With the new 18m wingspan Antares 18S, Lange Flugzeugbau offers a very strong contender for the 18m class. All relevant parameters have been fine tuned for fast cross country flying.

The aircraft has been designed uncompromisingly for 18m wingspan, resulting in a perfectly balanced aerodynamic design with a novel wing outline. Aerodynamically, this wing represents the state of the art for 18m wings, achieveing the lowest induced drag which is theoretically possible.

The two level water ballast system with separate wing and trim tanks allows for wing loadings up to 54.7 kg/m² (11.2 lb/ft² ), currently the highest value found in the 18m class. Even fully loaded does the Antares 18S climb well in narrow and turbulent thermal bubbles.

The full span flaperons have been equipped with an extra negative flap setting (-3°), which has been designed especially for speeds beyond 200 km/h (108 knots).

These factors together with the high aspect ratio elliptical wing geometry of the Antares 18S/T allow for superior glide speeds at lower sink rates than have ever been achieved in the 18m class.
