Project light aircraft model Aerotecnica AC-12 became established Spanish aircraft manufacturers in the first half 50-ies of the last century. According to design plans, the helicopter was to be exclusively civilian aircraft, but, ultimately, the helicopter was operated only for military purposes, which was due to lack of interest in the model helicopter to private potential customers.
Helicopter Aerotecnica AC-12 has a simple but robust design that provides high aircraft maneuverability, thus, the very aircraft can be equipped with both an open and a closed cabin, which to some extent can increase the scope of applicability of the aircraft.

Its first test flight of the helicopter model Aerotecnica AC-12 has made in July 1954 years, however, due to the fact that the aircraft was not able to successfully complete the test in a short time was created a second prototype, which has a higher stabilization performance during flight, and it is through this kind of improvements, the aircraft finally fully passed its testing stage.
Despite the fairly high draft prospects, helicopter Aerotecnica AC-12 only interested in the Spanish Air Force, which took over operation 10 aircrafts of this model, performing mainly the role of aircraft patrol or surveillance equipment from the air.
Due to ease of construction, the helicopter Aerotecnica AC-12 expended little fuel, while the speed and maximum flight distance performance from him are very acceptable and comparable with current figures of light aircrafts of this class.
The cabin Aerotecnica AC-12 aircraft can accommodate up to two people - a pilot and a passenger, and because of the rather limited space inside the aircraft of this model, transportation on board the helicopter Aerotecnica AC-12 any goods is not possible.

For all the time of issue, the Spanish aircraft manufacturer «Aerotecnica» was built 12 aircrafts Aerotecnica AC-12 models, including two prototypes and manufacturing options 10 aircraft.
