Gipsy Maior ' As 'n the Gase of the SwaBm"- this machine is of wooden construction, but here the occupants sit in a well-win dowed and adequately soundproofed cabin and the undercarriage is of a re tractable type. The Eagle has the repu tation of being one of the quietest single- eneined machines to be found, and a new model is expected to be produced m which the minor responsibility of under carriage retraction has been eliminated. The specification of the Eagle is as fol lows; Span folded, 14 ft. 10 in.; length, 2(1 ft.; weight empty, 1,450. lb.; disposable load, '950 I''.' maximum speed, 148 m.p.h.; cruising speed, 130 m.p.h.; landing speed, 45 m.p.h.; initial rate of climb, 700 ft.' ruin.; range, 650 miles; price, £1,250.

C.LW. pOKMED in i935 for the purpose of manufacturing machines with a patent type of wing construction, the A new trainer for the new technique : the Pobjoy-engined Curlew monoplane. C. L. W. Co. produced its first machine last year. . This was a tandem-seater low-wing monoplane designed primarily for training, and the production of this machine should shortly be started. The Curlew, as it is known, has been planned largely for the instruction of those pilots who will eventually pass on to the modern type of clean monoplane with a comparatively high wing loading and split flaps. Any engine up to T30 h.p. may be specified for the machine, though the prototype is fitted with a Niagara III. During tests a terminal velocity of 305 m.p.h. was reached with out failure of any kind. The specification of the Curlew is as fol lows: Span, 27 ft.; length, 21 ft. 6 in.; weight empty, 970 lb.; disposable load, 530 lb.; maximum speed, 135 m.p.h. Makers: C.L.W. Aviation Co., Ltd., Gravesend Airport, Kent. c.w. W HILE, on the other side of the Atlantic, there is a definite trend towards the use of stressed-skin con struction, even for smaller types, the C. W. Cygnet is interesting as being the first light machine in this country to be so constructed. By this time the Cygnet should have made its flying tests, and it will be interesting to see how the machine compares in the matter of per formance and payload with the more normal wooden machines. The Cygnet is a* side-b3^-side seater low-wing cabin monoplane for the private owner or club, and is designed to be fully aerobatic. The construc tional methods were described and illus trated in Flight of December 10, 1936, and at that time it was claimed that the wing, with ailerons, flaps and controls, weighed only 2 Ib./sq. ft. The prototype Cygnet Minor is being fitted with a Cirrus engine, but an alter native unit is the Pobjoy Niagara. Later on, work will be started on a small twin-engined monoplane for luxury private ownership. The specification of the Cygnet Minor and the estimated performance figures are as follows: Span, 34 ft. 0 in.; length, 24 ft. i\ in.; weight empty, 850 lb.; disposable load, 600 lb.; maximum speed, 125 m.p.h.; cruising speed, no m.p.h.; landing speed, 35 nup.h.; range, 600 miles; price (pro visional), £795. Makers: C.W. Aircraft, Ltd., Montrose Avenue, Slough Trading Estate, Bucks. . ^,, Chilton B Y the time this issue appears the new Chilton monoplane, which is being built under the guidance of the Hon. A. W. H. Dalrymple and Mr. A. R. Ward, should be flying. This ultra-light machine is a low-wing single-seater monoplane with plywood skin which is at present fitted with a 32 h.p. Garden Ford engine. Great efforts have been made to see that the machine is as clean as possible and, in order to nullify !he inevitable flat approach effect, flaps are being fitted. , The specification and the estimated per formance figures of the Chilton- are as fol low : Span, 24 ft.; length, 18 ft.; weight empty, 380 lb.; disposable load, 250 lb.; 'ned toJ* fl°wn by the novice pilot : the Dart Kitten, at present fitted with a 7 h.p.
