The first of the series of Slingsby Skylark sailplanes was conceived as a small low cost aircraft based on the earlier Prefect.
It was a small aircraft with a wingspan of 13.68 metres and to provide good performance a wing using the then fairly new NACA laminar flow aerofoil sections was employed.
The first of the Skylarks flew in 1953 and showed a respectable performance, but there was obvious room for improvement and development which led to the Skylarks 2, 3 and 4. These were very different and more sophisticated designs.
This West Wings semi-scale model is 1828 mm (72”) wingspan and is intended for radio controlled slope soaring, but prototypes have been bungee launched from flat field sites into strong thermals.
Controls are rudder, elevator and ailerons. The ailerons require micro servo’s built into the wings.
