Slingsby T3 Dagling (Zogling)

The Zogling primary glider was designed mid twenties by Fritz Stamer and Alexander Lippisch who worked together at the Aeronautical Department of the Rhön-Rossitten Gesellschaft ( RRG).
The first version had an A shape wooden frame that extended to the tail. A variation of the design was developed by Wolf Hirth and consist of 4 steel tubes joining the wing and fuselage to the tail instead of the wooden members. 

Drawings were spread in USA and England where Reginald Dagnall led his company RFD of airship building. He made some alterations of measurements and the glider was renamed “ Dagling” as combination of Dagnall and Zogling. 

The concept of the Dagling is that it could be built by aeronautical companies like Slingsby, students at technical schools, gliding clubs or furniture manufacturers. 

Although basic, it was easy to build and, fortunately, to repair because students pilots often broke it. 

The Dagling was the forerunner of all the others primary gliders like the SG-38 and the SABCA Junior. It gave the first sensations of flight to many aviation dreamers that often founded friendly association to handle it. 

Anorack fact : Alexander Lippisch began his aeronautical career with this very basic design but specialized later in swept-wing and tailless designs like the Messerschmidt Me-163 rocket fighter and the Lippisch P-13 ramjet delta interceptor.
