MARCH 12, 1925 3-E-I30 l60tf> LE RHONE 5-E 132 "SOWURHONE 4-E-I3I 135 rP B.M.W. AVIATION IN MEXICO : General arrangement drawings of three military monoplanes recently produced at the Mexican National Aircraft Factory, Valbuena. The 3-E-130 is a single-seater scout; 5-E-132 is a two-seater school machine; 4-E-131 is a two-seater reconnaissance and bombing 'plane. that the leading edge of the centre section slopes inward towards the centre, giving the wings a W-shape in plan. The pilot's and observer's cockpits are located behind the wings, where a good range of vision in all directions is obtained. A Lamblin radiator is mounted on each side of the fuselage. The armament consists of a fixed Vickers gun, firing iorward, and a twin Lewis gun mounted on a scarff ring in the rear cockpit. It will be noticed that the landing chassis in this machine differs from the others. The principal characteristics of the4-E-131 are :— Span .. .. 50 ft. 5 ins. Chord .. .. 19 ft. 7 ins.

ITALY ESTABLISHES 20 NEW WORLD'S RECORDS Rolls-Royce Engines Used ITALY has suddenly jumped into the lime light by establishing in one swoop, or more correctly in two separate flights, no less than 20 new world's records. The machine used in the flights was a Dornier " Wai " twin-engined flying-boat, built under licence in Italy by the S.A.I. Costruzioni Meccaniche di Marina di Pisa, and engined with two Rolls-Royce " Eagles." The machine has been illustrated in fligKtTancris^an all-metal flying-boat monoplane, with the two engines placed in tandem above the wing, one driving a tractor and one a pusher screw. Thus in case of one engine stopping the centre of thrust is not altered, and it is claimed that the machine will carry on with but one engine running. In the record flights the " Wai " was piloted by the Italian aviator Guido Guidi, who had with him as second pilot Herr Richard Wagner, a German pilot, and an engineer. In the first flight the machine carried a useful load (i.e., as sand ballast) of 1,500 kgs. (3,300 lbs.), and established the following record performances: Speed over 100 km., 173 -38 km./h. (108 m.p.h.) ; over 200 km., 172 §3 ktft./h (107-5 m.p.h.) ; over 500 km., 171-00 km./h. (106± m.p.h.). Total distance with 1,500 kg. load, 507-38 km. (315 miles). Total duration, 3 hours 33 mins. 35 sees. Altitude, 3,682 metres (12,100 ft.). With a useful load of 2,000 kgs. (4,400 lbs), the following performances were put up: Speed over 100 km., 171 -954 km./h. (107 m.p.h.); speed over 200 km.. 170-622 km./h. (106 m.p.h.). Total distance, 253-69 km. (158 miles). Altitude, 3,006 metres (9,850 ft.). The speeds with smaller loads were also far ahead of previous records, so that Italy in the same flights gathered in several of the smaller fry. The net result is that the United States have lost 9 records, France 3, Denmark 3, and Italy has established 5 new ones. It is gratifying to note that British engines made the flight possible, bat the records ought to have been established by a British machine. Incidentally, it is somewhat humorous' to reflect that, although the records are recognised as Italian, the machine was virtually German, the engines British, and one of the pilots a German.
