MAY 24, 1913. I/UOHT) Mr. M. B. Ross's Olympia model. trophies, and the scientific nature of its competitions is not unduly assisted by such. In its competitions, up to the coming season, a gold medal could be won for a hand-launched machine for merely the longest distance flown, and also another for longest distance and stability (hand launched and r.o.g.), minimum weight of the fore going 4-oz. ; in addition to these a gold medal was also awarded for an r.o.g. machine (duration and stability) for a model of 8 ozs. minimum. This year the two first-named competitions are for r.o.g. machines only, all hand-launched machines being relegated to junior competitions. Personally, the writer would like to see the gold medals removed from all the above, from the sporting side of the question altogether, further award than the kudos gamed, yet how many firms might with ntwiidifiMn profit u> themselves set up a research laboratory <>n model linev Model Club for Ecclesall and District. Mr. J. 11. Jude (50, Crescent Road, Sheffield) writes, saying : " A model club under the above title has. recently oeen formed in this district, and is in a sound position financially. It possesses a man- carrying biplane glider very neat completion ; but in order that the club may be a success during the coming season it requires more members, and 1 should l>e very glad for anyone in the Sheffield district who is interested in model aviation to com municate with me at the above address. The following prizes have been offered for compeliti- m among members : Mr. M. Kavanagh, a silver cup and two medals; Mi. li. VYoolhousc, a bronze aviation figure j Mr. A. Atkinson, a silver medal, l>esides others in view, so that there is no lack of prises." Mr. W. H. Norton's Twin-Winding System. We give this week an illustration of the particular type of twin-winder used by the above, who says in his communication : " Seeing your illustration of Mr. Iloulberg's system in a recent issue of Kl.lOHT (April a6th), I thought I would send you an illustration of a system which I have used eversinoe I took up model aeroplaning. 1 may say 1 am a firm believer in this system, as the advantages are so obvious. Possibly the reason it has not been mote gMMnlfo taken up is that it is a little more trouble in construction, but I think the advantages more than compensate for any little additional trouble required." Mr. M. B. Ross's Olympia Model. The following are the chief particulars of this model, which exhibits several very interesting points in design and construction : Span, 30 ins. ; average chord, 5 ins. ; weight, 12 ozs.; area of supporting surface, 286 sq. ins. ; loading, 8 ozs. per sq. it. Non- lifting tail, but the top surface is camliered. Both the planes, tail, &c, are double-surfaced. The four struts supporting the planes are of streamline form. The four-bladed propeller has a diameter o» Mr. G. Rowland's Olympia model. and the founding and awarding of a gold medal and a prize of ten pounds yearly for the best piece of model research work done during the year. Such an award would have in course of time a very high value, and would undoubtedly (when aviation becomes more established) be keenly competed for. Unless something of this kind is done, the views put forth by Mr. Brasnett will undoubtedly come to pass, and we shall have model aeroplaning, like model locomotives, &c, degenerating into nothing more nor less than " splendid pieces of workmanship." It is a lamentable fact that, so far as model work generally in this country is concerned, no prizes or awards (so far as the writer knows) are offered for experimental or research work ; by model, I refer to any kind or type of model, not solely to an aeronautical one. At the present time any such work must be carried out by individual effort often at considerable personal expense, and without any 10 ins. and a pitch 01 17 ins. The motor consists 01 two skein« o rubber on a H section detachable motor-rod. The skid is of ash T section, with dished wooden wheels. Trie elevation is adjusted by sliding Ihe/usela^ along through four bearings attached to the two centre compression-struts and the extended portion* of the skids. Some Good Flights with a Steam-Driven Blplans. Mr. H. H. Grovel, writing re his Olytnpia biplane model (illustrated in a recent issue), ssys : " I just sen-i you a line to let you know that this model has, after several mijhaps, at length justified its existence. On Bank Holiday last, I was sjccestful in getting three reilly very successful flights out of it: the first of some 60D yards, at an altitude of about 40 ft. ; a second, circles to the left and about 30 sees, duration ; and a third flight, consisting of a large circle to the left, at a height of about 35 ft., which terminated 577
