 The almost all-metal A-11 was Antonov's first non-wood framed sailplane.It is a cantilever mid-wing monoplane, with straight tapered wings mostly swept on the trailing edge and set with 1.5° of dihedral but no washout.A single spar with a metal-skinned leading edge forward of it and fabric covering aft forms most of the span but the curved tips are supported by twin spars.
