The Valmet L-70 Vinka (Clamp or Cold Wind) is a Finnish three-seat military basic trainer designed in the 1970s. It was used by the Finnish Air Force from 1980 to 2022.


Replacing the FAF's Saab 91 Safir trainers became topical in the late 1960s. An indigenous replacement was desired, and on 15 September 1970 the Ilmailuteollisuuden Kehitysohjelma (IKO, Development program of the aircraft industry), led by Elias Järvineva, was formed to create it. The goal was to revive the Finnish aircraft industry, which had not built military aircraft since the unsuccessful Valmet Tuuli III in 1957.

The aircraft was named the LEKO-70 (Lentokone-70, Airplane-70), and first flew on 1 July 1975. The FAF ordered 30 in January 1977, and the type was given the name Vinka. The first series-produced Vinka made its maiden flight on 29 December 1979, and the type entered service the next year.

An export version called the L-70 Miltrainer was also created in 1980, but not a single one was sold, and thus only one prototype was built. In the 1980s a more advanced version of the Vinka, the L-80 Turbo-Vinha (Turbo Quick) with a turboprop engine and retractable landing gear was created. The L-80 eventually evolved into the L-90 TP Redigo (later known as Aermacchi M-290 RediGo).

Vinkas were the backbone of the Finnish Air Force pilot training from 1980, but they were replaced with second-hand Grob G 115Es in 2020–2022. The Vinka was the last indigenous aircraft type in FAF service.
