JyGHf di.-tance owing to its more efficient design, yet with the present W x T formula they are both given the same points on In the foimula — * - it is difficult to know what values to give /, g, T* x wy r x, andy. Again, time is much easier to measure than distance owing to wind velocity, which can, however, be allowed for ; or one might get a maximum duration and a speed test over a measured ioo yards. As it so happens, a day or so before receiving Mr. Burrell s com munication we had occasion to apply the formula to two models with whose capabilities we were well acquainted, and the result was extremely unsatisfactory. As it stands the formula cannot be applied indiscriminately to different types of models—there must be some common factor or factor?. We shall be pleased to hear further from our readers re the above. Replies In Brief. A. BURNS (Toronto).—We regret we do not know of such a motor as the one you ask for that we could really recommend, and we KITE AND MODEL AEROPLANE ASSOCIATION. Official Notices.

The first competition will commence at 2.30 sharp, for prizes, presented by Messrs. Krooke and Westhorp (see page 644 FLIGHT, July 13th, for full details), the second competition, for the best use a kite can be put to, will follow, after which the Junior Contest will take place (see page 804, FLIGHT, August 31st for full details). ... , „. , . . , Next Olficial Trials.—The next officially observed flights for registration of moi'el aeroplane performances for the purpose of establishing records will be held on Wimbledon Common on October 26th, at 3 o'clock, on the plain, Wimbledon side of the windmill. The trials will be for distance and duration, hand-launched or off ground, also for tractor screws, distance and duration, hand-launched or off the ground. It is hoped that there will be a good entry, especially for those off grc und as the official record is very low. _ The Royal Aero Club.—The committee of the Royal Aero Uub has appointed the Kite and Model Aeroplane Association the authority to govern models in this country for the year 1913.

Full details about Model Section will appear in these notices as soon as possible. 37, Victory Road, Wimbledon. W. H. AKEHURST, Hon. Sec. OCTOBER 12, 1912. are afraid you will experience considerable difficulty in securing one. Why don't you procure your motor first, and then build your model to suit it; this is the only practical way of doing it that we know of at present ? R. KEENLEYSIDE.—Certainly, write to the secretary. Not that we know of. J. A. GOODALL.—Yes, send full particulars, and we will publish them and photos later on. C. C. HORNER.—There are several points in your communication not yet clear. What do you mean by movable " floats ? " the model is not a hydro-aeroplane, also the description of these side " float like " planes, and how they are worked and made is very obscure. Kindly send further particulars and part drawings, not necessarily for publication. ACCACIO DA GAMA.—You will find those given in our advertise ment columns as suitable as any we know of. AHROMANIAE.—You should triangulate your A frame still further with internal bracing wires if it bends out as well as in. If in, only, you would probably find T-shaped wood stiffer. You can get it at Messrs. J. Bonn and Co. No, don't place rubber underneath. Your main plane should stiffen it at the place you mention $ ® MODEL CLUB DIARY AND REPORTS.

SEVERAL trials have been made with both " Beta" and " Delta " at Fatnborough during the past few days. On Wednesday week the latter was out and made one or two lengthy voyages with five passengers on board. She was also out on the following day and on Sunday and Monday. The " Beta" was tested on Saturday, and on Monday she took a crew of naval men from Sheerness for an instructional voyage. A New Scouting Dirigible. THE new baby dirigible designed by Mr. E. T. Willows, specially for naval scouting was tested at Farnborough on Tuesday. The design is generally similar to that of the dirigible with which Mr. Willows made his trip across the Channel, the car being suspended from a transverse beam slung beneath the envelope. Only a pilot and an observer are carried, and in its trials the dirigible showed itself capable of a speed in the neighbourhood of 50 miles an hour. The Work of "Parseval VI." THE "Parseval VI," which has been stationed at Lucerne for some time, finished her season on Saturday last, and was deflated. She was packed up and it is said that she will be sent to England. While at Lucerne she made twenty-five ascents and was in the air for an aggregate of 36 hrs. 20 mins., representing a distance covered of about 550 miles. The German Naval Zeppelin. THE Zeppelin cruiser built to the order of the German Admiralty had her first trial at Friedrichshafen on Monday last. On the first opportunity she will attempt a voyage of two hours' duration, which was one of the conditions of her acceptance by the Navy. A machine gun is to be fitted to the airship, which will, of course, also be equipped with wireless telegraphy. Three motors are fitted, each of 170-h.p. and driving two propellers, one pair of which is arranged in the fore part of the vessel while the other four are grouped aft. A kitchen is fitted up on the airship, and the heat in the exhaust from the motors is utilised for cooking purposes. Seven Months' Work with "Victoria Louise." AT the conclusion of her season's work a few figures have been published concerning the use made of the Zeppelin liner, " Victoria Louise" during the seven months she has been in commission. Altogether 183 excursions were made, the distance covered totalling to 25,680 kilometres, giving an average of 143 kilometres for each trip. The number of passengers carried total to 3,902, giving an average for each voyage of 21, not including the crew. Storm Damages Dirigible Shed. THE very severe storm which raged over Germany during the middle of last week caused a good deal of anxiety to those in charge of the Zeppelin dirigible " Hansa." Several portions of the shed in which she was housed at Fuhlsbuttel, near Hamburg, were torn away, while several planks were blown out of the side and it was feared the shed might collapse on the airship. Fortunately, however, this catastrophe was averted. A German Dirigible Harbour Closed. IT has been decided to pull down the dirigible shed, which was erected at Munich some time ago at a cost of ^4,000, to house a Parseval airship. The situation of the shed makes a landing so difficult that it is not worth while running the risk of disaster. The company which had leased the shed are moving to the north of Germany, where they will build an airship on Schutte-Lanz lines, specially designed for naval use. 924
