Ambrosini SAI.107 / SAI.207
The Ambrosini SAI.207 was a light fighter interceptor built entirely from wood and developed in Italy during World War II.
Powered by a single 750 hp Isotta Fraschini Delta, the SAI.207 enjoyed limited success during evaluation of the 12 pre-production aircraft.
The SAI.207 was a single seat, low wing monoplane with a conventional tailwheel undercarriage, developed from the Ambrosini SAI.7.
Its lightweight wooden construction, combined with a 560 kW (751 hp) Isotta-Fraschini Delta R.C.40 inverted-V engine, with a centreline cooling air intake, provided speed and agility.
Armament consisted of two fuselage-mounted 12.7 mm (0.500 in) Breda-SAFAT machine guns.
In level flight the performance of the SAI.207 was impressive.
It achieved a speed of 580 km/h (360 mph) and over 800 km/h (497 mph) in a dive.
The Ministero dell’Aeronautica soon placed a production order for 2,000 machines, plus a pre-production batch of 12 aircraft for operational testing.
After the mixed results of operational evaluation and the signing of the Armistice, no production aircraft were built.
