Some of the largest machines thus far built are of the Caproni Ca.4 type, fitted with three powerful motors, two of which drive tractor propellers while the third is a pusher and is located between the other two. Two cars are fitted and, on some of the trial flights made in this country, a large number of passengers have been taken up at a time. To prevent having to use excessively large control units in the form of single surfaces, these units are subdivided. For example, the rudder consists of three interconnected units. These big machines have a tremendous load-carrying capacity and are used largely for bombing expeditions.
