Valmet L-80 Turbo-Vinha

Valmet L-80 TP Turbo-Vinha was a prototype for a new Finnish turboprop basic trainer aircraft. The aircraft, which carried the designation OH-VBB, was destroyed in a crash in 1985, killing the test pilot Paavo Janhunen. The aircraft was a further development of the Valmet L-70 Vinka and would eventually lead to the Valmet L-90 Redigo.

The Allison turboprop engine was used in the second aircraft, the L-90 TP Turbo-Vinha (OH-VTM) which was destroyed during an aerieal display in Belgium. The third of the series (OH-VTP) got the new name Redigo or RediGo (used in sales brochures).
