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.
