The Valmet L-70 Vinka (Finnish: "Blast") is a Finnish-designed piston-powered military basic trainer aircraft. Design work was begun in 1970 as a replacement for the Saab Safirs then in use with the Finnish Air Force and the first prototype (designated LEKO-70) flew for the first time on July 1, 1975.
The aircraft entered service in 1980 with the last planes of the series of 30 manufactured were delivered from the Kuorevesi plant of Valmet Oy in 1982.
Valmet attempted to market the type internationally under the name L-70 Miltrainer, but no orders followed.

[edit] L-80 TP Turbo Vinka
After unsuccessfully having tried to market the L-70 Vinka for the export market as the L-70 Miltrainer, Valmet developed a turboprop version with retractable undercarriage, which was given the designation L-80 TP Turbo Vinka. The prototype (OH-VBB) made its first flight on February 12, 1985, piloted by Paavo Janhunen. The prototype was destroyed in an accident on April 24, killing the pilot. Equipped with an Allison turbine engine, the second prototype was baptized Valmet L-90 TP and was used for the development of the L-90 Redigo or RediGo (Both spelling versions are found in the brochures from the manufacturer).
