JANUARY 24, 1918. FROM OTHER LANDS. THE ITALIAN «• MACCHI" FIGHTING FLYING BOAT. THE Macchi single-seater fighting aeroplane is one of the most efficient flying boats ever built. Owing to the fineness of its construction, its light weight, and high-powered motor, it is able to ascend to an altitude of 13,000 ft. in only 18 minutes. In a single-seater fighting machine quick climb is, of course, one of the most important essentials of per- the machine weighs 1,510 lbs. When fully loaded to its gross weight of 2,060 lbs., the military weight is distributed as follows • Petrol and lubricating oil, 265 lbs.; pilot, 175 lbs • two Fiat machine guns, both firing forward, no lbs. Total weight of useful load carried, 550 lbs. Near the sur- face of the water the machine can travel at a rate of 112 The Italian " Macchi From -Aerial Age" U.S.A.). flying boat, equipped with a 200 h.p. engine. formance, although this adaptability to climbing rapidly isnot generally associated with machines of the flying boat class. Head resistance has been reduced to a minimum, especiallyin regard to interplane bracing. The struts and interplane bracing is similar in principle to that employed in the FrenchNieuport scout—the single pair of V-struts, the narrow lower plane, and the outline of the planes themselves bear a resem-blance to the Nieuport. The Macchi is provided with steel m.p.h. In the first four minutes it can climb to 3,250 ft. ; eight minutes, 6,500 ft. twelve and one half minutes, 10,000 ft. Sufficient petrol and oil is carried for an air endurance of three hours. The Isotta-Fraschini engine, with which the Macchi boat is equipped, is known as the V4B. This is a six-cylinder vertical type with nominal h.p. of 150 and a bench-test normal h.p. of 190 at 1,400 r.p.m. Bore, 5.2 ins; stroke, 7.1 ins.
