Construction
The UP Guru is the ideal wing for pilots that desire the ability of a high-end competition wing. We
achieve the optimal combination of performance and safety by implementing our completely
overworked profile (NGA – new generation airfoil) with several innovative detailed solutions
Passive safety by
- Different Angle of Attack over the wing span
- NGA provides perfect internal pressure at all angles of attack
- High arc design - very manageable handling and safety
High performance by
- High A/R
- Unsheathed lines
- Long battens
Front Stabilizing System
UP was first with the Aerofoil Stabilising System, an idea that
has since been widely accepted in the industry. The Guru
uses a modified version of the same, and we have chosen to
call this the FSS. Instead of Mylar® the FSS comprises a
Nylon® batten that defines the leading edge curvature and
helps keeping the cell opening open at all times. This Nylon®
batten is insusceptible to bending damage and has no
ageing properties – it will normally outlast the rest of the
canopy by a good margin. This means that the UP Guru will
retain its perfect launching characteristics all through its
service life.
Canopy material
The UP Guru is sewn from polyamide cloth, which is particularly stretch-resistant and durable,
and is specially treated for maximum UV-resistance.
At UP we are always testing new materials to see if our wings can benefit from new developments
in the textile industry. After comprehensive tests we have settled on the following Porcher Marine
material mix for the Guru
 Leading Edge: „Skytex 42 Everlast“ (42 g/m²)
 Top sail front: "Skytex 32 Universal" (32 g/m²),
 Design stripes: "Skytex 38 Universal" (38 g/m²), Skytex 27 classic (27 g/m²)
 Top sail rear/bottom sail: „Skytex 27 Classic“ (27 g/m²)
 Rips, V-tapes: Skytex 40 and 27 Hard (40/27 g/m²)
This mix comprises the best compromise between weight/bulk and longevity.
Line material
The lines used on the UP Guru are unsheathed Dyneema® and Aramid lines made by Edelrid,
Cousin and Liros. Diameters from 0,5 mm to 1,5 mm are employed (brake lines sheeted).
A new manufacturing process in which the lines are pre-stretched makes these lines particularly
stretch- resistant, and they have little or no tendency to shrink. Their break-load is noticeably
