JULY 7, 1938. FLIGHT. 23 Two Flight photographs show ing characteristics of the Grumman Gulfhawk (G-22) single-seater. In the lower one the striking markings on the top plane, to convince spec tators that the Gulfhawk really does fly on its back (the re tractable wheels sometimes make this difficult to verify) show up to advantage. Gladiator, the degree of supercharging commonly used for fighters in America being rather lower than that adopted for corresponding British engines. The landing speed is about 65 m.p.h., and the fact that similar machines are used every day from American aircraft carriers is sufficient recommendation of the quali ties at the lower end of the speed range. View is not nearly so bad as might be expected, except directly ahead. Outlook is improved by the '' gulling '' of the centre section and a cut-out on the trailing edge. When the machine is used as a fighter, twin synchron ised Browning guns are installed in the top cowling. Two 100 lb. bombs may be carried under the lower planes. The designation of the type, as used by the U.S. Navy and Marines, is F3F-2. Previously Major Williams operated a Curtiss Goshawk, likewise a Navy fighter. The Grumman machine designed to supersede the F2F-3 is a mid-wing mono plane designated the XF4F-2 and powered with a 1,000 h.p. Pratt and Whitney Twin Wasp two-row radial. It should be good for over 300 m.p.h., and is probably the fastest ship-plane now in existence. Due to the peculiar layout, the pilot is unable to look vertically down except through windows in the floor. iwwiw^lp ' Flight " photographs. ECONOMICAL TRAINER Low-wing Stinson : Perforated Flap : 190 h.p. Lycoming THERE is a very definite market for an economical two-seater trainer for military and civil purposes. The Stinson concern, whose products are distributed in Europe by Brian Allen Aviation, Ltd., of Croydon, have lately added to the somewhat limited range now available by producing what they term a primary-transition trainer. Fitted with the latest type of Lycoming R-530-D2 radial of 190 h.p., this low-wing cantilever monoplane has a top speed of 161 m.p.h., and lands at 58 m.p.h. with the aid of a perforated flap, following the latest American military practice. A variable-pitch airscrew is optional equipment. The fuselage is a welded structure and incorporates two steel bulkheads to protect the occupants in case of a turn-over. Fuel is carried in two tanks beneath the floor. The tandem cockpits have a transparent enclosure. The wing has a semi-stressed skin nose section with trussed duralumin ribs behind. There is a single "I "-section duralumin spar, and stamped duralumin nose ribs. A fixed "trousered " undercarriage is fitted; door and jacks facilitate tyre changing. Hydraulic brakes are fitted as standard equipment. The removable tail surfaces are aerodynamically and statically balanced. Horizontal trim is adjusted by a tab on the elevator. Data are: Span, 30ft.; height, 7ft. 8in.; length, 25ft. 5m.; undercarriage track, 8ft.; wing area, 130 sq. ft.; wing load ing, 15.2 lb./sq. ft.; power loading, 12 lb./h.p.; range, 480 miles; ceiling, 15,000ft. Helicopter Record FLYING the Focke-Wulf helicopter, Herr Bode, chief pilot of the Focke-Achgelis Co., on July 26 flew from near Bremen to Rangsdorf aerodrome, Berlin, a distance of 143 miles. This constitutes a world's distance record for the type and far surpasses the present official record of 67 miles held by Fit. Capt. Frau Hanna Reitsch.
