TWIN RS 2 – passionate about
tandem flying
The TWIN RS 2 was developed by a team of
experienced professional tandem pilots. The
goal: To create a fully reliable tool for daily use
that you can rely on 100% from take-off to
landing.
Thanks to RAST, the take-off behavior is very
harmonious and forgiving, so that there is no
stress even in unfavorable conditions and/or
with a hesitant take-off run of the passenger.
The easier take-off behavior through RAST is
most noticeable with nil or tail wind.
Once in the air, the TWIN RS 2 convinces with a
playful and fatigue-free handling as well as
sensational climbing performance even in weak
conditions. In turbulent conditions, RAST
ensures extremely high canopy stability and
increased safety.
The flair characteristics of the TWIN RS 2 are
outstanding and make the soft landing a breeze
even in nil wind.
All these features make the TWIN RS 2 a
reliable partner for relaxed passenger flights.

Air
Section
Technology, known as ‘RAST’ for
short.
This system divides the interior of the paraglider
into several chambers crossways to the flight
direction.
Defined openings regulate the inflowing and
outflowing air in such a way that they can
influence the way the canopy fills (when
launching) and also how it empties (in the event
of canopy stability problems).

Inflation behaviour
RAST slows down the inflowing air when the
paraglider is inflating. The front part of the
profile which is relevant for flow thus takes
shape much more quickly and the glider
immediately begins to rise up from the ground.
The back part of the canopy is filled with air only
slowly during the subsequent stage of inflation,
which results in very harmonious and smooth
launch behaviour without any tendency to
overshoot or launch the pilot unintentionally.
Flight behaviour
It is in turbulent air that RAST really puts its
strengths into play, effectively stabilising the
canopy and gently calming turbulent air.
This makes the TWIN RS 2 extremely stable
and forgiving, which results in noticeably
improved precision and comfort during flight,
