Design and development

Sands developed his replica 1929-style primary glider from the original designs of that era. He promotes it as "much safer than hang gliders or ultralights... [an] excellent project for school or clubs". [1]

The aircraft is made from wood, tube and doped aircraft fabric. Its 32 ft (9.8 m) span wing is cable-braced from a king post and employs a Clark Y airfoil. Like all primary gliders the cockpit is just a seat mounted on the keel with no windshield fitted. The landing gear is a fixed skid, fitted to the underside of the keel. The aircraft is designed to be bungee launched from a slope or auto-towed. The aircraft can be disassembled for storage or ground transportation. [1] [2] [5] [6]

Sands estimates that construction takes 200 hours. In 2011 plans cost US$40 and included two 24" by 36" (60 X 90 cm) sheets, a materials list and "Safety Tips". In 2015 the available Wicks five part kit totaled US$7644.14. [1] [2] [4]

Variants

Plans for a steel tube fuselage version are also available. [1] [2]
