It was the last Slingsby sailplane to be mostly constructed of wood. The Slingsby Dart was the last of a long line of gliders and sailplanes built by Slingsby Sailplanes Ltd almost entirely from wood. From the Slingsby Skylark 2 of 1953 onwards, the company had used Gaboon ply, thicker but less dense than the traditional birch for surfacing wings and fuselage, as it gave a smoother surface capable of maintaining the more demanding profiles of the newer aerofoils. The Capstan flew ten years later with double curvature parts of the fuselage skin produced from glass-reinforced plastic (G.R.P). Combined, these were the construction methods initially used for the Dart. The Dart was originally a 15 m sailplane, aimed immediately at the 1964 UK Gliding Championships and beyond at the 1965 World Championships. Its wings were shoulder mounted, with 2 dihedral and about 0.75 forward sweep at quarter chord. They were built around spruce spars with a plywood covered torsion box ahead to the leading edge, fabric covered behi...More: http: //booksllc.net/?id=2582595
