Valmet L-90TP RediGO
Derived from the earlier Valmet L.70, through an intermediate design known as the L.80TP, the Valmet L.90TP completed its maiden flight in June 1986. The Redigo differed from the L.70 primarily in having an Allison 250-B17D turboprop power plant, a new, increased-span wing, and a retractable undercarriage. The wing is NACA 63-218(mod B3) at the root and NACA 63-412(mod B3) at the tip. The L.90TP is designed to take student pilots through the first 100 hours of training, for graduation directly on to a suitable advanced trainer. Six underwing hardpoints can carry a total of 800kg of stores.
In 1996 Aermacchi took over L-90TP RediGO from Valmet of Finland and redesignated it the M-290TP RediGO.
