I/OGHT] r.o.g. competition on jth ult. had to be cancelled, as it was impossible to get model* away. On 12th, at Maxwell Park, Mr. Donaldson was experimenting with a tractor hydro.. Bad lad little success ; Mr. Balden had out his twin-tractor r.o.g., and bad several successful flights, timing t6 sees, on several occasions. April 19th and 26th were idle days, owing to the weather. During month work progressing favourably in the workshop, and the committee intend instituting some new scheme* to awaken interest in model work here. On Friday evening, 25lh, the meinliers met :ti the Institute to wish farewell to Mr. J.S. Gordon, who is leaving for West Africa. The chairman, Col. Sillars, with a few remarks, took the opportunity of presenting Mr. Gordon with • keepsake of some utility sub scribed for by his comrades in the club. Mr. Gordon, in thanking the chairman, stated that he was taking some models with him to Africa, and would do his best to still further spread the science of model aeronautics. Sheffield Model Aero Club (35, PRNRHYN ROAD, SHEFFIELD). THE " Colver Cup " and Mr. Manton's Silver Medal for " tractor biplanes " will, weather permitting, be competed for on Saturday, May 3rd, at Sandhouse aerodrome. Intake, 3 p.m. Members please see special added rules in clubroom. Monthly Report.—-Owing to the state of the ground on Easter Monday the r.o.g. models did not fulfill the specifications for the " Colver Cup," nor was the Silver Medal won for " tractor biplanes " through the machines circling. After the close of the contests Mr. E. W. Colver announced a special event for the longest duration flight. Master C. K. Worrall proved the winner with a flight of S r sees. April 14th a general meeting was held at the clubroom, Mr. b. W. olver presiding. It was decided that monthly competitions should be held over until after Whitsuntide, when on that day the President's Challenge Cup for hydro-aeroplanes is to be competed for. To encourage the younger members it was decided to award a special prize each month for hand-launched duration models for novices. Also decided the subscription for hon. members to be zs. 6d. per annum. Mr. W. H. Bagshaw brought down a >V scale model Blcriot, together with plinth, which he had constructed in electro plate. Committee meetings will be held the first and second week each month. S. Eastern Model Ae.C (i, RAILWAY APPROACH, BROCKLEY). DURINU this week-end flying at Woolwich, Lee, Blackheath and Mitcham at usual times. At Klackheath, special attendance is requested at 10.45 a.m. for the purpose of having photographs taken of the club's members and models. OB Monday. Thursday and Friday eueningc next w«elt flying nt Hrackley until dusk. Monthly R,purl. — During the past few weeks the improved weather con ditions have greatly facilitated the out-door experiments of the active members of the S.E.M.Ae.C, and many of them are going ahead with their waterplanes— which must also be capable of rising from and alighting on land—to be used in the first contest for the South Eastern trophy, the rules of which were published on page 450 of FLIGHT, April 19th. These rules have met with unqualified approval by the best known model waterplane flyers, and, judging by the interest already aroused, this competition will prove of exceptional value. The advance reports show that an unusually large selection of models and varied types of floats will be seen when the actual tests are held in June next, and visitors will un doubtedly be amply repaid for any slight trouble experienced in getting to the ground. One very interesting feature of last month's work was the splendid flying done by new large tractor monoplanes constructed by Mr. G. H. Westwood and Mr. A. F. Chinnery. Both these models weigh about 16 ozs., and have made flights of 80 to too yards. The stability exhibited by Mr. Westwood's machine is remarkable, and the duration would do credit to many lighter models. Mr. F. I'lummer has again been doing a large amount of careful experimenting with various models, including tractor monoplanes, both of the r.o.g. and waterplane types, and considerable success has attended Mr. Plummer's work with an enclosed-body biplane. The difference in the flying compared with the same model with open fuselage is interesting. This member's "distance" and "duration" models have been very much in evidence, as have those machines flown by Dr. G. I. McMunn, who obtains considerable success with models fitted with "swept-back" wings. He has also been using the arrow-plane, i.e., a plane surface resembling those of Lieut. Dunn's automatic- suil'ility biplane in plan view, but without the pronounced negative angle near the extremities of the wing. Members should not overlook the possibilities of this type of supporting surface, which is rapidly coming into use on the Continent. Mr. G. Brown has conducted some tests with a twin-tractor mono plane, and obtained good flights which were, however, all circular. The distinguishing feature of this model is an entirely new type of double-surface plane, and the remarkable efficiency shown has easily compensated the constructor for the trouble taken in the making. Mr. C. H. Morgan and Mr. G. R. Eland have done well with "racing" models; the former making flights ofaj-mile, ami Mr. Eland's monoplane was doing duration flights in the neighbourhood of 60 sees. An interesting point in this machine is the placing of the rubber inside instead of outside the longitudinal members of the "A" frame. Mr. L. H. Slatter and Mr. W. J. Williams have done a considerable amount of fine flying with r.o.g. twin-screw models at Wimbledon, and Mr. Slatter has also been flying a tractor monoplane and his well-known hydro-aeroplane. With this model, flights of 30, 33, 38 and 52 sees, have been made after rising from the water ; the best flight terminated with a glide of 17 sees. Mr. Slatter has also conducted some interesting tests on flotational stability. Mr. H. H. Groves had out his steam-driven biplane and monoplane, but the conditions were not favourable for extended flights, and Mr. S. E. Grimstone and Mr. R. W. Prance were flying a " floating tail" and a tractor mono, respectively. Mr. A. D. NJcnolls, Mr. L. B. Morris and Mr. I.. Hatfull with their tractor models, and Mr. F. Dixson and Mr. E. Campbell with twin-propeller monoplanes have flown well. Mr. C. A. Rippon obtained some good flights with his large bamboo biplane, but the best flights made by this member were with a very efficient self-rising monoplane, numerous flights of over 40 sees, being made. Mr. B. Trask has been successful with an r.o.g. monoplane, but had the misfortune to lose a machine at the Lee aerodrome. At this ground Mr. W. A. McLaughlin and Mr. Barrett have repeatedly flown their single-propeller machines. Mr. W. G. Billinghunt has made a number of experiments with a tractor-hydro- monoplane. This machine arises from and alights on the water quite easily, but up to the present only short flights have been made ; several modifications have been introduced and more extended flights may now be anticipated. Mr. l'.illinglmrst's ordinary self-rising tractor monoplane has also been flown with fair success. The exhibition, which it was intended should have been held in May, has been postponed, as members are busily engaged on the construction of their models for the South Eastern Trophy Competition. The hon. sec, Mr. A. B. Clark, will be pleased to hear from anyone interested in model aviation, and full particulars of proposed visits to outlying districts will be gladly supplied if application be made to the above address. The Croydon and District Branch (136A. HIGH STREET, CROYDON). Meiith/y Report. — Much valuable work has been done during April, although the weather at times has not been favourable. Hydro-models seem to have received most attention, and Messrs. Carter, Smither, Young, Pavely, and Hart have been out with these models. Messrs. Pavely and Bell have been MAY 3, 1913. most successful. Mr. Bell has had some flights, which for practically his first attempt at hydro-models, are a great credit to him. His model rises and alights with the utmost regularity. Several members are busy on new hydros., so there should be a good display of these models short y With r.o.g models, Messrs. Young, Bell, Pavely, Smither and Hart have all had successful flights : Mr. Smitber's latest r.o.g. model has made some magnificent flights at Sander- stead in the evenings. The weather now shows signs of improving, and the flying season is here. In view of these facts there seems to be a greater enthu siasm among members, which is a good sign for the future. The club intends to hold open competitions all through the summer, notices of which will be duly announced in FLIGHT from time to time. Wimbledon and District Model Aero Club (S9»i ST. PHILLIPS ROAD, LAVENDER HILL, S.W.). FLYING on Saturday afternoon at 2.30. Sunday, 11 and 3, on the Plain on Wimbledon Common. Monthly Report,—This club has recently been formed, and it is hoped that all in the district interested in model flying will become members. A good deal of flying has been done during the past month by members with all types of machines. Williams, Slatter and Laing have flown their r.o.g. monoplanes, obtaining excellent durations. Powell, Easdale, Chown, Clements, Laing and Eads have all flown models launched by hand. Easdale has an interesting tractor ; though less than 2 ft. long it has done over 30 sees, duration. Tucker has a large tractor which rises from the ground and flies 200 yds. Slatter, Chown and Easdale have out hydros., with varying success. Windsor Model and Gilding Club (10, ALMA RD., WINDSOR). Monthly Report.—Little or no model flying has been done this month, the members having ah been occupied on the new glider. The club has been fortunate enough to acquire some workshops with a total floor space of about 1,200 sq. ft., so that it will be possible to erect the machine full size. _ For con venience of transport it has been made in^ three sections—a 6 ft. 6 in. middle section and two 9 ft. 6 in. end sections—making a total span of 25 ft. The chord and gap is 4 ft. 6 in. The control is by interconnected ailerons, with rudder and rear elevator. The ailerons and elevator are controlled by universal lever, and the rudder by a foot-bar. The planes have been built with an i8-in. flexible trailing-edge. The ribs are of T-section, very strong and light. Some very novel ahcet-stcel tfiMiugs have been designed and made by Mr, G. Petit, the section joints being extremely crcdiiabie, The chassis is of ash, with two rubber-sprung 24-in. wheels. An aluminium bucket-seat is being fitted. The ailerons are hinged to the rear spar, the control wire to be carried by pulleys. Excepting the chassis, the material used throughout is spruce. Estimating the weight of the machine as 75 lbs., and the pilot as 150 lbs., the glider will be loaded about x lb. per sq. ft., as there is 225 sq. ft. of supporting surface. It is to be single-surfaced, with the main spars covered in underneath. The club have applied for permission to exhibit it at the Royal Counties Show in June, and it is hoped that it will be granted. As the club is taking up the more practical side of aviation, it is hoped that any enthusiasts in the locality not yet members will shortly become so. Apply to the secretaries, S. Camm and S. Barton, as above. Yorkshire Ae C. (Model Sec.) (53, WEST STREET, LEEDSI. MAY 3RD.—Members giving flying exhibition at Bramley Carnival, near Leeds, in afternoon and evening.
