The Slingsby T.3 Primary (a.k.a. Dagling) was a single-seat training glider produced in the 1930s by Fred Slingsby in Kirbymoorside, Yorkshire.
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 had an all-wood fuselage and was called "Zögling", 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 Mr. R.F. Dagnall and the RFD company. Production by RFD lasted until 1931, and in 1933 Fred Slingsby took over building the "Dagling". Production continued up to the outbreak of WWII. The Primary should not be confused with the T.38 Grasshopper which was produced for the Air Training Corps in the 1950s.
