The Oldershaw O-2, officially registered as the Oldershaw Jana-Linn O-2, is an American high-wing, single seat, V-tailed glider that was designed and built by Vernon Oldershaw.^[1]^[2]^[3]

Design and development

The O-2 was designed by Oldershaw to compete with Dick Johnson's Ross-Johnson RJ-5.^[1]^[2]

The O-2 is constructed of wood. Its {{convert|49.2|ft|m|0|abbr=on}} span wing employs a NACA 63 (3)-618 airfoil at the wing root, with a NACA 63 (2)-615 at the wing tip. The wing is equipped with dive brakes. The landing gear is a retractable monowheel.^[1]^[2]^[4]

Only one O-2 was built.^[1]^[2]

Operational history

The O-2 first flew in 1961 and was flown by Oldershaw in the 1962 and 1962 US Nationals. The aircraft has made a number of flights in excess of {{convert|200|mi|km|0|abbr=on}}, including one of {{convert|294.6|mi|km|1|abbr=on}}. Oldershaw later sold the aircraft to Don Gaede of Torrance, California and it was reportedly still being actively flown in the 1980s. Gaede remodeled the cockpit and introduced a new nose shape. The O-2 was later donated to the US Southwest Soaring Museum, where it is on display.^[1]^[2]^[3]^[5]
