The Skylark 2, which first flew in 1953, has a three piece wing with top and bottom surface Schempp-Hirth type airbrakes for approach control.
The Skylark was developed from the 14.63 m. span Skylark 2, requiring an increase of the tail volume and strengtening of the wing spar. Rudi Hossinger of Argentina won the Open Class at the 1960 World Championships at Koln-Butzwelerhof, Germany in a Skylark 3. Many different sub- types, from the 3A to the 3G, were…
The Swallow is a small single-seater which first flew in 1957 designed as a follow on single- place sailplane after the student had completed basic two-place instrucion. It has a fixed wheel and a nose skid, and the leading edge of the wing is covered with thick low-density plywood to maintain a smooth contour. It…
The E model superseded the 1-26D in 1971, being the last refinement in the 1-26 series with an all metal monocoque fuselage which appreciably increased the empty weight. Despite this, Dick Johnson’s flight test show little difference between the earlier models and the E. The U.S. Air Force Academy operates 3 as the TG-3. ATC
All model of the 1-26 make it the most numerous sailplane type in the U.S. today. The 1-26 has, since its first flight in 1954, become the most popular one-design sailplane in the world. Nurtured by the 1-26 Association, an affiliate of the Soaring Society of America, the design provides a significant percentage of the…
The 1-24 was a spare-time cooperative project between Schweizer and Burr when he worked for the company. It features a shoulder wing and an internal traveling balance weight for trimming hands-off at 80 kph/ 43 kt/ 50 mph through 129 kph/ 70 kt/ 80 mph
The ‘standard’ 1-23 introduced in 1948, and with its later versions, the B, C, D, E,F,G,H was for years America’s most numerous performance sailplane. The 1-23B & C were built for the 1952 World Championships held at Madrid – Cuatro Vientos, Spain flown by Paul MacCready and Paul Schweizer. They both had the wing spars…
Built in 1947, the 1-21 won the Nationals that year flown by Dick Comey, whose 483 km./ 300 miles flight was a National distance record at the time. There was no market at the 1947 price so a simpler model, the 1-23, was produced instead. Stan Smith flew a 1-21 in the 1952 World Championships…
The SGM 2-37 self-launching motorglider, which first flew in 1982, has the capacity to operate as a towplane for other gliders. 9 (known as the TG-7A) are operated as trainers at the U.S. Air Force Academy. The aircraft is without flaps but has balanced upper/lower surface dive brakes. ATC
Only one 1-29 was built and has subsequently been presented to the National Soaring Museum. It consists of a modified 1-23G fuselage and tail with the addition of a constant chord, laminar-flow airfoil wing and balanced dive brakes. The wing ribs are indentical, made from one master die to help ensure laminar flow. It has…
