Addyman STG
The Addyman STG was a single seat primary glider, amateur designed and built in the United Kingdom in the mid-1930s.
==Design==
Erik T. W. Addyman designed and built his STG single seat primary glider for low cost basic training. As such, it was a simple, wooden, aerodynamically unrefined aircraft with a relatively low aspect ratio wing, a cockpit nacelle under it and a flat open truss girder fuselage aft. The unswept wing had parallel chord with blunt tips and was built around two spars. There were no flaps or airbrakes. Above the wing landing wires ran from about mid-span on each wing from the spars to the top of a centrally mounted inverted V-strut; below, similarly arranged flying wires ran to the lower nacelle longerons.〔
Attached immediately behind the single open cockpit headrest at the forward wing spar, the nacelle extended rearwards only to the wing trailing edge, suspended from an inverted V pair of struts to the rear spar. A landing skid extended over most of the length of the nacelle. Aft of the nacelle, the fuselage was an uncovered converging Warren girder structure carrying the tail surfaces and braced laterally by wires to the mid-span wing points. The fin was very small but carried an almost rectangular rudder which extended to the fuselage keel via a cut-out in the elevators. The tailplane was straight tapered, with a swept leading edge. A wire tail bumper completed the undercarriage.〔
The STG was built at Harrogate and flew for the first time in June 1934.〔
