The Slingsby T.41 Skylark 2 was a sailplane produced from 1953 at Kirbymoorside, Yorkshire by Slingsby Sailplanes ==Design and development== Following the technical success of the T.37 Skylark, the concept was expanded with the introduction of the T.41 Skylark 2. The use of laminar-flow sections was continued but the section at the tips was changed to NACA4415 to reduce the tendency to tip-stall. The Skylark 2 was very similar in shape to its predecessor but had a smooth-skinned rounded fuselage and a wing of greater span and area. Composite materials were introduced in the Skylark 2, with the nose cone, wingtips and various small fairings made from polyester resin glassfibre. The thickness of the aerofoils was increased to ensure that drag was reduced over a wider speed range allowing the Skylark 2 to climb faster in thermals at low speed and race between thermals at high speed.
