1936 - 1006.PDF
APRIL 23, 1936. FLIGHT. 421 MONOSPAR T 4ST year's S.T.25 was produced in its standard \J form with full day- and night-flying equipment well as a radio homing and receiving set. This year the saint' principle has been expanded to provide five separate types for different purposes, in each of which the equipment has been standardised to suit these five purposes. . The new De Luxe model may be taken as typical oi the range, since it incorporates most of the features which are found on the 1936 machines, such as trimming tabs, electric engine starters and a redesigned dashboard lavout in which the R.T.E. homing receiver is within fa'sv reach of the pilo"t, and all the electrical switchgear is mounted on a single panel or box. Structurally, the S.T. 25 remains unaltered, and it will be remem bered that this is all metal and involves the well-known Monospar system of construction, by which the struc ture weight can be kept down to a minimum. The trimming tabs on the elevator and rudder are operated by small and convenient levers which require no effort, and the whole business of. flying the new Monospar is reduced to one of mere flying judgment. Its characteristics are interesting and soon mastered, and the pilot, in particular, has a very excellent, and consequently safe, field of view. In common with most low-uing machines, it is possible to adjust the approach by increasing or decreasing the gliding speed, and really short approaches can be made by a pilot who is thoroughly accustomed to the machine. Once it is firmly on the ground the Palmer brakes can be applied to their fullest extent without risk of nosing over, and full control is retained right down to the stall, which is harmless enough if the rudder is not maltreated. In Europe, paricularly, the radio homing equipment would be very useful and, even if this cannot be used in this country on every flight, there is always the regular and valuable Air Ministry meteorological broad cast from Borough Hill to be received. The electrical equip ment of the Monospar, incidentally, includes landing and navigation lights, instrument and cabin lighting, as well as electric starters on certain models, as already mentioned. The General Aircraft Company have specialised in the pro duction of carefully worked-out running-cost schedules for the There is plenty of light in the Mono spar cabin and the machine can be flown from either of the two front seats. When used as a four-seater that in the foreground folds away, leaving a wide shelf for luggage which can be reached, if desired, through a separate door. The De Luxe model is shown in the air on the left. benefit of air-line operators and others who are interested in the Monospar as a dividend-earning machine. A series of these have been published in book let form. Incidentally, the company has evolved an economical hire scheme which includes the services of a " B " licence pilot. The specification of the De Luxe Monospar is as follows: Weight empty, 1,7581b.; disposable load, 1,1171b.; span folded, T4ft. roin.; length, 26ft. 4m.; cruising speed at 3,200 r.p.m., 123 m.p.h.; dura tion at cruising speed, 3.8T hr.; initial rate of climb, 700 ft./min.; price, ,£1,085.
