Its characteristics were:
The low wing was not satisfactory for an observation aircraft, despite the generous flaps, which gave good STOL capabilities. First flown in June 1940, a year later it was sent to Guidonia where it performed poorly in evaluation. This was MM.11586, the only example produced, as the initial batch of six was never completed.
Another project was the Caproni GDL, also never completed, even as prototype. It should have been capable of 315 km range, 800 km endurance, and its dimensions were 13.8 m wingspan, 10.35 m length, 4.03 m height, 21 m² wing area, with empty weight of 730 kg and fully loaded of 1,010 kg. The engine was the same Hirth HM.508D as the others.
Other STOL aircraft
The AVIS C.4 should have been the winner of the contest, as originally it was meant for the industries involved, but despite being capable 240 km/h, it had poor flying performance.Its characteristics were:
- Length: 8.7 m
- Wingspan: 13.96 m
- Height: 3 m
- Wing surface: 28 m²
- Speed: 240 km/h, min 60
- Endurance: 800 km, 360 range
- Weights: 836 kg/1,329 kg
- Engine: 1 Hirth HM.508D, 280 hp
