FLIGHT, SEPTEMBER 9, 1932 CORRESPONDENCE 7 he Editor does not hold himself responsible for opinions expressed by correspondents. The names and addresses of the writers, not necessarily for publication, must in all cases accompany letters intended for insertion in these columns. ENGLAND-AUSTRALIA AIR MAIL. [2809] In your issue dated May 27, 1932, on page 468, you quote The Times, which apparently published a state ment that this company refused to undertake the building and repair of aircraft for use on the proposed Australia- England service, because the undersigned was being given a subordinate position in the scheme. We hasten to contradict this statement. The correct position is that one of the representatives of the proposed combine promised to submit a proposal to us for consideration. We have signified our willingness to consider such a proposal. At the time of writing, however, it has not been received. Whilst on this subject we would mention that it is the policy of this company to advocate the calling of tenders for all aerial mail contracts and renewals. The matter of a position in the proposed combine for the undersigned has not been discussed, and we state quite emphatically that the negotiations have not been inter rupted by this company. We would be obliged if you would kindly publish this correction. LARKIN AIRCRAFT SUPPLY CO., LTD. A. LARKIN, Managing Director. Melbourne, July 22, 1932. WEIGHT OF SMOOTH DOPE FINISHES. [2810] We note in an article in your issue of July 22, dealing with the products of a well-known firm of aeroplane dope manufacturers, a statement that the high gloss finish on the fabric-covered fuselages of some machines makes them much heavier than when doped with an ordinary standard finish. There is a remote possibility that this " weighty " state ment may discourage owners from specifying Titanine " Satin Finish " on their machines, though we do not suggest for a moment that it was made with this intention. If such a statement needed refutation it surely is to be found in the fact that one of the many " Puss Moths " treated with Titanine " Satin Finish " (the " car " finish for aeroplanes) was used by Mr. Mollison on his Atlantic flight, a venture upon which we have no doubt he con sidered that any slight increase in weight that might be necessary to produce the smooth " Satin Finish," by v\hich friction is reduced to a minimum, was well worth it. We have not the figures available of the actual increase in weight on this machine over " normal " doping, but in general it may be said that the " Satin Finish " effect can be obtained from a dope deposit which is not in excess of that found on many machines in general use, which are doped with older-fashioned schemes leaving a rougher surface. For Titanine-Emaillite Limited. T. W. H. WARD, London, August 22, 1932. (Managing Director). AIRCRAFT MODELS AT THE MODEL ENGINEERING EXHIBITION "ODEL aircraft and their makers are well repre sented at the fourteenth annual Model Engineer ing Exhibition which is taking place at the Royal Horticultural Hall, Westminster, until September 10. A large variety of models is exhibited by Warneford, of Greenwich, S.E.10, who are now producing a new type called the " Silver Flash." It is a monoplane made entirely of a metal which is neither aluminium nor duralumin, but a " secret " metal, the nature of which is not disclosed. Special features of the " Silver Flash " are the folding wing, which is also adjustable, and full adjust ment of the tail plane and rudder. Its weight is \ oz., and its performance is claimed to be as follows: —Speed 10 m.p.h., distance of flight 150 ft., and ceiling 20 ft. It will also rise from the ground. Warneford's produced over half-a-million models last year. The Model Aircraft Club, of which Mr. A. E. Jones, the manufacturei of models, is Hon. Secretary, reveals <-,ome interesting and capable work of its members, while on the stand of the Society of Model Aeronautical En- M gineers are several imposing types designed by Capt. C. E. Bowden, R.A.S.C. Amongst them is the " Bowden Gull," i large low-wing cantilever monoplane fitted with a 14-c.c. special Westbury " Atom Junior " 2-stroke engine.. The weight of this engine with the tank and propeller is 1 lb. 8 oz. Ignition is obtained with a torch battery and coil. The accumulator is plugged in on the ground for starting up and a clock is fitted to the model to regulate the duration of flight by mechanically switching off the engine. This monoplane has a wing span of 9 ft., a wing area of 8.3 sq. ft. and overall length of 47£ in. The total weight is 8 lb. 2 oz. and wing loading 14.4 oz. per sq. ft. The machine can be fitted with a small camera for obtaining aerial photographs. Capt. Bowden shows another large petrol-engined model known as the " Kanga," which holds the British record (unconfirmed) for petrol-engined models. This was obtained with a flight of 1 min. 11 sec, which can be automatically improved upon by regulating the clock which closes the engine throttle. The " Kanga " has a Westbury 20-c.c, 2-stroke engine, and is a biplane. Wire less control can be experimented with on this model. A. J. Holladay & Co., Ltd., of 3, Aldermanbury, E.C.2, exhibit cheap toy types of popular aircraft designed to introduce the youthful beginner to the making of models. They do not fly, but they teach a boy how the major parts of models fit in relation to each other. The sections are made of mahogany and brass and are very easy to assemble. Incidentally, a beautiful model of the four- masted barque " Port Jackson " on show was made by Mr. G. M. Cox, a flying instructor at the de Havilland ^lying School at Hatfield. m m m m National Aviation Day Displays DISPLAYS in connection with Sir Alan Cobham's National Aviation Day Campaign will be held as follows : •— Sept. 10 and 11, Edinburgh, Silverknowes, Davidson's Mains; Sept. 12, Lanark, Westbank Farm; Sept. 13, Alloa, The Old Aerodrome; Sept. 14, Buckhaven, Banbeath, Windygates-Leven Road; Sept. 15, Anstruthcr, Rennyhill; Sept. 16, Haddington, Lennoxlove Acredales, Gifford Road; Sept. 17 and 18, Glasgow, Moorpark Aerodrome; Sept. 19, Falkirk, West Mains Farm, Grangemouth Road : Sept, 20, St. Andrews, Salgove, Cupar Road; Sept. 21, Perth, Woodhead ot Mailer ; Sept. 22, Inverness, Seafield, Longman Road ; Sept. 23, Fraserburgh, Mid-Ardlaw, New Pitsligo Road. Fireproof Dress BEFORE a number of scientific witnesses Mile. Suzanne Biget, of Lille, wearing a costume of her own invention made principally of asbestos treated with a special liquid, was wrapped in cotton wool, soaked in petrol, and set on fire; she came through the ordeal none the worse. The fireproof dress is reported to be specially designed for aeroplane pilots. m & m m PUBLICATIONS RECEIVED Questions and Answers in Meterology.
