JDOHf] Supposing a full-size monoplane was constructed on the same principle as the Clarke flyer (elevator in front and propeller at back), would it have any advantage on the present system of monoplanes ? Stourbridge Park. OWEN. [It has always seemed to us that the diminishing slip-stream from the tractor-screw must affect the natural stability of models thus fitted, calling as it does for a variable attitude of the elevator during flight- The draught from the propeller situated behind flows clear of all surfaces. A correspondent recently suggested a device for an automatic tail.—ED.] MODEL DEMOISELLE. [931] With regard to Mr. Lockett's letter (No. 717), I also am making a model Demoiselle, and would like to suggest the following methods of fixing an elastic motor. The enclosed sketches will, I hope, make the explanations clear. The wood used is^-in. square section birch. At A and B a piece of wood is nailed and glued to the framework, and at C is carefully bored to take the propeller- shaft. D is a piece of thin iron wire bent to form a skid, and passing through the horizontal tie-piece and top member of the framework, and projecting about J in. above the latter, so that it can stick into the piece of wood, E, which is then glued in position. F is a tension-wire, the most suitable kind, to my mind, being that sold by florists at id. a reel. A geared motor, I should say, could be most easily fitted by putting the elastic inside the framework, and by putting the gearing- wheels one above the other on the member AB. Another piece of wood, G, would then have to be added parallel to AB, to take the other end of the axle of the propeller. Cowes. D. E. MOISELLE. CAMBERING RIBS. [932] I should advise Mr. A. G. Adams (731) to curve the ribs of his plane by steaming them. If the desired curve is drawn on paper, the ribs, after being softened in the steam from a kettle spout, can be easily bent to that curve, and if they are tied in a bundle, one on top of the other, before they have dried, and are lightly steamed again, this will ensure them all drying and hardening into the same shape. The most suitable amount of incidence can best be found by experiment. With regard to fixing one plane above the other, I did not see letter No. 632, but I may mention that I have had trouble with planes supported on stanchions from several causes, and that I now construct the frame of four fore and aft members, and fix the planes to these. I have found built up planes unsatisfactory, and am now trying thin wood. Liverpool. S. P. ELLIOTT, Lieut. R.N.R. QUERIES. t933] A. Lowe (Newtown) inquires as to the best power to drive a model Farman biplane of 3 ft. span, weighing about 7 ozs. without wheels and motor. The lifting area is about 537 ins. [934] J- Russell (Clapham) would he glad to hear from any readers who have had experience with miniature petrol motors He wants to know what horse-power would be required to drive a model of from 3 to 3^ ft. span. [935] "A Beginner" (Lowestoft) wishes to know the best models to commence building, as he has had no experience, and has not seen an aeroplane or balloon. He wishes to have weight, measurements, materials, &c , of such models. [936] J. W. Lane (Wolverton) wishes to have particulars of the Ridley kite which was illustrated in these columns a little while ago. REPLY. [937] E. A. Earley (North Kensington). The model aeroplane you mention should fly quite satisfactorily with a propeller if properly balanced. DECSMBBR 3, 1910. AIRSHIP NEWS. The Willows Airship. ON Saturday last Mr. Willows made another attempt to com plete his journey to Paris by airship, and started off from Lamottc- Breuil at half-past ten. The fog was very dense, and Mr. Willows was obliged to steer his ship entirely by the compass. His diffi culties were added to by the intense cold freezing up the carburettor. From this cause the engine ran very erratically, and was at last put out of commission by a shaft breaking when the airship was passing over Rully. An easy landing was made, and the shaft repaired, after which the airship rose again and made a fresh start in the dark. While over Senlis the motor stopped again, owing to the frost, and the airship drifted on for some little way, eventually a suitable landing place presenting itself at Albert, and there Mr. Willows descended. After waiting on Monday for the wind to change, Mr. Willows decided, as the balloon had lost a quantity of gas, to deflate it and send it back to Lamotte-Breuil in order to make a fresh start. 0 ® ® ® PUBLICATIONS RECEIVED.
