Hirth LO-150

 

Hirth-LO-150

 

A development of the 10m straight wing LO-100 aerobatic glider, the LO-150 features a two- piece, plywood covered, single spar wing and uses flaps for glidepath control. Designed by Alfred Vogt, the fuselage is a wooden monocoque with a cantilever tail. Early models had a skid and jettisonable dolly instead of a fixed main wheel. A.J. Smith won the 1961 Nationals in a LO-150 and Harold Jensen flew another 700 km/ 435 miles to win the 1962 Barringer Trophy.
