The Blanik L-13 is an all metal production two-seater, widely used in 36 countries over the world. In Russia (in those days) alone, more than 1200 were delivered. It had a measured performance that was very good for its moderate span and had a relatively roomy fuselage.
The Blanik L13 series began production in 1956. Many were produced and are still to be see around many of the flying clubs. This is mainly due to its solid metal construction, which required little care.
It was a very good performer and held many records, at its time. Untiil 1970 records flown with this outstanding design were kept on the record board. The Blanik L13 is a fully aerobatic glider with a max loading. of 400kg
Its fuselage was made in two half shells and than riveted together. The wings were attached by two vertical pins on both sides of the fuselage. The elevator is also of full metal and of hinged construction. Only one pin locks the two elevator halves under the tail cone which helps to store the plane. The moving parts like the ailerons, Fowler flaps, rudder and elevator are fabric covered. The airbrakes are on top and bottom, with the bottom slightly shorter in length.
