IfLlGHT we send you photographs (reproduced herewith) of our full-size machine, which we have built as a result of our successful experiments with models. We patented it in 1909. The patent No. is 20846, and we append particulars of size which, with the photograph now sent, will enable you to see the principles upon which we have built:—Length, 24 ft.; width, 16 ft.; height, 10 ft. ; surface, 350 ft. ; weight with pilot, 450 lbs. The principal objects we studied to accomplish in creating our machine were—1st, safety; 2nd, natural stability ; 3rd, simplicity in steering, elevating, &c. ; 4th, small motive power ; finally, low cost of building. The lifting surface is so arranged that, in the event of the engine stopping, the machine will descend in a series of glides, and settle on a level base. It is seeing that our ideas are apparently coming into vogue that it seems advisable to explain our position. VICTOR F. FORISES. Leigh-on-Sea. ARTHUR J. ARNOLD. Cylinder Cleaning. [1419] In your edition of the 4th inst., under the heading "Air Eddies," you were good enough to refer to us as the originators of a new method of cylinder cleaning, but we feel it is only fair to the patentees to point out to your readers that the process referred to is the "Cyclean" (Watkins Patent), the agency of which has been granted to us, and we are at any time willing to give anyone interested a demonstration at our works, Byfleet Road, Weybridge (or upon their own premises by appointment), of this time and expense-saving device. ITALA AUTOMOBILES LTD. (CHARLES JAMES FOX, Works Manager.) Byfleet Road, Weybiidge. MODELS. The Limit of Long-Distance Flyers Propelled by Elastic. [1420] I must apologise to Mr. Hill for my delay in replying to his interesting letter (1397), but the "tuning up" of batches of what he would presumably term " flying elasticks" has left me with very little spare time. Mr. Hill asks, " Is stating the limits of rubber making an attack upon it ? " In his former letter (1368) he speaks of "power-driven scale models "as being" real model aeroplanes," the inference being that machines propelled by rubber are not of this category at all. What is this but a deprecation of rubber as a motive power ? It is interesting to note that in view of his strong views on the subject of rubber, Mr. Hill should exhibit at the recent Model Engineer Exhibition a model fitted with this means of propulsion. Mr. Hill seems to classify all long-distance models under the heading of " flying sticks." But why blame the machines when the rules that govern the competitions are really at fault? Whatever may be the custom among theoreticians, it is a fact that among prac'ical model makers " power " and "torque "are inter changeable terms, and that the power of a rubber motor is actually the "torque." As a practical model maker I must confess that I am quite unable to understand Mr. Hill's remarks about the "power" (does he mean " torque " ?) of rubber motors. He states a typical case of a 6-strand motor which runs out in 30 sees. Then he speaks of a 12-strand motor running out in the same time. Experience teaches that a [2-strand motor runs at approximately twice the speed of a 6-strand one, added to which it is impossible to get anything like the number of turns on the former as on the latter. Gearing is not practicable, and the use of gigantic propellers makes the model too obvious a "freak." Then he states a case of the same 12-strand motor running for 60 sees., which is even harder to understand. Unless it were of exceptional length, the comparative fewness of the turns and the terrific speed of its propeller would make this quite out of the question. *, Surbiton. R. j*. MANN. Aviation at the Scottish National Exhibition. [1421] With further reference to my letter, No. 1405, may I add a few remarks to guide the footsteps of the unwary scale model builder. I have just received my model back from the aviation pavilion in the following condition :—Propeller and one tyre stolen, rudder, rudder post and control lever broken. This particular model, by the way, has been one of the most fortunate of the show as regards breakages. It is remarkable that all the "aviation" goods, such as ships' binnacles, sounding logs, steam engines, &c, which were dumped down in the Aviation Hall have, apparently, NOVEMBER II, 1911. escaped damage. To any of your readers who contemplate exhibiting their scale models in a public place, I would suggest the following hints if they cannot succeed in extracting a guarantee from the promoters:—Secure propeller strongly to prevent it being revolved; lock the chassis wheels to prevent the machine being wheeled about; pass a wire round the chassis wheels and tyres to prevent the latter being removed ; lock all control levers, and also wire strainers by passing a stout wire through the eyes of the screws and the barrel. In short, a model for exhibition purposes must be made as strong as possible, for intending exhibitors must remember that glass cases are not supplied gratis. In conclusion, I beg to extend my utmost sympathy and that of the model exhibitors here to those who have sent models from outside of Glasgow, and I trust that they will have gained from their sad experience of the Scottish National Exhibition.
