Vivat L-13 versions SW/SL/SEH/SDL

Noël Rumers

The Vivat is very obviously a further development of the famous Let Blanik L13 two-seater training glider, of which about 3000 have been built. The Vivat however has its seats side by side, whilst the Blanik has tandem seats.

The Vivat, like the Blanik, is an all metal construction. The fuselage forward area has steel tube construction. This extends from the engine compartment to behind the wing trailing edge. The tail boom, together with the rudder and elevator are similar to that of the Blanik. The forward steel tubing part of the fuselage is covered with fibreglass, top and bottom. A two part engine cowl top and bottom is used to cover the SL version whilst the SW has a metal/fibreglass cowl. The canopy slides backwards over the top fuselage cover. The front and rear part of the fuselage are riveted together like the Blanik. The undercarriage is retractable on the SW and SL version. The tail wheel is stearable and fixed to the tail plane.

Two engines were built for in this motor glider, the Walter Mikron 65 hp and the Limbach. About 164 units of varios models were manufactured and production stopped in the mid 1990’s.
