FEBRUARY 12, 1910. a useful load of 201 kilogs. He is now actively at work teaching several military officers, while Kuller has the Government Antoinette pupils under his charge. New Belgian Prizes. M. GEORGES BRICHANT, a well-known Belgian sportsman, has just founded four prizes of ^100 each. The first will be used to provide a cup for a balloon •contest, while the others will be awarded by the Belgian Aero Club to the Belgian aviators who fly and carry on an aeroplane the greatest load in a given time. A New German Flyer. ON the 4th inst., a monoplane, which has been designed and built by Herr Hilsmann, was given its first trials at Essen, and several long jumps of 60 to 100 metres were made. The Parseval Monoplane. THE monoplane which Major von Parseval recently designed has now been completed and is being taken to Plau, in Mecklenburg, where it will be tested along the shore of the lake. The machine has a span of 14 metres, while it is 7 metres long and is fitted with a motor of 114-h.p. Paulhan at Denver. ON the 2nd, 3rd and 4th inst. Paulhan was giving exhibition flights at Denver, but in view of the intense cold, which numbed his iimbs, did not attempt any lengthy or high flights. On the 4th he met with a mishap, as his Henry Farman machine fouled one of the fences round the course. Several people were knocked over, and Paulhan was thrown out, but no one was \f&m\ seriously injured; the aeroplane, however, was consider ably damaged. Curtiss after Endurance Records. IT is reported from New York that with a view to making a determined attempt to beat the duration records, a big biplane is being built to the designs of Mr. Glenn Curtiss, which will have planes twice the size of the ones on his present machine, 'with which he has made speed records. He will continue to use a 25-h.p. 4-cyl. motor. Bregi in South America. LARGE crowds assembled to see Signor E. Bregi make his flights at Buszaco, near Buenos Ayres, on his Voisin machine on Sunday last. Two trials were made, tehe first lasting for 8 mins. 17 sees., and the second for 8 mins. 53 sees. The greatest altitude was attained in the latter test, when Bregi was at times flying at a height of 100 ft. ® ® ® ® AIRSHIP NEWS. Accident to the Forlanini Dirigible. AN unfortunate mishap befell the Forlanini dirigible, of which we gave several illustrations last week, during a trial trip from its shed at Crescenzago to Parie. When about 3 kiloms. from Parie one of the motors stopped, and Signor Forlanini decided to land in .order to effect repairs. This was accomplished satisfactorily, but when starting again the balloon was driven against a tree and a hole torn in the envelope. This allowed the gas to escape, and although the vessel rose to a fair height, it suddenly dropped to earth again, but fortunately the three occupants of the car escaped without injury. CORRESPONDENCE. *»* The name and address of the writer (not necessarily for publication) MUST in all cases accompany letters intended fo> insertion* or containing queries. Correspondents asking questions relating to articles which they have read in FLIGHT, would much facilitate our work of reference by kindly indicating the volume and page in their letters. NOTE.—Owing to the great mass of valuable and interesting corre spondence which we receive, immediate publication is impossible, but each letter will appear prcuticallv in sequence and at the earliest possible moment. PROPOSED MODEL AERO CLUB FOR LONDON. £346] It has been suggested that a model aero club be formed in London. There will, no doubt, be many of your readers who would like to join and if they will send me a stamped addressed postcard I will arrange a suitable meeting place, where the project may be discussed. 2, West Grove Terrace, A. C. HORTH. The Point, Blackheath, S.E. [We deal specially with the above proposal on our leader page. —En.] MODELS. l347l I have constructed a model monoplane of cane, the length of it is 25 ins., the main plane is 22 ins. by 6 ins., and the tail 10 ins. by 7 ins. The weight of it is 7 oz. The monoplane when sent from the hand glides very well. I have frequently got glides of 30 ft. to 40 ft. I was wondering if you or some of your readers could answer me the three following questions:— 1. Would an 8 in. propeller (tractor) be too large for it ? 2. I intend having my elastic motor about 18 ins. long. How many strands of - % elastic would be required to drive the model ? 3. When the elastic is wound up fully, for how many seconds should the propeller revolve ? Wishing FLIGHT every success, Blackpool. R. W. MAWDSLEY. [Questions such as those raised by our correspondent are at present unanswerable except by other readers who happen to have experimented with models of approximately the same size, and it is on the esprit-de-corps that has so characterised these pages ol FLIGHT that we rely for the assistance that is nominally of direct and immediate use to only one reader at the present time, but is of probable interest to a great many others. The numerous letters of appreciation that we have received on the subject show us that this co-operation in the present early days of the movement is being of great assistance to the furtherance of the progress of flight in England, and we feel sure that those who are so generously assisting others with the information that they have themselves obtained, possibly not without considerable trouble, will never regret their useful actions.—ED.] THE ROE TRIPLANE. [348] I was much interested in Mr. Roe's letter in a recent issue, and I think every credit is due to him for the plucky way in which he has stuck to his triplane. There is no doubt that had he received as much financial support as some of our Continental rivals he would have achieved earlier success. Personally I am no advocate of the triplane, because I do not think it can ever be designed so as to develop the extreme speeds which we may look for in the not very distant future ; but at the same time the triplane may be found to fill some useful purpose, and it would appear that Mr. Roe has actually flown with less power than is used on any other well-known type of machine. It would be very interesting to know—and I hope Mr. Roe will 113
