BAD Call on the transparent stuff ; it's difficult to see
in the air , unless you also include a bright color on
the LE and tips !!
I would NOT enter a thermal with you , and a transparent
sail.

-we are looking into german transparent folien (ORACOVER)+glue

to replace dacron sail!

Span-wise tension on the sail of the Exxtacy, along with
a wide webbing cord on the TE , is how the sweep is
held in place (along with a tensioner on the front of the D-tube)
;
how do you plan to deal with this , when using oracover ?

=my fellow nano trike +ATOS.
I really, "Like", the simplicity of that design ; i imagine, a lot of thought
went into it ? It is a testament to the ingenuity of the designer !!!

Any shots of it flying , ( From the ground ) ; i'd enjoy
looking at how visible it is ?

I Really like the Atos design ; i can't afford it, but will be
content with my Old, ($ 1,200, and used) Exxtacy glider. She may
be Old ; but was built very strong !

I don't recommend tucking.

I also don't suggest flying any unusual maneuver close to the ground.

I'm aware of the tumble maneuvers done by the BKB glider. In fact, in amusement parks rides I much prefer an end over end tumble to a spinning teacup. see Zipper. Zipper (ride)

But I can't suggest tucks, forward or backwards, in any aircraft other than the BKB.

I would love to buy a new Kasper Wing ultralight, so I watch with interest as this classic design is being tested across the pond.

=more info from another pilot...

=iff analysing Witold Kaspers scatch I think, KASPERwing should fly good
withaut rear spar pocket...(ribs=airfoils can be directly connected to the rear spar !?)

BTW=in this case,NO distorsione of upper surface.

The design evolution of the "hang glider" has now reached incredible capability and performance. The European designers like Felix Ruhle (and the others whose names I don't remember) are just genius-caliber people. Being able to have a 22-24 to 1 glider that goes in a giant ski bag on top of your car, that one person sets up in 20 minutes, weighs 80 pounds, that has the level of performance to fly 200-300 miles... is a huge technical achievement. My hat's off to these guys.

And yes dear Henryk, Witold Kasper was absolutely a brilliant designer during the early days of this type of aircraft.

Bille Floyd is right on one important point... anyone who has been in a thermal with a bunch of other gliders will tell you that instant visibility is a life or death matter.
