DECEMBER 16, 1911. I/IICHT) MR. H. P. WOOD'S INTERESTING AUSTRALIAN MODEL.—The result of two lyears' experiments and twenty-nine models. Best flight 300 yards. Replies in Brief. S.'SAUNDERS.—You will be able to draw your own conclusions from our remarks above re petrol motors. We are afraid that any thing less than I h.p. is out of the question. The diameter of your propeller is certainly too small. Re your question with respect to •coils, consult the Economic Electric Co., of Twickenham. Why not try a carbonic acid gas motor ? Excellent results have been •obtained by these in France. R. BAGLEY.—We are not at all surprised that you have had no success with your model. In the first place, it is much too heavy, ® ® and in the second, it is under-powered. Reduce the weight as much as you can, 3 ozs. if possible. Don't use umbrella ribs ; they can only be used successfully in much larger models. Use 28 strands of T. W. K. Clarke's jV-in. rubber, and as large a propeller as your machine allows, centrale type, and let us know the result. Lighten your propeller by sandpapering, and make the blade hollow-faced. No other kind of motor save a rubber one is possible with a model of this size, viz., II ozs. Try rising from a strip of linoleum. G. BRENT, J. EDWARDS.—Received with thanks, and shall use as soon as opportunity offers. ® ® PROGRESS OF FLIGHT ABOUT THE COUNTRY. NOTE.—Addresses, temporary or permanent, follow in each case the names of the clubs, where communications of our readers can be addressed direct to the Secretary. We would ask Club Secretaries in future to see that the notes regarding their Clubs reach the Editor of FLIGHT, 44, St. Martin's Lane, London, W.C., by first post Tuesday at latest. MODEL CLUBS. Aberdeen Aero Club (387, HOLBURN STREET, ABERDEEN). RAIN completely spoiled meeting which was to be held on Saturday, only three members turning up at the flying ground. Some good flights were nevertheless obtained. The distance com petition was postponed until the first fine Saturday. In the middle of the week Mr. L. Gray had some excellent duration flights of 30, 27 and 25 seconds. A workshop and clubroom have been acquired at No. 403, Holburn Street, where members will have every en couragement for the execution of model work. Meeting to-day Saturday) at Kincorth, at 3 p.m. as usual. A meeting will be held at night, at 7 p.m., in the new clubroom. It is to be hoped there will be a large turn out of members on both occasions. Aero Models Association (NORTH METROPOLITAN BRANCH). A SOCIAL meeting of members of the North Metropolitan Branch will be held at 15, Highgate Avenue, Highgate, N., on the •evening of Saturday, December 23rd, at 7.30 p.m. It is hoped that members and prospective members will make a point of being present, and the honorary secretaries Mr. Malcolm B. Ross, 15, Highgate Avenue, N., and H. Brosse, 9, Clifton Road, Crouch End, N., will be glad if they will bring with them anything of interest in connection with aero-models. Bath and Somerset Aero Club (u, ELM PLACE, BATH). A VERY interesting and instructive lecture was given by Dr. E. White, at the Church Institute, Bath, on Friday, the 8th inst., entitled " Aeroplanes and Gliders." Considerable amusement was caused as to the correct pronunciation of the various French words used in aviation. On the motion of Mr. G. E. Page, a hearty vote of thanks was passed to the lecturer. All members are looking forward to the summer, when competitions and flying meetings will be held. Enthusiasm during the winter months, alas ! is allowed to slacken. The hon. sec, Mr. S. H. Baker, of the above address, will be pleased to receive makers' catalogues for the use of the club members. Birmingham Aero Club (8, FREDERICK ROAD, EDGBASTON). THE annual general meeting of the above club takes place on January 3rd at 8 p.m. at 9, Bjlgrave Road. The report of the club's doings during the past year will be read, as well as the balance-sheet. All pa«t, present and prospective members are invited to attend. At the last meeting it was decided that the subscription of all senior members joining after December 31st shall be one guinea yearly 01 $s. $d. quarterly, but for members joining before that date, the subscriution to be 31. quarterly. The junior members' subscription will be $s. yearly. Last Saturday saw Mr. W. Lunn trying to get a model to rise from the ground, but his experiments were put to an end by a buckled wheel. He then brought out his model the " Tumbler Pigeon," and gave an exhibition of what looked like tent pegging. Mr. H. Grahame Black, a new member, was getting some excellent flights with a Gordon Jones model, carrying a " passenger " on board. On Sunday further experiments were carried out with Mr. E. Trykle's mod'l glider. The cords to the planes were first tried 30 feet in length, and the glider, flying successfully at this height another 30 feet was added to the cords, after this another 30 ieet and still another 30 feet of cord was added, by this time the supply of string giving out. The glider was now soaring nearly 120 feet high ; there it remained for nearly half an hour, making quite a splendid sight and causing a deal of excitement when it made a dive, but recovered itself, and continued its steady flight. Next week-end we hope to be able to get the glider up at greater heights still, when attempts to photograph it will be m^de. This glider embodies the principle of Mr. E. Trykle's successful model, and is to the scale of the full-sized glider which he and Mr. B. W. Beeby will be starting shortly to construct. Blackheath Aero Club (196, BROCKLEY ROAD, BROCKLEY, S.E.). ON Saturday last several members were on the Kidbrooke ground practising with various types of models for nearly two hours. The ground was in such a wretched condition, being several inches under water, that it speaks volumes for the enthusiasm of those members who " paddled " over and over the ground to fetch their models. Many fine flights were made by Messrs. Dollittle, Williams, Slatter, Collins and Clark, and the latter's singlestick Victor monoplane showed great judgment by flying through the branches of some tall trees instead of coming to " roost" on the top of them, as is usually the case. At the Grove Park Aerodrome, Messrs. Woollard, I'izey, and 1093
