The Aermacchi M-290TP Redigo is the Italian-marketed continuation of the Valmet L-90TP Redigo, a turboprop aircraft developed in Finland. The aircraft evolved from the Valmet L-70 Vinka and the L-80; the first prototype, a modified L-80, took flight on February 12, 1985. The type was officially introduced to service on March 7, 1985. Designed as a basic trainer and liaison aircraft, the Redigo features an all-metal, low-wing configuration with retractable tricycle landing gear. Its cabin is designed for side-by-side seating for a student and instructor, with additional space in the rear to accommodate two passengers or a medical stretcher.
Production was handled exclusively by Valmet in Finland between 1985 and 1995. A total of 31 aircraft were built, consisting of two prototypes converted from L-80 airframes and 29 production units. In 1996, the Italian manufacturer Aermacchi purchased the manufacturing rights and renamed the aircraft the M-290TP RediGO. However, no new airframes are documented as having been produced by Aermacchi following this acquisition.
Technically, the aircraft is powered by a single Allison 250-B17F turboprop engine, producing approximately 313 kW (420 shp). This powerplant allows for a cruise speed of 326 km/h at 3,281 meters and a maximum speed (VNE) of 415 km/h. Depending on the configuration, its range is estimated between 1,000 km and 1,405 km, with a service ceiling reaching up to 7,620 meters. For tactical roles, the aircraft is equipped with six under-wing hardpoints capable of carrying up to 800 kg of external stores for light attack or close air support.
Military service was primarily concentrated in three nations. The Finnish Air Force ordered 10 aircraft in January 1989, delivered between 1991 and 1992, and utilized them exclusively for liaison duties across squadrons HävLLv 11, 21, 31, and TuKiLLv. Eritrea acquired six aircraft in 1994 for a training squadron at Asmara, while the Mexican Navy operated between seven and eight aircraft for reconnaissance and interception squadrons at Tapachula and Campeche. In the civil sector, the aircraft has found a niche with military training contractors; Blue Air Training in the United States operates six aircraft under the designation Valmet A-90 Raider, and Top Aces is also listed as a primary user.
