Technical description: |
|
Performance, agility, stability and high climbing performance
were our goals when designing this performance glider. The Envy
was made for experienced cross country pilots looking for
relaxed flying.
The slim elliptical form of the canopy has an aspect ratio of
5.71. The Envy has 56 cells with full diagonals. Lines are
attached to every third rib and this construction allows the
lines to be reduced to two tiers.
The glider is undemanding and resistant to collapse even in
rough air. It features excellent stability throughout the full
weight and speed range. The moderate brake pressure allows
pleasant turns with good climbing performance and increases
progressively toward the end of its travel to offer safety
reserves. The canopy is moderately damped in all axes and offers
flexibility and agility in turns. It does not overshoot or sit
back.
In an induced collapse the glider does not rotate quickly and
will usually reopen within 60 degrees. The opening is smooth and
predictable. Easy launch and landing characteristics are a must.
The use of high-quality materials and constant quality
control during our own MAC PARA manufacturing process together
with consistent development work produces high quality products.
We are proud of them. |
