The ASG 29 has plain flaps and winglets.The structure is a complex composite of carbon, aramid and polyethylene fibre reinforced plastic. This permits a light structure with the strength to carry up to 170 liters (322 pounds) of water ballast, thus permitting the widest possible range of wing loadings for weak and strong soaring weather.
A Schleicher ASG 29 glider shows its monowheel landing gear. A variation of the taildragger layout is the monowheel landing gear. To minimize drag, many modern gliders have a single wheel, retractable or fixed, centered under the fuselage, which is referred to as monowheel gear or monowheel landing gear.
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
The SGS 2-33, indicating Schweizer Glider, Sailplane, 2 Seats, Model 33, was designed by Ernest Schweizer. The aircraft was a derivative of the 2-22, which in turn was based on the SGU 1-7 single place glider of 1937. The 2-33 retained the 2-22 and 1-7's metal wing, single spar and single strut arrangement. [1] [2] [5]
The glider has little tendency to enter a spin. In order to make spinning possible for training purposes or demonstrations a spin kit is available from the manufacturer. It consists of ballast discs applied to the tail to change the center of gravity according to the weight of the crew.

The company was founded in 1927 by Alexander Schleicher using money that he had won as a pilot in a gliding competition. It grew quickly in size and fame, producing many notable designs including the Anfänger ("Beginner"), Zögling ("Student"), Professor, Mannheim, and the Stadt Frankfurt (City of Frankfurt).
The introduction of the ASG 29 gave the ASW 27 a stablemate that can compete in the same class, although the 29 is intended to fly primarily with an 18-metre span and can be motorised. Because of the overlap with the ASG 29 , production of the ASW27 has now ceased.
