All these features make the TWIN RS 2 a reliable partner for relaxed passenger flights.

RAST

The TWIN RS 2 features Swing’s unique Ram 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).

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.

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,
