The Sands Replica 1929 Primary Glider is an American high-wing, wire-braced single-seat, primary glider that was designed by Ron Sands Sr for amateur construction, with kits supplied by Wicks Aircraft Supply.
He promotes it as "much safer than hang gliders or ultralights... [an] excellent project for school or clubs".
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.
In 2011 plans cost US$40 and included two 24" by 36" (60 X 90 cm) sheets, a materials list and "Safety Tips".
