Optimal 550
Olle Bergendahl test his model after 40 years of storage


A modern class S2/S-int glider from 1944-45, designed and built by Olle Bergendahl. After having been stored in its box for 40 years, the model was flown by Olle at the 1987 OT-champs. It flew so well that Sigurd Isacson named it "Optimal" (same meaning in Swedish as in English). The plan is based on measurements from the original model.
