Development work began in 1970. The first prototype (named LEKO-70) flew for the first time on July 1, 1975. Series production began on January 15, 1977. The L-70 was introduced in 1980 as a replacement for the Saab Safir by the Finnish Air force developed. The Finnish Air Force placed an order with Valmet for 30 aircraft. The first aircraft were delivered in February 1980, the last in 1982. Of the machines delivered, 28 are still in use.

Valmet tried to market the L-70 Vinka internationally under the name L-70 Miltrainer; however, this failed because not a single order was received.

construction

The aircraft is powered by an air-cooled Lycoming AEIO-360-A1B6 boxer engine with a Hartzell two-bladed metal propeller and is designed in a conventional all-metal half-shell configuration with a rigid nose wheel landing gear and as a low-wing aircraft. Students and teachers sit next to each other.

L-80 TP Turbo Vinha

After unsuccessful attempts to establish the L-70 Vinka on the export market, Valmet developed the L-80 TP Turbo Vinha, a turboprop version with retractable landing gear. The prototype ( OH-VBB ) had its maiden flight on February 12, 1985. However, it was destroyed in an accident on April 24, 1985, the pilot Paavo Janhsen and engineer Juhani Jääskeläinen were killed. Equipped with an Allison turbine, the second prototype was called the Valmet L-90 TP and was the starting point for the development of the L-90 RediGo or Redigo (both spellings are common).
