JO|HTJ general design it is a combination of the Bleriot and Hanriot type. It has a triangular girder body made of £-in. square section pine. The struts measure \ in. by \ in., and are fastened by fine brass nails and binding. The ribs of the planes are Jin. square section ash. steamed to the required camber and let into the spars. The spars themselves are $.in. by \ in. section, and the trailing edge of the planes is a -in. by J-in. strip of pine. The machine is supported on an A-type carriage, the general arrangement and con struction of which is sufficiently well illustrated in the drawing. The main spars are attached to the body by U-shaped bolts made of pieces of cycle spoke threaded at each end. A brass washer-plate is threaded over the U bolt before the nuts are put on. The carriage is supported on perambulator wheels. The engine is a i-S-h.p. motor, weighing n lbs., and it drives a laminated ^o-in. propeller that I made mvself. G. T. M. GARRARD. Some Hints Wanted. [1063! Would you be so kind as to answer a few queries through the medium of your invaluable paper. I have just •constructed a model aeroplane of my own design, of which I have made a rough plan and elevation. It is a tail first type. I should like to say it is a good glider, and it weighs 9 ozs. The main plane is cambered, and the centre of gravity is 2 ins. in front of the leading edge. It is fitted with a three-geared elastic motor of equal gear. The few queries I should be glad if you would answer are :— J &"i: '') What length should you recommend for the propel ler ? The one I have now is a very low-pitched 8-in. one. (2) How many yards of elastic ought I to use to enable it to fly, as at present it has not enough power to keep it in flight ? (3) I should be much obliged if you could suggest any improvement that I could make, as I am very anxious that I shall get it to fly well. Would adding any further surface help towards this, and if so, when- would you advise me to add it, as I am afraid to alter it in case I should spoil the gliding capabilities ? Perhaps some of your readers could help me over my difficulty, as they may have had similar models and faults. Sutton. J. A. PHIPPS. Aviators at Qreenmount and a Kite Query. [1064I 1 daresay some of your readers would be interested to know what it really was that appeared in the Daily Dispatch •of September 2nd, 1910, so I enclose photo of supposed 34 i"- biplane, which you will see at once is a kite, 12 ft. 6 ins. wide by 8 ft. 2 ins. high. So if you think it worthy of insertion you are at liberty to do so. I would like to know what length of cord and the angle •of the winning kites at the Wimbledon competition, if any *eader of FLIGHT has this information. Greenmount. S. HORROCKS.
