The Vogt Lo-170 is a West German high-wing, FAI Open Class single seat glider that was designed by Alfred Vogt.

Design and development

The development of the Lo-170 was started in 1960. It was intended as a modern 17 m (55.8 ft) wingspan cross country sailplane for production by Schempp-Hirth.

The forward fuselage was built from welded steel tube, surrounded by a fibreglass skin. The wing was built from plywood in a negative mold and then covered with fibreglass. The wing uses a Wortmann FX 61-184 airfoil.

Schempp-Hirth decided to produce the Schempp-Hirth Standard Austria and its FAI Open Class variant Schempp-Hirth SHK instead and as a result only one Lo-170 was produced.

Operational history

The aircraft was converted to a motor glider in 1972, with two wing-mounted engines. Plans included increasing the span to 20 m (65.6 ft).
