Aerotechnik L-13SL Vivat

01/31/2015. Remarks by Johan Visschedijk: "Aerotechnik of Kunovice, Czechoslovakia, was a small enterprise that undertook overhauls, modifications and minor development and production work for the Czechoslovak Federal Aeroclub, mainly involving Zlín Z 226 Treners and Z 326 Treners, which were overhauled and fitted with new Avia M 137 engines. It also produced aircraft piston engines and hot-air balloons, and marketed kits of the French Pottier P.220S Koala with a 75 hp Aerotechnik Mikron III B engine. In 1993 it was bought by Evector, producer of the EV-97 Eurostar, and in 1996 it merged into Evektor.

In the summer of 1976 Aerotechnik started the design of a two-seat motor glider version of the Let L-13 Blaník sailplane. Designated L-13SW Vivat, this featured side by side seating instead of the tandem layout of the Blanik. It was optimized for both elementary and advanced training, and authorized maneuvers included sharp turns and stalls up to 60°, slips, skids, and unlimited spinning. Construction of three prototypes started in the Autumn of 1977 and the first of these (registered OK-068) made its initial flight on May 10, 1978.

The L-13SW was powered by a 65 hp Aerotechnik Mikron III S engine, later versions were the L-13SDM with a 65 hp Mikron III AE engine, and the L-13SL (later L-13SDL) with a 67 hp Limbach L 2000 EOI engine. Over 160 aircraft were delivered to customers in Belgium, Canada, Czech Republic, Finland, Germany, Slovakia, South Africa, Sweden, Switzerland, the UK and the USA. The Vivat is no longer in production."
