Only one 1-29 was built and has subsequently been presented to the National Soaring Museum. It consists of a modified 1-23G fuselage and tail with the addition of a constant chord, laminar-flow airfoil wing and balanced dive brakes. The wing ribs are indentical, made from one master die to help ensure laminar flow. It has flush, counter-sunk rivets, and the heavy, deep spar helps to reduce elastic wing deflections and minimize skin oil-canning.
