling a lot.

Big ears are unstable in turbulence, especially when the accelerator is pulled. I didn’t find them usable for even a good sink rate. Even the 360’s has to be pulled with some G’s to achieve -10 m/s .

Climb rate: At my wing loading the climbs in moderate thermals are still very good .Time is needed to evaluated more versus the competition, which I will but later ,in order to be sure after some more flights with it. But it seemed very good so far among the best.

The trim speed is high and I think around 40 km/h .As for the gliding performance I sensed that it has very good ability in head wind .I will post some videos soon with some recent EN-D wings…

Have to mention also the excellent construction and workmanship ,with nice small details,like the adjustable soft edges brakes.
Nylon rods are inserted in the leading edge ,without the use of Mylars stiffeners,just on the last 8 cells on the sides.
It all you would expect from a super clean and modern EN-D glider .
