Technical description: |
|
The market is full of "simply designed" mountaineering gliders
and we guess some of them are really boring and slow to launch.
We decided to combine a higher performance wing with a light
weight glider. Pilots who are looking for the lightest
performance intermediate can save a lot of money this way.
Thanks to the excellent reports from Eden 3 pilots we decided
to use the same canopy design and a similar line construction to
the Eden 3. The Velvia has 52 cells, which get thinner closer to
the wing tip. The slim elliptical form of the canopy has an
aspect ratio of 5.26. Diagonal V-tapes and a system of
load-bearing lines give the canopy stability and influence easy
behaviour during extreme manoeuvres. The canopy is very
resistant to collapse. It features excellent stability
throughout the full weight and speed range. In an induced
collapse the glider does not rotate quickly and will usually
reopen within 50 degrees. The opening is smooth and predictable.
Easy launch and landing characteristics are a must. Despite high
performance potential and agile handling the Velvia has good
dampening in all axes. The light brake pressure allows pleasant
turns during long thermal flights, but increases progressively
toward the end of its travel to offer safety reserves.
The Velvia is equipped with light Dynema risers. The lines
are connected to the risers by loops to save weight. Just one
small circular maillon is used in the accelerator system.
The use of high-quality materials and constant quality
control during our own MAC PARA manufacturing process together
with consistent development work on our computer programme PG
produces high quality products. We are proud of them.
