LET L-13 Blanik
Although out of production for a number of years, the Blanik remains one of the most active two-place training and club aircraft throughout the world. An all-metal flush riveted sailplane with fabric covered control surfaces, the Blanik is stressed for aerobatics and has held many two-place records. It is equipped with DFS type airbrakes and Fowler-type flaps. The main wheel has an oleo strut shock absorber and is partially retractable. The horizontal tail surfaces fold up parallel to the fin for transportation and storage.
