Soaring offers a sense of adventure that uniquely connects a pilot to the environment in a way that’s both relaxing and challenging. Modern composite glider designs are both incredibly efficient and capable of amazing speed, enabling the pilot to conquer conditions as vast as there are sites to soar. Just one such marvel of aerospace technology is the Alexander Schleicher GmbH & Co. ASW 20 sailplane. Designed by Gerhard Waibel, it’s a 15-meter ship that’s proven successful as a trainer and in competition at the World Championship levels.
The Hangar 9® ASW 20 4.7m ARF is a model tribute to the single-seat sailplane. Its dramatic wingspan puts it above the 1/3-scale category; however its light weight allows options not typically found in a giant-scale glider. The sleek fuselage is molded fiberglass right up to the vertical fin for a contoured appearance that’s as elegant as the original. Solid carbon-fiber rods support the foam-core wing panels, while balsa sheeting and carbon-fiber spar caps help assure that the HQ 12% airfoil is accurate and rigid. To complement the brilliant painted finish of the fuselage, the wings and horizontal stabilizer are covered in genuine Hangar 9 UltraCote® film.
As you might expect from a model of this caliber, a scale electric retract and electric spoilers are available. The flaps are functional and the horizontal stabilizer is removable just like the full-size. There are even pockets located in the wings for electric spoilers. But the option that takes this masterpiece of soaring to another level is the practical application of an electric motor system. The specially-made spinner (available separately) fits the contour of the nose so that the motor-drive is practically invisible during flight. As a result, the ASW 20 4.7m is a great way to join the world of RC Aero Tow flying as well as a giant-scale electric powered dream machine.
If adding the thrill of giant scale soaring is the way you’d like to climb higher, add the Hangar 9 ASW 20 4.7m ARF to your fleet now.

The ASW 20 is an FAI 15 metre Class glider designed by Gerhard Waibel and built by Alexander Schleicher GmbH & Co. Its fuselage is nearly identical to that of the ASW 19, mated to newly designed flapped wings for the 15 metre Class. The prototype first flew in 1977. It proved to be a highly successful glider, winning several World Championships, and was still being flown at this level up to 1995. Developments along its production life included winglets, pneumatic turbulators, and wingtip extensions. It remained in production until 1990, when it was superseded by the ASW 27. 765 were built by Schleicher and a further 140 were made under license by Centrair in France.
The ASW 20 was successful in competition, winning numerous world and national championships. Dick Johnson reported that the ASW 20 was the first 15 m glider to demonstrate a measured L/D in excess of 40:1. Roy McMaster, Karl Striedieck and John Seymour won jointly, with others, the world triangle distance record of 1,435 km (892 mi) in 1994 in an ASW 20B. ASW 20s won second and third places in the 15 metre Class at the 1983 World Championships at Hobbs, New Mexico.
