I am wonder why ARR had bought a version with only 2 engines instead of 3 as was in standard Italian S.79 for whole war (faster, better climbing etc.). So did Yugoslavian, they bought standard version in 1939-40.

ARR had ordered the version with only 2 engines, why?

Budgets cuts?

There are a good number of reasons why the two-engine version was better:
-it was lighter so it could carry a bigger load
-it used less fuel, giving a longer range
-it allwed for a proper bombardier station with a proper bomb sight in the nose plus a 13.2 mm machine gun giving a better frontal defence
-the engines of three-engine version provided 780 HP each while the engines of the two-engined (radial) version provided 1000 HP each - however the increased air resistance/drag caused by the third engine negated the "advantage" of the little extra power and as a result the two-engine version was much more efficient/streamlined
-when the plane was fitted with two 1500 HP Jumo 211 engines, it was way more powerful than the three-engine version in addition to the streamline advantage, and that was when the plane was at its best.
