OCTOBER 22. 1925 7, Italy. In all probability some of the machines competingin the race will attempt, the next day, to establish new world's records over the 3 km.-course, which is parallel to theBay front, and which should really give an indication of the actual top speed, of which the machines are capable. Theflights over this 3 km.-course have, of course, nothing to do with the Schneider cup race, but will be purely for officiallyobserved record attempts. THE MACHINES Although, at the moment, complete particulars of the various competing machines are not available, a certain amount of general information can be given and may probably be of interest. The American defenders are Curtiss-Navy racers fitted with the new Curtiss V.I,400 engines. The machines are somewhat similar to those taking part in thePulitzer Race, which was won by Lieut. Cyrus Bettis at a speed of 248-99 m.p.h., and practically the only alterationwill consist in substituting floats for the wheel undercarriage. The machines, which are known as the type R.3.C.2, and oneof which, in the Pulitzer Race, proved somewhat slower than the winning Army-Curtiss, its average speed round thePulitzer course being 241-71 m.p.h., were designed and built by the Curtiss Aeroplane and Motor Company, Inc., of GardenCity, N.Y. The V.1400 engines are the modern and improved versions of the type D.12 engines with which the Americanracers were fitted in the 1923 Schneider Cup Race at Cowes. It is believed that the engine has been somewhat lightened,while at the same time the power has been increased to rather more than 600 h.p. The machines are biplanes of, approxi- THE SCHNEIDER CUP RACE : These two side views of the British challengers, the Gloster-Napier III and the Supermarine-Napier S.4, enable a comparison to be made between the two machines. Both are, of course, fitted with Napier racing engines. The Supermarine-Napier S.4 holds the world's speed record for seaplanes with 226-752 m.p.h. 689
