Design and development

The Lo-150 was developed from the 10 m (32.8 ft) wing span aerobatic Vogt Lo-100 as a performance cross country sailplane.[1][2]

The Lo-150 is constructed from wood, including its wooden monocoque fuselage. Its 15 m (49.2 ft) span two-piece wing employs a Clark Y airfoil and incorporates flaps for glidepath control. Early examples use a take-off dolly and land on a fixed skid, while later ones use a fixed monowheel landing gear.[1][2][3]

Fifteen Lo-150s were produced.[1][2]

Operational history

Several Lo-150s were imported into the United States. A.J. Smith won the US Nationals flying an Lo-150 in 1961. Harold Jensen flew an Lo-150 700 km (435 mi) in 1962, winning the Barringer Trophy.[1][2]
