\J[iGHf dimensions accurately from a photograph, some of which they cannot even see. It has been said that photography cannot lie—well, all I can say is that whoever said it didn't know much about photography. The Kite and Model Aeroplane Association, The Hon. Secretary of the above Association—Mr. W. H. Alcehurst (whose untiring energy and zeal have done so much towards its success)—has sent me particulars with respect to the affiliation of other clubs ; the question is one of paramount import ance with respect to model aeroplaning. It is most earnestly to be hoped that no club will permit any personal or local circumstances to stand in the way of such affiliation, which in view of any inter national contest becomes, one might say, of national importance. I regret to have to state that the French have the lead of us even in this matter, and nothing but a united front is at all likely to avert disaster. I refer not to rubber-driven but power-driven models, and an international contest could scarcely be limited to models propelled solely by rubber. Lastly, there is that distinction between an ordinary record and that on which the hall mark of proper official recognition has been set, which makes all the difference—even more so afterwards, perhaps, than at the actual time of the event. Notes. I should much like to receive from the Blackheath Aero Club some particulars with respect to the single-tractor screw monoplane mentioned in last week's issue. There appear to be very great discrepancies ie the amount of energy that can be stored up in a pound of rubber. Mr. G. T. R. Hill (letter I397> October 2lst) states, quoting from an old copy of FLIGHT, that j lb. of rubber can store upwards of 1,000 ft. lb., which gives us some 1,300ft. lb. per lb. weight of rubber. Obtaining my information from what I had every reason to think was a reliable source, I have stated it to be 300 ft. lb. The question is of some importance. I should be glad to hear of any really reliable experi ments on the matter. I might just mention that with 2L% cz. (36 strands 1 yard each), unluhricated, 200 turns only, I have obtained some 15 ft. lb., 12 oz. being raised 19 ft. in 5 sees. This can plausibly be shown to be in the nature of 300 to 500 ft. lb. so far as actual practice goes. » • • A correspondent wishes to know where he can purchase plans for building a "Fleming Williams" model. Will some reader kinily supply this information ? E. N. Joyce (St. Margaret's Bay, near Dover), would be glad to know if there is any prospect of a model club being started in that vicinity. A correspondent from Lincoln states that attempts have been made there to start a model club but failed because Lincolnians say it is only a sport fit for small school boys. Exactly so—Lincoln is not alone in this opinion—this is one of the popular errors that we must all do our best to remove. Replies in Brief. C. R. TAYLOR.—Thanks for your letter. It has been thought best to close the discussion—partly for the very reasons you state. F. PLUMMBR —Yes ; but what was the type of your propeller, also its pitch, &c. ? Moreover, I take it your propeller was rotating only, and not advancing through the air. Full particulars are always necessary, or no correct comparisons can be made. C. HAY.—You are quite correct as to the efficiency of the pro pellers you name ; reduce their weight by carefully sandpapering, &c., to one half, and you will be still more successful. S. H. S. M.—It is the dynamic, not the static, thrust of a propeller that we really want to know. DECEMBER 9, 1911. PORTRAITS ALREADY PUBLISHED. Astley, H. J. D....
