Airdesign Susi 4 Betriebshandbuch Seite 43

A new airfoil and further improvements in the design let the performance – matching even
many EN-B wings.
Depending on the loading and the size the SuSi 4 can accelerate more than 20 km/h when
using the speed-bar, resulting in a maximum top-speed of almost 70 km/h (on smallest size
with top load).
Risers
Like the whole glider as well the risers are optimized for low-weight. They are coming in two
riser-style versions: either a Dyneema-rope style as an option, or as standard delivery we offer
you a more solid sheathed 12mm Aramid riser – it simplifies the handling on ground.
