VELVIA VELVIA
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.
