Design and development
During the 1920s Alexander Lippisch designed a training glider with very low performance to introduce pilots gradually to full-blown gliding. The result was a glider with a very simple structure of an open framework fuselage, with short wings attached by cables to a king post and the base of the fuselage. Lippisch's original design, the Zögling (Pupil in English) had an all-wood fuselage but Wolf Hirth instigated a redesign of the fuselage using steel tubes.
History
The plans for the modified Zögling made their way via the USA to the London Gliding Club and Reginald Foster Dagnall, whose RFD company put it into production as the RFD Primary. They built at least 27. The type became known as the Dagling, a name formed by combining Dagball and Zögling and which became used to cover all types of Primary gliders. In 1933 Fred Slingsby took over construction. Production continued up to the outbreak of World War II. The Primary should not be confused with the T.38 Grasshopper which was produced for the Air Training Corps in the 1950s.
