Luigi Teichfuss took part in the First International Gliding Competition, held on Monte Sisemol near Asiago in October 1924, with a glider of his own design, the poorly documented Condor.
At the Competition he saw the Akaflieg Darmstadt D-9 Konsul and used it in 1927 as the starting point of his Gabbiano design, though the finished aircraft was distinctly different.
[1][2] The Gabbiano was a high wing cantilever monoplane built from wood and covered with a mixture of plywood and fabric.
The outer panels were straight tapered to blunt tips, the wing becoming thinner and thus acquiring dihedral though retaining a horizontal upper surface.
The fin and fuselage mounted tailplane, both ply covered, had swept, straight leading edges which were rounded at their tips to merge into a curved rudder and semi-elliptical elevators.
