DECEMBER 3, 1915. [fQSBT] ALL communications in connection with this «»o»inn ,.> u w , I—— London WC Corres^nH.nf * add'essed l.° ^ Model Editor, " FLIGHT." 44, St. Martin's Lane, *odeU „ AT.'.-S? POTdemS "e reqUCSted ,l° W"te °n °De Side of the «»P« on'y-Paper Models in Australia. THE notes on the making of paper models which have appeared in these columns from time to time have led to some work beine done in this direction in Australia, as the following letter from Mr M A Braithwaite, of Melbourne, will show : " I read your article in ' FLIGHT,' NO. 35, Vol. 7 (just to hand), on paper models with mtch interest, as I have, together with — r..t ~. *,...,. wheels, supported on a a-in. axle, made from a cycle spoke. The two V's are made from i6-gauge steel wire. The rear skid is made from bamboo J in. by ,'„ section. " The main planes, tail, and rudder aie made of steel wire and covered with Jap silk. The top main plane has 7 ribs, and is strengthened by a piece of U section steel ribing, running along the front edge for the greater part of its length. the assistance of a friend, Mr. W. B. Kirkland, been building a number of machines of the type advocated, and although they aie not actually scale models of any particular machine, they are pro portioned as near as possible without being actually to scale. I am enclosing the drawings of two of our manufactures. " As will be seen one of the machines is of Farman design, and although this model is slightly too heavy to be much of a flyer it does some good glides at odd times. The tail booms are made of paper rolled into a cylinder. The chassis of this and all the machines are constructed in the same manner, and are remarkably strong. " In building the models we use no other material than paper, except that a portion of a match is used for the axles, while the wheels run on stub axles of pins pushed into the match. The wheels themselves are made from visiting cards and are disc. The models are all weighted in front with brass paper fasteners, the planes are cambered and usually of eight inches span. As regards actual flying they are decidedly graceful in appearance and very real in their actions, especially when they land and taxi along the ground. The gliding angle is I in 5-6. This is rather steep, but as one can rarely get a long flight indoors it does not much matter. In flight they carry out all manner of evolutions and stunts, and by throwing them straight up to a height of ten feet they perform a loop of two feet six inches or three feet in diameter, and upon recovering from the dive fly off as if they were actually under control." A New Zealand Model. From Devonport, Auckland, N.Z., Mr. A. E. Knowles sends us the following particulars of an interesting model which he has built :— " I am sending, herewith, drawings of a tractor biplane designed and constructed by myself. "The fuse/age, which is 3 ft. long, is oval in section. The ribs are steamed to the required shape and are laid on three birch longerons, j in. by T| in. The front is finished off with a light brass bearing, and the rear is brought to a vertical knife-edge. At the end of this the rudder is hinged. The whole juselage is covered with silk, except where a hole for a pilot's seat is fitted, and except to be given to the front rubber hook, when enables attention necessary. " The chassis consists of a central,'skid of J in. by TV «)• bamboo, a compression strut of the same material and a pair of 2-m. disc " The propeller is 10 ins. diam. and 15 in*, pitch, and is driven by eight strands of i in. strip rubber. The best flight to date is 72 yards and 31 sees., both being obtained in the same flight, but I hope to get something better from it yet. The above flight was r.o.g." Mr. A. E. Knowles concludes his letter with the practical sug gestion that he would like to correspond with an enthusiast on this side of the world, so that they might mutually assist each other in their ideas. If any of our readers would care to take up the suggestion we shall be pleased to give them Mr. Knowles' full addreSS- ® ® ® ® AFFILIATED MODEL CLUBS DIARY. AND REPORTS. Paddington and Districts (77, SWINDKRBY ROAD, WEMBLEY). A SPECIAL general meeting will be held at yy, Swinderby Road, Wembley, on Saturday, December 4th, at 6 p.m. Several interesting items are down for discussion, namely ; The future work of the club ; recording performances of models in actual flight; development of the compressed air model; proposed wind tunnel. The committee would be pleased to see any past or present members now serving their King and country if they happen to be on leave at this date. Monthly Report,—The few remaining members who are not on active service have done little flying of note lately, but mention should be made of the activities of Messrs. J. R. Barrett, T. Carter, W. E. Evans, H. R. Weston, and H. S. Woolley. Work on compressed air models is proceeding as well as present cir cumstances permit. It is gratifying to know that the club anticipates no difficulty in holding together until the war is over. UNAFFILIATED CLUBS. Liverpool Aero Research Club (62, CEDAR GROVE, LIVERPOOL). Monthly Report.—-The month of November has been the quietest of the year, occasioned by the severe weather and business pressure of memters. During the beginning of month B. Tear put in some good h.I. duration flying. Nov. 20th saw the appearance of the new divided tail H military "-type mono., which has been very well improved in appearance, the previous mcdel being nicknamed the " angry wasp," owing to its rather ungainly appearance, despite a fair efficiency. Members were glad to learn that A, G. Pugh, wounded in France, was discharged from the General Hospital, Burton-on-Trent, on the 13th. Another member, J. Kilshaw, has now joined the 5th King's Liverpool Regiment. Scottish Ae.S. Model Ae.C (5, DOUNE QUADRANT, GLASGOW). No flying meetirgs will be held during the coming month. Monthly Report.—During the past month no flying has taken place. Two more members of the club are nowon service, namely, Mr. Ian S. Ross, Army Service Corps, and Mr. A. P. Mackim, Royal Flying Corps.
