Slingsby T45 Shallow
The Slingsby Swallow was a wooden-framed aircraft, covered in a mixture of plywood and fabric. Its high mounted, cantilever, straight-tapered and square-tipped wing had 3.3° dihedral.
It was Gaboon plywood-skinned and built around a single spruce spar, with a leading-edge torsion box. Its unbalanced ailerons were fabric covered; there were no flaps but dive brakes could be extended in pairs above and below the wings.
The prototype had a 12 m span wing, but all production aircraft had their performance enhanced by an extension to 13.05 m.
